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.
