I just did a test using the d8 command, and it seems to work (the drive led flashed and I did not get any error :-)) > (Btw., what's the `subcode' field for?) My documentation is very short. I got it from some FAQ a long time ago, and I losed the original text. Now I only have a printed sheet of paper with the following indications: special sub code selector 0 == normal 2352, other values are 01, 02, 03 I think this is also documented elsewhere because I added some manuscript notes: 1 -> audio data + 10 bytes Q-subcode+6 null bytes = 2368b; 2 ->audio data + all subcode data = 2448 bytes; 3-> all subcode data (P-W) only = 96 bytes > -- > cheers, J"org > joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE > Never trust an operating system you don't have sources for. ;-) Jean-Marc _____________________________________________________________________________ Jean-Marc Zucconi Observatoire de Besancon F 25010 Besancon cedex PGP Key: finger jmz@cabri.obs-besancon.fr =============================================================================
