I recently noticed on my Compaq PIII laptop, one "phantom" drive. Turns out that it is the same old 8-speed USB Plextor I have connected thru a usb hub. It is seen in MyComputer as CD-drive(F) and as CD-RW drive(G).
It' quite annoying. Hm, the problem most possibly appeared when I finished burning with NERO, and when I clicked on DONE, Nero was stalling. So I went to "End task" in taskmanager, and ejected the cd from plextor.
Tried to look for answer with google, but no success. Tried system restore, still the same... I also have nero image drive active, and InCD and they sem to work fine.
