HELP!!! I have a 500gb external hard drive which, up until a few days ago, was working absolutely fine. When I would plug it in to my laptop the device was found under 'my computer'.but would not open. Instead when I tried to open it my computer froze and the 'not responding' message was shown, resulting in a forced close of my computer. Now when I attach the hard drive and open 'my computer' the hard drive does not show at all, but 'my computer' still shows the message 'not responding', resulting in a forced close. I've been on to a couple of forums already and tried the route of right clicking 'my computer', 'manage' and 'disk management'; but the hard drive does not appear there. I'm at a total loss what to do and would massively appreciate your help as I have backed up company data on to this hard drive. Thank you in advance!
