CHKDSK - Dos Command :

To view 'chkdsk' with its all possible parameters you can use following command. Its like help information to regarding that command.


Commands can be run using Microsoft Windows XP Command Prompt (cmd.exe)

Syntax :
CHKDSK [volume[[path]filename]]] [/F] [/V] [/R] [/X] [/I]
[/C] [/L[:size]]


volume --> It specifies the drive letter (followed by a colon), mount point, or volume name.

filename --> FAT/FAT32 only: It specifies the files to check for fragmentation.

/F --> It fixes errors on the disk.

/V --> On FAT/FAT32: It displays the full path and name of every file on the disk.
On NTFS: It displays cleanup messages if any.

/R --> It locates bad sectors and recovers readable information (implies /F).

/L:size --> NTFS only: It changes the log file size to the specified number of kilobytes. If size is not specified, displays current size.

/X --> It forces the volume to dismount first if necessary. All opened handles to the volume would then be invalid(implies /F).

/I --> NTFS only: It performs a less vigorous check of index entries.

/C --> NTFS only: It 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.

chkdsk D: /F
