[mdlug] [WLUG] reiserfsck and badblocks

[David Relson]

Whether ReiserFS is good or bad is a subject for a different thread.

At present my goal is to get the bad block marked as such and then see
what shape the drive is in.  That info will let me decide if my backups
are good (or not) and if the drive needs to be replaced.
