Fix Hard Disk Problems in Windows 7/8/10

Use Windows CheckDisk (CHKDSK) to scan the hard drive for errors (such as lost sectors, bad sectors and corruptions) and fix them.

  1. Click on the Start Button then click on Computer:

    Start - Computer

  2. Then, right click on the drive you wish to scan for errors and select Properties:


  3. Click Tools then Check Now under error-checking:


    Leave Automatically fix file system errors checked. That will find and repair problems. Perform a deeper scan by checking Scan for and attempt recovery of bad sectors.

  4. Click Start.

    Check Now

    If the disk chosen is in use, a message will appear asking if you wish to schedule a scan. Clicking on Schedule disk check will cause the scan to run the next time the computer is restarted.

    Schedule Scan

The scan will take several minutes depending upon the size of the drive and the options set for the scan.

If the problem started just recently and CheckDisk didn't resolve it, try a Windows System Restore (completely safe) which will restore Windows to a previous state when the problem might not have existed. (See Windows Help.)
