Make Your Own Copy-Protected CD with Passive Protection

Step 1: Burn a regular audio CD

Start Nero Burning ROM and create a new Audio CD project. [View] Add the audio tracks that you want to include on your copy-protected disc. [View] When you're ready to record, click the Burn button on the toolbar. In the Burn tab, make sure "Finalize disc" is unchecked. [View] Insert a blank CD and click Burn. Be careful not to infringe any copyrights! For loads of great music that you can copy legally, visit Creative Commons.

Step 2: Add a data session to the CD

Start another Nero compilation, this time selecting the "CD-ROM ISO" project type. In the Multisession tab, make sure "Start Multisession disc" is selected; and in the ISO tab, make sure Data Mode is set to "Mode 2 / XA". [View] Add any files that you want to be accessible when the CD is used in a computer. You might include "bonus" content, such as album art and lyrics. [View] For a more professional effect, consider adding the installer for your favorite spyware application and creating an Autorun.inf file so it starts automatically. When you're finished, click the Burn toolbar button. Insert the audio CD you created in Step 1, and click Burn. [View] Nero should warn you that the disc you've inserted is not empty; click Yes to add your data files as a second session. [View]

At this point, you've created a CD that contains both audio tracks and data files. The data files you put on the CD should be visible in Windows Explorer (in My Computer, right click the CD icon and click Open) and the audio tracks should be rippable with your favorite audio player. To add passive copy protection, you'll need to modify the layout of the data on the disc so that the audio tracks are more difficult to access.

Step 3: Rip the CD as a CloneCD image file

Make sure the CD you just created is still in the drive and start CloneCD. Click the "Read to Image File" button. Select your drive and click Next. Choose "Multimedia Audio CD" and click Next. [View] Select an easy to find location for the image file and click OK to begin ripping.

Step 4: Modify the image file to add passive protection

The CloneCD image you created in step 3 actually consists of three files with names ending in .CCD, .IMG, and .SUB. The .CCD file describes the layout of the tracks and sessions on the CD. You'll edit this file to add the passive protection.

Start Windows Notepad and open the .CCD file. Modifying the file by hand would be tedious, so I've created an online application to help. Copy the entire contents of the file to the clipboard and paste it into this form, then click Upload. Copy the output from the web page and paste it back into Notepad, replacing the original file contents. [View] Save the file and exit Notepad.

Step 5: Burn the modified image to create a copy-protected CD

Insert a blank CD and start CloneCD again. Click the "Write From Image File" button. Select the image file you modified in step 4 and click next. Select your CD recorder and click Next. Select "Multimedia Audio CD" and click OK to begin burning. [View]

That's it! You've created your very own copy-protected CD.

Now it's time to test your disc. If everything worked, the files from the data session will be visible from My Computer, but the audio tracks will not appear in Windows Media Player, iTunes, and most other mainstream music players. The CD should play correctly in standalone CD players.
