They're ancient, yeah.. but note that the ECC fixed *all* the soft
errors...just doing it's job.

HDA is reporting the sort of errors I'd worry about, but since the box is
a non-critcal but RAID application, I'd be tempted to let the good HDC one
go on and see just how long it *does* last since it's not reporting any
hard errors.

The low power cycle count is one thing I'd attribute to the longevity of
the drives...nice stable temperature and power conditions, with a very
small number of head 'landings'.  Lots of on-off cycles is punishing to a
drive.

I've got a drive in one old Sun machine that's been going for over 15
years now...and for the last 5 it's main spindle bearings sound like a
threshing machine...but it's still going!  I'm going to let it run until
it dies...or I do.  I hope it goes first!
