Situation: My most important external Hard drive is crashing my computers. It had my time machine backups and random files stored. I've tried it on my iMac and Macbook Pro. It may be worth noting I installed Parallels recently.
Does anyone have any ideas or solutions? I was about to open it up. The fact that it shuts the computers down makes me think it isn't necessarily a read/write failure?
