(Related to, but different from: In chkdsk, what is an online scan?.)
Running Windows 8.0 Pro,
chkdsk has a
/spotfix option that
Runs spot fixing on the volume. What is spot fixing? If it relates to fixing the drive online, I thought
/forceofflinefix handles that.
EDIT: It may be related to not fixing errors upon detection, but saving the spots and fixing them later.
Here's the full options:
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 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. The /I or /C switch reduces the amount of time required to run Chkdsk by skipping certain checks of the volume.
