|There are TWO hardware components that comprise an external hard drive. First is the enclosure itself, which is what you see in Device Manager. The second is the hard drive itself. |
What is the exact message you get when connecting the external drive?
With the external drive connected go into Disk Management in WinXP and see how the drive shows there. If it says it is RAW then you may be able to fix it by using a program called testdisk.
Post back before attempting to run testdisk.
