hello,
       I'm having problems with the hard disk on an IBM AT. Having swapped
the controller and re-FORMATed it, the read errors have gone but I find I
have 300KB of bad sectors.
  Could it be that the flaky controller caused the BIOS to mark the sectors
as bad even though the media is OK? Deleting and re-creating the partition
does nothing useful. If I do a low-level format will this revive the dead
sectors? Can somebody please tell me the BIOS (?) address to jump to in
order to do the low-level format? (Ive seen it before but never noted it..)

thanks!
