I just had a Seagate 3TB internal drive refuse to come up after a restart and all signs point to it being dead. I am thinking that, perhaps, 3TB is just a bit too unstable when I need a reliable drive. I've decided to go with a couple of 2TB in my MacPro 2.66 dual-core running 10.6.8. Can someone recommend a top quality 2TB internal HD? I've heard that Enterprise drives are expensive, but well worth the money. Is there any truth to that? I really need a drive with a great track record for reliability and I trust the people in these forums. Any suggestions or advice most appreciated. Thanks.
