CHKNTFS

Displays or modifies the checking of disk at boot time.

CHKNTFS volume [...]
CHKNTFS /D
CHKNTFS /T[:time]
CHKNTFS /X volume [...]
CHKNTFS /C volume [...]

  volume         Specifies the drive letter (followed by a colon),
                 mount point, or volume name.
  /D             Restores the machine to the default behavior; all drives are
                 checked at boot time and chkdsk is run on those that are
                 dirty.
  /T:time        Changes the AUTOCHK initiation countdown time to the
                 specified amount of time in seconds.  If time is not
                 specified, displays the current setting.
  /X             Excludes a drive from the default boot-time check.  Excluded
                 drives are not accumulated between command invocations.
  /C             Schedules a drive to be checked at boot time; chkdsk will run
                 if the drive is dirty.

If no switches are specified, CHKNTFS will display if the specified drive is
dirty or scheduled to be checked on next reboot.
