When it goes into panic there is not much you can done. Pulling the power is your only option. You can still get 5400rpm drives. It could be a thermal problem during large transfers. I know the 1000 run 10 deg cooler than the 1100. The 1000 controlls between 95-135. On the 1100's 105-145. Also the way they are design, you need to cover the opening by the connectors, if you have the case off. Other wise it will not exhaust the heat. Once the temp reaches ~160deg it will start crashing. The 2200 does not have thermal control, the 2000v1 does not either. If you can wire the CPU fan so it will run 24/7. The cooler they run the better,

I noticed on my 4500 (with the 4 x 400gig Seagates) was having problems when I first set it up. After running SpinRite on them it improved. I have one drive in the set that has a buch of bad sectors and has seek problems. Not bad enough to signal the Smart parameter as a bad drive. When I do large transfers it shows up.
