I don't know much about SATA or PATA, but power saving modes shouldn't
normally be needed with desktop/server HD. Spinning them down isn't
recommended since desktop disks usually have a limited lifetime in
terms of spin-downs (although I've heard some disks like to the head to
be parked once a week or so for lubbing reasons).

Anyway, more to the point, I think you should check your fan. In such a
setup you may need an extra fan for the disks or the case. (could be the
cpu is running very warm or the case isn't cooled enough.

Another thing that can be hard on the disks is power surges. Make sure
you have a good PSU in there and a UPS can also be a good idea if you
don't have one.
