We don't have a method for actually mapping & tracking bad blocks.
Most new drives have something called S.M.A.R.T. which is supposed to
keep track of bad blocks internally to the drive, and move things around
as necessary.
(see http://csl.cse.ucsc.edu/smart.shtml)
This tool should help you know when your drive is going bad, so you can
replace it before errors happen. By the time the filesystem actually
starts seeing bad blocks, (i.e. the drive can no longer cope) I think
it's time to replace the drive, regardless of the filesystem you're
using.
