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 count down 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 runs if the drive is dirty.

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