CHKDSK utility – Scan your hard drive for errors

The Check Disk (CHKDSK) utility is a powerful tool that examines and repairs issues within the file system, maintaining the integrity of your storage drives.

CHKDSK, which stands for Check Disk is a command-line tool, that can scan your hard drive or SSD for errors and bad sectors, and fix them if possible. Hard disk errors can occur due to physical damage, power failures, malware infections, or improper shutdowns and can cause data loss, corruption, or system instability.

To check the disk drive for errors:

  • Press the Windows key + E to Open File Explorer and right-click on the drive that you want to check.
  • For example, if you want to check your F: drive, right-click on it and select Properties. Go to the Tools tab and click on Check under Error checking.
  • You will see a window that says “You don’t need to scan this drive”. This means that Windows 11 has not detected any errors on your drive. However, you can still scan it for errors by clicking on Scan Drive.

Depending on the size and condition of your drive, this may take a while to complete. You may also need to restart your PC to finish the repair.

Run chkdsk command with additional parameters:

Alternatively, you can run CHKDSK from an elevated Command Prompt or PowerShell window. To do this, press Windows + X and select Command Prompt (Admin) or PowerShell (Admin).

Type chkdsk C: /f /r /x and press Enter. Replace C: with the drive letter that you want to check.

  • The /f parameter tells CHKDSK to fix any errors it finds.
  • The /r parameter tells CHKDSK to scan for bad sectors and recover any readable information.
  • The /x parameter tells CHKDSK to dismount the drive before scanning it.

Note that if you are checking your system drive (usually C:), CHKDSK will ask you to schedule the scan for the next restart. Type Y and press Enter to confirm.

Check Disk Errors

 CHKDSK scans for and corrects disk errors, bad sectors, and other file system inconsistencies.

CHKDSK will scan your drive for any errors or bad sectors, and try to fix them by marking them as unusable or recovering any readable data from them. This can help you avoid data loss or corruption, and improve the reliability of your drive. However, CHKDSK cannot fix physical damage to your drive, such as scratches or cracks. If your drive is severely damaged, you may need to replace it with a new one.

When CHKDSK finishes, it will display a summary of its results. You can also view the details by opening the Event Viewer and navigating to Windows Logs > Application. Look for events with the source Chkdsk.

SFC and DISM tool – Repair Corrupted Windows System Files

SFC and DISM are powerful command-line tools that focus on the integrity of system files and Windows images, respectively.

The SFC (System File Checker) and DISM (Deployment Image Servicing and Management) are two command line tools that help scan and repair corrupted system files on your Windows 11 PC. System files are essential components of your operating system that enable various functions and features. If these files are damaged or missing, they can cause various problems such as crashes, errors, or missing features.

System files can get corrupted or damaged by malware, power outages, or improper shutdowns

To run the SFC or DISM command on Windows 11/10

When SFC finishes, it will display a message saying whether it found any integrity violations and whether it was able to fix them.

Run DISM command:

If SFC says that it could not fix some files, you may need to run DISM to repair the system image. The system image is a file that contains the configuration and settings of your Windows 11 installation. If the system image is corrupted, SFC may not be able to access or restore some system files.

  • To run DISM, type dism /online /cleanup-image /restorehealth and press Enter. This command will scan the system image and repair any corruption or inconsistency it finds.
  • Wait for the scan to complete. It may take longer than SFC depending on the extent of the damage and the speed of your PC.
  • When DISM finishes, it will display a message saying whether it found any corruption and whether it was able to fix it.

DISM restore health command

SFC scans and repairs corrupted or missing system files, while DISM can fix Windows image issues and enhance the overall system health.

After running DISM, you may need to run SFC again to verify and repair any remaining system files. Type sfc /scannow and press Enter. When both SFC and DISM finish, you should restart your PC to apply the changes and check if your problems are resolved.
