   volume    The disk, drive or partition that you wish to check, 
             for instance: chkdsk a: Would check the A drive. If no 
             volume is given, the current drive is assumed.
   /f        Tells chkdsk to attempt to fix any errors.
   /d files  This will list the level of fragmentation for 
             each file. If many files are very fragmented then 
             disk operation can be slow. You can defragment your 
             disk drive with defrag.
             This option also lists the file attributes for each 
             file, see attrib for more information about file
   /r        Scans for and attempts to recover data. This may need
             a long time!
   /s        Tells chkdsk not to check the drive, but only to 
             display the drive analysis.
   /v        This lists the files as they are being checked. 
             Note that this can slow things down, especially if 
             there are many files.
  CHKDSK has the following EXITCODES (ERRORLEVEL):
    0    drive okay
