Well getting the files off the stubborn hard drive didn't work with the external case. It didn't show any files when I turned it on. The external hard drive case works fine, I tested it with another hard drive. So I am going to try some data recovery software to try and get the files off. I don't know if the OS on this hard drive is so messed up it won't let me see the files or the hard drive is messed up beyond repair. If the file recovery software doesn't work I am going to see if I can reformat the hard drive and at least install Windows 7, that will tell me the hard drive is still good.
On the bright side of things, because of this problem I now have a new awesome video card and solid state hard drive. I like how fast they both are, especially the hard drive.
