Syntax
MS-DOS, Windows 95, Windows 98, Windows ME
chkdsk syntax
Checks a disk and displays a status report.
CHKDSK [drive:][[path]filename] [/F] [/V]
| [drive:][path] |
Specifies the drive and directory to check. |
| filename |
Specifies the file(s) to check for fragmentation. |
| /F |
Fixes errors on the disk. |
| /V |
Displays the full path and name of every file on the disk. |
Type CHKDSK without parameters to check the current disk.
Windows 2000 and Windows XP chkdsk syntax
Checks a disk and displays a status report.
CHKDSK [volume[[path]filename]]] [/F] [/V] [/R] [/X] [/I] [/C]
[/L[:size]]
| volume |
Specifies the drive letter (followed by a colon), mount point, or volume name. |
| filename |
FAT only: Specifies the files to check for fragmentation. |
| /F |
Fixes errors on the disk. |
| /V |
On FAT/FAT32: Displays the full path and name of every file
on the disk. |
| /R |
Locates bad sectors and recovers readable information (implies /F). |
| /L:size |
NTFS only: Changes the log file size to the specified number
of kilobytes. If size is not specified, displays current size. |
| /X |
Forces the volume to dismount first if necessary. All opened handles to the volume would then be invalid
(implies /F). |
| /I |
NTFS only: Performs a less vigorous check of index entries. |
| /C |
NTFS only: Skips checking of cycles within the folder structure. |
The /I or /C switch reduces the amount of time required to run Chkdsk by
skipping certain checks of the volume.
Microsoft Windows 2000 and Windows XP users who have
NTFS
should also
consider using the CHKNTFS command.
Windows 2000 and Windows XP recovery console chkdsk syntax
Note: The below options are only available in the
recovery
console.
Checks a disk and displays a status report.
chkdsk [drive:] [/p] | [/r]
| [drive:] |
Specifies the drive to check. |
| /p |
Check even if the drive is not flagged dirty, bad. |
| /r |
Locates bad sectors and recovers readable information (implies /p).
|
Chkdsk may be used without any parameters, in which case the current drive is checked with no switches. You can specify the listed switches.
Chkdsk requires the Autochk.exe file. Chkdsk automatically locates Autochk.exe in the startup (boot) directory. If it cannot be found in the startup directory, chkdsk attempts to locate the Windows 2000 Setup CD. If the installation CD cannot be found, chkdsk prompts for the location of Autochk.exe.
Examples
chkdsk Will display all information described above and also
report any crossed linked files. chkdsk /f Will fix any crossed linked files; however, do not run this command while
you are in Windows95 or Windows 3.x
