What is a Network HDD (NAS)?
NAS refers to devices that can connect directly from multiple devices (such as personal computers, tablets, and smartphones) and share data and files over the network.The official name is Network Attached Storage, a network hard drive that is called NAS after its initials.
·Application of NAS
NAS such as TeraStation, LinkStation, and LANDISK is widely used by companies, schools, families and individuals to share and back up personal computer data.NAS transfers data over the network, allowing you to store, share and read data from multiple devices at the same time without having to connect directly to a personal computer, such as a portable external HDD, for easy access to data.
Data Recovery and Data Failure
Data recovery refers to the rescue and recovery of data from a shared folder in the event of equipment failure due to problems such as NAS not booting or NAS not being accessible, or accidental deletion of files or folders in the shared folder.
A data failure is a condition in which data cannot be read or written properly due to problems with recording media such as NAS or HDD.
Types and Causes of NAS Data Recovery
NAS data recovery problems are caused primarily by one or both of the following two failures:
logical disturbance
physical failure
1. Logical impairment
A logical failure in a NAS is a failure caused by a human error program, such as a corruption of recorded data or file systems, or a virus infection, although the equipment itself or the hard drive has not failed.
·Examples of the causes of logical failures in the NAS
Incorrectly erased data or shared files / Overwrite data on old NAS / Formatted data on multiple NASs / Initialized file index information disappeared / Unplugged or damaged file system or program files / Incorrectly deleted or overwritten/partitioned / damaged folder
2. Physical failure
A physical failure on the NAS is a failure caused by a physical or mechanical failure of the recording media and a damaged part.It is often caused by drops, shocks, vibrations, submergence of equipment, power outages, and aging.
If you suspect that your NAS is experiencing a physical failure, you should be careful because you often end up in an irreversible situation by simply turning it on or rebooting.If the data you keep is important, you should consult a specialized data recovery and repair company.
·Examples of causes of physical failure of NAS
NAS body, HDD, SSD failure, internal parts, board damage, HDD damage, power failure, lightning damage, aging deterioration, static electricity, overturning, vibration, moving, etc., NAS accidentally plugged in different cable, shorted, abnormal sound, thermal runaway, red light, etc.
Five solutions to recover data from the NAS: What you want to do now?
In the event that the NAS fails to start, cannot access shared folders, or accidentally erases files, the following 5 actions should be taken first.
From checking the NAS itself, such as cables and lamps on and off,
Checking for Error Messages and Codes
check backup functionality
check the trash can function
stop using the NAS
1. From checking the NAS body such as cable and lamp on/flashing, etc.
It is also important to check if the cable is stuck firmly and if there are any problems with the power supply when symptoms such as the NAS does not start or does not work.There are many cases where the cable is disconnected or coming off after moving or relocating.Also, in the case of NAS, when the data is inaccessible and other symptoms occur, the color of the body lamp is turned on or blinking red or orange instead of blue, green or white, so that abnormalities and conditions can be identified.If you have any trouble, check the color and blinking condition of the lamp.
*Some models have INFO/ERROR lamps, function lamps, AC adapter lamps, LINK/ACT lamps, etc. in addition to power lamps.
2. Check for error messages and codes
If you use a NAS such as TeraStation, LinkStation, or LANDISK, you can check the error message or error code to understand the status of the NAS.You may see multiple error messages and codes, so be careful not to miss them.In the case of the model displayed on the liquid crystal part of the main unit, you can switch between error messages and error codes by pressing the button next to it, so check if there are several abnormalities and take notes.Depending on the error message or error code, the solution will vary.
3. Check backup functionality
When using a NAS, it is often configured to regularly back up data to an external hard drive or other NAS.Not only when a problem occurs, but also check if the settings and data are properly backed up on a daily basis.If the backup settings are correct, you may be able to recover the data immediately from the backup area in the event of problems such as erasing the data by mistake or erasing folders or files.
4. Check the trash can function
Depending on the type of NAS, some models have trash can functionality.If the trash can function is installed and the settings are enabled, it can be recovered immediately if data loss occurs due to human errors such as accidental deletion, and the problem can be solved.
5. Discontinue NAS
If you have any symptoms or problems with your NAS, stop using the device.Keeping the NAS powered on without turning it off, repeatedly turning it off and rebooting, creating new files and folders, etc. can be dangerous to proceed with the seriousness of the condition and overwrite the data.In addition to increasing the difficulty of recovery, recovery itself can become difficult, so if you want to recover data quickly and cheaply, stop using the device.
Learn how NAS can recover data on its own
Below are some data recovery and restoration methods that you can try when your NAS has symptoms.
Check NAS model number, number of hard drives, RAID configuration
Disconnect the Hard Drive from the NAS
Find and download NAS-enabled recovery software
Connect HDD directly to PC
follow the screen of the recovery software
Recovery operation completed
1. Check NAS model number, number of hard drives, RAID configuration
The model number and model name of the NAS are listed in the case (outer case).Depending on the number of hard drives and the RAID configuration (level), we will start by checking.
·Examples of NAS model numbers and models
Buffalo NAS: LS-210D, LS-410D, LS720DN, LS411DX, LS-HGL, LS-VL, LS-YL, LS-WVL, LS-QVL, LS500, LS200 series, TS3220DN, TS3420DN, TS3420DN, TS5200D, TS6400RN, TS5210DN, TS3410D, TS5410DN series, etc.
IODATA NAS: HDL-A, HDL-C, HDL-S, HDL-CES, HDL-FM, etc.
·Examples of RAID types (levels)
If your NAS has more than one hard drive, check the RAID type (level).
RAID Examples: RAID 0 (Striping), RAID 1 (Mirroring), RAID 5, RAID 6, RAID 01, RAID 10, RAID 2, RAID 3, RAID 4, RAID 50, etc.
2. Disconnect the Hard Drive from the NAS
To recover data from the NAS, the internal hard drive must be removed from the chassis and prepared to look like an external hard drive using a SATA or USB conversion cable.Hard drives in NAS are often RAID-built, and in the event of trouble, malfunction, or failure, simply removing the hard drive from the chassis and attempting to put it back in place often leads to a RAID rebuild, resulting in data loss and difficulty in recovery.If you don′t want to fail or if your data is important, you should prioritize consulting a professional data recovery company before removing the hard drive.
*There are many cases where the manufacturer′s warranty does not cover the hard drive just by removing the hard drive from the case, so you need to be careful.
3. Locate and download NAS-enabled recovery software
There are a lot of recovery software and you need to find the right software for your operating system and RAID configuration.
Supported OS Examples: Windows 11, 10, 8, 7, XP, Vista/Mac OS X 10.6 to 10.15/Linux
Examples of supported media: flash memory such as external HDD, SSD, NAS, RAID, SD card, USB memory, etc.
RAID Configuration Example: RAID 0, RAID 1, RAID 5, RAID 6
Additional items to check: Does it support encrypted NAS?
暗号In order to recover encrypted data, deep expertise and advanced technical capabilities are also essential.There are also software that supports encryption, but in many cases, it is difficult to recover even if you use the software, and if you want to save money, or if you want to solve the problem quickly, you should consider consulting a professional data recovery company.
·How to check if the NAS is encrypted
NAS from Buffalo: NAS Navigator→ Administration Screen
IODATA NAS: MagicalFinder→ Management Screen
·Examples of NAS-enabled recovery software
EaseUS Data Recovery Wizard / NAS-RESUCE Series / Recovery Angel / Recoverit etc.
4. Connect HDD directly to PC
If you want to recover your NAS data using software, you will most likely need to disconnect the internal hard drive from the housing, cable it directly to your computer, and then use the software.If the hard drive is not recognized on the Windows disk management screen when connected to the computer, it is presumed that there is a physical failure, and the act of using the software itself is a serious task.If you suspect a physical failure, you should consult a professional data recovery company on the spot without using software.
NAS When connecting the hard drive taken from the NAS to the PC, ′Do you want to format it?′US>You may see an error message saying ′You must format it′, but be careful not to press ′Yes′ in a hurry.If you format it, all the data inside will be erased.
L When booting to Linux, you should be careful because executing commands such as ′fsck′ and ′xfs repair′ may change the data and file structure.
5. Follow the screen of the recovery software.
Once the software has been installed and the hard drive is connected to the computer, it is time to actually open the software program and take steps to recover data from the NAS.
·Example flow of NAS data recovery using software
①Select a location to save the file
②Search and scan partitions
③Press buttons such as Select and Restore Files
④review recovered data
復旧 If it can be recovered, you can expect to be able to access the data you want to recover by clicking on the automatically loaded drive or partition.
ネットワーク If the recovery software is available over the network, you will need to view the NAS′s remote access port and record the remote configuration.Change your settings by checking Control Panel → Terminal and SMAP → Enable SSH Service.Once the IP and port are automatically detected, enter your username and password to connect, and run a scan.
ソフト If the NAS you want to recover is not automatically detected on the software screen, press the button such as ′Manual connection′.
NAS Recovery software is not available if the hard drive in the NAS is mechanically or physically out of order.If you use it, it will cause serious conditions and promote data overwriting, so don′t try the software when you suspect aging or make noise.
6. Restoration work completed
If you can confirm that lost files and deleted folders have been recovered on the NAS, you will be able to complete.
復旧 Even if you use the restoration software, the restoration of the files you want is limited or only a part of them has been restored, and it is often restored in a damaged state. If you don′t want to fail or if data is important, don′t try it.
ハードディスク If you scan when recording media such as hard disks are about to break, the equipment will often be completely damaged.Let′s be careful.
*If you use the recovery software easily to do something by yourself, you may end up in an unrecoverable situation if you don′t use the software quickly and cheaply, so if you′re worried or data is important, you should consult a professional recovery company before proceeding.
Example of symptoms requiring NAS data recovery
There are various symptoms that require data recovery on the NAS.Since there is a risk of data loss in the event of the following problems, careful action is required.
NAS will not boot and will not power on
NAS inaccessible/unconnected
Unable to access shared folder and view data
Data in the shared folder has been deleted or deleted by mistake
RAID Collapse Occurred
Error codes or messages beginning in EM mode or I/O or E are displayed.
The NAS lamp is flashing red.
Internal HDD or SSD is broken
The NAS itself is out of order.
Data was not backed up
1. NAS will not boot · NAS will not power on
If the NAS such as TeraStation, LinkStation, and LANDISK does not start or power up, it may be possible that (1) the housing itself or the button has failed (2) the recording media such as HDD and SSD in the NAS has failed (3) the power cable has been damaged and the connection has failed.③Reseating and reseating the cable may improve the problem in the case of , but do not try any more if you have tried once and have not resolved it.In most cases, if the NAS does not boot, it is often caused by a physical failure of the recording media, and the condition may become serious just by turning on and off the power and restarting it repeatedly.
2. NAS cannot be accessed or connected
NAS is bootable, has a lamp, can hear operating sound, can′t access the NAS over the network even though it′s powered on, and when it can′t connect, it′s not the NAS itself, but storage side failures such as hard disks and SSDs, and firmware problems.If you can′t access the NAS, if you can′t connect, the data you have saved is important, if it′s gone, or if you think it might interfere with your work, turn off the power and don′t deteriorate your condition.If you continue to energize or proceed recklessly, you will not be able to retrieve the data and it will be difficult to recover.Even if the power is turned off and restarted without knowing it well, the situation may worsen to an irreversible extent.
3. Unable to access shared folder · Unable to view data
Even if the NAS is ready to boot and you can see folders on the network, there are many cases where you can′t access the shared folder that you were supposed to put in when you click on it, you can′t connect, the file won′t open, and you can′t see the data inside.If shared folders in the NAS are inaccessible, it is assumed that the hard disk or SSD is experiencing a logical or physical failure, or both failures, as well as file and data corruption.If you have trouble accessing shared folders, connecting to them, and so on, continue to work to see if you can do anything about it.·Continue to power up the device.·It is very dangerous to turn off the power and restart it many times.Not only does recovery become more difficult, but data recovery itself can become more difficult.First of all, let′s turn off the power and try not to get worse.
4. Data in the shared folder has been deleted/deleted by mistake
If you delete the data stored on your computer, it will go into the trash can, so if you respond quickly, it will not be difficult to recover, but if you delete or delete the data shared by NAS, it will usually disappear without entering the trash can.Data stored on NAS is often shared and often important.If data in shared folders is deleted, it can cause serious business disruption.In the unlikely event that the data is deleted, deleted, or formatted, the top priority is to stop using the NAS itself.If you keep using it, such as continuing to operate it or creating new data, the data will be overwritten more and more.The difficulty level of restoration increases, and the condition may deteriorate to a situation where restoration cannot be done again.If you notice that you have erased the data in your NAS, consider leaving it to a professional data recovery provider.
5. RAID Collapse Occurred
NAS builds RAID using multiple internal hard disks, SSDs, and other storage, which can cause RAID to collapse (RAID is a technology that recognizes multiple storage as a single drive).Raid corruption causes problems such as data read, write, and access.This is a particularly important situation where data is often lost in the event of a RAID collapse.For those who want to safely retrieve data from NAS or recover quickly and cheaply, it is also a good symptom to leave it to a professional.
6. Error codes and messages beginning in EM mode, I/O and E are displayed.
When a NAS such as TeraStation or LinkStation is in EM mode (standby mode/recovery mode), it may cause firmware damage, abnormalities, storage failures such as hard disk, NAS failure, board failure, etc.When entering EM mode, the NAS is often experiencing serious failures and should be careful.If you don′t want to lose your data, first turn off the NAS so that it doesn′t get worse.In addition to EM mode, in the event of NAS problems such as TerStation or LinkStation, the contents of error codes and messages starting with E or I can be used to determine the condition and cause of the NAS failure.If something goes wrong, let′s calmly check the contents and give priority to consulting a professional restoration company as soon as possible.
7. The NAS lamp is flashing red.
In the event of a failure or failure, many NASs can be identified by the color of the lamp.You need to be careful when the lamp is flashing red or orange.It often indicates that the NAS is broken, disk failure, RAID corruption, and so on, which requires careful attention.
8. Internal HDD or SSD is broken
Shared folders and files are inaccessible, NAS does not boot, error codes and messages are displayed, lamps flashing red, and so on, but these are often caused by hard disk or SSD failures.All data is stored on internal storage, which can lead to data loss if the storage fails or is corrupted.If you experience any symptoms or problems with your NAS, think that your internal storage is broken and act carefully.In the event of a hard disk or SSD failure, the condition often becomes critical immediately just by turning it on and off repeatedly, or by continuing to power it up.If your data is important, turn off your NAS and contact a professional recovery provider.
9. The NAS itself is out of order.
Even if the case is broken, the NAS will not be available.While replacing only the case may solve the problem, RAID reconstruction (rebuild) is likely to occur when the disk is removed from the NAS and replaced with another NAS, and if the hard disk is about to break, RAID reconstruction can worsen or completely break.In addition, if the order of the disks is wrong, the program and system information will be corrupted, and the data will be overwritten, making it difficult to recover.It is difficult to determine whether the NAS itself is broken or whether the disk or parts are broken by individuals, so if you have any difficulties or concerns, consult a professional data recovery company before proceeding with the operation and work.In the event of trouble, not only the case, but also the internal disks and internal parts are often damaged at the same time.
US>10. Data was not backed up
Many of you may be using NAS to back up your important data.However, there are many situations where the storage that is building RAID is broken and you have not been able to get backup in the middle.If one hard disk that is building RAID is broken, the other hard disk will fail in the same way, and overconfidence in RAID capabilities is dangerous.If you notice that the hard disk in your NAS has failed to back up your data, turn it off and try to keep your storage from deteriorating.The situation may become serious by continuing to energize, turning off or restarting the power.
RA If you run a NAS with RAID 0, if even one internal disk fails, you will not be able to read the data, so if you notice any abnormalities, you should give priority to consulting a professional.
Learn how NAS can recover and restore data
If the NAS experiences symptoms or failures, careful attention is required.You don′t need the data in the NAS and you just need to go back so that you can use the device.′·If you only want to repair the case, please consult with the ′′buying store or manufacturer′′.′If you want to recover or retrieve data from your NAS, choose a way to consult a data recovery company.
How to send it to a store or manufacturer′s repair shop
How to consult with a data recovery company
1. How to consult with the purchasing store or manufacturer
If you don′t need the data stored in the NAS and only want to repair the case, or if you think you just need to return the equipment to work, consider how to release the repair shop or manufacturer.When we ask the buyer or manufacturer to repair the equipment, the data on the disk is not guaranteed and is often initialized and disappeared.The purpose of the repair work is to replace and adjust parts for equipment that has failed or failed, unlike data recovery work.In many cases, even if the store or manufacturer provides recovery services, only logical failures are handled, and physical failures are not handled, and even if so, recovery is difficult after requesting them.Also, once it is released, it may take a long time to respond, and it may take a long time for the equipment to return, and during that time, the work may be delayed.If you want to solve the problem quickly or minimize the disruption to your business, first choose a method to consult a data recovery company.
2. How to consult with a data recovery company
For those who value the data stored on the NAS or want to get it out quickly and cheaply, choosing a way to consult a professional data recovery company can be a shortcut to solving the problem.There are various symptoms and problems with the NAS.If you proceed with the operation or work without your own knowledge, the condition may deteriorate to an irreversible extent.When you consult with a data recovery specialist, you can identify the cause, type of failure, and location of the symptom or trouble caused by advanced technical or technical expertise, and respond to logical and/or physical failures.However, there are many data recovery companies, and there are many problems such as not knowing which company to choose.If you are worried about choosing a company, check if it is a company that has ′original technology′ or ′AI technology.This is the standard for selecting highly skilled data recovery providers.Only when highly skilled companies perform recovery operations can they respond quickly and recover data at a low cost.If you request it, not every company can do the same restoration.There are also significant differences in technical capabilities and service content between data recovery providers.If you send it to a company that doesn′t have technical capabilities, it may be difficult to recover the data, take a long time, and the condition may deteriorate.Therefore, it is very important to choose the first company to request data recovery.
How to Choose a Data Recovery Agent
I often panic when the NAS has symptoms or failures.If you feel even a little uneasy or in trouble, consider starting with free consultation from a professional data recovery company.If you are worried about which company to consult with, you can check the following points to make your selection smoother.
See if they have advanced technology (either proprietary or AI technology)
Is recovery time and response speed fast?
Are restoration costs and fee plans listed on the website?
Does the organization work in a dedicated environment such as a clean room?
Is confidentiality of information and security management thorough?
Existence of restoration cases and actual results
It doesn′t matter where you ask for NAS data recovery.I searched and it was displayed above, so if you choose it without thinking too much about it, you may regret it.If your NAS contains important data, disappears or disappears, it will cause trouble to your clients if you can′t retrieve it, I want to fix it quickly, I want to use the data as it was, I′m concerned about recovery costs, I want to reduce recovery costs, etc.Advanced technology is proprietary and AI technology that uses advanced technology to recover data and repair equipment for NAS.Because of its advanced technology, it takes time to recover, deliver, and recover and repair data at a low price.It also has strict confidentiality and security management of information and a clean room.Whether you′re experiencing logical or physical failures such as NAS, RAID server, or hard disk, you can rest assured that you′ve been able to recover and repair data.
What to watch out for when you want to recover data from the NAS?
If you suspect a failure of the NAS itself or the internal disk, want to recover data in the event of a failure or failure, or want to retrieve data, be careful not to do the following:As a result of easy operation and work, it is possible that the conditions that could have been restored quickly and cheaply are often in a situation that cannot be recovered.
Continuing to energize ·Repeated power-on/reboot is not allowed
Removing the HDD from the NAS and connecting it directly to the PC is dangerous.
Avoid swapping or swapping internal hard drives
RAID rebuild (rebuild) is dangerous
Do not update the firmware or reinstall the operating system.
It is dangerous to carry out individual disassembly and repair work.
In the unlikely event that the operation or work has been carried out,
1. Continuing to energize · Repeated power-on/reboot is not allowed
In the event of a NAS problem or failure, the best solution is to turn off the equipment and make sure the situation does not worsen.Even if the device is energized while the cable is connected, the condition deteriorates and the data is often overwritten.First of all, it is important to unplug the cable so that the current does not pass.If you experience some symptoms such as NAS not starting, error code displayed, lamp flashing red, and shared folder inaccessible, you may think about turning off or restarting the power.However, turning off or rebooting power is one of the most stressful activities on the hard disk and internal components.In particular, if a hard disk containing data fails or is damaged, repeated power-on and reboots will cause scratches and grooves on the disk-like parts called platters where the data is stored, cause RAID controller malfunction.As a result of simple operations, it is often impossible to recover quickly and cheaply without it.If you have any concerns or concerns, consult a professional data recovery company before proceeding.There is no mistake.
2. It is dangerous to take the HDD out of the NAS and connect it directly to the PC.
The hard disk in the NAS has RAID, so even if you take it out and connect it to your computer alone, you won′t be able to see the data inside or access files and folders.In addition, taking out a disk and connecting it to a PC can cause data overwriting and data corruption.You may experience new failures or receive error messages such as フォーマットMust be formatted する.Taking out the hard disk that had been configured for RAID and connecting it to the PC itself is risky, and only the disadvantages stand out.If you really want to remove the disk from the case, consult a professional data recovery company before proceeding.
3. Avoid replacing or reordering internal hard drives
Storage, such as the hard disk in the NAS, is RAID built on multiple disks, so replacing or reordering disks can disrupt the regularity of stored data and result in corruption.If you continue to use it in that state, the data will remain corrupted and will be overwritten more and more, which may increase the difficulty level of data recovery and make it difficult to recover itself.When I try to replace it, I often mistake the location of the disk or I don′t know.Replacing a hard disk is one of the risky activities.In addition, if a hard disk fails, a RAID rebuild (rebuild) is often automatically performed, and you need to be careful.If you′re in trouble or in trouble, give priority to consulting a professional data recovery and repair company before proceeding.
4. RAID rebuild (rebuild) is dangerous
RAID rebuild (rebuild) refers to restoring and reconstructing data from another non-faulty disk if one of the disks that is building RAID, such as NAS, fails.However, RAID rebuild (rebuild) is one of the most risky practices.Rebuilds often worsen disk conditions, rebuilds themselves fail, and rebuilds often lead to irreversible situations.In addition, most NAS disks were manufactured at the same time, and if one fails, the other disks are almost broken.As a result of rebuilding, the number of hard disk failures is often increased, and rebuilding itself is not easy, so don′t force yourself to proceed if you feel any trouble or anxiety.
5. Do not update the firmware or reinstall the operating system.
When a TeraStation or LinkStation is in EM mode or the NAS is in RAID corruption mode, firmware updates are unlikely to solve the problem, and updates can often cause data to be overwritten or initialized, so it is recommended not to.You may be prompted to update the firmware or reinstall the operating system when the NAS does not start or start, but in the event of an error or malfunction, you should turn off the equipment and consult a professional data recovery company.If you proceed with the operation and work easily, it may not only increase the difficulty level of restoration, but also lead to the difficulty of restoration itself.
6. It is dangerous to carry out the disassembly and repair work individually.
You may want to find out the cause if something goes wrong, such as NAS not starting or data not being accessible.However, you should not tear down the NAS or hard disk to check for damage or perform personal repairs.In order to recover and repair data by disassembly, these four are essential: (1) a dedicated environment such as a clean room; (2) advanced technical capabilities; (3) deep expertise; (4) procurement of compatible parts.By any chance, if you break it down by yourself, the condition will become serious, and if you could recover quickly and cheaply, the difficulty level of recovery will increase, and the restoration itself will become difficult.Just like a specialist doctor doing human surgery in an operating room, repairing a NAS or hard disk or recovering data can only be successful if a specialist works in a specialized location.If you are using NAS and you experience problems, leave it to a technologically advanced data recovery company.That way, data recovery is definitely faster and cheaper.
7. In the unlikely event that the operation or work has been carried out,
Avoid scanning data recovery software, updating firmware, reinstalling operating systems, or rebuilding RAID in the event of a NAS failure, but in the unlikely event of a failure, stop and turn off the equipment immediately.It is very dangerous to proceed with the operation and work in order to do something by yourself.It often leads to unexpected results such as overwriting the data and increasing the difficulty level of recovery.Immediately after a failure, they were able to recover quickly and cheaply, but they are often unable to recover because of their own operations and operations.In the unlikely event that you have proceeded with the operation or work, or if you feel uneasy or have trouble in the middle, you should consult a professional data recovery company.
NAS Manufacturer List
NAS is manufactured and sold by various manufacturers.All NAS manufacturers have problems and problems all of a.k.a. problem.If you want to recover data quickly, cheaply and securely, or don′t want to fail, you should consult a professional data recovery company.

What is a Network HDD (NAS)?
NAS refers to devices that can connect directly from multiple devices (such as personal computers, tablets, and smartphones) and share data and files over the network.The official name is Network Attached Storage, a network hard drive that is called NAS after its initials.
·Application of NAS
NAS such as TeraStation, LinkStation, and LANDISK is widely used by companies, schools, families and individuals to share and back up personal computer data.NAS transfers data over the network, allowing you to store, share and read data from multiple devices at the same time without having to connect directly to a personal computer, such as a portable external HDD, for easy access to data.
Data Recovery and Data Failure
Data recovery refers to the rescue and recovery of data from a shared folder in the event of equipment failure due to problems such as NAS not booting or NAS not being accessible, or accidental deletion of files or folders in the shared folder.
A data failure is a condition in which data cannot be read or written properly due to problems with recording media such as NAS or HDD.
Types and Causes of NAS Data Recovery
NAS data recovery problems are caused primarily by one or both of the following two failures:
logical disturbance
physical failure
1. Logical impairment
A logical failure in a NAS is a failure caused by a human error program, such as a corruption of recorded data or file systems, or a virus infection, although the equipment itself or the hard drive has not failed.
·Examples of the causes of logical failures in the NAS
Incorrectly erased data or shared files / Overwrite data on old NAS / Formatted data on multiple NASs / Initialized file index information disappeared / Unplugged or damaged file system or program files / Incorrectly deleted or overwritten/partitioned / damaged folder
2. Physical failure
A physical failure on the NAS is a failure caused by a physical or mechanical failure of the recording media and a damaged part.It is often caused by drops, shocks, vibrations, submergence of equipment, power outages, and aging.
If you suspect that your NAS is experiencing a physical failure, you should be careful because you often end up in an irreversible situation by simply turning it on or rebooting.If the data you keep is important, you should consult a specialized data recovery and repair company.
·Examples of causes of physical failure of NAS
NAS body, HDD, SSD failure, internal parts, board damage, HDD damage, power failure, lightning damage, aging deterioration, static electricity, overturning, vibration, moving, etc., NAS accidentally plugged in different cable, shorted, abnormal sound, thermal runaway, red light, etc.
Five solutions to recover data from the NAS: What you want to do now?
In the event that the NAS fails to start, cannot access shared folders, or accidentally erases files, the following 5 actions should be taken first.
From checking the NAS itself, such as cables and lamps on and off,
Checking for Error Messages and Codes
check backup functionality
check the trash can function
stop using the NAS
1. From checking the NAS body such as cable and lamp on/flashing, etc.
It is also important to check if the cable is stuck firmly and if there are any problems with the power supply when symptoms such as the NAS does not start or does not work.There are many cases where the cable is disconnected or coming off after moving or relocating.Also, in the case of NAS, when the data is inaccessible and other symptoms occur, the color of the body lamp is turned on or blinking red or orange instead of blue, green or white, so that abnormalities and conditions can be identified.If you have any trouble, check the color and blinking condition of the lamp.
*Some models have INFO/ERROR lamps, function lamps, AC adapter lamps, LINK/ACT lamps, etc. in addition to power lamps.
2. Check for error messages and codes
If you use a NAS such as TeraStation, LinkStation, or LANDISK, you can check the error message or error code to understand the status of the NAS.You may see multiple error messages and codes, so be careful not to miss them.In the case of the model displayed on the liquid crystal part of the main unit, you can switch between error messages and error codes by pressing the button next to it, so check if there are several abnormalities and take notes.Depending on the error message or error code, the solution will vary.
3. Check backup functionality
When using a NAS, it is often configured to regularly back up data to an external hard drive or other NAS.Not only when a problem occurs, but also check if the settings and data are properly backed up on a daily basis.If the backup settings are correct, you may be able to recover the data immediately from the backup area in the event of problems such as erasing the data by mistake or erasing folders or files.
4. Check the trash can function
Depending on the type of NAS, some models have trash can functionality.If the trash can function is installed and the settings are enabled, it can be recovered immediately if data loss occurs due to human errors such as accidental deletion, and the problem can be solved.
5. Discontinue NAS
If you have any symptoms or problems with your NAS, stop using the device.Keeping the NAS powered on without turning it off, repeatedly turning it off and rebooting, creating new files and folders, etc. can be dangerous to proceed with the seriousness of the condition and overwrite the data.In addition to increasing the difficulty of recovery, recovery itself can become difficult, so if you want to recover data quickly and cheaply, stop using the device.
Learn how NAS can recover data on its own
Below are some data recovery and restoration methods that you can try when your NAS has symptoms.
Check NAS model number, number of hard drives, RAID configuration
Disconnect the Hard Drive from the NAS
Find and download NAS-enabled recovery software
Connect HDD directly to PC
follow the screen of the recovery software
Recovery operation completed
1. Check NAS model number, number of hard drives, RAID configuration
The model number and model name of the NAS are listed in the case (outer case).Depending on the number of hard drives and the RAID configuration (level), we will start by checking.
·Examples of NAS model numbers and models
Buffalo NAS: LS-210D, LS-410D, LS720DN, LS411DX, LS-HGL, LS-VL, LS-YL, LS-WVL, LS-QVL, LS500, LS200 series, TS3220DN, TS3420DN, TS3420DN, TS5200D, TS6400RN, TS5210DN, TS3410D, TS5410DN series, etc.
IODATA NAS: HDL-A, HDL-C, HDL-S, HDL-CES, HDL-FM, etc.
·Examples of RAID types (levels)
If your NAS has more than one hard drive, check the RAID type (level).
RAID Examples: RAID 0 (Striping), RAID 1 (Mirroring), RAID 5, RAID 6, RAID 01, RAID 10, RAID 2, RAID 3, RAID 4, RAID 50, etc.
2. Disconnect the Hard Drive from the NAS
To recover data from the NAS, the internal hard drive must be removed from the chassis and prepared to look like an external hard drive using a SATA or USB conversion cable.Hard drives in NAS are often RAID-built, and in the event of trouble, malfunction, or failure, simply removing the hard drive from the chassis and attempting to put it back in place often leads to a RAID rebuild, resulting in data loss and difficulty in recovery.If you don′t want to fail or if your data is important, you should prioritize consulting a professional data recovery company before removing the hard drive.
*There are many cases where the manufacturer′s warranty does not cover the hard drive just by removing the hard drive from the case, so you need to be careful.
3. Locate and download NAS-enabled recovery software
There are a lot of recovery software and you need to find the right software for your operating system and RAID configuration.
Supported OS Examples: Windows 11, 10, 8, 7, XP, Vista/Mac OS X 10.6 to 10.15/Linux
Examples of supported media: flash memory such as external HDD, SSD, NAS, RAID, SD card, USB memory, etc.
RAID Configuration Example: RAID 0, RAID 1, RAID 5, RAID 6
Additional items to check: Does it support encrypted NAS?
暗号In order to recover encrypted data, deep expertise and advanced technical capabilities are also essential.There are also software that supports encryption, but in many cases, it is difficult to recover even if you use the software, and if you want to save money, or if you want to solve the problem quickly, you should consider consulting a professional data recovery company.
·How to check if the NAS is encrypted
NAS from Buffalo: NAS Navigator→ Administration Screen
IODATA NAS: MagicalFinder→ Management Screen
·Examples of NAS-enabled recovery software
EaseUS Data Recovery Wizard / NAS-RESUCE Series / Recovery Angel / Recoverit etc.
4. Connect HDD directly to PC
If you want to recover your NAS data using software, you will most likely need to disconnect the internal hard drive from the housing, cable it directly to your computer, and then use the software.If the hard drive is not recognized on the Windows disk management screen when connected to the computer, it is presumed that there is a physical failure, and the act of using the software itself is a serious task.If you suspect a physical failure, you should consult a professional data recovery company on the spot without using software.
NAS When connecting the hard drive taken from the NAS to the PC, ′Do you want to format it?′US>You may see an error message saying ′You must format it′, but be careful not to press ′Yes′ in a hurry.If you format it, all the data inside will be erased.
L When booting to Linux, you should be careful because executing commands such as ′fsck′ and ′xfs repair′ may change the data and file structure.
5. Follow the screen of the recovery software.
Once the software has been installed and the hard drive is connected to the computer, it is time to actually open the software program and take steps to recover data from the NAS.
·Example flow of NAS data recovery using software
①Select a location to save the file
②Search and scan partitions
③Press buttons such as Select and Restore Files
④review recovered data
復旧 If it can be recovered, you can expect to be able to access the data you want to recover by clicking on the automatically loaded drive or partition.
ネットワーク If the recovery software is available over the network, you will need to view the NAS′s remote access port and record the remote configuration.Change your settings by checking Control Panel → Terminal and SMAP → Enable SSH Service.Once the IP and port are automatically detected, enter your username and password to connect, and run a scan.
ソフト If the NAS you want to recover is not automatically detected on the software screen, press the button such as ′Manual connection′.
NAS Recovery software is not available if the hard drive in the NAS is mechanically or physically out of order.If you use it, it will cause serious conditions and promote data overwriting, so don′t try the software when you suspect aging or make noise.
6. Restoration work completed
If you can confirm that lost files and deleted folders have been recovered on the NAS, you will be able to complete.
復旧 Even if you use the restoration software, the restoration of the files you want is limited or only a part of them has been restored, and it is often restored in a damaged state. If you don′t want to fail or if data is important, don′t try it.
ハードディスク If you scan when recording media such as hard disks are about to break, the equipment will often be completely damaged.Let′s be careful.
*If you use the recovery software easily to do something by yourself, you may end up in an unrecoverable situation if you don′t use the software quickly and cheaply, so if you′re worried or data is important, you should consult a professional recovery company before proceeding.
Example of symptoms requiring NAS data recovery
There are various symptoms that require data recovery on the NAS.Since there is a risk of data loss in the event of the following problems, careful action is required.
NAS will not boot and will not power on
NAS inaccessible/unconnected
Unable to access shared folder and view data
Data in the shared folder has been deleted or deleted by mistake
RAID Collapse Occurred
Error codes or messages beginning in EM mode or I/O or E are displayed.
The NAS lamp is flashing red.
Internal HDD or SSD is broken
The NAS itself is out of order.
Data was not backed up
1. NAS will not boot · NAS will not power on
If the NAS such as TeraStation, LinkStation, and LANDISK does not start or power up, it may be possible that (1) the housing itself or the button has failed (2) the recording media such as HDD and SSD in the NAS has failed (3) the power cable has been damaged and the connection has failed.③Reseating and reseating the cable may improve the problem in the case of , but do not try any more if you have tried once and have not resolved it.In most cases, if the NAS does not boot, it is often caused by a physical failure of the recording media, and the condition may become serious just by turning on and off the power and restarting it repeatedly.
2. NAS cannot be accessed or connected
NAS is bootable, has a lamp, can hear operating sound, can′t access the NAS over the network even though it′s powered on, and when it can′t connect, it′s not the NAS itself, but storage side failures such as hard disks and SSDs, and firmware problems.If you can′t access the NAS, if you can′t connect, the data you have saved is important, if it′s gone, or if you think it might interfere with your work, turn off the power and don′t deteriorate your condition.If you continue to energize or proceed recklessly, you will not be able to retrieve the data and it will be difficult to recover.Even if the power is turned off and restarted without knowing it well, the situation may worsen to an irreversible extent.
3. Unable to access shared folder · Unable to view data
Even if the NAS is ready to boot and you can see folders on the network, there are many cases where you can′t access the shared folder that you were supposed to put in when you click on it, you can′t connect, the file won′t open, and you can′t see the data inside.If shared folders in the NAS are inaccessible, it is assumed that the hard disk or SSD is experiencing a logical or physical failure, or both failures, as well as file and data corruption.If you have trouble accessing shared folders, connecting to them, and so on, continue to work to see if you can do anything about it.·Continue to power up the device.·It is very dangerous to turn off the power and restart it many times.Not only does recovery become more difficult, but data recovery itself can become more difficult.First of all, let′s turn off the power and try not to get worse.
4. Data in the shared folder has been deleted/deleted by mistake
If you delete the data stored on your computer, it will go into the trash can, so if you respond quickly, it will not be difficult to recover, but if you delete or delete the data shared by NAS, it will usually disappear without entering the trash can.Data stored on NAS is often shared and often important.If data in shared folders is deleted, it can cause serious business disruption.In the unlikely event that the data is deleted, deleted, or formatted, the top priority is to stop using the NAS itself.If you keep using it, such as continuing to operate it or creating new data, the data will be overwritten more and more.The difficulty level of restoration increases, and the condition may deteriorate to a situation where restoration cannot be done again.If you notice that you have erased the data in your NAS, consider leaving it to a professional data recovery provider.
5. RAID Collapse Occurred
NAS builds RAID using multiple internal hard disks, SSDs, and other storage, which can cause RAID to collapse (RAID is a technology that recognizes multiple storage as a single drive).Raid corruption causes problems such as data read, write, and access.This is a particularly important situation where data is often lost in the event of a RAID collapse.For those who want to safely retrieve data from NAS or recover quickly and cheaply, it is also a good symptom to leave it to a professional.
6. Error codes and messages beginning in EM mode, I/O and E are displayed.
When a NAS such as TeraStation or LinkStation is in EM mode (standby mode/recovery mode), it may cause firmware damage, abnormalities, storage failures such as hard disk, NAS failure, board failure, etc.When entering EM mode, the NAS is often experiencing serious failures and should be careful.If you don′t want to lose your data, first turn off the NAS so that it doesn′t get worse.In addition to EM mode, in the event of NAS problems such as TerStation or LinkStation, the contents of error codes and messages starting with E or I can be used to determine the condition and cause of the NAS failure.If something goes wrong, let′s calmly check the contents and give priority to consulting a professional restoration company as soon as possible.
7. The NAS lamp is flashing red.
In the event of a failure or failure, many NASs can be identified by the color of the lamp.You need to be careful when the lamp is flashing red or orange.It often indicates that the NAS is broken, disk failure, RAID corruption, and so on, which requires careful attention.
8. Internal HDD or SSD is broken
Shared folders and files are inaccessible, NAS does not boot, error codes and messages are displayed, lamps flashing red, and so on, but these are often caused by hard disk or SSD failures.All data is stored on internal storage, which can lead to data loss if the storage fails or is corrupted.If you experience any symptoms or problems with your NAS, think that your internal storage is broken and act carefully.In the event of a hard disk or SSD failure, the condition often becomes critical immediately just by turning it on and off repeatedly, or by continuing to power it up.If your data is important, turn off your NAS and contact a professional recovery provider.
9. The NAS itself is out of order.
Even if the case is broken, the NAS will not be available.While replacing only the case may solve the problem, RAID reconstruction (rebuild) is likely to occur when the disk is removed from the NAS and replaced with another NAS, and if the hard disk is about to break, RAID reconstruction can worsen or completely break.In addition, if the order of the disks is wrong, the program and system information will be corrupted, and the data will be overwritten, making it difficult to recover.It is difficult to determine whether the NAS itself is broken or whether the disk or parts are broken by individuals, so if you have any difficulties or concerns, consult a professional data recovery company before proceeding with the operation and work.In the event of trouble, not only the case, but also the internal disks and internal parts are often damaged at the same time.
US>10. Data was not backed up
Many of you may be using NAS to back up your important data.However, there are many situations where the storage that is building RAID is broken and you have not been able to get backup in the middle.If one hard disk that is building RAID is broken, the other hard disk will fail in the same way, and overconfidence in RAID capabilities is dangerous.If you notice that the hard disk in your NAS has failed to back up your data, turn it off and try to keep your storage from deteriorating.The situation may become serious by continuing to energize, turning off or restarting the power.
RA If you run a NAS with RAID 0, if even one internal disk fails, you will not be able to read the data, so if you notice any abnormalities, you should give priority to consulting a professional.
Learn how NAS can recover and restore data
If the NAS experiences symptoms or failures, careful attention is required.You don′t need the data in the NAS and you just need to go back so that you can use the device.′·If you only want to repair the case, please consult with the ′′buying store or manufacturer′′.′If you want to recover or retrieve data from your NAS, choose a way to consult a data recovery company.
How to send it to a store or manufacturer′s repair shop
How to consult with a data recovery company
1. How to consult with the purchasing store or manufacturer
If you don′t need the data stored in the NAS and only want to repair the case, or if you think you just need to return the equipment to work, consider how to release the repair shop or manufacturer.When we ask the buyer or manufacturer to repair the equipment, the data on the disk is not guaranteed and is often initialized and disappeared.The purpose of the repair work is to replace and adjust parts for equipment that has failed or failed, unlike data recovery work.In many cases, even if the store or manufacturer provides recovery services, only logical failures are handled, and physical failures are not handled, and even if so, recovery is difficult after requesting them.Also, once it is released, it may take a long time to respond, and it may take a long time for the equipment to return, and during that time, the work may be delayed.If you want to solve the problem quickly or minimize the disruption to your business, first choose a method to consult a data recovery company.
2. How to consult with a data recovery company
For those who value the data stored on the NAS or want to get it out quickly and cheaply, choosing a way to consult a professional data recovery company can be a shortcut to solving the problem.There are various symptoms and problems with the NAS.If you proceed with the operation or work without your own knowledge, the condition may deteriorate to an irreversible extent.When you consult with a data recovery specialist, you can identify the cause, type of failure, and location of the symptom or trouble caused by advanced technical or technical expertise, and respond to logical and/or physical failures.However, there are many data recovery companies, and there are many problems such as not knowing which company to choose.If you are worried about choosing a company, check if it is a company that has ′original technology′ or ′AI technology.This is the standard for selecting highly skilled data recovery providers.Only when highly skilled companies perform recovery operations can they respond quickly and recover data at a low cost.If you request it, not every company can do the same restoration.There are also significant differences in technical capabilities and service content between data recovery providers.If you send it to a company that doesn′t have technical capabilities, it may be difficult to recover the data, take a long time, and the condition may deteriorate.Therefore, it is very important to choose the first company to request data recovery.
How to Choose a Data Recovery Agent
I often panic when the NAS has symptoms or failures.If you feel even a little uneasy or in trouble, consider starting with free consultation from a professional data recovery company.If you are worried about which company to consult with, you can check the following points to make your selection smoother.
See if they have advanced technology (either proprietary or AI technology)
Is recovery time and response speed fast?
Are restoration costs and fee plans listed on the website?
Does the organization work in a dedicated environment such as a clean room?
Is confidentiality of information and security management thorough?
Existence of restoration cases and actual results
It doesn′t matter where you ask for NAS data recovery.I searched and it was displayed above, so if you choose it without thinking too much about it, you may regret it.If your NAS contains important data, disappears or disappears, it will cause trouble to your clients if you can′t retrieve it, I want to fix it quickly, I want to use the data as it was, I′m concerned about recovery costs, I want to reduce recovery costs, etc.Advanced technology is proprietary and AI technology that uses advanced technology to recover data and repair equipment for NAS.Because of its advanced technology, it takes time to recover, deliver, and recover and repair data at a low price.It also has strict confidentiality and security management of information and a clean room.Whether you′re experiencing logical or physical failures such as NAS, RAID server, or hard disk, you can rest assured that you′ve been able to recover and repair data.
What to watch out for when you want to recover data from the NAS?
If you suspect a failure of the NAS itself or the internal disk, want to recover data in the event of a failure or failure, or want to retrieve data, be careful not to do the following:As a result of easy operation and work, it is possible that the conditions that could have been restored quickly and cheaply are often in a situation that cannot be recovered.
Continuing to energize ·Repeated power-on/reboot is not allowed
Removing the HDD from the NAS and connecting it directly to the PC is dangerous.
Avoid swapping or swapping internal hard drives
RAID rebuild (rebuild) is dangerous
Do not update the firmware or reinstall the operating system.
It is dangerous to carry out individual disassembly and repair work.
In the unlikely event that the operation or work has been carried out,
1. Continuing to energize · Repeated power-on/reboot is not allowed
In the event of a NAS problem or failure, the best solution is to turn off the equipment and make sure the situation does not worsen.Even if the device is energized while the cable is connected, the condition deteriorates and the data is often overwritten.First of all, it is important to unplug the cable so that the current does not pass.If you experience some symptoms such as NAS not starting, error code displayed, lamp flashing red, and shared folder inaccessible, you may think about turning off or restarting the power.However, turning off or rebooting power is one of the most stressful activities on the hard disk and internal components.In particular, if a hard disk containing data fails or is damaged, repeated power-on and reboots will cause scratches and grooves on the disk-like parts called platters where the data is stored, cause RAID controller malfunction.As a result of simple operations, it is often impossible to recover quickly and cheaply without it.If you have any concerns or concerns, consult a professional data recovery company before proceeding.There is no mistake.
2. It is dangerous to take the HDD out of the NAS and connect it directly to the PC.
The hard disk in the NAS has RAID, so even if you take it out and connect it to your computer alone, you won′t be able to see the data inside or access files and folders.In addition, taking out a disk and connecting it to a PC can cause data overwriting and data corruption.You may experience new failures or receive error messages such as フォーマットMust be formatted する.Taking out the hard disk that had been configured for RAID and connecting it to the PC itself is risky, and only the disadvantages stand out.If you really want to remove the disk from the case, consult a professional data recovery company before proceeding.
3. Avoid replacing or reordering internal hard drives
Storage, such as the hard disk in the NAS, is RAID built on multiple disks, so replacing or reordering disks can disrupt the regularity of stored data and result in corruption.If you continue to use it in that state, the data will remain corrupted and will be overwritten more and more, which may increase the difficulty level of data recovery and make it difficult to recover itself.When I try to replace it, I often mistake the location of the disk or I don′t know.Replacing a hard disk is one of the risky activities.In addition, if a hard disk fails, a RAID rebuild (rebuild) is often automatically performed, and you need to be careful.If you′re in trouble or in trouble, give priority to consulting a professional data recovery and repair company before proceeding.
4. RAID rebuild (rebuild) is dangerous
RAID rebuild (rebuild) refers to restoring and reconstructing data from another non-faulty disk if one of the disks that is building RAID, such as NAS, fails.However, RAID rebuild (rebuild) is one of the most risky practices.Rebuilds often worsen disk conditions, rebuilds themselves fail, and rebuilds often lead to irreversible situations.In addition, most NAS disks were manufactured at the same time, and if one fails, the other disks are almost broken.As a result of rebuilding, the number of hard disk failures is often increased, and rebuilding itself is not easy, so don′t force yourself to proceed if you feel any trouble or anxiety.
5. Do not update the firmware or reinstall the operating system.
When a TeraStation or LinkStation is in EM mode or the NAS is in RAID corruption mode, firmware updates are unlikely to solve the problem, and updates can often cause data to be overwritten or initialized, so it is recommended not to.You may be prompted to update the firmware or reinstall the operating system when the NAS does not start or start, but in the event of an error or malfunction, you should turn off the equipment and consult a professional data recovery company.If you proceed with the operation and work easily, it may not only increase the difficulty level of restoration, but also lead to the difficulty of restoration itself.
6. It is dangerous to carry out the disassembly and repair work individually.
You may want to find out the cause if something goes wrong, such as NAS not starting or data not being accessible.However, you should not tear down the NAS or hard disk to check for damage or perform personal repairs.In order to recover and repair data by disassembly, these four are essential: (1) a dedicated environment such as a clean room; (2) advanced technical capabilities; (3) deep expertise; (4) procurement of compatible parts.By any chance, if you break it down by yourself, the condition will become serious, and if you could recover quickly and cheaply, the difficulty level of recovery will increase, and the restoration itself will become difficult.Just like a specialist doctor doing human surgery in an operating room, repairing a NAS or hard disk or recovering data can only be successful if a specialist works in a specialized location.If you are using NAS and you experience problems, leave it to a technologically advanced data recovery company.That way, data recovery is definitely faster and cheaper.
7. In the unlikely event that the operation or work has been carried out,
Avoid scanning data recovery software, updating firmware, reinstalling operating systems, or rebuilding RAID in the event of a NAS failure, but in the unlikely event of a failure, stop and turn off the equipment immediately.It is very dangerous to proceed with the operation and work in order to do something by yourself.It often leads to unexpected results such as overwriting the data and increasing the difficulty level of recovery.Immediately after a failure, they were able to recover quickly and cheaply, but they are often unable to recover because of their own operations and operations.In the unlikely event that you have proceeded with the operation or work, or if you feel uneasy or have trouble in the middle, you should consult a professional data recovery company.
NAS Manufacturer List
NAS is manufactured and sold by various manufacturers.All NAS manufacturers have problems and problems all of a.k.a. problem.If you want to recover data quickly, cheaply and securely, or don′t want to fail, you should consult a professional data recovery company.
