My computer does not display or recognize all my drives. It will will not show drives above letter "F". My drives are, a: floppy, c: hard drive, d: cd burner, e: dvd/cd player, f: dvd burner, g: usb hard drive. Yet g: drive is listed under disk manager. I have tried changing a drive letter to H:, but no luck. I'm using xp with sp2.
