Solution 2. Run CHKDSK Scan to Repair Damaged Hard Disk

When the hard drive's file system gets corrupt and you can't access the hard disk, you can run a CHKDSK scan to repair the corrupt hard drive without formatting.

CHKDSK command prompt checks the file system and file system metadata of a volume for logical and physical errors. If used without parameters, CHKDSK displays only the volume's status and does not fix any errors. If used with the /f, /r, /x, or /b parameters, it fixes errors on the volume.
