Hmm. The chipset is an SiS 530, and it's not really 1.6.1, it's 1.6.1
+ selected pull-ups from 1.6.2, to let the drives use UDMA mode 4.
Forcing them to UDMA mode 2 didn't help, though. Moreover, I don't
have any such problem with the Seagate ST3120023A. After replacing the
WD with a Seagate, I haven't seen the problem recur. It's not a very
good case, either -- any drive in that position gets hot to the touch,
but the Seagate evidently can handle the heat better.
