CHKDSK

Checks the status of a disk and displays a status report. Can also fix disk 
errors.

The status report shows errors found in the MS-DOS filing system, which
consists of the file allocation table and directories. CHKDSK also displays
a summary of disk usage. (CHKDSK does not verify that the information in
your files can be accurately read.) If errors exist on the disk, CHKDSK
alerts you with a message.

Note: The ScanDisk program is the preferred method of fixing drive
      problems, and should be used instead of the CHKDSK /F command. For
      more information, see the <SCANDISK> command.

Syntax

    CHKDSK [drive:][[path]filename] [/F] [/V]

To display the status of the disk in the current drive, use the following
syntax:

    CHKDSK

Parameters

drive:
    Specifies the drive that contains the disk that you want CHKDSK to
    check.

[path]filename
    Specifies the location and name of a file or set of files that you want
    CHKDSK to check for fragmentation. You can use wildcards (* and ?) to
    specify multiple files.

Switches

/F  Fixes errors on the disk. Do not use this option when running CHKDSK
    from other programs; for more information, see "Using CHKDSK With Open
    Files" in <CHKDSK--Notes>. In general, when fixing disk errors, use
    <ScanDisk> instead of CHKDSK.

/V  Displays the name of each file in every directory as the disk is
    checked.
