I have a Western Digital 160GB external hard drive that connects via usb port. Recently when I connect the external hard drive to my laptop (Dell Latitude D505 with Windows XP) it no longer starts automatically. The unit does power up and come on, it just doesn't show up under "My computer" as a drive that I can access (although it does show up under Device Manager as one of the disk drives).
I've run diagnostics on it and it says it is working properly and I even hooked it up to a friends computer and it works fine so it's not a problem with the hard drive itself. This problem started over the weekend after my son loaded a Creative Zen Stone mp3 player software and connected that to my laptop. After that it stopped recognizing my external hard drive. Any suggestions? Thanks so much.
