So I've got a brand new external hard drive enclosure, and I dropped in my PC's 320GB hard drive. I can verify that the hard drive works fine, since I've been using it for a while. But on OS X (and not windows) the it likes to just completely freeze. The HDD doesn't park or anything, but the activity light remains on and it won't transfer anything to or from the drive. It's REALLY annoying. I have a buddy who works at the Apple Store and says OS X is notorious for failing hard with USB hard drives, so any tips would be appreciated. Thanks!
