Command and parameters
For making things easier, here are some commands and their parameters.
<volume> Specifies the drive letter (followed by a colon), mount point, or volume name.
[ [<path>] <filename> Use with file allocation table (FAT) and FAT32 only. Specifies the location and name of a file or set of files that you want chkdsk to check for fragmentation. You can use the ? and * wildcard characters to specify multiple files.
/c is used for only NTFS volumes only.
/f is used to fix errors on any disk that you selected.
/l is used only in NTFS volumes. It is used to perform the checking of index entries.
/i is used only in NTFS volumes. It is used to perform the checking of index entries. It is used for less vigorous checking.
/r implies that /f and /p. Is used to locate bad sectors.
/v is used to display the name of each file, and also to show every directory.
/x forces volume to dismount.
/b for only NTFS volumes. It is used to rescan and also to free clusters of errors.
/scan in NTFS volumes. Is used to scan your drive online.
/scan, NTFS, online scan
/forceofflinefix Use with NTFS only (must be used with /scan). Bypass all online repair; all defects found are queued for offline repair (for example, chkdsk /spotfix).

/spotfix Use with NTFS only. Runs spot fixing on the volume.
/sdcleanup Use with NTFS only. Garbage collects unneeded security descriptor data (implies /f).
/offlinescanandfix Runs an offline scan and fixes the volume.
/freeorphanedchains Use with FAT/FAT32/exFAT only. Frees any orphaned cluster chains instead of recovering their contents.
/markclean Use with FAT/FAT32/exFAT only. Marks the volume clean if no corruption was detected, even if /f was not specified.
/? Displays help at the command prompt.
