Emulated drives, or "virtual" drives, allow you to mount disc "images." For instance, you can copy a game or DVD movie to your hard drive as an image, then rather than have to insert the physical disc, you "mount" the image in your emulated drive. Emulated drives are automatically created when you install a CD/DVD burning program. You can remove an emulated drive by uninstalling it.
