What is a Hard Drive?
A hard disk is a storage device used to store data, officially known as a hard disk drive (HDD).Hard disks are built into personal computers, network HDDs (NAS) and servers, and are often used as external hard disks to store data.
Types of Hard Disk Errors
′A hard disk problem has been detected.′
′Back up the files on the disk immediately to avoid data loss, and then contact your computer manufacturer to see if the disk needs to be repaired or replaced.′
′Checking for disk errors.It may take more than an hour to complete.′
′A disk read error occurred Press Ctrl+Alt+Del to restart′

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.
Example of a Hard Disk Error
If there is an error on your computer, don′t panic and take action.Error messages may appear continuously every 5 or 10 minutes.If the hard disk fails, you may experience the following symptoms or failures, so be careful.
Hard disk drive failure
Data in the hard drive (photos/video/word/excel/documents/programs/files/folders/applications, etc.) will disappear/data will be lost
Windows System File Corruption
The computer cannot boot to the operating system.
Computer freezes
Computer operation becomes heavy, takes time, and stops responding
No access to files or folders
If an error occurs, start the backup job
If you encounter an error while using your hard disk, start by backing up your data if you can.This is because the data may disappear or become corrupted.You can also initialize as a solution to the error, but be sure to copy and back up the data before initializing, as initialization will erase all data stored in the factory restore of the hard disk.
·Manual backup
Manually copying to recording media such as external hard disks/SSDs or USB memory/CD/DVDs is the easiest backup method.By selecting and storing only the data you need, you can reduce the amount of data you need, and you can choose the amount of data you need.
·Automatic backup
Sometimes external hard disks and personal computers come with software that automatically backs up your data.Regular backup processing reduces the risk of data loss due to sudden failures and errors.
·Back up using software
Backup Software Example
OS with free soft backup coverage
All stored data including partitions, including free miniTool Partition Wizard Windows XP/Windows Vista
/ Windows 7 / Windows 8 / Windows 10
·Back up regularly
Keep your data backed up periodically other than when you see errors.
What to watch out for before checking for errors on your hard disk
Hard disk errors include physical errors (hardware problems) and logical errors (software problems).Use the SMART feature to determine if your hard drive is experiencing a physical error.
Using the SMART Feature to Check the State of the Hard Disk
One way to check for physical errors among hard disk errors is to use the SMART feature.SMART functionality refers to Self-Monitoring, Analysis and Reporting Technology/Self-Monitoring Analysis and Reporting Technology as SMART= Smart.This SMART feature allows you to check the health and life of your hard disk numerically.US>Soft tools are required to verify SMART information.
·Examples of tools for using the SMART function
Tool Example for Verifying SMART Features Available OS for SMART Features
CrystalDiskInfo/HDD Health/Hard Drive Inspector/Active SMART/From HDD to SSD/HDD-SCAN/HDDlife/HDD SMART Analyzer/HD Tune·Mam′s SMART Reader/Hard Disk Smart Checker/PC-Doctor for Windows/SpeedFan/SMART Reporter/Apple Macintosh TechTool/Windows/Apple/Windows/Windows/Apple/Windows/Windows/Windows/Windows/Windows/Windows/Windows/Windows/Windows 8
If you are experiencing physical errors on your hard disk, try using the SMART feature to determine what errors you are experiencing.
What Causes Hard Drive Errors?
When you get an error such as ′A hard disk problem has been detected,′ the following causes may be considered.
The hard drive is physically damaged or damaged
viral attacks and infections
US>System Errors
wrong or improper operation
Bad sectors or internal write errors
1. Physical failure or damage to the hard drive.
A hard disk is one of the precision instruments.It may break down due to aging or shock.In the event of a physical failure or damage, the condition may deteriorate due to repeated power-on and reboots.You should be extra careful when making noise.Let′s turn off the power and consult a professional restoration company as soon as possible.
↓Here′s how to resolve the noise from your hard drive.

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?
2. Virus attacks and infections
There are a variety of anti-virus software, but you need to be careful because computer viruses are frequently attacked.If your computer is infected with a virus, it will damage your system and cause damage.If you are infected with a virus, you will also receive an error indicating that there is a problem with the disk.
US>3. System Errors
A variety of system errors can be possible, such as fragmented files/registry errors or excessive startup behavior (program that starts when Windows starts).in the event of a system error
·I accidentally delete important system files
·Destroy or shut down the OS system
·Corrupt system files
Because it may lead to , we recommend that you back up your critical data when a system error occurs and you say ′Hard Disk Problem Detected′.
4. Incorrect or inappropriate operation
Wrong/wrong or improper operation can cause serious damage or problems to the operating system.
5. Bad sectors and internal write errors
Physical or logical errors on hard drives are prone to bad sectors.A bad sector can damage the data stored.An error message also appears when a bad sector occurs.In addition, bad sectors can occur on any computer, NAS internal hard drive or external hard drive.

External hard drives may suddenly become unrecognized or inaccessible, and may fail due to aging.This section describes how to recover and restore data, along with the causes and failures of external hard drives.
What are the most common ′bad sectors′ of hard disk errors?
A bad sector is a sector (area) that cannot be read or written to recording media such as hard disk or flash memory, and only a limited portion of the sector is experiencing physical failure.When recording data on a hard disk, it is read and written by using magnetic force on the recording surface, but the deterioration of the magnetic force will result in bad sectors (unavailable sectors).It is said that this is the most common cause of a physical failure and failure of the hard disk.Hard disks read and write over a long period of time, making them prone to bad sectors.Windows error occurs when booting the computer with a bad sector.In this case, start your computer in Safe Mode and back up your data.Then proceed to Hard Disk Error Repair.
HARD DISK ERROR REPAIRING METHOD
There are several ways to repair a hard disk error:
How to Use the Error Checking Feature on a Windows 10 Computer
Repair Methods and Procedures for Bad Sectors
How to Simultaneously Check and Repair Hard Disks
Execute command prompt ′chkdsk′ when logical errors are considered
How to deal with suspected viral infections
Hard disk initialization
Run the System File Checker (SFC)
Perform a surface test (bad sector inspection of the disk surface)
Use HDAT2, the hard disk diagnostic tool software
Use Windows Installation Media to Check and Repair Errors
1. How to use the error checking function on a Windows 10 computer
When you see a hard disk error message on a Windows 10 computer, check the following order:
①Control Panel → Security and Maintenance → Open Maintenance
②Check Drive Status
③If there is no problem with the condition of the drive, the message ′All drives are working properly′ will appear.
This Windows error check is a drive error check, not a hard disk error check, so if this action does not stop the error on your computer, you will need to do something else.
2. Repair methods and procedures for defective sectors
①Open a folder at the bottom of the screen or on the desktop → Select PC from the list on the left when you open the folder
②Devices and Drives → Select Hard Disk with Error → Right-click → Open Properties
③Properties → Select Tools → Click Check in Error Check Items → Scan for bad sectors and check items to recover → Press Start → Scan begins and remediation begins.
If you can′t repair a hard disk error by trying this method, consider stopping using it and consulting a recovery specialist at an early stage.
3.How to simultaneously check and repair hard disk errors
If a hard drive fails, there is a way to simultaneously check for errors and repair the hard drive.
·To run on a Windows 10 PC
①Start, close all applications you are using/close the application
②Start → Open in order of computer
③Right-click the drive you want to repair → Properties → Tool → Select Error Check
④The operation method differs between the first time and the second time.
④- 1 First Time
Check Disk → Check both the items ′Automatically Repair File System Errors′ and ′Scan and Recover Bad Sectors′ in the check disk options and press Start
④- After the second time
Check Disk → Check the items in the disk options, check Scan for Bad Sectors, and press Start.
This will allow you to check for errors.When a hard drive fails, a pop-up often appears at the same time that prompts you to repair the drive.Let′s follow the instructions.
·To repair a hard disk error on an iOS Mac computer
Use Disk Utility → First Aid to check and repair hard disk errors on a Mac computer.
①Click ′Lanchpad′ on the Mac Dock → Other → Open Disk Utility
②Disk Utility → Select a disk from the left column
③Select Disk → Icon appears at the top of the screen → Select First Aid from the icons → Press Validate Disk
④Verification begins → Check the operation of the computer during verification or a pop-up appears → Press ′Verify Disk′ again
This flow completes the error check.If you see the error again, try this method to check the error and repair the disk.
3. How to perform error checking and remediation from disk management properties
①Right-click the Windows Start button
②Click Manage Disks
③Right-click the drive you want to check for errors → Click Properties
④Select Tools Tab → Error Check → Check
⑤Select ′Repair This Drive′ if an error is detected
⑥′No need to scan this drive′ when no errors are detected
⑦′After the scan, ′′Your drive has been successfully scanned′′ appears.′→ Press Close to complete.
4. Execute command prompt ′chkdsk′ when logical errors are considered
File system error = If you are experiencing a logical error, you can check the status quo using ′1. How to use Windows error checking′.However, logical errors often have a negative impact on the entire hard disk, so try running ′chkdsk′ using a command prompt (CMD) as well as Windows error checking.
Note: Avoid using ′chkdsk′ when you see CRC errors (cyclic redundancy check errors) as the hard disk itself is often physically faulty.′This is because ′′chkdsk′′ is read/write for a long time after execution, so the condition may deteriorate due to the heavy burden on the recording medium.′In addition, ′chkdsk′ detects and corrects logical errors in the specified drive, so you must run ′chkdsk′ on each drive separately if you are partitioning the hard disk into multiple partitions or recognizing it as a different drive.
·How to use the command prompt (CMD) and chkdsk
Type cmd in the Windows 10 search box, or press Windows and R keys at the same time → type cmd in the Run section → press enter → right-click the command prompt → select Run as Administrator.
·Type of command
Commands and Options Details
chkdsk (Drive letter of interest:) /r
Scan the free space as well (specified the ′/r′ option.A file system is registered so as to avoid when a defective sector is detected.Commands that are more likely to complete in one check than in other commands because ′chkdsk/r′ even checks for bad sectors (physical error checks).After finding a bad sector, proceed to recover readable information.
chkdsk (drive letter:) /f
(Specify the ′/f′ option) Commands that work only on NTFS file systems.Repair disk errors.
Example: In the case of chkdskg:/f, check the error in the volume (G:) and repair the error found.(G
: can be replaced by another drive letter.)
Valid command for both chkdsk (drive letter: )/v NTFS partition/FAT32 partition.FAT/FAT32...Displays the name and full path of all files on disk, NTFS...Displays cleanup messages, etc.
Only chkdsk (drive letter:) /c NTFS volumes are enabled.Skip the circular reference check for the folder structure.
Only chkdsk (drive letter:) / NTFS is enabled.Check of index entries is suppressed and executed.Can reduce chkdsk execution time.
chkdsk (drive letter:) /L: resize size log file (change to specified value) Show current value if no size is specified.
Only chkdsk (drive letter:) /b NTFS is enabled.Re-evaluate a cluster with a bad volume.When this option is specified, the options ′/r′ and ′/f′ are also specified.Force unmount the chkdsk (drive letter:) /x drive.
5. How to deal with suspected viral infections
Back up your data first.Download antivirus software when you get a backup.Run software to scan → remove viruses.If you download spyware, programs, or malware, you risk being infected with the virus.If your computer is suspected to be infected with a virus, use the software to remove the virus before proceeding to correct the error.
6. Hard disk initialization
′A hard drive problem has been detected′ may appear when an error occurs, or the hard drive itself may appear due to a physical failure or a write error inside the hard drive.There is an initialization method to repair the error.
·Initialize on Windows 10 PC
①Press Windows and X keys → List menu
②Select Disk Management from the Menu List
③Click on the hard disk with the error indication → Initialize the disk
·Initialize on Windows 7 PC
①Press Windows Key or Start Button → Click Control Panel
②Control Panel → Select System and Security
③Administrative Tools → Select hard disk partition creation and formatting
④Click on the hard disk with the error indication → Initialize the disk
Hard disk errors can be fixed by initializing and errors that cannot be fixed, but initialization is a process in which all stored data disappears, so if data is important, stop using it and consult a specialized recovery company first.
7. Run the System File Checker (SFC)
If you are using a Windows 10 computer, try using the System File Checker (SFC).The SFC can check for errors in the system files and deal with many of the problems that are occurring, and is expected to repair the errors.
·How to use the System File Checker (SFC)
①Right-click on the Start Menu → Execute a command prompt with administrator privileges
②Enter ′sfc/scannow′ and wait for confirmation.
Note: Verification is time consuming.Do not close the window until it is finished.
Use this command to scan all system files (including protected files) and replace any corrupted or corrupted files with Windows 10 backup copies to repair them.If this command is not expected to work, proceed to the next method.
8. Conduct a surface test (bad sector inspection of the disk surface)
If a bad sector results in a ′hard disk problem detected′ error display, you can use the ′MiniTool Partition Wizard′ to check for errors and scan for bad sectors.
·How to perform a surface test using the MiniTool Partition Wizard
①Launch the Free MiniTool Partition Wizard Partition Manager → Select a target hard drive within the main screen → Check Disk menu → Click Surface Test
②Click Start Now → Disk Test will run.
Note: Surface testing may take several minutes.Do not close the window until it is finished.
③If there is an error, the red mark appears.If there are no read errors, the green mark will be displayed.
④This flow completes the hard disk error checking with the surface test.
The MiniTool Partition Wizard can be checked, but the error cannot be corrected, so proceed to the next step to resolve the issue.
9. Use the hard disk diagnostic tool software HDAT2
The advantage of using HDAT2 is that it can detect not only bad sectors but also unstable sectors before they become bad sectors, and sectors that are slow to read and read.If you scan with this software HDAT2, it will be reflected in the SMART information if a bad sector is detected during the scan.HDAT2 may appear to increase the number of bad sectors in the SMART information, but the number also includes those sectors before they become unstable or bad, so that′s a normal number.If a bad sector is detected using HDAT2, it can be repaired as it is.We will check the error and repair the defective sector at the same time.The disadvantage of using HDAT2 is that it often takes time to work, which puts a lot of strain on the hard disk.Therefore, if a physical failure occurs on the hard disk, the condition will deteriorate.It is often better to refrain from using software when the stored data is important.
US>10. Use Windows Installation Media to Check and Repair Errors
If Windows does not start, you can use the Windows installation media to check and repair hard disk errors.
①Insert Windows 10 installation media into your computer
②BIOS → Change boot order → Change settings from Windows 10 installation media to Boot
③Select the language, time and currency format, keyboard or input method, and keyboard type items to install → Click Next
④Click Repair Your Computer
⑤Click Troubleshooting
⑥Advanced Options → Select Command Prompt
When the command prompt appears, look at the procedure ′4. Run the command prompt ′′chkdsk′′ if you think of a logical error.′
Summary - If you are still in trouble, don′t do anything unnecessary and go to the restoration company
Let′s start by checking one by one when a hard disk fails, such as ′A hard disk problem has been detected.′It′s also important to stop working if you′re worried while checking, or if you′re storing important data on your hard disk.If you want to recover quickly and cheaply or don′t want to fail, let′s prioritize consulting a professional data recovery company.When an error is displayed, it is often a sign of a serious failure in the hard disk.If an error occurs on the computer screen, contact a specialized recovery company to resolve the problem quickly and prevent data from disappearing.Advanced technology can handle a variety of hard drive problems and reduce recovery costs.Why don′t you start with a free consultation?

④Select Tools Tab → Error Check → Check
⑤Select ′Repair This Drive′ if an error is detected
⑥′No need to scan this drive′ when no errors are detected
⑦′After the scan, ′′Your drive has been successfully scanned′′ appears.′→ Press Close to complete.
4. Execute command prompt ′chkdsk′ when logical errors are considered
File system error = If you are experiencing a logical error, you can check the status quo using ′1. How to use Windows error checking′.However, logical errors often have a negative impact on the entire hard disk, so try running ′chkdsk′ using a command prompt (CMD) as well as Windows error checking.
Note: Avoid using ′chkdsk′ when you see CRC errors (cyclic redundancy check errors) as the hard disk itself is often physically faulty.′This is because ′′chkdsk′′ is read/write for a long time after execution, so the condition may deteriorate due to the heavy burden on the recording medium.′In addition, ′chkdsk′ detects and corrects logical errors in the specified drive, so you must run ′chkdsk′ on each drive separately if you are partitioning the hard disk into multiple partitions or recognizing it as a different drive.
·How to use the command prompt (CMD) and chkdsk
Type cmd in the Windows 10 search box, or press Windows and R keys at the same time → type cmd in the Run section → press enter → right-click the command prompt → select Run as Administrator.
·Type of command
Commands and Options Details
chkdsk (Drive letter of interest:) /r
Scan the free space as well (specified the ′/r′ option.A file system is registered so as to avoid when a defective sector is detected.Commands that are more likely to complete in one check than in other commands because ′chkdsk/r′ even checks for bad sectors (physical error checks).After finding a bad sector, proceed to recover readable information.
chkdsk (drive letter:) /f
(Specify the ′/f′ option) Commands that work only on NTFS file systems.Repair disk errors.
Example: In the case of chkdskg:/f, check the error in the volume (G:) and repair the error found.(G
: can be replaced by another drive letter.)
Valid command for both chkdsk (drive letter: )/v NTFS partition/FAT32 partition.FAT/FAT32...Displays the name and full path of all files on disk, NTFS...Displays cleanup messages, etc.
Only chkdsk (drive letter:) /c NTFS volumes are enabled.Skip the circular reference check for the folder structure.
Only chkdsk (drive letter:) / NTFS is enabled.Check of index entries is suppressed and executed.Can reduce chkdsk execution time.
chkdsk (drive letter:) /L: resize size log file (change to specified value) Show current value if no size is specified.
Only chkdsk (drive letter:) /b NTFS is enabled.Re-evaluate a cluster with a bad volume.When this option is specified, the options ′/r′ and ′/f′ are also specified.Force unmount the chkdsk (drive letter:) /x drive.
5. How to deal with suspected viral infections
Back up your data first.Download antivirus software when you get a backup.Run software to scan → remove viruses.If you download spyware, programs, or malware, you risk being infected with the virus.If your computer is suspected to be infected with a virus, use the software to remove the virus before proceeding to correct the error.
6. Hard disk initialization
′A hard drive problem has been detected′ may appear when an error occurs, or the hard drive itself may appear due to a physical failure or a write error inside the hard drive.There is an initialization method to repair the error.
·Initialize on Windows 10 PC
①Press Windows and X keys → List menu
②Select Disk Management from the Menu List
③Click on the hard disk with the error indication → Initialize the disk
·Initialize on Windows 7 PC
①Press Windows Key or Start Button → Click Control Panel
②Control Panel → Select System and Security
③Administrative Tools → Select hard disk partition creation and formatting
④Click on the hard disk with the error indication → Initialize the disk
Hard disk errors can be fixed by initializing and errors that cannot be fixed, but initialization is a process in which all stored data disappears, so if data is important, stop using it and consult a specialized recovery company first.
7. Run the System File Checker (SFC)
If you are using a Windows 10 computer, try using the System File Checker (SFC).The SFC can check for errors in the system files and deal with many of the problems that are occurring, and is expected to repair the errors.
·How to use the System File Checker (SFC)
①Right-click on the Start Menu → Execute a command prompt with administrator privileges
②Enter ′sfc/scannow′ and wait for confirmation.
Note: Verification is time consuming.Do not close the window until it is finished.
Use this command to scan all system files (including protected files) and replace any corrupted or corrupted files with Windows 10 backup copies to repair them.If this command is not expected to work, proceed to the next method.
8. Conduct a surface test (bad sector inspection of the disk surface)
If a bad sector results in a ′hard disk problem detected′ error display, you can use the ′MiniTool Partition Wizard′ to check for errors and scan for bad sectors.
·How to perform a surface test using the MiniTool Partition Wizard
①Launch the Free MiniTool Partition Wizard Partition Manager → Select a target hard drive within the main screen → Check Disk menu → Click Surface Test
②Click Start Now → Disk Test will run.
Note: Surface testing may take several minutes.Do not close the window until it is finished.
③If there is an error, the red mark appears.If there are no read errors, the green mark will be displayed.
④This flow completes the hard disk error checking with the surface test.
The MiniTool Partition Wizard can be checked, but the error cannot be corrected, so proceed to the next step to resolve the issue.
9. Use the hard disk diagnostic tool software HDAT2
The advantage of using HDAT2 is that it can detect not only bad sectors but also unstable sectors before they become bad sectors, and sectors that are slow to read and read.If you scan with this software HDAT2, it will be reflected in the SMART information if a bad sector is detected during the scan.HDAT2 may appear to increase the number of bad sectors in the SMART information, but the number also includes those sectors before they become unstable or bad, so that′s a normal number.If a bad sector is detected using HDAT2, it can be repaired as it is.We will check the error and repair the defective sector at the same time.The disadvantage of using HDAT2 is that it often takes time to work, which puts a lot of strain on the hard disk.Therefore, if a physical failure occurs on the hard disk, the condition will deteriorate.It is often better to refrain from using software when the stored data is important.
US>10. Use Windows Installation Media to Check and Repair Errors
If Windows does not start, you can use the Windows installation media to check and repair hard disk errors.
①Insert Windows 10 installation media into your computer
②BIOS → Change boot order → Change settings from Windows 10 installation media to Boot
③Select the language, time and currency format, keyboard or input method, and keyboard type items to install → Click Next
④Click Repair Your Computer
⑤Click Troubleshooting
⑥Advanced Options → Select Command Prompt
When the command prompt appears, look at the procedure ′4. Run the command prompt ′′chkdsk′′ if you think of a logical error.′
Summary - If you are still in trouble, don′t do anything unnecessary and go to the restoration company
Let′s start by checking one by one when a hard disk fails, such as ′A hard disk problem has been detected.′It′s also important to stop working if you′re worried while checking, or if you′re storing important data on your hard disk.If you want to recover quickly and cheaply or don′t want to fail, let′s prioritize consulting a professional data recovery company.When an error is displayed, it is often a sign of a serious failure in the hard disk.If an error occurs on the computer screen, contact a specialized recovery company to resolve the problem quickly and prevent data from disappearing.Advanced technology can handle a variety of hard drive problems and reduce recovery costs.Why don′t you start with a free consultation?
