Not a problem with this product at all, Does exactly what is stated. For those using Mac, its a great drive for time machine and only takes a second to wake from sleeping (for such things as listening to music stored on it). I even dropped it once when transferring it but it seems to be sturdy enough to take it... although I wouldn't recommend testing this!
