All, I've heard that physical damage can be done to the heads and/or servo tracks of voice coil drives if the +12V power rail is noisy. I think the problem has to do with the heads incorrectly loading or unloading. How could the heads crash (or the servo tracks get damaged) through incorrect loading or unloading of the heads; and how could a noisy +12V power rail cause the heads to load or unload incorrectly? Thanks all. David Newall, 16:32:56.04, Tuesday, 1991 Phone: +61 8 344 2008 "Life is uncertain: Eat dessert first" E-mail: xtdn@lux.sait.edu.au

Hmm, this may explain why I have heard my two hard drives unload and load again at the same time. I may buy the Silencer 200 from PC Power & Cooling. Does anyone have experience with that model, or PCP&C in general? The fan is supposed to be very quiet. Anybody using one? Thanks. -- Chia-Chi Chao chao@cs.ucla.edu ..!ucbvax!cs.ucla.edu!chao
