Cons: The short cord made me place it on top of my desk instead of on the floor. The first time I left it attached to the lap-top and dragged it onto a carpeted floor, it completely died. Now I have a quote for $1200 - $1700 to retrieve my data.
Summary: Just a nice heads up that I wish that I had found before I bought this drive. I bought two 2T Simple drives for my two year old iMac and they have this big problem : when the Mac goes into sleep mode the hard drive disconnects itself. I just called the Hitachi help line and they said that they were aware of this problem and the only solution is to either reboot the computer or turn the hard drive on and off. Don't buy this turkey.
Summary: Set up was completely effortless, and it seems to work as smoothly and as quickly as more expensive external drives I've purchased (some of which were really draggy for no reason I could ever figure out). I'm a designer, so this is my 5th or 6th backup drive, and I've owned WD and Seagate drives. 1 TB, cheap. I'm happy.
Summary: I have had this product for a few months and it worked fine until it fell on it's side, it did not fall off a table or chair merely onto it's side! Suddenly my computer could not read the parameters, it has a strange clicking sound and all my files have been lost! I have tried to format it but nothing happens. If I had bought this from ebuyer it would have still been under their return policy...
