CHKDSK (short for Checkdisk) is a command in DOS and Microsoft Windows systems that verifies a hard disk or a floppy disk for file system integrity. It is similar to the fsck command in Unix.

[edit] Windows NT based

Under Windows NT, Windows 2000, Windows 2003, Windows XP and Windows Vista, CHKDSK can also check the disk surface for bad sectors, a task previously done by SCANDISK. CHKDSK can also fix errors.

[edit] Using the Recovery Console

When using the Windows Recovery Console, the CHKDSK command can use the following options:

/F: Does an exhaustive check of the drive and corrects any errors.
/R: Locates bad sectors and recovers readable information.

Note: If you specify the /r option, the /f option is implied. When you specify the chkdsk command without arguments, the command checks the current drive with no options in effect (read-only mode).
