This guide shows you how to use the chkdsk command in Windows 11 to keep your hard drive healthy.

Why use chkdsk? Your computer stores data on your hard drive. Sometimes, files or sectors on that drive get corrupted. chkdsk (short for “Check Disk”) scans your drive to find these issues and attempts to fix them so your computer runs smoothly.

What happens when done? Once the scan finishes, Windows will report any errors it found and tell you if it was able to repair them. This helps prevent crashes and data loss.

Run chkdsk from File Explorer

If you prefer using a visual menu rather than typing commands, follow these steps:

Open open File Explorer or press the Windows key + E on your keyboard.
Select This PC from the left sidebar.
Right-click on the drive you want to check and select Properties.

For more control, you can use the command line. Note: This requires admin privileges.

Open Windows Terminal as an administrator.
Select Windows PowerShell or Command Prompt.
Type the following command to check and fix errors (replace C: with your actual drive letter):

chkdsk C: /f

If you want to run a deep scan that fixes errors the next time your computer starts up, use this command:

chkdsk C: /f /offlinescanandfix
