Time to do the ESD shuffle I think.

Yeah, I've got someone upstream in my chain of command who's a huge
fan of seacrates, so that's how we got those 1.5TB drives. Our 15k5
seagates have been great, with 2 failures in 32 drives in 1.5 years of
very heavy use. All our seagate SATAs, whether 500G or 2TB have been
the problem children. I've pretty much given up on Seagate SATA
drives. The new seagates we got are the consumer 7200.11 drives, but
at least they have the latest firmware and all.
