I've started adding so form of cooling to all of my hard drives and I've
not lost one since (and I used to lose MANY).  Many people underestimate
the effect that heat has on components.

As someone mentioned earlier in the thread, a taxed power supply will also
cause problems.  I've solved several strange system instability problems
by swapping out the power supply for a substantially larger one.
