wow - thanks for the quick responses. My computer is a laptop so I'm not sure about plugging it into the computer. But my guess too is the enclosure. Maybe I should get a new one first, put the hd into it and see what happens?
I have a 120G external hard drive in a Moving Star enclosure. All has been working fine until the other day when I was doing some work (long story) but accidently unplugged something on the hard drive while it was one and plugged into my computer. Was so wrapped up in what I was doing I think...
