Would it happen to be a Caviar 21000 series? We had a lab full of them
(P5/120 Linux workstations). Turns out they had a firmware defect that
*really* showed up under heavy access (read: non-windoze). WD shipped us
a firmware upgrade, but, as we found out, ten minutes worth of access on
the drive already did the damage, of the 29 machines, all but 5 have been

WD fixed the problem before introduction of the 31000.
