A VCD is a Virtual CD-ROM. It is a small partition on the DL3 hard drive that appears and functions like an ordinary CD-ROM volume. It is read only and your host system recognizes it as a physical CD-ROM. The DL3 has a free utility which allows you to “burn” a standard ISO disk image up to 4GB in size to your VCD. Since the VCD is an exact mirror of your ISO drive image, the partition is not encrypted however it is only accessible after you have entered your password.
With the DL3, you have the option of enabling or disabling the VCD if you are logged in as the Administrator in the System options menu.
