Disklabel your drive such that you have the bad144 stuff enabled. Get a kernel that actually reports bad sectors. Read appropriate portion of drive and take note of reported errors (dd if=/dev/rwd0d of=/dev/null bs=<one_cylinder>) /* hmm... you may want to use the c 'partition' instead if you're running something else on that drive apart from 386bsd */ bad144 (-v) -a -c the appropriate bad sectors .... Well, it works for me and my wd-1009.
