Hi, Maybe someone could hit me with the clue stick. Please. I have generated a data disc, comprised of audio files, using; 'mkisofs -o $FILE.iso $FILE | cdrecord -v fs=6m speed=4 dev=0,6,0 /home/tmp/$FILE.iso'. When these disks are inserted into the CD drives on Macintosh computers, they either fail to be recognized immediately or they'll be partially read but ultimately fail. Could someone please give me a clue as to what I need to do to produce a data disk/file system that Macintosh computers can read. Preferably using mkisofs and cdrecord.
