I still have mine, its been powered on a total of 10 hours. I tried to take it back but since i lost my receipt they pretty much told me to go to hell. So i backed some things up, unplugged it and put it in the closet but i did notice clicking before i put it away. These drives are bad and have a bad reputation.
On the other side theres a 5 year warranty so what im planning is just sitting on it until they finally make a drive worth buying then raising hell with customer service to get an RMA for the updated model.
May not ever happen but for $60 not a bad gamble IMO.
