It's not the hard drive's temperature. Come on guys! Heat doesn't make three hard drives CRASH. They may make them hot, but not three of them crash. How do I know? Alas, I have proof!
I have 5 hard drives (160, 160, 120, 80, 20) with practically little to no airflow near them, and they all work fine. I've been running them for a while now (1+ years). None of them have ever messed up. My case temperature is approximately 85-100 degrees F, give or take during the time of day and season
I think the problem is a something deeper....
