To scan a different drive,
include the drive letter as one of the command-line options,
like this: chkdsk d: /f.
The other important options available to Chkdsk are the following:
/r The /r parameter is essentially the same as /f, except that it also scans
for??”and recovers data from??”bad sectors, as described earlier. This
just takes longer, and probably isn??™t necessary unless /f is insufficient.
/b When Chkdsk finds a bad sector (as the result of an /r scan), it effectively
???fences off??? the region so Windows can never store data there
again. Use the /b parameter to recheck those regions in the hopes that
they can be used once again. For obvious reasons, this is usually not a
good idea, and is pretty much a big waste of time.
/x Include this option to force Windows to dismount the volume before
scanning the drive, a useful step for drives with shared folders (see
Chapter 8). If you don??™t include /x, and the drive is in use, Chkdsk usually
has to schedule a scan during the next boot. The /x parameter
implies the /f option.
There are also the /i and /c options, which are used only to skip certain
checks in order to complete the scan more quickly; there??™s usually no reason
to use them.
To run Chkdsk from Windows Explorer, right-click any drive, select Properties,
choose the Tools tab, and click Check Now. Here, the Automatically fix
file system errors option corresponds to the /f parameter, and the Scan for
and attempt recovery of bad sectors option corresponds to the /r parameter.
