I have had my WD 320gb for 2 years. It had been working perfectly fine until yesterday. My computer does not recognize it anymore. I have tried many solutions but it still would not work. When I plug the hard drive in, it does not show up in "My Computer". I go to "Disk Management", but it doesn't show up there either. The only thing that shows up when I plug it in is the "Safely Remove Hardware" thing. Please help me because I got a lot of important files in my hard drive.
