I have the same problem on my ferrari 3400lmi. mobmeter reports idle temps of 49~50 C and op to 65 C under load. I run smart tools and I know the hdd did give CRC errors when at the gottest. I know my HDD will die under this stress. I've changed my hdd to one that consumes less power. TOSHIBA MK1032GAX, 5400 rpm. It's faster, low cost, and a little cooler (not much).I'm looking to buy a notebook cooler, but for the time being, I'm running laptop-mode under Linux and even without spinning down the hard drive at all, the idle temperature lowers by about 3~5 degrees because all of the writes are done at once.
