New version CDS 100 harder to bypass

XORFF has posted a thread in our Audio Forum that contains valuable information about the new version of Cactus Data Shield 100. It seems that now also the Plextor CD-writers, which are famous for there way of handling with audio-CD protections, can't defeat this one.

This 3rd CDS100-release is the first protection that cannot be bypassed with the help of a current Plextor Recorder. The PX-W1210TSi, 1210TA, 1610TA, 2410TA and most likely the 4012TA do not recognize the CD. The only reaction is a blinking drive LED. In opposite to that the old Plextor SCSI-CDROM drives are able to rip those discs. The Right Said Fred disc has been successfully ripped with a 4PlexPlus, 12/20Plex, UltraPlex32 and UltraPlex40. The old Teac CD-R50S SCSI-recorder is also capable of reading the corrupt disc by using CDRwin 4.0 and read sectorwise.

CDS100 V3 consists of 3 sessions and 99 tracks (the former versions only had 2).

Session 1 contains the audio-tracks, session 2 has a dummy-4-sec-audio-track and session 3 has dummy-data-tracks. The anti-Plextor-trick of this CDS100 could be defect sectors in the pre-gap-area (ref. to DOC.loc-protection). When reading the disc sectorwise with CDRwin and the old Teac you have to start reading at sector 5. Otherwise the program stucks. The sticker- or felt-pen-trick does not work because the recognizing-problem appears to be in the pre-gap.

As you can read, Plextor CD-ROM's have no problem with the protection. Also there are not many discs that contain this protection yet. But still, protections are getting harder to beat, that is for sure. Our thanks go to XORFF for this information. You can read and discuss the full thread at our forum.
