The absolute first thing you should do is to back up any data that you
might possibly need from this drive.

Then do a verify, this will try to blank out the disk.  If this fails
(possibly because the defect lists are screwed up) then I recommend that
you install sformat from ftp.fokus.gmd.de (you'll need the scg kernel
driver as well).  It can do remarkable low-level SCSI wizardry and if the
disk is fixable it should be able to do it.

Do not continue to use this drive without wiping it clean and analyzing it
first.
