.. chkdsk has optional parameters
Q: \> chkdsk /?
Checks a disk and displays a status report.
CHKDSK [volume [[path] filename]]] [/ F] [/ V] [/ R] [/ X] [/ I] [/ C] [/ L [: size]]
[/ B] [/ scan ] [/ spotfix]
volume Specifies the drive letter (followed by a, colon), mount
point, or volume.
Filename FAT / FAT32 only: Specifies the files to be
checked for fragmentation.
/F Corrects errors on the disk.
/V FAT / FAT32: Displays the full path and name of each
file on the disk.
NTFS: Displays cleanup messages, if any.
/R Finds bad sectors and makes readable ones
(conditional / F if / scan is not specified).
/L : size NTFS only: Changes the size of the log file to the
specified number of KB. If the size is missing,
the current size is displayed.
/X Forces the volume to be dismounted first, if necessary
. All open handles to the
volume then become invalid. (conditional / F).
/I NTFS only: Carries out a relaxed check of the
/C NTFS only: Skips checking cycles
within the folder structure.
/B NTFS only: Reevaluate bad clusters on the volume
(conditional / R).
/scan NTFS only: Performs an online scan of the volume.
/forceofeltafix NTFS only: (Must be used with "/ scan".)
Bypasses all online repairs. Any
errors found are queued for offline
repair (ie "chkdsk / spotfix").
/perf NTFS only: (Must be used with "/ scan".)
Uses more system resources to complete a scan as
quickly as possible. Doing so can adversely
affect the performance of other tasks running on the system
/spotfix NTFS only: Repairs damage to the volume.
/sdcleanup NTFS only: does not perform garbage collection
required safety description data from (conditional / F).
/offlinescanandfix Performs offline scan and repair on the volume.
/freeorphanedchains FAT / FAT32 / exFAT only: Releases orphaned cluster chains
instead of restoring their contents.
/markclean FAT / FAT32 / exFAT only: Marks the volume as healthy
if no damage is detected, even if
"/F" is not specified.
The / I or / C option reduces the time it takes to run
Chkdsk by skipping some checks on the volume.
