Alright Ive got an external 160gb USB hard drive for my laptop and I let my friend transfer some files from it, instructing him not to leave it on all night because it could burn out, but he let his sister transfer some stuff and she left it on all night cuz shes a dumb bitch and now my computer doesnt recognize it... It turns on and everything but it just doesnt show up on the computer. Is there anything that can be done to fix this? or at least recover all my data on it?
