Fire up Disk Copy 2. Choose "File"--->"New"--->"Image from folder or volume" 3. Select the folder or volume you want to image 4. When the dialogue box comes up to ask what kind of image, specify DVD/CD master and AES-128 encryption; click "Save" 5. It will begin imaging. At the end of the process a dialogue box will pop up asking you for a password. TURN OFF add to keychain otherwise, anyone logged into your computer won't have to provide a password). 6. It will whirl some more and you will end up with a .dmg file that cannot be opened by anyone not knowing the password. That should do it. Charles Pearce (charlesp at ksu.edu)
