Displays or specifies whether automatic system checking is scheduled to be run on a FAT, FAT32, or NTFS volume when the computer is started.
chkntfs volume: [...]
chkntfs [/x volume: [...]]
chkntfs [/c volume: [...]]
volume: [...] : Required. Specifies the drive letter (followed by a colon), mount point, or volume name. Displays a message that identifies the file system of the specified volume. If automatic file checking is scheduled to be run, this parameter displays a message indicating whether the volume has been corrupted, which requires you to run chkdsk.
/d : Restores all chkntfs default settings, except the countdown time for automatic file checking. Default behavior is to check all volumes when the computer is started.
/t[:time] : Changes the Autochk.exe initiation countdown time to the specified amount of time entered in seconds. If you do not specify :time, /t displays the current countdown time.
/x volume: [...] : Excludes the specified volume from being checked when the computer starts, even if the volume is marked as requiring chkdsk.
/c volume: [...] : Schedules the specified volume to be checked when the computer starts.
/? : Displays help at the command prompt.
To display the Autochk.exe initiation countdown time, type:
When changing the Autochk.exe initiation countdown time, type the time in seconds. For example, to change the countdown time to 30 seconds, type:
The /x command-line option is not accumulative. If you type it more than once, the most recent entry overrides the previous entry. To exclude multiple volumes, list them all in one command. For example, to exclude both the E: and F: volumes, type:
chkntfs /x e: f:
To exclude the F: volume only, type:
chkntfs /x e:
chkntfs /x f:
The /c command-line option is accumulative. If you want to check the specified volume only, reset the defaults to clear any previous commands, exclude all volumes from being checked, and then schedule automatic file checking on the desired volume.
For example, to schedule automatic file checking on the D: volume only, type:
chkntfs /x c: d: e:
chkntfs /c d:
