Overview

SafeDisc is a protection format that places "corrupt" sectors near the beginning of a disc (usually in the 807 - 11920 sector range); however, these sectors can be found just about anywhere. The key to dumping SafeDisc images correctly is to make sure that the corrupted sectors are dumped properly. It is also critical to dump the disc at least two times using at least two different drives (the more, the better). If everything goes well, all of your checksums should match.

Methods

There are two solutions (at present) for dumping SafeDisc games: (1) CloneCD, and (2) CD Manipulator. Both tools have been tested extensively, and have proven to be highly dependable in most cases (when properly configured). It's generally advisable to dump protected discs using different software AND different drives whenever possible in order to ensure that a thorough dump has been performed. That said, feel free to use whichever tool suits you best! Use the following to guide to setup your software:

1. CloneCD
   • Create a custom profile (see link), and use it for all SafeDisc dumps.
   • You're all set! The software will handle the rest.
2. CD Manipulator
   • Select "Read from CD to Image File"
   • Select the applicable drive from the drop-down list
   • Select "Single-Session mode (high compatibility)" in the drop-down menu
   • Specify where the image (.CUE/.CDM) will be saved
   • Check "Extended Settings" and then check "Ignore Read Errors" and "Auto Detect Read Channel". Uncheck everything else.
   • Set your "Data" and "Audio" speeds to 4x-8x, depending on your drive's compatibility.
   • You're all set! The software will handle the rest.

Data-Only

1. Use BurnOut or ProtectionID to determine the SafeDisc version
2. Use either CloneCD or CD Manipulator to dump the disc.
3. Compare the dump checksums.
   • If they match...then great!
   • If they do not match...check your settings; try different drives; try different tools; ask the community.
4. Check the image in CDMage to get the SafeDisc error count (it's usually helpful to save the log).
5. You're now ready to submit your dump!

Mixed-Mode

Most SafeDisc titles are data-only. However, a few mixed-mode discs (data+audio) have been spotted in the wild. If your SafeDisc protected disc happens to contain audio tracks...it is CRITICAL that you dump the data portion of the image separately from the AUDIO tracks and then dump the AUDIO tracks in the normal way. This is because the suggested dumping software translates SafeDisc errors in a special way, and if any SafeDisc errors are present in the audio tracks they will need to be read "normally."

Additional Submission Data

Please include the following information with your SafeDisc dump submission in addition to the regular Submission Information:

1. Number of SafeDisc sectors
2. SafeDisc version
