After my onetouch 'broke' I took it apart and the HD was fine, it was the other bits that made it an external HD that had gone wrong. So, i've now just got it as a hard drive in my PC. Makes me wonder what the point of the external drive is? The only thing I can think of is if my PSU blew, it might now take the HDD with it, whereas before it had it's own spower supply
Or your on a laptop and need more storage space or to move that data from one location to another?
