In short, I would not buy again this disk. On my PC, the disk (USB 3.0 port) always disappears after a certain time from the file explorer and can be persuaded to work only through brief power interruption the drive again. About USB 2.0 angschlossen this error shows too, but far less frequently. Since I use the plate essentially only for backups, I can live with necessity. If you want to keep the disk permanently in the system in order to reproach than permanently available data grave, should look for another plate out or catch up a NAS. Since the money is definitely better spent. Think of Contoller that disk is simply qualitative waste.
