What is a Hard Drive?
A hard drive is a storage device or recording medium that is used to store data.The official name is Hard Disk Drive, which is called Hard Disk Drive.Hard drives are vulnerable to external factors such as shock and fever, and may fail due to daily use, environment, and aging.
HDD (Hard Drive) Type
Hard drives can be divided into three main types when connecting to a PC.
There are three types in total: those built into a PC, those used as external HDDs, and those built into a network HDD (NAS).
·Integrated HDD
An internal hard drive is a recording medium that is installed and integrated into a computer, such as a laptop or desktop computer, and is mainly stored in the operating system.In addition to the operating system, it also stores user-generated and installed data, which is an essential part of running a PC.
·External HDD
An external hard drive is a recording medium that uses USB or eSATA to connect to a personal computer and store data.External hard drives are typically stored in a case.External HDDs can be broadly divided into portable and stationary hard drives.Features of portable external HDDs include mainstream 2TB to 4TB capacity, smaller size, portable, USB powered, shock-resistant models, no need for dedicated power supplies, etc.Features of stationary models include large capacity such as 4TB and 6TB, large capacity, large size, portable, faster data transfer, cheaper than portable models with the same capacity, and better for PC backup.
·Network HDD (NAS)
Network HDD (NAS) is a recording medium that can be connected directly from multiple devices (smartphones such as Windows/Mac PC, Android/iPhone, and tablets such as iPad).The official name is Network Attached Storage, which is called NAS.It looks like an external hard drive, but the network hard drive (NAS) has components such as OS, CPU, and other PC components, and is more like a PC than an external hard drive.Network HDD (NAS) is a wired or wireless connection that allows multiple people to use and share data at the same time from a terminal connected to the same network.It is often used to store and share important data, and many network (HDDs) have a configuration called RAID, which is resistant to failure and other problems.

https://www.adte.jp/rec/hdd/post-748/
One way to store important data is to use a RAID configured device.There are different types of RAID, each operating and recovery methods.Learn how to recover and respond to RAID failures such as inaccessible, inaccessible, unable to connect, unable to enter shared folders, data disappeared, and errors.
Type of failure (what is a physical or logical failure of the hard drive)
There are two types of hard drive failures:
1. Physical failure
2. Logical impairment
1. What is a Physical Failure?
A physical failure is a failure caused by a physical breakdown of the hard drive/a failure of the hard drive itself.Physical failure can be caused by shock, vibration, fall, deterioration over time, power failure, lightning strike, submergence, thermal runaway, etc.
2. What is a Logical Failure?
Logical failure is a failure caused by a corruption of stored data or a programming problem, although the HDD itself has no problem or has not failed.Logical failures can be caused by file system corruption, program file corruption, deletion of folders, files, etc. due to malfunction, program corruption due to virus infection, initialization, formatting, and failure to remove hard drives safely from a PC.There may be an error message that prevents the computer from starting.
Hard Drive Failure Symptoms and Criteria
The following symptoms and errors may occur before or after a hard drive failure:It is better to avoid continuing to use it when this kind of trouble or phenomenon occurs.Be careful because repeated power-on, power-off, and reboots can worsen the condition and cause a complete failure.
Hard Drive Not Recognized/Connected/Accessible/Not Responding/Not Loading
No power
be making a noise
burnish
get an error message
Cannot access folders or files/application not open
·Hard drive does not recognize/connect/load
When the HDD is not recognized or loaded even when connected to a computer, it is estimated that the physical failure described above has occurred.If your data is important, try to stop using it and turn it off so that the condition does not change.
↓If you are having trouble with the hard drive not recognizing it, please refer to this as well.

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
·The noise is ringing
Turn off the computer immediately if you hear noise such as clattering, clattering, clattering, clattering, etc. when you start your computer.It is a sign that the hard drive is failing or is about to break.Noise is caused by parts coming into contact with each other inside the hard drive.
·Error message is displayed
If the hard drive fails, you may receive an error message when using your computer.If you see an error, don′t panic and check the message.If you do not respond appropriately and press the button appropriately, or if you operate it, the condition of the trouble may get worse.The error message is often a sign that the hard drive will fail, so be careful.

Have you ever been confused by an error on your computer while using a hard disk?If a hard disk fails, such as ′A hard disk problem has been detected,′ don′t panic and check one by one.This section describes how to repair an error message when using a hard disk or when an error is detected.
·Scent of burning
Be careful when the device smells burnt.There may be a short circuit in the base or chip inside the hard drive, or there may be a short circuit in the cord.It is important to turn off the power immediately when it smells.Be careful when you feel unusually hot after touching the computer.
Three ways to retrieve data from a failed hard drive
There are several ways to retrieve data from a suspected failed hard drive:
1. Move data to another PC
2. Use free software
3. Consultation with a data recovery specialist
1. Move data to another PC
The fastest way to deal with situations where the computer does not work or starts is to take the hard disk out of the computer that does not start and connect it to another computer that starts normally to recover the data.The hard drive must be removed from the computer to perform the operation.○ How to recover data by removing the hard drive from a non-booting PC
①work preparation
Conversion cable to connect HDD to another PC / + driver / another PC to boot normally
②Remove the Hard Drive from a Non-Booting Computer
Desktop computers can be easier to take out than laptops, but laptops can be difficult to take out hard drives because of the complexity of wiring.Decomposition of a personal computer may require specialized knowledge and skills.Also, there is a risk that if you break it down by yourself, you will be excluded from the manufacturer′s warranty, so if your data is important and your personal computer is important, don′t push yourself too hard and consult a specialized data recovery company.
③To eject a hard drive from a desktop computer
Turn off the computer → Unplug the wall → Unscrew and open the computer case → Remove the side panel → Remove the hard drive using a screwdriver as it is screwed to the case → Unplug the hard drive power and ATA cables for impact → Remove operation completed
④How do I remove a hard drive from my laptop?
Turn off the computer → Unplug the adapter → Disconnect the battery → Remove all screws that hold the hard drive if the hard drive is inside the back panel → Pull out the hard drive → Pull out the hard drive 取り出し Pull out the hard drive 完了 Remove the battery 背面 Remove the hard drive.
*Depending on the manufacturer and type of laptop, it may be difficult to take out the hard drive, or it may be necessary to take it apart. Therefore, if you feel a little uneasy or difficult to take it apart, please refrain from contacting a specialized restoration company.When decomposition is necessary, it is necessary to work in a specialized environment such as a clean room.
⑤Choose a USB Conversion Cable
Once the hard drive has been removed from the computer, try connecting it to a computer that can boot normally using a USB conversion cable.Hard drive connectivity standards include IDE and SATA.Choose a conversion cable to match your connection specifications.
·IDE connection
IDE is an older standard and is nicknamed ATA, ATAPI, and Parallel ATA.The IDE connection is different between desktop and laptop computers.Desktop computers have a 3.5′ IDE connection, while laptops have a 2.5′ IDE connection.As the shape is different, it is correct to choose a USB conversion cable that supports both 2.5′ and 3.5′ IDE.
·SATA connection
Currently, SATA is the main connection standard for hard drives.SATA connections are L-shaped.If you have an integrated SATA hard drive, use a SATA USB conversion cable.
·Standards other than IDE and SATA
There are many other standards besides IDE and SATA.SCSI and SAS used by servers such as NAS, as well as miniSATA and MicroSATA, which are the same but different shapes as SATA.Note that for hard drives configured with RAID on servers such as NAS, you cannot see the data inside even if you take it out and connect it to your computer alone.
⑥Connect to another PC using a USB conversion cable
Connect the hard drive to another computer that can boot normally using a USB conversion cable.If the hard drive appears on my computer, etc., it is a known sign.If the hard drive is not recognized or cannot be accessed, the hard drive may have failed.In that case, do not proceed further and contact the data recovery provider as soon as possible.
⑦extraction of data
If your hard drive is detected correctly on a different bootable computer, copy or migrate the data you need from your computer as you would with an external hard drive.When disk space is available, copying all of the data contained in it can help prevent forgetting to remove it or failing to migrate.With SSDs, you can retrieve data in the same way.
⑧Change the connection cable and try again
①If the problem persists after trying ~7, you can also change the connection cable.USB conversion cable is also compatible.Also, USB-powered cables can be unstable due to lack of power.It is smoother to select a USB conversion cable with a power adapter.
⑨Try USB 3.0/USB 3.1/USB 2.0 Specifications
Connecting with older USB 2.0 standards may be easier to recognize than connecting to the new USB 3.0/USB 3.1.
2. Use free software
There is a way to use free software for data recovery when the computer itself can start and operate even if the hard disk is unstable.Keep in mind that while using software is easy, there are risks.In the event of a problem with the hard drive itself, such as a physical failure, software use or installation may worsen the condition or overwrite progresses.It is also labor-intensive to find software that matches the symptoms among a number of software.There are many explanatory statements and manuals written only in English, so you may be worried.If data is important, consult a specialized recovery company before using free software.
·Examples of free software
Free software fee-based recovery software OS

3. Consultation with a data recovery specialist
There are many factors that can cause problems and failures of personal computers and HDDs, and it is often difficult to identify.Unfortunately, it is possible that the condition will deteriorate if you work or operate it yourself.In the event of trouble or failure, it would be better to consult a specialized data recovery company as soon as possible to resolve the problem.If you are worried about choosing a restoration company, you can find out if you have the technology by checking if you have AI technology.AI technology also reduces recovery costs.
What to do when a hard drive fails
If you suspect a hard drive failure, you should avoid the following.
1. Power cycle/reboot repeatedly
2. Continue to energize
3. Do not format
4. Decomposition and opening
1. Power cycle/reboot repeatedly
It is recommended to avoid turning off the power or rebooting repeatedly when symptoms such as instability or poor condition of the computer are occurring.If you do it when the condition is unstable or about to fail, the hard drive may be overloaded and deteriorated.
2. Continue to energize
If you continue to energize the hard drive while it is out of order, the internal parts will continue to malfunction and other unusual operations.As a result, the condition may deteriorate.The best way is to turn off the power when there is a problem.
3. Do not format
Do you want to format it?Be careful when you receive error messages such as .After formatting, the stored data disappears.If the data is important, don′t rush to press the button.
↓ Do you want to format it?Here′s how to resolve the error message.
AT DATA RECOVERY MEDIUM
It must be formatted.Here′s how to deal with errors!
https://www.adte.jp/rec/hdd/post-862/
When connecting an external hard disk, SD card, USB memory, etc. to a PC, the error ′Must be formatted′ or ′Do you want to format?′ may appear.Don′t panic if you can′t see the data stored on an external hard drive without opening the drive.If you see the error ′Must be formatted′, we will show you how to recover and resolve the data.
4. Decomposition and opening
In the event of a hard drive failure, it is necessary to dismantle, open, or replace parts, but it also requires expertise and technical ability to procure and replace parts, such as clean rooms.If you take it apart or open it by yourself, the manufacturer′s warranty may not be covered.In many cases, the situation gets worse even if you force yourself to work on it, so if data is important, you should prioritize consulting with a specialized recovery company rather than doing the restoration work on your own.
Summary - If you are still in trouble, don′t do anything unnecessary and go to the restoration company
When storing data from a computer, it is usually stored on an internal hard drive, but if you continue to use it when there is not much free space, your computer may become unstable.Keep in mind that data is backed up on an external hard drive or network hard drive (NAS) on a daily basis to prevent data loss.In the unlikely event that the hard drive fails, you should be careful as the situation may get worse if you push ahead with the work or operate it without reflecting on it.If data is important, consider consulting a specialized recovery company as soon as possible.Advanced technology can help you recover and repair data on your hard drive.Diagnosis and consultation are free, so why don′t you start by contacting them first?
