You can burn arbitrary data to a cd. The question is - how do you then get it back? If you burn one file per track, you're limited to the 99 track devices for reading them, and you have to dd them off with an odd blocksize. If you burn a tar file or something similar, you've still got the dd problem. The easiest way to deal with data on the CD is to burn a file system and then mount it to read the data back. Since iso 9660 file systems were designed for CDs, that's probably the best one to use. http://www.mired.org/consulting.html Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
