I don't think that chkdsk would do you any good for marking off the bad 
sector for use in a linux system. Also, the one bad block usually is a 
warning that the whole disk is on the way to total failure.

On computers that I had a totally corrupted filesystem and thought 
reinstalling the OS (M$ on these computers) the bad blocks did not show 
on the reformatted system. The disk did fail again within 6 months, so 
replacing the disk is probably you safest option.

If the disks that are failing are IBM/Hitachi I'd certainly get rid of 
the disks. Other vendors might not be as high of a risk.

Just my opinion. No technical research on my part.
