key2audio is really a crap thing but it’s not true that the cd becomes unreadable after a few scratches because this kind of protection affects the TOC (table of contents) and not the audio tracks. Cactus Data Shield cds are more vulnerable because the protection is “inside” the tracks. The quality of CDS cds is also affected but the quality of key2audio is not deteriored. It’s easy to make backup copies of key2audio. If the reader is not able to directly read the cd BUT it does not reject it you may have a chance to rip the cd the digital way using CDRWIN. Just rip it by selecting the “select sectors” option, file format “wave” (not automatic) and then put 0 in “sector selection start”. For “sector selection end” you have to put a very high value, for example 600000. Then start the extraction and wait till an error message comes. The error message say that unreadable sectors are found and that the copy process failed. It also gives a range of values of the sectors that were unreadable. Take the first value and substract 1 to it. Start the extraction again and this time it should work. Then open the wave file in an editor like cool edit and remove the initial 5-10 seconds crap. Separate the tracks and voila. If you want you may also rebuild cdtext informations (you have to rewrite). It’s easy, you have a backup copy for example for car use in less time. Try it. I own an old dvd reader from pioneer (DVD 303F SCSI) and this method always work, sometimes I’m also able to play key2audio cds in windows. No change to play or rip key2audio with my yamaha writer (CRW2100 SCSI) There is a math way to calculate the sectors values, i’m not sure but I think 1 minute are 75 sectors.
