Mike is absolutely right. We also use the above mantioned enclosures (3 to be exact @1.2TB per) and I have to say to work like a charm. However with that said, they are hard drives and for that reason alone anything can go wrong. Regarding LaCie…I had purchased several units for a client in Isreal, ship him the units with projects loaded on them and one was dead within 45 days. Bad unit? Effects of Shipping? User abuse? Its hard to say. This is why we use a mix of storage solutions, including backing up material to DVD-ROM.
