I have found that the Buslogic SCSI disk verify does not find bad sectors
that the Adaptec disk verify does.  I don't know why this is, but it's
repeatable on more than one disk.

Reformatting with either seems to cure the bad sectors (i.e., they're
either fixed or mapped) but I now make it a practice to scan the disks
with my Adaptec 1542 rather than the Buslogic 445 whenever I'm trying
to fix or map bad sectors that appear in a running system.

And no, I haven't contacted Buslogic about it either.  Haven't had time yet.
