What is Data Recovery?
Data recovery refers to the rescue and recovery of data from equipment in the event of a malfunction or accidental erasure of files or folders on the hard disk due to external hard drive failure or inaccessible.
Learn how to recover and restore data immediately when external hard drives experience symptoms
Below are some data recovery and restoration methods that you can try on your own immediately if you experience symptoms with an external hard drive.
1. Verify the USB cable or AC adapter is connected properly.
Checking the Power Switch Lamp
Check Device Manager
Update external hard drive drivers to the latest version
Try Windows Error Checking
If you are experiencing problems such as external hard drives not being recognized or not being able to access them, and you want to resolve the problem immediately by yourself, proceed with the verification process.
1. Verify the USB cable or AC adapter is connected properly.
If the external hard drive is not recognized or does not work, it is necessary to check if the hard drive itself is the cause or the accessory is the cause.First, check if the USB cable or AC adapter is properly connected or disconnected.When checking the condition of the USB cable, do not use a USB hub, but connect the USB cable of the external hard drive directly to the computer to check the operation.If the USB cable is plugged in correctly but the external hard drive is not recognized, connecting it to another computer or connecting it to a different USB port will help determine if the problem is caused by the disk or USB cable.However, it is also important to recognize that reseating cables and reconnecting them to a personal computer in the event of any external HDD problems can worsen the condition of the device and cause data loss.If you want to perform data recovery on your external hard drive, try these tasks only once.If you have tried once and the problem has not been improved, you should give priority to stopping and consulting a professional restoration company.

https://www.adte.jp/rec/hdd/post-856/
On a daily basis, there are times when I suddenly cannot see the data in my computer or external hard drive, or I cannot access it.External hard drive connected to PC is not recognized or the hard drive inside the PC is loaded
2. Check the power switch lamp
If the external hard drive is not recognized or does not respond, check if the power switch is being pressed or if the power lamp is on.I often forget to press the power switch.If the power lamp is on, it indicates that the external hard drive is receiving power.
3. Check Device Manager
If the external hard drive fails and there is no problem connecting the USB cable, AC adapter, or power supply, consider the hard drive itself to be the cause.You can use Device Manager to determine if the external hard drive is recognized by your computer.
·Procedure to check the status of the hard drive using Device Manager
To Determine if the External Hard Drive Is Recognized Correctly by a Windows Computer
①Open the Windows Menu
②Open Device Manager
③Signs recognized if the external hard drive model number is displayed on the ′Disk Drive′
④If the external hard drive model number is not listed on the ′disk drive′, it is not recognized.
①Check to see if the hard drive is recognized in ~4.
If the external hard drive model number does not appear in Device Manager and the disk is not recognized, the external hard drive itself may have failed, so it is necessary to consider recovering and restoring the data in an appropriate way.
4. Update external hard drive drivers to the latest version
If you are able to verify that the external hard drive is detected on your computer using Device Manager, update the external hard drive driver to the latest version.There are many cases where old drivers lead to trouble.
5.Try Windows Error Checking
If you are using a Windows computer, you may be able to correct the problem by performing a hard drive error check yourself.However, Windows error checking is a recovery method that can only be tried when the hard drive is experiencing a mild logical failure.If you are unsure of the type of disability, stop and avoid proceeding with the operation should be avoided.
·How to use HDD error check ·Recovery flow using automatic repair
①View Folder → Click PC from the one displayed on the left
②Right-click the hard drive you want to check → View properties → Select the Tools tab
③Error Check → Check for errors on the drive Item → Click Check
④Error checks are initiated and scans are performed
⑤If an error is detected, a reboot is prompted to repair the file system.
⑥Rebooting will repair the system
中 Even if it′s a moderate or more logical fault or a minor fault, if you check the error when the HDD has a physical fault, it will warp and worsen the condition and cause severe physical failure, so you need to be careful.If you have any concerns, you should give priority to consulting a professional recovery company before attempting an error check.
Types of external hard drive failures and failures
If the external hard drive is experiencing some symptoms and appears to be faulty, you should be aware that the following failures and defects are common.
Failure or damage to the AC adapter or USB cable that came with an external hard drive.
Logical Failure on External Hard Drive
External Hard Drive Physical Failure
1. Failure or damage to the AC adapter or USB cable with an external hard drive.
If you experience symptoms or problems using an external hard drive, it may not be a disk failure, but it may be caused by damage to the attached AC adapter or USB cable that causes the external hard drive to not be recognized.In particular, USB cables can cause poor contact and deterioration of connectors by repeatedly connecting and reseating them to a personal computer.In addition, AC adapters can cause problems such as the HDD not moving or not responding if the power supply becomes unstable or disconnected due to aging.
2. Logical failure of external hard drive
Logical failure is a failure that occurs when a human error program, such as corruption of a recorded system or data, or when a problem occurs in a human error program, occurs, although there is no problem with the device itself such as a HDD.When a logical failure occurs, the disk is often operational and recognizable, and it is often difficult to notice the failure.If you don′t notice a failure and continue to use the device, it can not only increase the difficulty of recovering data, but it can also become difficult to recover itself.
3. Physical failure of external hard drive
A physical failure is a failure caused by a physical failure or corruption of recording media.A hard disk, such as an external hard drive, is made up of many parts, which can lead to problems or problems if the parts are broken.Physical impairment can also occur over time.If an external hard drive is experiencing a physical failure, disk opening and recovery is required in a dedicated environment, such as a clean room.It is difficult to restore or repair the data on your own, and if you are worried that the data stored on the disk will be important, missing or unable to retrieve it, consulting a professional data recovery company should be a priority.
Examples of external hard drive logical failures and considerations when recovering data
If the external hard drive is experiencing the following symptoms or defects, it is assumed that a logical failure has occurred.
I deleted files and data by mistake/I accidentally deleted them
Incorrectly formatted/initialized
get an error message
Computer does not boot, OS does not boot
Removed partitions
viral infection
data-overwritten
File system corruption or program file corruption
The lamp is on, but the files and folders cannot be read or accessed.
In addition, if the external hard drive experiences symptoms, you may be able to proceed with the operation.
1. I accidentally deleted files and data · I accidentally deleted files and data
If you accidentally delete or delete files or folders from recording media such as external hard drives, stop working or working immediately.It is important to turn off the equipment and not use it anyway.When you delete a file or folder, the data is invisible, but it is not completely gone and remains until it is overwritten.However, if you continue to energize, do not stop the operation, and proceed with the operation, the data will be overwritten more and more.As a result, not only does data recovery become more difficult, but it can also become more difficult to recover itself.After erasing the data on the external hard drive, if you realize that the data should not have been erased or was important, you should consult a specialized data recovery company.I wanted to do something about it myself, so if I downloaded or scanned the restoration software such as free software, the overwrite progresses, and I couldn′t retrieve the data I wanted, leading to sad and regrettable results.Let′s give priority to contacting the restoration company if you have any concerns.
2. Formatted and initialized incorrectly
Formatting (initialization) refers to restoring recording media, such as external hard drives, to the original factory condition.After formatting (initialization), all the data stored in the recording media disappears and cannot be taken out.When I formatted an external hard drive thinking that it had been backed up, I found that it had not been backed up or that important data had been included after initialization, and I often get into trouble after formatting (initialization).In the unlikely event of such a situation, let′s consult with the data recovery company as soon as possible.After formatting (initializing) the same as when the data was deleted by mistake, the data will be overwritten by continuing to energize, operate, and work.When you want to retrieve or recover data, the top priority is to stop.
3. Error Message Appears
′Do you want to format an external hard drive when connected to a computer or when in use?Must be formatted.′ ′Not accessible.US>An error message such as ′The file or directory is corrupted and cannot be read′ or a white error message may appear when the computer turns on a blue screen (blue screen).In this case, you may have experienced a logical, physical, or both failure of the hard drive itself, and you should be careful.I often get flustered when an error message is displayed.Be careful not to press ′Yes′ when asked, ′Do you want to format it?′If you format it, all the data in it will disappear.In addition, these error messages often result in physical failure of the disk itself, which can quickly deteriorate by turning off power, repeated reboots, and reseating cables.If the data you have saved is important, or if the HDD is also important, it is better to stop and give priority to consulting a specialized data recovery company.
US>4. Removed partitions
If you accidentally delete a partition in your hard drive, start by stopping.Be careful not to recreate the partition in a hurry to do something about it yourself.A partition refers to each area that is configured on a recording medium, such as a hard drive or SSD, divided on the data.If you accidentally delete a partition, you should avoid downloading free software or scanning with recovery software to restore it on your own.Data overwrite progresses and not only increases the level of difficulty of recovery, but it can also become difficult to recover itself.
5. Infection with the virus
If you have saved a virus-infected file, you may suddenly experience problems such as not being able to load or recognize an external hard drive.If you keep using it, the situation will become serious.Let′s prioritize turning off the power first.
6. Overwrite data · Save new data to the device
If you notice data overwriting, such as saving new data after formatting an external hard drive or overwriting a file by mistake, stop working immediately.The slower the operation and response, the greater the risk that something that could have been restored will become unrecoverable
7. File system corruption or program file corruption
File systems (management information) on recording media such as external hard drives may be abnormal or damaged.Recording media always writes some kind of data at startup or when reading data.Failure to successfully write data due to unsafe removal, sudden shutdown, power failure, etc. can result in file system and program file corruption.
8. The lamp is on, but the files and folders cannot be read or accessed.
When connecting an external hard drive to a computer, the lamp is lit, the hard drive is recognized, but the contents are not visible, and there may be symptoms such as not being able to load files and folders.This symptom can occur in either logical or physical failure.If you plug in and out of the cable or turn it off when you can′t read or access it, the condition will deteriorate and it will be difficult to recover, so it′s most important not to touch it.
9.Other than that, if the external hard drive experiences symptoms and you proceed with the operation,
In the event of a problem with an external hard drive, if you have downloaded the software for data recovery or overwritten the data, you should give priority to immediately.The top priority is to turn off the power so that the state remains the same.If you think that you can recover an external hard drive by yourself and proceed with it easily, the condition becomes serious, and not only does it increase the difficulty level of recovery, but it often becomes difficult to recover, and you often regret it.If you have any concerns or concerns, give priority to consulting with a company that provides data recovery services on the spot.Even if by any chance you are working on it or in the middle of it, you should contact a specialized restoration company.
Examples of external hard drive physical failure symptoms and data recovery considerations
If the external hard drive is experiencing the following symptoms or defects, it is assumed that a physical failure has occurred.
Not recognized, unable to read, no longer accessible
Drop, drop, make noise, hear unusual sounds
I can′t hear or move.
smell burning and strange
Water, coffee, etc. spilled, submerged, or caught fire
Equipment does not turn on/start
Error messages such as CRC errors are displayed.
External hard drive is hot
Something is wrong after a power outage or lightning strike.
if other symptoms appear
1. Not recognized, unable to read, no longer accessible
When an external hard drive is not recognized, it can often be a failure of the disk itself or damage to internal components.In addition, damage to accessories such as cables and USB terminals may cause symptoms.HDD is one of the most delicate precision instruments and is also a recording medium for consumables.Even if there was no problem until just a while ago, one day, problems such as external hard drive not recognizing, cannot read, and cannot access may occur suddenly.When the symptoms appear, you may be able to fix it by yourself if you turn it back on, or you may be able to turn it off and restart it repeatedly if you recognize it.However, such operations are very dangerous.The hard drive will deteriorate quickly if the power is turned on and off.As a result, not only does data recovery become more difficult, but it can also become more difficult to recover itself.If you think that data stored on an external hard drive is important or that you might be in trouble if it disappears, turn it off and turn it off first.
2. Drop it, drop it, make noise, hear unusual
External HDDs are one of the recording media that is easy to carry and often fails due to external factors.When dropped, dropped, or impacted, the internal parts may be broken or come off.If you continue to energize, turn off the power, or try restarting, the disk-shaped part called the Platter storing the data will be damaged.In the worst case scenario, the part containing the data itself may be deleted.When you drop it, you should turn it off immediately and contact a specialized data recovery company.If you drop, drop, or impact an external hard drive, it′s very dangerous to try to do something by yourself, and it′s a priority to unplug the cable so that it doesn′t get energized.

Have you ever had a problem with the sudden noise coming from your hard drive that you′ve never heard of before?Have you ever experienced noise that caused the hard drive to not recognize it, lost access, or had trouble using the stored data?
3. There is no moving sound and it does not moving
The external HDD lamp is turned on, connected to a personal computer, but no sound is heard, and when it is not working, it is estimated that the internal parts motor, power failure, and data recording platters are stuck with the data reading head.When these symptoms occur, data can often be recovered immediately if there is no damage to the platter.However, it is difficult to deal with it on your own, so be careful.To recover data from a non-moving HDD, it is necessary to open the disk and perform restoration and repair work. クリーン Dedicated facilities such as clean rooms 互換 Procurement of compatible specialized parts 深い Deep expertise 高度 Advanced technical capabilities are essential.If you need data from an external hard drive or want to recover quickly, cheaply and reliably, consult a specialized data recovery company.
4. It smells burning and strange
When connecting an external hard drive to a personal computer, be careful if you suddenly feel the noise, smoke, or smell burning.In such cases, it can lead to a fire, so try not to unplug the cable immediately and be energized.If you smell something strange, please ventilate as well.If these symptoms occur, the hard drive needs to be repaired.If you need data stored on disk, contact the data recovery service provider, and if you don′t need data, contact the manufacturer or the buyer to resolve the problem smoothly.
5. Water, coffee, etc. spilled, submerged, and caught fire
While working on a computer while drinking water, coffee, or soup, the liquid may spill on the computer or connected external HDD, and the equipment may be submerged and broken due to flooding on the floor caused by typhoons and floods.If you are in a situation where the equipment is damaged by an unexpected accident, natural disaster, or fire, you should consider contacting a specialized restoration company as soon as possible.
6. The device does not turn on and does not start.
Even if the external hard drive does not light up after the power is turned on or does not start, the disk itself is often physically damaged.If you can′t turn on the power after connecting to another computer or replacing the USB cable, think your hard drive is broken and move carefully.You should also avoid energizing the external hard drive if you think it is different from when it was working properly.If you continue to turn on the power without starting or turning on the power, the condition will deteriorate.If you can′t recover by yourself after trying it once, you should stop trying it and consult a professional restoration company.
7. Error messages such as CRC errors are displayed.
When an error message such as ′Data error (Circular Redundancy Check (CRC) error)′ appears, it is estimated that the hard drive itself has failed or that a physical failure has occurred.If you ignore the error message and continue to operate it, the situation will get worse and other symptoms will often occur, so you need to be careful.If data is important or you don′t want to lose it, stop when you get an error message.When an error message is issued, using a restoration software such as free software to recover by yourself can be a dangerous act of losing data.CRC errors, in particular, are one of the most common errors where the hard drive has failed physically, and using the restore software not only prevents data recovery, but also causes serious conditions.When you are in trouble due to an error, you should give priority to consulting a specialized data recovery company without doing anything unnecessary.

Some of you may be confused when you see a data error while using your computer.CRC errors (cyclic redundancy check errors) can occur when reading and writing data on recording media such as hard drives, USB memory, and SD cards.When CRC errors appear, be aware that the hard drive may experience severe symptoms or failures.In order not to lose the important data you have saved, here are some things you would like to know when CRC errors occur and how to repair them.
8. External Hard Drive is Hot
A hard drive is one of the recording media that tends to heat up.Equipment is sensitive to heat and often breaks down due to heat.Touch the external hard drive and stop using it immediately if you are experiencing problems such as hot or hot loading.
9. Something is wrong after a power outage or lightning strike.
When using an external hard drive connected to a PC, power supply problems due to unexpected power outages or lightning strikes are often caused by problems or failures in the equipment.If something goes wrong after an external hard drive or a personal computer fails to turn off properly due to a power outage or lightning strike, you should stop using the device any more.There are many serious data loss failures, and just trying to get back into use to do something by yourself can accelerate the deterioration of the situation.
10. If you experience any other symptoms,
The external hard drive has various symptoms.Even if you use it carefully, it is possible for anyone to have trouble due to aging.If you experience any symptoms or problems, consider stopping and contacting a professional data recovery service provider.If you contact them quickly, their worries and symptoms will be solved quickly, and the data will not disappear.In addition, if you rely on a professional, you will be able to reduce the restoration fee as a result.For those who want to keep costs low, let′s prioritize using free consultations from restoration companies.
How do I recover or restore data on an external hard drive?
In the event of an external hard drive failure or failure, depending on whether you want to recover (restore) the data on the hard drive or if you don′t need the data and return to the device for use.′For those who value or need data, go to the ′′Data Recovery Service Provider.′′′′′If you don′t need data and only want to repair the equipment, consider consulting with the ′buyer or manufacturer.′

You want to restore data on your external hard drive on your own.
How to consult with a data recovery/restoration service provider
1. How to consult with the purchasing store or manufacturer
If you don′t need the data on an external hard drive and want to repair the disk itself and fix it for use again, or if it works, consider consulting with the store or manufacturer.If you ask the store or manufacturer to repair it, it is necessary to understand that the stored data is not guaranteed and that the data will disappear or disappear.This is because it is often initialized or replaced with another new hard drive when it is repaired.In the first place, the purpose of repair is to repair the broken or defective recording media body and internal parts and to return them to a usable state.If you want to prioritize recovering or rescuing the data inside rather than returning to the HDD, you should consider other options.
2. How to use data recovery and restoration software (free software or paid software)
If you want to recover or retrieve data stored on an external hard drive in the event of a problem with an external hard drive, you can use the recovery software.
·Examples of the benefits of attempting to restore data on external HDDs using recovery software
①be sometimes relatively easy to use
②have the potential to be able to recover quickly
·Examples of disadvantages of attempting to restore data on external HDDs using recovery software
①Recovery software is not available if external hard drive is experiencing physical failure
②Downloading and scanning recovery software such as free software in the event of a physical failure often puts a strain on the system and results in severe conditions.
③Data is often overwritten by using recovery software even in the event of a logical failure.
④In many cases, restoration becomes more difficult as a result of using restoration software.
⑤When the external hard drive is about to break, the recovery software will break completely.
⑥The manual is often introduced only in English, so I have more worries.
⑦Even with recovery software, not only can we not repair errors and troubles, but it is often so bad that the recovery itself becomes difficult.
and so on.Recovery software can handle only minor logical failures, but it is difficult to understand the type of external HDD failure, the degree of failure (mild, moderate, severe, etc.) and the damage by itself.Even if you think it′s light, there are many cases where symptoms and failures have progressed, so you should avoid using the data recovery software when you think that the data stored on the external HDD is important, that it might be difficult to lose, or that you don′t want to fail.If you really want to use the recovery software by yourself, you won′t have to regret it if you consult a professional data recovery service provider first.·Things that need to be prepared in advance to use the restoration software

3. If you want to restore data from an external hard drive on your own,
If you want to recover data from an external hard drive on your own, follow these steps:
Find data recovery software for external hard drives
install software on a PC
Connect an external hard drive to a PC
Scan an External Hard Drive
select data, press repair button
review restored data
*If you cannot find the files or folders you want to restore in 5. or feel a little uneasy, stop working.
パーティ If the entire partition is lost, you will need to find the data in the lost partition.It is often dangerous to continue the operation without knowing it well.If you have any concerns, stop the operation.
Even if you use the recovery software, the restoration of files and folders you want is limited, the restoration of data is only partially done, and the file name is often garbled.It is important to stop the operation when you are looking for the recovery software or when you are having trouble or trouble during the download scan.Unfortunately, there may be cases where the software overwrites the data and makes it difficult to recover.If you have important data stored on an external hard drive, you may be in trouble if it disappears, or if you don′t want to fail, you should consult a professional data recovery company before using the restore software.Also, if you leave it to a professional, the restoration fee is often reduced.
4. How to consult with a data recovery and restoration service provider
If you need data from an external hard drive or want to retrieve it safely, you can consult a professional data recovery company.When you consult with a data recovery specialist, you have the expertise and expertise to identify the cause, location, and type of failure that has occurred, enabling you to respond to logical or physical failures.However, there are many data recovery companies, so if you have any concerns, such as not knowing which company to choose, check if they have AI technology or proprietary technology.It is the standard for choosing a company with high technical capabilities.Please note that it is not possible for any company to recover in the same way.There is also a big difference in the service content and technical capabilities of each company.By any chance, if you send it to a restoration company without technical capabilities, not only will you not be able to recover the data, but the condition may deteriorate.For this reason, when you think that the data in the external HDD is important, that it will be a problem if it disappears, or that you don′t want to fail, you need to select the recovery company you want to consult with first.Because it was displayed in the top position in the search, if you choose easily because it is close to your house or office, you may regret it.If you can′t send it to one company, don′t think you can send it to the next company.
How to Choose a Data Recovery Service Provider
When external hard drives experience symptoms or malfunctions, they often panic.If you have any concerns, you should give priority to consulting a professional data recovery company.If you are having trouble with which restoration company to contact, it will be easier to make a decision by checking the following points.
Do you have high technical capabilities (with or without AI technology or proprietary technology)?
Is the speed and response speed fast?
Does the institution specify restoration costs, fee plans, etc.
Is confidentiality and control of information thorough?
Does the organization have a specialized environment such as a clean room?
Whether or not we have been able to handle this way
If the data contained in the external HDD is important, you want to fix it quickly, minimize disruption to your business, you′ll be in trouble if you can′t retrieve the data, worry about the cost of recovery, and so on, you should consult a data recovery service company.Advanced technology meets all 1-6 requirements and is a recommended data recovery company.Advanced technology enables rapid response and low-cost data recovery.Let′s prioritize using free consultation from a data recovery service company when you′re in trouble.
Don′t do it when you need to recover data from an external hard drive.
There are a few things to be careful about and not to do if you want to recover or restore data when an external hard drive is suspected to be faulty or malfunctioning.If data is important or you want to reduce recovery costs, let′s check the items below before moving.
Repeated power ON/OFF and reboot are not allowed.
Do not keep the power running · Do not leave the cable connected
without initialization or formatting
unbreakable
Avoid using Windows Check Disk (chkdsk)
Don′t force yourself to recover data
1. Repeated power ON/OFF and reboot are not allowed.
Avoid turning the power on and off repeatedly or restarting when the external hard drive is not recognized, data is inaccessible, or when there is a suspected failure.Power cycling or rebooting is one of the most stressful activities for recording media and personal computers, including external hard drives.If you turn off the power or reboot several times to do something by yourself when there is a problem or trouble, the condition often becomes serious.As a result of doing what you can easily do, recovery itself becomes more difficult and there is an increased risk of data loss.Let′s be careful.
2. Do not keep the power running · Do not leave the cable connected
If you think your external hard drive may have broken or you experience any symptoms, turn it off and avoid continuing to power on.If you continue to energize in the event of a failure, it can often cause damage to the parts like needles that read data in the hard drive, or to the platter surface where the magnetic head is working to record the data.Also, in some cases, the part where the data is recorded on the platter is cut off, and in some cases, things that could have been recovered by doing things that could have been easily done, such as continuing to energize, may end up in an unrecoverable.It′s important to turn off the power so that the electricity doesn′t go through when there′s some trouble.In the case of an external hard drive, if you leave the cable plugged into the computer, the electricity will continue to flow, so if there is a problem, try to unplug the cable.
3. Do not initialize or format
When connecting an external hard drive to a computer, you should also be careful when an error message such as ′Must be formatted′ appears.If you format it in a hurry, all the stored data will disappear.Formatting or initializing is the process of restoring equipment to its original factory condition.If you accidentally format it, contact your data recovery service provider immediately.If you do something after formatting or initializing, or if you run the recovery software yourself, the data will continue to be overwritten.Not only does it increase the difficulty of recovering data, but it is often difficult to recover itself, so you don′t have to regret it if you consult with them right away.
4. Do not decompose
If you have trouble with your external hard drive, you may want to find out the cause.However, do not tear down recording media such as hard disks.HDD is a very delicate precision device.Even if a little dust or small dust gets in, it breaks down quickly.Therefore, when dismantling or opening a hard disk, it is necessary to use a dedicated facility such as a clean room.If you break it apart under normal conditions, such as in the office or in the home, dust and dust will go inside and stick to the platters in the disk.As a result, it causes scratches on the platters and increases the risk of losing data.In addition, external HDDs are not built on the premise that they will be disassembled, and if they are disassembled by individuals, they will not be covered by the manufacturer′s warranty.Also, even though it was possible to recover, it may be impossible to recover because it was broken down by itself.Let′s not take it apart.
5. Avoid using Windows Check Disk (chkdsk)
If an external hard drive is connected to a Windows computer and an error occurs, you may want to use the Check Disk (chkdsk) tool to repair it or think that you can recover it yourself.However, this ′chkdsk′ is a tool that repairs Windows to the appropriate file system, so it does not check for errors on external media such as external hard drives or recover data in the event of a problem.′Also, if ′′chkdsk′′ is implemented, all data that ′′chkdsk′′ recognizes as an error will be truncated, and the recovery itself may become difficult because the data will be overwritten.′′Also, ′′chkdsk′′ takes a lot of time to read and write, which puts a lot of strain on the recording media.′It is recommended to avoid using chkdsk because it promotes serious conditions.
6. Don′t force yourself to proceed with the data recovery process.
If an external hard drive fails or fails, careful attention is required.If you download or scan your own data recovery software and the data is overwritten, or if the platters that record the data inside your hard disk are slightly damaged, it will not be restored.A hard disk is a delicate device and one of the consumables.If the failure condition deteriorates, the data will disappear and the recovery itself may become difficult.If you want to try what you can do or think you can do something about it, you should give priority to stopping first.If you really want to recover by yourself, consult a professional data recovery service provider before proceeding, so you don′t have to regret it.
Example of an external hard drive manufacturer
Various manufacturers manufacture and sell external HDDs, but any manufacturer′s products can cause problems or problems suddenly.If your data is important or you want to restore it, contact a professional data recovery service provider first.

What is Data Recovery?
Data recovery refers to the rescue and recovery of data from equipment in the event of a malfunction or accidental erasure of files or folders on the hard disk due to external hard drive failure or inaccessible.
Learn how to recover and restore data immediately when external hard drives experience symptoms
Below are some data recovery and restoration methods that you can try on your own immediately if you experience symptoms with an external hard drive.
1. Verify the USB cable or AC adapter is connected properly.
Checking the Power Switch Lamp
Check Device Manager
Update external hard drive drivers to the latest version
Try Windows Error Checking
If you are experiencing problems such as external hard drives not being recognized or not being able to access them, and you want to resolve the problem immediately by yourself, proceed with the verification process.
1. Verify the USB cable or AC adapter is connected properly.
If the external hard drive is not recognized or does not work, it is necessary to check if the hard drive itself is the cause or the accessory is the cause.First, check if the USB cable or AC adapter is properly connected or disconnected.When checking the condition of the USB cable, do not use a USB hub, but connect the USB cable of the external hard drive directly to the computer to check the operation.If the USB cable is plugged in correctly but the external hard drive is not recognized, connecting it to another computer or connecting it to a different USB port will help determine if the problem is caused by the disk or USB cable.However, it is also important to recognize that reseating cables and reconnecting them to a personal computer in the event of any external HDD problems can worsen the condition of the device and cause data loss.If you want to perform data recovery on your external hard drive, try these tasks only once.If you have tried once and the problem has not been improved, you should give priority to stopping and consulting a professional restoration company.

https://www.adte.jp/rec/hdd/post-856/
On a daily basis, there are times when I suddenly cannot see the data in my computer or external hard drive, or I cannot access it.External hard drive connected to PC is not recognized or the hard drive inside the PC is loaded
2. Check the power switch lamp
If the external hard drive is not recognized or does not respond, check if the power switch is being pressed or if the power lamp is on.I often forget to press the power switch.If the power lamp is on, it indicates that the external hard drive is receiving power.
3. Check Device Manager
If the external hard drive fails and there is no problem connecting the USB cable, AC adapter, or power supply, consider the hard drive itself to be the cause.You can use Device Manager to determine if the external hard drive is recognized by your computer.
·Procedure to check the status of the hard drive using Device Manager
To Determine if the External Hard Drive Is Recognized Correctly by a Windows Computer
①Open the Windows Menu
②Open Device Manager
③Signs recognized if the external hard drive model number is displayed on the ′Disk Drive′
④If the external hard drive model number is not listed on the ′disk drive′, it is not recognized.
①Check to see if the hard drive is recognized in ~4.
If the external hard drive model number does not appear in Device Manager and the disk is not recognized, the external hard drive itself may have failed, so it is necessary to consider recovering and restoring the data in an appropriate way.
4. Update external hard drive drivers to the latest version
If you are able to verify that the external hard drive is detected on your computer using Device Manager, update the external hard drive driver to the latest version.There are many cases where old drivers lead to trouble.
5.Try Windows Error Checking
If you are using a Windows computer, you may be able to correct the problem by performing a hard drive error check yourself.However, Windows error checking is a recovery method that can only be tried when the hard drive is experiencing a mild logical failure.If you are unsure of the type of disability, stop and avoid proceeding with the operation should be avoided.
·How to use HDD error check ·Recovery flow using automatic repair
①View Folder → Click PC from the one displayed on the left
②Right-click the hard drive you want to check → View properties → Select the Tools tab
③Error Check → Check for errors on the drive Item → Click Check
④Error checks are initiated and scans are performed
⑤If an error is detected, a reboot is prompted to repair the file system.
⑥Rebooting will repair the system
中 Even if it′s a moderate or more logical fault or a minor fault, if you check the error when the HDD has a physical fault, it will warp and worsen the condition and cause severe physical failure, so you need to be careful.If you have any concerns, you should give priority to consulting a professional recovery company before attempting an error check.
Types of external hard drive failures and failures
If the external hard drive is experiencing some symptoms and appears to be faulty, you should be aware that the following failures and defects are common.
Failure or damage to the AC adapter or USB cable that came with an external hard drive.
Logical Failure on External Hard Drive
External Hard Drive Physical Failure
1. Failure or damage to the AC adapter or USB cable with an external hard drive.
If you experience symptoms or problems using an external hard drive, it may not be a disk failure, but it may be caused by damage to the attached AC adapter or USB cable that causes the external hard drive to not be recognized.In particular, USB cables can cause poor contact and deterioration of connectors by repeatedly connecting and reseating them to a personal computer.In addition, AC adapters can cause problems such as the HDD not moving or not responding if the power supply becomes unstable or disconnected due to aging.
2. Logical failure of external hard drive
Logical failure is a failure that occurs when a human error program, such as corruption of a recorded system or data, or when a problem occurs in a human error program, occurs, although there is no problem with the device itself such as a HDD.When a logical failure occurs, the disk is often operational and recognizable, and it is often difficult to notice the failure.If you don′t notice a failure and continue to use the device, it can not only increase the difficulty of recovering data, but it can also become difficult to recover itself.
3. Physical failure of external hard drive
A physical failure is a failure caused by a physical failure or corruption of recording media.A hard disk, such as an external hard drive, is made up of many parts, which can lead to problems or problems if the parts are broken.Physical impairment can also occur over time.If an external hard drive is experiencing a physical failure, disk opening and recovery is required in a dedicated environment, such as a clean room.It is difficult to restore or repair the data on your own, and if you are worried that the data stored on the disk will be important, missing or unable to retrieve it, consulting a professional data recovery company should be a priority.
Examples of external hard drive logical failures and considerations when recovering data
If the external hard drive is experiencing the following symptoms or defects, it is assumed that a logical failure has occurred.
I deleted files and data by mistake/I accidentally deleted them
Incorrectly formatted/initialized
get an error message
Computer does not boot, OS does not boot
Removed partitions
viral infection
data-overwritten
File system corruption or program file corruption
The lamp is on, but the files and folders cannot be read or accessed.
In addition, if the external hard drive experiences symptoms, you may be able to proceed with the operation.
1. I accidentally deleted files and data · I accidentally deleted files and data
If you accidentally delete or delete files or folders from recording media such as external hard drives, stop working or working immediately.It is important to turn off the equipment and not use it anyway.When you delete a file or folder, the data is invisible, but it is not completely gone and remains until it is overwritten.However, if you continue to energize, do not stop the operation, and proceed with the operation, the data will be overwritten more and more.As a result, not only does data recovery become more difficult, but it can also become more difficult to recover itself.After erasing the data on the external hard drive, if you realize that the data should not have been erased or was important, you should consult a specialized data recovery company.I wanted to do something about it myself, so if I downloaded or scanned the restoration software such as free software, the overwrite progresses, and I couldn′t retrieve the data I wanted, leading to sad and regrettable results.Let′s give priority to contacting the restoration company if you have any concerns.
2. Formatted and initialized incorrectly
Formatting (initialization) refers to restoring recording media, such as external hard drives, to the original factory condition.After formatting (initialization), all the data stored in the recording media disappears and cannot be taken out.When I formatted an external hard drive thinking that it had been backed up, I found that it had not been backed up or that important data had been included after initialization, and I often get into trouble after formatting (initialization).In the unlikely event of such a situation, let′s consult with the data recovery company as soon as possible.After formatting (initializing) the same as when the data was deleted by mistake, the data will be overwritten by continuing to energize, operate, and work.When you want to retrieve or recover data, the top priority is to stop.
3. Error Message Appears
′Do you want to format an external hard drive when connected to a computer or when in use?Must be formatted.′ ′Not accessible.US>An error message such as ′The file or directory is corrupted and cannot be read′ or a white error message may appear when the computer turns on a blue screen (blue screen).In this case, you may have experienced a logical, physical, or both failure of the hard drive itself, and you should be careful.I often get flustered when an error message is displayed.Be careful not to press ′Yes′ when asked, ′Do you want to format it?′If you format it, all the data in it will disappear.In addition, these error messages often result in physical failure of the disk itself, which can quickly deteriorate by turning off power, repeated reboots, and reseating cables.If the data you have saved is important, or if the HDD is also important, it is better to stop and give priority to consulting a specialized data recovery company.
US>4. Removed partitions
If you accidentally delete a partition in your hard drive, start by stopping.Be careful not to recreate the partition in a hurry to do something about it yourself.A partition refers to each area that is configured on a recording medium, such as a hard drive or SSD, divided on the data.If you accidentally delete a partition, you should avoid downloading free software or scanning with recovery software to restore it on your own.Data overwrite progresses and not only increases the level of difficulty of recovery, but it can also become difficult to recover itself.
5. Infection with the virus
If you have saved a virus-infected file, you may suddenly experience problems such as not being able to load or recognize an external hard drive.If you keep using it, the situation will become serious.Let′s prioritize turning off the power first.
6. Overwrite data · Save new data to the device
If you notice data overwriting, such as saving new data after formatting an external hard drive or overwriting a file by mistake, stop working immediately.The slower the operation and response, the greater the risk that something that could have been restored will become unrecoverable
7. File system corruption or program file corruption
File systems (management information) on recording media such as external hard drives may be abnormal or damaged.Recording media always writes some kind of data at startup or when reading data.Failure to successfully write data due to unsafe removal, sudden shutdown, power failure, etc. can result in file system and program file corruption.
8. The lamp is on, but the files and folders cannot be read or accessed.
When connecting an external hard drive to a computer, the lamp is lit, the hard drive is recognized, but the contents are not visible, and there may be symptoms such as not being able to load files and folders.This symptom can occur in either logical or physical failure.If you plug in and out of the cable or turn it off when you can′t read or access it, the condition will deteriorate and it will be difficult to recover, so it′s most important not to touch it.
9.Other than that, if the external hard drive experiences symptoms and you proceed with the operation,
In the event of a problem with an external hard drive, if you have downloaded the software for data recovery or overwritten the data, you should give priority to immediately.The top priority is to turn off the power so that the state remains the same.If you think that you can recover an external hard drive by yourself and proceed with it easily, the condition becomes serious, and not only does it increase the difficulty level of recovery, but it often becomes difficult to recover, and you often regret it.If you have any concerns or concerns, give priority to consulting with a company that provides data recovery services on the spot.Even if by any chance you are working on it or in the middle of it, you should contact a specialized restoration company.
Examples of external hard drive physical failure symptoms and data recovery considerations
If the external hard drive is experiencing the following symptoms or defects, it is assumed that a physical failure has occurred.
Not recognized, unable to read, no longer accessible
Drop, drop, make noise, hear unusual sounds
I can′t hear or move.
smell burning and strange
Water, coffee, etc. spilled, submerged, or caught fire
Equipment does not turn on/start
Error messages such as CRC errors are displayed.
External hard drive is hot
Something is wrong after a power outage or lightning strike.
if other symptoms appear
1. Not recognized, unable to read, no longer accessible
When an external hard drive is not recognized, it can often be a failure of the disk itself or damage to internal components.In addition, damage to accessories such as cables and USB terminals may cause symptoms.HDD is one of the most delicate precision instruments and is also a recording medium for consumables.Even if there was no problem until just a while ago, one day, problems such as external hard drive not recognizing, cannot read, and cannot access may occur suddenly.When the symptoms appear, you may be able to fix it by yourself if you turn it back on, or you may be able to turn it off and restart it repeatedly if you recognize it.However, such operations are very dangerous.The hard drive will deteriorate quickly if the power is turned on and off.As a result, not only does data recovery become more difficult, but it can also become more difficult to recover itself.If you think that data stored on an external hard drive is important or that you might be in trouble if it disappears, turn it off and turn it off first.
2. Drop it, drop it, make noise, hear unusual
External HDDs are one of the recording media that is easy to carry and often fails due to external factors.When dropped, dropped, or impacted, the internal parts may be broken or come off.If you continue to energize, turn off the power, or try restarting, the disk-shaped part called the Platter storing the data will be damaged.In the worst case scenario, the part containing the data itself may be deleted.When you drop it, you should turn it off immediately and contact a specialized data recovery company.If you drop, drop, or impact an external hard drive, it′s very dangerous to try to do something by yourself, and it′s a priority to unplug the cable so that it doesn′t get energized.

Have you ever had a problem with the sudden noise coming from your hard drive that you′ve never heard of before?Have you ever experienced noise that caused the hard drive to not recognize it, lost access, or had trouble using the stored data?
3. There is no moving sound and it does not moving
The external HDD lamp is turned on, connected to a personal computer, but no sound is heard, and when it is not working, it is estimated that the internal parts motor, power failure, and data recording platters are stuck with the data reading head.When these symptoms occur, data can often be recovered immediately if there is no damage to the platter.However, it is difficult to deal with it on your own, so be careful.To recover data from a non-moving HDD, it is necessary to open the disk and perform restoration and repair work. クリーン Dedicated facilities such as clean rooms 互換 Procurement of compatible specialized parts 深い Deep expertise 高度 Advanced technical capabilities are essential.If you need data from an external hard drive or want to recover quickly, cheaply and reliably, consult a specialized data recovery company.
4. It smells burning and strange
When connecting an external hard drive to a personal computer, be careful if you suddenly feel the noise, smoke, or smell burning.In such cases, it can lead to a fire, so try not to unplug the cable immediately and be energized.If you smell something strange, please ventilate as well.If these symptoms occur, the hard drive needs to be repaired.If you need data stored on disk, contact the data recovery service provider, and if you don′t need data, contact the manufacturer or the buyer to resolve the problem smoothly.
5. Water, coffee, etc. spilled, submerged, and caught fire
While working on a computer while drinking water, coffee, or soup, the liquid may spill on the computer or connected external HDD, and the equipment may be submerged and broken due to flooding on the floor caused by typhoons and floods.If you are in a situation where the equipment is damaged by an unexpected accident, natural disaster, or fire, you should consider contacting a specialized restoration company as soon as possible.
6. The device does not turn on and does not start.
Even if the external hard drive does not light up after the power is turned on or does not start, the disk itself is often physically damaged.If you can′t turn on the power after connecting to another computer or replacing the USB cable, think your hard drive is broken and move carefully.You should also avoid energizing the external hard drive if you think it is different from when it was working properly.If you continue to turn on the power without starting or turning on the power, the condition will deteriorate.If you can′t recover by yourself after trying it once, you should stop trying it and consult a professional restoration company.
7. Error messages such as CRC errors are displayed.
When an error message such as ′Data error (Circular Redundancy Check (CRC) error)′ appears, it is estimated that the hard drive itself has failed or that a physical failure has occurred.If you ignore the error message and continue to operate it, the situation will get worse and other symptoms will often occur, so you need to be careful.If data is important or you don′t want to lose it, stop when you get an error message.When an error message is issued, using a restoration software such as free software to recover by yourself can be a dangerous act of losing data.CRC errors, in particular, are one of the most common errors where the hard drive has failed physically, and using the restore software not only prevents data recovery, but also causes serious conditions.When you are in trouble due to an error, you should give priority to consulting a specialized data recovery company without doing anything unnecessary.

Some of you may be confused when you see a data error while using your computer.CRC errors (cyclic redundancy check errors) can occur when reading and writing data on recording media such as hard drives, USB memory, and SD cards.When CRC errors appear, be aware that the hard drive may experience severe symptoms or failures.In order not to lose the important data you have saved, here are some things you would like to know when CRC errors occur and how to repair them.
8. External Hard Drive is Hot
A hard drive is one of the recording media that tends to heat up.Equipment is sensitive to heat and often breaks down due to heat.Touch the external hard drive and stop using it immediately if you are experiencing problems such as hot or hot loading.
9. Something is wrong after a power outage or lightning strike.
When using an external hard drive connected to a PC, power supply problems due to unexpected power outages or lightning strikes are often caused by problems or failures in the equipment.If something goes wrong after an external hard drive or a personal computer fails to turn off properly due to a power outage or lightning strike, you should stop using the device any more.There are many serious data loss failures, and just trying to get back into use to do something by yourself can accelerate the deterioration of the situation.
10. If you experience any other symptoms,
The external hard drive has various symptoms.Even if you use it carefully, it is possible for anyone to have trouble due to aging.If you experience any symptoms or problems, consider stopping and contacting a professional data recovery service provider.If you contact them quickly, their worries and symptoms will be solved quickly, and the data will not disappear.In addition, if you rely on a professional, you will be able to reduce the restoration fee as a result.For those who want to keep costs low, let′s prioritize using free consultations from restoration companies.
How do I recover or restore data on an external hard drive?
In the event of an external hard drive failure or failure, depending on whether you want to recover (restore) the data on the hard drive or if you don′t need the data and return to the device for use.′For those who value or need data, go to the ′′Data Recovery Service Provider.′′′′′If you don′t need data and only want to repair the equipment, consider consulting with the ′buyer or manufacturer.′
How to consult with a buyer or manufacturer

You want to restore data on your external hard drive on your own.
How to consult with a data recovery/restoration service provider
1. How to consult with the purchasing store or manufacturer
If you don′t need the data on an external hard drive and want to repair the disk itself and fix it for use again, or if it works, consider consulting with the store or manufacturer.If you ask the store or manufacturer to repair it, it is necessary to understand that the stored data is not guaranteed and that the data will disappear or disappear.This is because it is often initialized or replaced with another new hard drive when it is repaired.In the first place, the purpose of repair is to repair the broken or defective recording media body and internal parts and to return them to a usable state.If you want to prioritize recovering or rescuing the data inside rather than returning to the HDD, you should consider other options.
2. How to use data recovery and restoration software (free software or paid software)
If you want to recover or retrieve data stored on an external hard drive in the event of a problem with an external hard drive, you can use the recovery software.
·Examples of the benefits of attempting to restore data on external HDDs using recovery software
①be sometimes relatively easy to use
②have the potential to be able to recover quickly
·Examples of disadvantages of attempting to restore data on external HDDs using recovery software
①Recovery software is not available if external hard drive is experiencing physical failure
②Downloading and scanning recovery software such as free software in the event of a physical failure often puts a strain on the system and results in severe conditions.
③Data is often overwritten by using recovery software even in the event of a logical failure.
④In many cases, restoration becomes more difficult as a result of using restoration software.
⑤When the external hard drive is about to break, the recovery software will break completely.
⑥The manual is often introduced only in English, so I have more worries.
⑦Even with recovery software, not only can we not repair errors and troubles, but it is often so bad that the recovery itself becomes difficult.
and so on.Recovery software can handle only minor logical failures, but it is difficult to understand the type of external HDD failure, the degree of failure (mild, moderate, severe, etc.) and the damage by itself.Even if you think it′s light, there are many cases where symptoms and failures have progressed, so you should avoid using the data recovery software when you think that the data stored on the external HDD is important, that it might be difficult to lose, or that you don′t want to fail.If you really want to use the recovery software by yourself, you won′t have to regret it if you consult a professional data recovery service provider first.·Things that need to be prepared in advance to use the restoration software

3. If you want to restore data from an external hard drive on your own,
If you want to recover data from an external hard drive on your own, follow these steps:
Find data recovery software for external hard drives
install software on a PC
Connect an external hard drive to a PC
Scan an External Hard Drive
select data, press repair button
review restored data
*If you cannot find the files or folders you want to restore in 5. or feel a little uneasy, stop working.
パーティ If the entire partition is lost, you will need to find the data in the lost partition.It is often dangerous to continue the operation without knowing it well.If you have any concerns, stop the operation.
Even if you use the recovery software, the restoration of files and folders you want is limited, the restoration of data is only partially done, and the file name is often garbled.It is important to stop the operation when you are looking for the recovery software or when you are having trouble or trouble during the download scan.Unfortunately, there may be cases where the software overwrites the data and makes it difficult to recover.If you have important data stored on an external hard drive, you may be in trouble if it disappears, or if you don′t want to fail, you should consult a professional data recovery company before using the restore software.Also, if you leave it to a professional, the restoration fee is often reduced.
4. How to consult with a data recovery and restoration service provider

Don′t do it when you need to recover data from an external hard drive.
There are a few things to be careful about and not to do if you want to recover or restore data when an external hard drive is suspected to be faulty or malfunctioning.If data is important or you want to reduce recovery costs, let′s check the items below before moving.
Repeated power ON/OFF and reboot are not allowed.
Do not keep the power running · Do not leave the cable connected
without initialization or formatting
unbreakable
Avoid using Windows Check Disk (chkdsk)
Don′t force yourself to recover data
1. Repeated power ON/OFF and reboot are not allowed.
Avoid turning the power on and off repeatedly or restarting when the external hard drive is not recognized, data is inaccessible, or when there is a suspected failure.Power cycling or rebooting is one of the most stressful activities for recording media and personal computers, including external hard drives.If you turn off the power or reboot several times to do something by yourself when there is a problem or trouble, the condition often becomes serious.As a result of doing what you can easily do, recovery itself becomes more difficult and there is an increased risk of data loss.Let′s be careful.
2. Do not keep the power running · Do not leave the cable connected
If you think your external hard drive may have broken or you experience any symptoms, turn it off and avoid continuing to power on.If you continue to energize in the event of a failure, it can often cause damage to the parts like needles that read data in the hard drive, or to the platter surface where the magnetic head is working to record the data.Also, in some cases, the part where the data is recorded on the platter is cut off, and in some cases, things that could have been recovered by doing things that could have been easily done, such as continuing to energize, may end up in an unrecoverable.It′s important to turn off the power so that the electricity doesn′t go through when there′s some trouble.In the case of an external hard drive, if you leave the cable plugged into the computer, the electricity will continue to flow, so if there is a problem, try to unplug the cable.
3. Do not initialize or format
When connecting an external hard drive to a computer, you should also be careful when an error message such as ′Must be formatted′ appears.If you format it in a hurry, all the stored data will disappear.Formatting or initializing is the process of restoring equipment to its original factory condition.If you accidentally format it, contact your data recovery service provider immediately.If you do something after formatting or initializing, or if you run the recovery software yourself, the data will continue to be overwritten.Not only does it increase the difficulty of recovering data, but it is often difficult to recover itself, so you don′t have to regret it if you consult with them right away.
4. Do not decompose
If you have trouble with your external hard drive, you may want to find out the cause.However, do not tear down recording media such as hard disks.HDD is a very delicate precision device.Even if a little dust or small dust gets in, it breaks down quickly.Therefore, when dismantling or opening a hard disk, it is necessary to use a dedicated facility such as a clean room.If you break it apart under normal conditions, such as in the office or in the home, dust and dust will go inside and stick to the platters in the disk.As a result, it causes scratches on the platters and increases the risk of losing data.In addition, external HDDs are not built on the premise that they will be disassembled, and if they are disassembled by individuals, they will not be covered by the manufacturer′s warranty.Also, even though it was possible to recover, it may be impossible to recover because it was broken down by itself.Let′s not take it apart.
5. Avoid using Windows Check Disk (chkdsk)
If an external hard drive is connected to a Windows computer and an error occurs, you may want to use the Check Disk (chkdsk) tool to repair it or think that you can recover it yourself.However, this ′chkdsk′ is a tool that repairs Windows to the appropriate file system, so it does not check for errors on external media such as external hard drives or recover data in the event of a problem.′Also, if ′′chkdsk′′ is implemented, all data that ′′chkdsk′′ recognizes as an error will be truncated, and the recovery itself may become difficult because the data will be overwritten.′′Also, ′′chkdsk′′ takes a lot of time to read and write, which puts a lot of strain on the recording media.′It is recommended to avoid using chkdsk because it promotes serious conditions.
6. Don′t force yourself to proceed with the data recovery process.
If an external hard drive fails or fails, careful attention is required.If you download or scan your own data recovery software and the data is overwritten, or if the platters that record the data inside your hard disk are slightly damaged, it will not be restored.A hard disk is a delicate device and one of the consumables.If the failure condition deteriorates, the data will disappear and the recovery itself may become difficult.If you want to try what you can do or think you can do something about it, you should give priority to stopping first.If you really want to recover by yourself, consult a professional data recovery service provider before proceeding, so you don′t have to regret it.
