I found a web site that recommended running chkdsk with the "/b"
command-line option, but I can't find any information about this option.
What does it do?

Thanks,
Chris
 
Hi,

You should reference the website.
I think they made a typo.
There is no /b option. (At least as far as XP goes)

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


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).
/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.

The /I or /C switch reduces the amount of time required to run Chkdsk by
skipping certain checks of the volume.

It doesn't do anything other than report an error as that is not a valid
switch. Either the website had a typo and a different switch was
actually used, or you misread the site. Chkdsk b: is the closest valid
command, that would check the volume assigned to drive letter B for errors.

There is a /p switch, used only in when running chkdsk from the recovery
console. Use /p instead of /f.
