It was working till recently when I did a reformat on my computer and now it no longer wants to be detected by my computer. My operating system is Windows XP. Its not in Disk Management and not in device manager. There is an Unknown thing in device manager under Other Devices which I think might be it.

Any suggestions? I can feel the hard drive spin up and I've tried another USB wire to connect to computer so that rules that out. Drive appears to be working fine but just won't detect by computer.
