   Hmm...I think it's about 40,000 hrs. (high?) We had one commit suicide
last summer and decided it was time to have the rest retired (Didn't even
bother sparing the bad sectors). The SCSI-2's that replaced them are
350,000+ hr. MTBF drives (about 39 yrs.(!)) and are about 1000% faster. Its
the way to go. Besides, then you wont have to help the HP techs with the
"crane." Good recovery skills, though. :-)
I understand the fast-wide's are getting on to 500,000 hr MTBF. I'm jealous.
