My friend's WD external recently died and we are trying to see if we can resurrect it. He had it connected to a mac and it started doing this thing where it would spin up, but not turn on and was no longer recognized at all by his mac. We opened it up took out the drive and I put it in my desktop PC. It is currently being recognized in my bios and disk management in win7, but does not come up in my computer/ I can't access the files. It also says in disk management that the drive has 100% free space. I'm guessing all this means it dead, but I was wondering if anyone had any suggestions?
