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

Prameters:


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.
                         On NTFS: Displays cleanup messages if any.
  /R                  Locates bad sectors and recovers readable information (implies /F, when /scan not specified).
  /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.
  /B                 NTFS only: Re-evaluates bad clusters on the volume (implies /R)
  /scan            NTFS only: Runs a online scan on the volume
  /forceofflinefix    NTFS only: (Must be used with "/scan") Bypass all online repair; all defects found are queued for offline                        repair (i.e. "chkdsk /spotfix").
  /perf             NTFS only: (Must be used with "/scan") Uses more system resources to complete a scan as fast as possible.                             This may have a negative performance impact on other tasks running on the system.
  /spotfix        NTFS only: Runs spot fixing on the volume
  /sdcleanup  NTFS only: Garbage collect unneeded security descriptor data (implies /F).
  /offlinescanandfix  Runs an offline scan and fix on the volume.
  /freeorphanedchains FAT/FAT32/exFAT only: Frees any orphaned cluster chains instead of recovering their contents.
