                             CHKDSK

The CHKDSK external command checks your disk or diskette and displays a report
on the disk and memory status.

    CHKDSK [d:][filename[.ext]][/F][/V]

[d:] specifies the disk letter to be checked. If omitted, the default drive is
    used.

[filename[.ext]] is an optional filename (A directory path is not allowed, but
    wildcards may be used.) If you specify a filename, CHKDSK will display the 
    number of fragmented areas occupied by the file(s). The more fragmented
    areas (separate from the rest of the file) that files occupy, the slower
    the computer runs.

/F causes CHKDSK to correct some types of errors found on the disk, and
    attempt to recovered data into files with names of the form FILEnnnn.CHK,
    where nnnn starts with 0000.

/V displays information about each file and directory CHKDSK encounters, plus
    disk errors (if any).

CHKDSK won't work for disks on another computer in a network. CHKDSK should
not be used for ASSIGNed, JOINed, or SUBSTed drive letters.
