To try it on another machine. Why I do this is to sort out if it's the machine or the USB drive.
What I do next depends on that test.

I have been using a WDC external hard drive for several years on a WIN XP SP2 Dell notebook system. Today when I plugged it into a USB port, I got a message "New hardware found - RC15". When I try to install it, I get a message, "Driver not found". I have not found anything meaningful on this problem anywhere. One suggestion was to delete the Windows/inf/infcache.1 file and let Windows recreate it. That did not help. I'm hoping someone here can help me access this very important external hard drive.
