Publisher| chkntfs |
specifies whether to schedule
automatic filesystem checking (using
chkdsk) to be run at startup.
Syntax
chkntfs volume [...]
chkntfs /d
chkntfs /t[:time]
chkntfs /x volume [...]
chkntfs /c volume [...]
Options
- volume [...]
Displays the filesystem of the volume(s) and, if automatic file
checking is scheduled, whether the volume has been corrupted. (If so,
then run chkdsk /f.) The volume
may be identified by a drive letter with colon, a volume mount point,
or a volume name.- /d
Restores default behaviorexcept countdown timefor
automatic file checking (use this switch alone). In other words, all
drives are checked at startup, and those found to be dirty have
chkdsk run against them.- /t[:time]
Displays or specifies countdown time for automatic filesystem
checking.- /x
Excludes specified volume from being checked (even if volume is
marked for running chkdsk). To exclude multiple
volumes, list them in one command. (This option
isn't accumulative.)- /c
Checks the specified volume at startup. (This option is accumulative.)
Examples
Display the filesystem on drive C: and its
current state:
chkntfs c:
The type of the file system is NTFS.
C: is not dirty.
Show the countdown time for automatic filesystem checking:
chkntfs /t
The AUTOCHK initiation count down time is set to 10 seconds.
Change the countdown time to 60 seconds:
chkntfs /t:60
Specify that only C: be checked at startup on a
system that also has D: and
E: as fixed drives:
chkntfs /d
chkntfs /x C: D: E:
chkntfs /c C:
In this example:
- The first command resets the default setting, which causes all
volumes to be checked at startup. - The second command excludes all volumes from being checked.
- The third command schedules C: alone for
checking.
Notes
- You must be a member of the local Administrators group to use the
chkntfs command. - The default behavior of chkntfs is to check all
volumes at startup. - Don't set the countdown time to zero, as checking
the filesystem can be very time-consuming and the user will be unable
to cancel this operation. (chkdsk
can't be stopped once it is running.)
