Regardless of your operating system (Windows XP, Windows 7, Windows 8), go to Computer (My Computer, This Computer), right-click on the drive you want to check, select " Properties".
In the properties window, go to the " tab Service" and click the " button Run check".
Check both boxes
Automatically fix system errors.
Scan and repair system sectors.
and press " Launch".
If you check the system volume (the disk on which the operating system is installed, usually drive C), you will see the message " Windows cannot verify the hard drive that is currently in use", click " Disk check schedule".
Then restart your computer/laptop; during boot, the process of checking and correcting errors on the disk will begin. It will last from several minutes to an hour (depending on the size of the partition and the physical characteristics of the hard drive). When finished, the operating system will boot.
Checking the hard drive using the chkdsk utility.
CHKDSK (short for check disk) is a standard application in the DOS and Microsoft Windows operating systems that checks a hard drive or floppy disk for file system errors (for example, the same sector is marked as belonging to two different files). CHKDSK can also fix file system errors it finds. (from Wikipedia)
In order to run the chkdsk utility, you need to run a command prompt with administrator rights, to do this:
IN Windows XP click - "Command line"
IN Windows 7 click "Start" - "All Programs" - "Accessories" "Command line" and select "Run as administrator".
IN Windows 8.1 right click on "Start" - "Command Prompt (Administrator)".
As a result, a command line console will open.
First of all, let's find out the syntax of the chkdsk utility:
CHKDSK [volume[[path]filename]] ]
Volume Specifies the mount point, volume name, or drive letter of the drive being checked, followed by a colon.
file name Files checked for fragmentation (FAT/FAT32 only).
/F Correcting disk errors.
/V For FAT/FAT32: output the full path and name of each file on the disk. For NTFS: display cleanup messages (if any).
/R Search for bad sectors and restore surviving contents (requires /F).
/L:size For NTFS only: Set the log file size (in KB). If a size is not specified, the current size value is displayed.
/X Pre-dismount the volume (if necessary). All open handles to this volume will be invalidated (requires /F).
/I NTFS only: Less strict checking of index entries.
/C NTFS only: skip checking for loops within folder structures.
/B NTFS only: Re-evaluate bad clusters on disk (requires /R)
The /I or /C options reduce Chkdsk execution time by skipping some volume checks.
Of all the command attributes, the two most often used to check a disk for errors are /f and /r. The final command looks like this:
chkdsk C:/F/R
With this command we will check partition C, correct errors on the disk and restore information from damaged sectors (if any).
After entering this command, you will be prompted to check the volume the next time the system reboots, click Y and a key Enter.
Now you need to reboot the system, when loading you will see a window prompting a check, do not click anything, just wait 10 seconds.
Checking for hard drive errors using Victoria.
The Victoria program is designed to check for errors on hard drives with IDE and Serial ATA interfaces. The program is a completely ready-made solution for a comprehensive, in-depth, and at the same time, the fastest possible assessment of the real technical condition of the HDD.
First of all, download the ISO image of the program from official website . Unzip the downloaded archive and burn it to a CD/DVD, as described in the article How to burn to CD/DVD . After this, boot from the burned disk, how to do this is described step by step in the article How to boot from a CD/DVD disk or USB flash drive .
After booting from the disk within 10 seconds, select the program for your device (Victoria for the computer will load by default).
The program interface will launch. Press the F2 key so that the program itself finds the disk; if this does not happen, you must do it manually. To do this, press the "P" key. The same will have to be done if the system has several hard drives and you need to select one of them. If you have hard drives with a SATA interface, then in the Select HDD port menu that appears, select - " Ext. PCI ATA/SATA". Move using the cursor keys "up", "down", and select using the "Enter" key.
Next, to check the disk surface, press the F4 key. In the HDD scan menu window: select the necessary scan parameters. By default, it is proposed to scan the entire disk from the beginning of "Start LBA: 0" to the end of "End LBA: 20971520". I recommend leaving these default values. The next menu item – I recommend leaving “Linear reading”, since it is intended for the fastest and most accurate diagnosis of the surface condition. In the fourth point, I recommend choosing the mode BB = Advanced REMAP since this mode checks the disk most efficiently and corrects errors on it without deleting information.
After this, a check for hard disk errors will start and bad areas will be corrected. This procedure can take from several tens of minutes to several hours. Depends on the volume and spindle speed.
When finished, remove the disc from the drive and restart the computer.

Often, users are forced to believe that the operating system (OS) system files are damaged, the reason being typical failures when performing basic operations and slow computer operation. It happens that loading an external IT product leads to a destructive change in the OS configuration. In these cases, checking the integrity of system files in Windows 10 helps.
Typically, the OS provides two software products SFC.exe and DISM.exe, and, in addition, the Repair-WindowsImage command for Windows PowerShell. The first ones check the integrity of the system components and automatically restore their identified defects. The second does this by using DISM.
Experts are confident that it is more advisable to use them one by one, since the lists of scanned files for these software tools differ from each other.
In continuation, we will consider several instructions for using the presented software. The described actions are safe, but you must remember that restoring system files is complex in nature and affects even those changes made by the user himself. In particular, installation of external resources and other OS conversions will be canceled.
Examine the integrity of the system and correct its elements using SFC
The sfc /scannow OS integrity scanning command is popular among experienced users. It automatically examines and eliminates defects in OS components.
SFC operates as an administrator, through the command line, which is opened by right-clicking on the Start menu. Next, enter sfc /scannow and press Enter.
These actions begin a scan of the OS, as a result of which the detected damage is corrected. If there are no errors, the user sees the message “Windows Resource Protection detected no integrity violations.” Another aspect of this study is irreparable damage. Part of the continuation of this article will be devoted to them.
The sfc /scanfile=”path_to_file” command allows you to check for errors in a specific system component.
The disadvantage of the software is that it does not eliminate defects in OS elements used during scanning. The problem is solved by running SFC via the command line in the OS recovery environment. This method is quite effective and involves performing several simple operations.
Integrity testing using SFC in an OS recovery environment
It does not take much time and does not require special skills. Launching in the OS recovery environment is performed in several ways:
- You need to go to “Settings” and select “Update and security”, “Recovery”, “Custom boot options” and “Restart now” one by one. A simpler method: in the lower right part of the OS login interface, click the “on” tab, after which, while holding “Shift”, you need to click “Reboot”.
- Another option is to boot from a pre-prepared OS recovery disk.
- Another alternative is an electronic medium with an OS distribution. In the installation program, after selecting the language, select “System Restore” in the lower left part.
When finished, you need to enter “Troubleshooting”, select “Advanced options” and click “Command Prompt” (using the first of the previously presented methods requires entering the system administrator password). The following is applied sequentially:
- diskpart
- list volume
Based on the results of running the specified commands, the user sees a list of volumes. It is recommended to remember their designations corresponding to the “System Reserved” drive and the OS partition, since sometimes they differ from those in Explorer.
sfc /scannow /offbootdir=F:\ /offwindir=C:\Windows (where F is the previously specified “System Reserved” drive, and C:\Windows is the path to the OS folder).
The described actions initiate an in-depth investigation of the system's integrity, during which the SFC command fixes all damaged components, without exception. Studying can take a long time. The underscore indicator blinks to indicate that the system is continuing to operate. When finished, the command line closes and the OS reboots in standard mode.
Scan and repair your system using DISM.exe
It happens that the SFC team cannot cope with some defects in system components. The IT product DISM.exe allows you to complete the restoration you have started. It scans and maintains the system, fixing even the most problematic components.
DISM.exe is used even when SFC does not detect OS integrity defects, but there is still reason to suspect that they exist.
First of all, right-click on the Start menu as an administrator to launch the Command Prompt. Then other commands are launched:
- dism /Online /Cleanup-Image /CheckHealth. It is used to generate information about the state of the OS and the presence of damage to its components. Does not initiate the study, scans earlier values of recorded parameters.
- dism /Online /Cleanup-Image /ScanHealth. Explores and verifies the integrity of the system components repository. Takes a long time, barely breaking the 20% mark.
- dism /Online /Cleanup-Image /RestoreHealth. Examines and automatically repairs the OS. It works slowly, interrupting at times.
In circumstances where system element store recovery is not performed, install.wim (esd) with Windows 10 ISO is used as the source of the patchable components. Another option is used for this:
dism /Online /Cleanup-Image /RestoreHealth /Source:wim:path_to_wim_file:1 /limitaccess
In some cases, “.wim is replaced by .esd.”
While using these commands, all operations performed are saved in a log, which is contained in Windows\Logs\CBS\CBS.log and Windows\Logs\DISM\dism.log. The DISM tool runs in the OS recovery environment in the same way as it does when running SFC.
This software tool is also implemented in Windows PowerShell as an administrator, using a set of Repair-WindowsImage commands. For example:
- Repair-WindowsImage -Online -ScanHealth. Looks for defects in system elements,
- Repair-WindowsImage -Online -RestoreHealth. Investigates and troubleshoots problems.
Apparently, restoring the integrity of the OS is a completely feasible task, the solution of which allows you to get rid of various problems with the system. In rare cases when the described tools do not help, you should use other publicly available algorithms. In particular, you should try to roll back the system to the previous Windows 10 restore point.
Some users are faced with the fact that SFC detects defects in system elements immediately after updating with a new OS build. Under these conditions, error correction is possible only with a new “clean” installation of the system image. Sometimes damage is detected in certain versions of video card software. In this case, the file opencl.dll is erroneous. It may not be worth taking any action at all in these circumstances.
Conclusion
The described methods for studying the integrity of the OS are simple and effective. The stages of their implementation are understandable to most of the user audience, including those who do not have special programming skills. However, to reinforce the material, videos that are publicly available on the Internet will be useful.
Nobody likes it when the usual customized Windows 10 starts to crash and freeze. Let's figure out what reasons this may be associated with, and learn how to identify and correct the problems that have arisen.
Checking Windows 10 for errors
There are two types of errors in the operation of computer devices:
- hardware - physical damage to the device’s hardware is to blame for their appearance;
- software - associated exclusively with the software component.
Let's figure out how to identify these failures and correct them using various means.
If hardware errors can be “cured” only by replacing or repairing the damaged part, then software failures can be corrected using special built-in or third-party utilities.
Diagnostics Windows 10 using SFC
SFC.exe is a system utility built into Windows 10, which is responsible for checking the integrity and functionality of system files. If any of them are damaged, the program automatically repairs them. SFC is not omnipotent: it is recommended to use it in conjunction with DISM, which will be discussed later. However, using this utility is practically the first thing to do in case of system failures.
For some (sometimes quite a long) time, the utility will check system files for integrity. After completion of the work, it will give the user the result.
SFC cannot repair some of the system files while Windows is running, because they are currently in use by the system. If the SFC check shows that there are problems, but it cannot solve them, the utility must be launched again, but not from the system, but from the Windows recovery tool.
You can open the Windows Recovery Tool in the following ways:
- go to “Start” - “Settings” - “Update and Security” - “Recovery” - “Special boot options” - “Restart now”;
The Update & Security item in Windows Settings allows you to access the special boot options menu
- select the "System Restore" option when booting from installation media (or from a recovery disk);
Click on the "System Restore" button when booting from installation media
- instead of the start button, click on a special button that allows you to enter recovery mode. It is available on some laptops, for example Lenovo. As a rule, such a button is located either next to the system start button or next to the charger connector.
Some laptops have a button that opens the recovery menu
From the recovery menu, do the following:
This time, the SFC utility will be able to repair all files, even those that are usually inaccessible to it.
Video: how to run the SFC utility
Scan and repair Windows 10 using DISM
DISM is another utility for recovering damaged files. Its scope of application is much wider than that of SFC. You can even use it to make system backups. DISM and SFC are responsible for different groups of system files, and using them together is more effective than using them individually.
Diagnostics and repair of system files using DISM are also carried out through the “Command Line”. How to enter it is described above. There are several options for using the command:
- dism /Online /Cleanup-Image /CheckHealth - no check is performed, the utility displays the latest saved data on the status of the files;
The command dism /Online /Cleanup-Image /CheckHealth shows what results the disk check gave last time
- dism /Online /Cleanup-Image /ScanHealth - checks the integrity of files without “fixing” the problems found;
The command dism /Online /Cleanup-Image /ScanHealth starts checking all system files through DISM without “repairing”
- dism /Online /Cleanup-Image /RestoreHealth - starts checking the integrity of files and then restoring damaged files.
Checking system files in DISM and then repairing damage is started with the command dism /Online /Cleanup-Image /RestoreHealth
Scanning and restoring files takes quite a long time. Also a completely normal feature of the DISM utility is the status bar freezing at 20%.
Video: how to check the integrity of Windows 10 using SFC and DISM
Checking the hard drive for failures
In addition to physical damage to the hard drive, there are also errors that can be “cured” using the built-in diagnostic tools of Windows 10. To fix more serious problems (for example, bad sectors), you can use third-party utilities, but after a while the disk will still have to be replaced.
Using the Command Line
Using the Command Line, you can run the built-in Check Disk utility, which checks the disk for errors and, if possible, corrects them. In a Windows environment, this program will not be able to check the system drive (drive C): it will prompt you to reboot and will check during the reboot before the OS starts.
If the chkdsk utility receives a system disk as input, it suggests rebooting the system to check it
The utility is launched in the “Command Line” (how to enter there is described above) using the chkdsk command<имя диска с двоеточием>with the given parameters:
- /f - auto-correction of found errors;
- /r - check for bad sectors and attempt to restore damaged information;
- /offlinescanandfix - offline scan, in which the program first “disconnects” the disk from processes in the system, and then checks it. Applies if the disk is in use and a “simple” run of Check Disk cannot fix the errors;
- /? - help on the command.
The command with the /r option can take up to several hours to complete.
As a result, chkdsk will display the disk data obtained during the scan
Video: how to check your hard drive for failures using chkdsk
Using StorDiag
The storage diagnostic utility is present only in Windows 10 and is not used in other versions of the system. Just like Check Disk, it is launched via the “Command Line” using the command stordiag.exe -collectEtw -checkfsconsistency -out<путь к папке, куда сохранится отчёт>.
StorDiag does not correct the errors found, but only diagnoses them and writes the received data to a report file. However, its diagnostic scope is wider than that of Check Disk, and if you are an advanced user, you can use this program to more accurately determine the cause of problems with your device.
Checking the disk using the StorDiag storage diagnostic utility will allow you to diagnose problems and write the resulting data to a separate file
Using PowerShell
Windows PowerShell is a Command Prompt shell used as another management tool in Windows. It is distinguished from a regular console by a wider range of applications, the ability to use scripts and other improvements.
PowerShell is located in the path “Start” - “All Programs” - “Windows PowerShell”. The console can also be found by simply typing its name in the Start menu search.
To check the disk, type in the PowerShell “Command Prompt” running as administrator (right-click on the PowerShell icon - “Run as administrator”) one of the following commands:
- Repair-Volume-DriveLetter<буква диска без двоеточия>- normal check with recovery;
- Repair-Volume-DriveLetter<буква диска без двоеточия>-OfflineScanAndFix - offline check (what it is was described above).
The specified commands entered in PowerShell will launch the disk diagnostic and treatment tool
Using Explorer and Control Panel
You can diagnose your hard drive for errors by running the diagnostic utility through Explorer. To do this, follow the path: “My Computer” - right mouse button on the disk that needs checking - “Properties” - “Service” - “Check for errors”. The check performed is similar to Check Disk.
Diagnostics and error correction can be started from the disk properties window
In addition, through the “Control Panel” you can activate system maintenance, which includes checking hard drives. It is located along the path “Start” - “Control Panel” - “Security and Service Center” - “Maintenance”. In the maintenance window, you can view the results of the previous scan or start it again using the “Start maintenance” button.
To start disk maintenance, you need to click on the corresponding button
Video: how to check your hard drive for errors using the built-in diagnostic utility
Windows Registry Diagnostics
The registry is another Windows component that often gets damaged, leading to crashes, glitches and freezes. To prevent this from happening, you need to periodically clean it, removing outdated branches, consequences of failures and erroneous entries.
Manually cleaning the registry is very labor-intensive and time-consuming. In addition, it is easy to make a mistake when carrying out this procedure, which can lead to negative consequences (including system crash). Therefore, we will touch upon the topic of manual cleaning in passing.
If you don’t want to waste time on manual cleaning, use one of the special programs that will automatically clear the registry of unnecessary and erroneous entries. The most popular of them is CCleaner - a free utility that not only corrects registry errors, but also cleans your computer of junk and accumulated temporary files. Let's figure out how to work with it.
You can download CCleaner from the official website of the developer.
Video: how to clean the Windows 10 registry manually and using CCleaner
When system failures are corrected, Windows begins to “fly” and delight the user with its impeccable work. Check the system for errors in a timely manner so as not to miss problems that have started, and it will serve you for a long time.
Not all errors are expressed in windows appearing on the desktop and the inability to perform any action. Much more often, they quietly accumulate on your computer and gradually slow down its operation. Periodically it is worth checking the device for possible errors, and not only the system, but also the hard drive and the registry. All methods described below also include automatic correction of detected faults.
How to check the system for integrity and errors
As a result of incorrect shutdown of the computer, exposure to viruses and other problematic situations, system files may be damaged or changed. The consequences of this, as a rule, are expressed in problems when launching certain programs or turning on the computer, but sometimes they can be invisible to the user. Scanning your system for integrity is the first thing we recommend doing when you encounter problems with Windows 10.
Via the sfc command
This is the main way to check the integrity of the operating system. It is intended for cases with problems with the computer's performance. The sfc command only performs a superficial analysis, which cannot be used to find and correct all possible errors. However, this method is quite fast and ideal for preventative computer scanning. A more in-depth analysis is possible through the DISM utility, which is described below.
The sfc command cannot fix errors in files that are currently in use by the system. If you receive a notification about such failures, be sure to run the DISM utility.
Via the DISM utility
The DISM utility conducts a full system scan for errors and integrity violations. The analysis it launches takes quite a long time, but allows you to identify and correct all violations in the operation of the system. To carry out the verification, you will definitely need the Internet.
Before running the utility, disable your antivirus and all running programs, and try not to use your computer during the analysis.
Open a command prompt as an administrator and type dism /Online /Cleanup-Image /RestoreHealth.
For a complete system integrity analysis, enter the command dism /Online /Cleanup-Image /RestoreHealth at the command line There are several more commands in this utility that may be useful to you:
- dism /Online /Cleanup-Image /CheckHealth to obtain information about the status and presence of damage to Windows components;
- dism /Online /Cleanup-Image /ScanHealth to check the integrity and damage of the component store.
How to check your hard drive for errors
All data recorded on the computer is divided into small fragments, which are placed on sectors of the hard drive. During computer operation, these sectors can become damaged. Damaged sectors are the “errors” of the hard drive. When a hard drive tries to read information from a damaged sector, the reading process is “stuck.” The result of this is that it takes an unreasonably long time to turn on the computer and launch some programs.
It is impossible to fix damaged sectors, but you can prevent the hard drive from working with them. The process of finding and eliminating these sectors is called defragmentation. Even if no errors are found, as a result of defragmentation, the space on the hard drive will become more organized, which will also speed up the process of reading information.
Through "Explorer"
This is the main way to check a hard drive. Windows 10 should do this automatically, without the user's knowledge, in order to maintain order on the hard drive. Defragmentation will take you about an hour, so it is better to leave it overnight.
Via the “Control Panel” (storage diagnostics)
Many people mistakenly believe that the storage diagnostic utility can be used to analyze the hard drive. Actually this is not true. The storage diagnostic utility is indeed present on the hard drive, but it starts automatically, and you will not be able to perform analysis through it. Using this method, you can only find out the results of the last hard drive status check.
If you just want to run an analysis, use the previous method, but instead of “Optimize,” click “Analyze.”
Via command line
This method eliminates the restoration of order on the hard drive, which is done during regular defragmentation. Due to this, the process proceeds much faster. Correcting errors this way is recommended if you need to quickly recover information from damaged sectors.
To check without using the Internet, use the command chkdsk C: /F /R /offlinescanandfix.
Via PowerShell
Windows PowerShell is a powerful new command-line shell. She does the same thing as her predecessor, but has much more powers. PowerShell allows you to quickly and easily perform actions that are difficult or impossible for a regular command line. In our case, this will help avoid the need to restart the computer to check the sectors in use.
To check without using the Internet, use the command Repair-Volume -DriveLetter C -OfflineScanAndFix.

How to check the registry for errors
The Windows Registry is a complex operating system database that stores all settings, changes, information about the computer and installed programs. If a registry error occurs, the consequences can be very different: from a blue screen when turned on and complete system inoperability to an undeletable shortcut and other little things.
The most annoying feature of registry errors is their layering. One minor error in the registry can lead to several others, which will ultimately lead to dire consequences. This is why regularly scanning the registry for errors and eliminating them early is extremely important to keep your computer running at peak performance.
Through built-in tools
Windows 10 has a built-in utility to check the registry for integrity, but it is quite weak and does not find most errors. Your best bet would be to use one of the third-party programs described below.
This method can only fix critical errors: many registry errors will remain untouched.
Open a command prompt as an administrator, type scanreg /fix and press Enter.
Enter the command scanreg /fix to check the registry through the built-in Windows 10 utility Via CCleaner
CCleaner is the most popular and reliable computer cleaning program. It is designed to clean debris from hard-to-reach places that the system itself cannot reach. However, CCleaner has earned its popularity precisely for its registry cleaning function, which allows you to quickly find and erase registry errors without affecting anything important.
Via Glary Utilities
Glary Utilities is a very functional program that will run in the tray and keep your computer clean and tidy. Cleaning the registry is just one of the available functions to improve the performance of your computer. Glary Utilities may seem intrusive to many, but for less experienced users it will be a very useful assistant.
Via Wise Registry Cleaner
Wise Registry Cleaner is a program designed not so much to treat the registry, but to completely clean it of stale and unclaimed parameters. Cleaning the registry using Wise Registry Cleaner is quite serious and can affect important files that the program will find unnecessary. When you launch Wise Registry Cleaner for the first time, you will be asked to make a backup copy of the registry, which you should agree to. If important files are affected, you can always rollback.
Wise Registry Cleaner is available only on the English version of the official website: if you change the page language to Russian, you will be offered another Wise Care 365 program.
Even if you don't see any errors on your computer, it's best to scan it periodically. This will ensure stable operation of the system and help solve most problems before they become noticeable.
Checking drive C for errors in Windows 7 and XP
There are moments in the life of a computer when logical errors occur in the file system on the hard drive. Errors on the disk can accumulate and not make themselves felt until a certain point. They can contribute to minor system glitches, or they can lead to complete destruction of the logical drive structure and loss of information. Errors on the disk most often occur as a result of incorrect access to the disk by some program, incorrect power shutdown, or the computer freezing during the data writing process. To avoid dire consequences, you should check the disk for errors.
There are two global cases: in the first case, Windows can be loaded at least in safe mode; in the second case, Windows does not boot, complaining about the lack of system files, or displaying a blue screen of death with error 0x000000ED (most often, but there may be another error).
Let us first deal with the simplest first case.
Checking a disk in Windows 7 is no different from checking a disk in Windows XP, so I will tell you using XP as an example.
To check the disk, run My computer, there right-click on the disk that you want to check and select from the menu that appears Properties. In the window that appears, you need to go to the tab Service and run the disk check program by clicking on the button Run check.
In the program window, check the box Automatically fix system errors and start the scan by clicking the Run button.
The disk will begin checking for errors and correcting them, after which a program report will appear. If in the report at paragraph In bad sectors If the value is different from zero, then you should check the disk using the Victoria program for bad sectors.
However, if the drive is a system drive, you will receive the following message: " Check Disk cannot be performed because it requires exclusive access to some Windows files on that drive, which requires a reboot. Schedule a disk check to run on the next system reboot?" and you will not be able to scan the disk right now. However, you can schedule a scan by clicking Yes.
After this, you should restart Windows. During boot, the disk will be checked for errors and corrected.
How to check your hard drive for errors if Windows won't boot
If Windows does not boot, you can still check the disk for errors. But for this you will need special software. We need a disk or flash drive with ERD Commander. The disk image can be downloaded. You can burn an iso image using the program DeepBurner. If you want to use a bootable USB flash drive, here are instructions for creating a bootable USB flash drive for ERD Commander.
So the preparatory work is completed, let's get down to business. Download ERD Commander for your version of Windows, although the version is not very important in this case. Checking the disk can be done in any version of ERD Commander, so here I will tell you how to check the disk for errors in ERD Commander for Windows 7.
Download ERD Commander, in the window that appears, refuse to connect to the network. In the next window, agree to redistribute the drive letters so that they match the system ones. Select your operating system from the list. In the Commander menu that appears, select Command line. Now you need to enter the command to check the disk chkdsk c: /f(in case of checking drive C) or chkdsk d: /f(if you need to check drive D for errors) and press Enter. If a message appears like the picture below " Would you like to force a dismount on this volume? ", which translates to "Do you want to unmount this partition?", enter from the keyboard Y and press Enter, thereby agreeing to unmount the disk.
The disk will begin checking and correcting errors, after which a report of errors and corrections will be displayed.
Please note that the value in bad sectors is equal to 0. If it is greater than zero, then the disk has bad sectors and you should check the hard drive for bad sectors.
Once the scan is complete, you can turn off or restart your computer.
