How to fix and diagnose file system errors with CHKDSK. – wintips.org

If your computer is slow, crashes or freezes when you try to access files or programs, you may be experiencing hard drive errors. Fixing and diagnosing your hard drive errors can save you from a bad situation like losing your important files forever, but it can also fix several Windows problems on your system.

Windows Disk Checker (ChkDsk) can diagnose and repair file system errors that may occur after a power outage or after an intermittent Windows update or software installation. Note that you can use Disk Checker to detect problems with all hard drives or removable devices (such as USB memory sticks) attached to your computer.

In the previous guide, I mentioned how to check and diagnose hard disk drive (HDD) for hardware problems. In this article, I’ll show you how to detect and fix file system errors using the Windows “CHKDSK” command, as well as how to determine the health status of your disk by reading the Disk Check results (log) after it’s done. .

Part 1. How to detect, repair, and fix file system errors with Disk Checker.

Part 2. How to View the Disk Details Audit Log.

Part 1. Detect, repair and repair file system errors (Windows 8, 7, Vista and XP).

Please note: You can run Disk Checker from the Windows GUI or from the command line. However, if you have a Windows 8 (or 8.1) computer, it is better to run the disk checker from the command line, because the Windows 8 GUI does not have the ability to scan and repair bad sectors. (In that case, I prefer to always run “Chkdsk” using the command line method on any operating system).

Method 1: Use the Check Disk tool in the Windows GUI.

Method 2: Run Disk Checker from the command line

Method 1: How to Run Disk Checker from Windows GUI

1. Open Windows Explorer (click Win + E keys).

2. Right-click the drive you want to diagnose and fix (for example, your primary (root) drive “C:”) and select Characteristics.

b. press Check now if you have Windows 7, Vista or XP.

4a. press Scanning if you have Windows 8 or 8.1.

4b. check “Scan for bad sectors and try to recover” check box and then click Start if you have Windows 7, Vista or XP (see screenshot).

5a. If the disk is in use, Windows will ask you to schedule a scan the next time you start the computer. When you receive this message:

  • Choose Schedule a disk check
  • press OK to exit disk properties.
  • Close all programs and restart your computer.

5b. If the drive is not in use, the scan/repair process will start immediately, and you should get an informational message when it’s finished (like the screenshot below).

6. Go to part 2 to see the disk check details (health status).

Method 2: How to run Disk Check from the command line.

Before proceeding: Restart your computer once (to close all open programs) and disable any antivirus and/or backup programs currently running on your system.

1. Open an elevated command prompt. For this:

In Windows 7 & Vista go to:

  • Start > All Programs > Accessories
  • That’s right– press at”Command line” and select “Run as administrator“.

In Windows 10, 8 & 8.1:

  • Right click on the screen lower left corner and from the pop-up menu “Command Prompt (Admin)“.

command line -admin

2. In the Command Prompt window, type the following command * and press Enter:

  • chkdsk %driveletter% /f /r

*Note: As %driveletter%, type the drive letter (eg C:, E:, F:, etc.) of the drive you want to check for errors as seen in Windows Explorer.

For example:

  • If you want to check and repair the C: (Windows installed) root drive, you need to enter this command (no need to specify the drive letter for the root drive): chkdsk /f /r
  • If you want to check and repair another drive (for example, the “E:” drive), you should enter the following command: chkdsk e: /f /r

check disk

3a. If you want to check the root drive (“C:”), you should get a “” prompt.Chkdsk cannot start because the volume is being used by another process. Do you want to schedule this sound to be checked the next time the system reboots? (Y/N)” (see screenshot below).

  • Answer Yes answer this question by clicking the button Y key on your keyboard and press Enter.
  • Restart your computer

3b. If you want to check a drive other than the root volume (disk), you should get a “message-question”.Chkdsk cannot start because the volume is being used by another process. Chkdsk can run if this folder is deleted first. THEN ALL HANDLES OPENED TO THIS CIRCLE WILL BE INVALID. Do you want to force-mount this folder? (Y/N)” (see screenshot below)

  • Answer No answer this question by clicking the button N key on your keyboard and press Enter.

Then you should get another message – the question says: “Chkdsk cannot start because the volume is being used by another process. Do you want to schedule this sound to be checked the next time the system reboots? (Y/N)

  • Answer Yes answer this question by clicking the button Y key on your keyboard and press Enter.
  • Restart your computer

4. After restarting, the disk check process should start. Wait while Windows checks for disk errors.

5. After the disk check is complete, Windows should enter Windows normally. Follow the instructions below to read the disk check log file.

Part 2. How to view Disk Checker scan results.

To view the disk check log (hard disk health status), you need to go to Windows Event Viewer. For this:

1. Click on “WindowsPicture-201_thumb_thumb_thumb_thumb1_t + “RClick the ” button to download Running dialog box.

2. Type eventvwr and press Enter To open the event viewer.

5. Here you can see a detailed log that includes all actions and file system repairs after the file system check.

6. To find out the health status of your drive, scroll down (using the scroll bar on the right) and read the KB value. bad networks series:

  • There must be value 0 (zero) on a healthy file system.
  • If you see a positive value (for example, “100 KB in bad sectors”), there are problems with the file system, most likely your disk is defective (incorrect) due to hardware problems and you need to replace it. (see suggestions below)

Suggestions:

  • Always back up your important files to another storage medium (such as a USB memory stick, external hard drive, DVDROM, etc.) and keep this media offline (Unplugged).
  • Before proceeding with hard drive replacement, learn how to check and diagnose the drive for hardware errors.

That’s it!
