This is only an 'academic' question, but how can I backup an audio CD protected by Cactus Data Shield? CDRWin and Nero cannot even read the CD, Alcohol 120% vers. 18.104.22.168 creates an image 2 GB large! The only thing I manage to do is to extract the traces with EAC (Exact Audio Copy, available at http://www.exactaudiocopy.de/). Every time the CD is loaded a number of traces equal to n (n<=N, N being the total nr. of traces that exist on CD)is seen. After some time, if you go on on ejecting/loading the CD, N traces are seen). After that, doing a WAV extraction (WAV button, present in EAC main page) is suggested. This because the last trax (only the last one, I think) is full with noise appended to the Nth song. Doing Tool_Process WAV you can remove the noise. This procedure is very good, but the resulting CD (if you burn the WAVs) is no more protected with Cactus Data Shield. How can you backup the full CD (i.e. with the protection included)?
