It was working fine one minute, then i hibernated and when i switched on my computer again, the hard drive didn't show though the lite comes on and everything but my computer won't detect it. I've tried it on other computers and it's the same thing. I've tried The Disk management option but the drive doesn't show in disk management either. Someone should please help! am going nuts here as this is the 2nd hard drive am buying this month. Please don't ignore, if you have any ideas, please help...I have all my work on the drive and i can't work without one.
