Syntax:-

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

Explanation:
 volume    : Specifies the drive letter (followed by a colon), mount point, or volume name.
 filename  : FAT/FAT32 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            : Locate 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- Skip checking of cycles within the folder structure.
 /B            : NTFS only-Re-evaluates bad clusters on the volume(implies /R)  

   If you want to specific  drive then you can enter the command like below

chkdsk C:
