I decided to return my LaCie 1TB drive. It worked okay, but I discovered after that it is actually two 500 GB disks. It doesn't say that anywhere on the box though. It has a noisy fan that is constantly starting and stopping - very annoying for a PVR.
I picked up the Western Digital My Book 1TB drive. It's a single disk with no fan, so it's much quieter. It formatted out ok, and seems to work. I'll give you my opinion after I've done more with it.
