Hmmm... May I *STRONGLY* urge you to replace the 1950's ASAP. We've
surplussed all of ours. We started to lose them to hardware issues: I
think it was the RAID controller dying. We were really amazed at the
quality control... - in a short time (literally weeks) we had several
(three? four? five?) die with this error. I'd say you're on borrowed time.
