This is a terrific device. I am not sure what the other users are complaining about. I have had the drive for a few months now and it works great! Installation is very simple - almost any computer will recognize it as a new USB connection. It doesn't spin as fast as a Maxtor drive, however, for 320GB - this is exceptional value. I have transported the drive and used it on over 5 computers - each computer had no problems with reading and recognizing the device
