It wouldn't leak, and I've never really understood why standard ATAPI drives don't allow access to the raw data. As you say, that sort of tool would have quite a number of applications besides piracy. For example, taking MP3 backups of my CD's, I already would have needed error concealment, a feature CD-ROM's do not implement when ripping audio. You can't implement that well without knowing where the error correction step failed, and that data isn't easily available. Also, I've always been fascinated by the fact that there's really no reason to follow the CD specs beyond 8/14 modulation other than compatibility. A writing drive capable of working at such a low level could be used to experiment with new encodings beyond what standard CD's can do -- say, substituting CIRC with RSBC and gaining some extra room on the disc, getting rid of the subchannels, a more intelligent coding of disc addresses... Breaking compatibility wouldn't be too useful, but it sure would be fun. Now you simply can't do it. -- Sampo Syreeni, aka decoy - mailto:[EMAIL PROTECTED], tel:+358-50-5756111 student/math+cs/helsinki university, http://www.iki.fi/~decoy/front openpgp: 050985C2/025E D175 ABE5 027C 9494 EEB0 E090 8BA9 0509 85C2
