Hello. I have three Seagate Barracuda 7200.10 ST3320620AS's, and normally I've only seen the hard drive temps be around 32C. Suddenly, now they're all around 50C. I was wondering if this was bad, and if it was only because I put all the hard drives together nearby in one pc (instead of separate pc's). And I was also wondering what the highest temp these hard drives (or generally any hard drive) should go?
