Summary: Like the look of these drives but at the moment my second one just crapped out on me and i'm sending it in for a replacement. The first one worked for awhile. Maybe 7 months and then just stopped mounting. Tried zeroing it and some other ideas from Lacie but eventually just had to send it in to be repaired. They sent me a brand new one as a replacement and it only worked for a couple of months before the same problem started happening.
Summary: The LaCie Starck 1 TB External hard Drive is heavy and beautiful. I just couldn't get it to work. The first one I bought wouldn't show up on the desktop when mounted. I took it back to the store where I bought it. They tested it, said it was defective and traded it for a new one. When I installed that one, the software didn't. I took it back to the store, and they downloaded new software from the internet for it. That actually did work. Kinda.
Summary: Easy to set up on a mac. Seemed to work well, fast and quietly - at first. Then after a few days the power button would not turn the unit on straight away, taking 3 or more goes to do it, and even worse turning the thing off. So I have returned it. Shame, as I liked its good points: small and well made, lots of room and good price.
