I've got a 120G WD external HD that has a problem, caused by me, I'm sure. I unplugged it from the USB port during the shut-down procedure of my laptop. The laptop is running Windows XP by the way. Now I cannot access my external HD. I've downloaded diagnostic software from WD but to no avail. The computer no longer "sees" the HD. Anyone have any ideas on how to recover the data on this hard drive or who I could send it to, reasonably I hope, to recover the data on it?
