Thanks in advance to all who reply. I have a 20 GB, Western Digital hard drive which I used as a back up hard drive. I had a Dell and used it with that computer. The dell broke and I built myself a new computer. I really need to get the files off of that hard drive but everything I have tried doesn't work. I have tried setting different jumper settings and different cables, even different computers. Any help would be greatly appreciated. I will provide more details if needed.
