Provided some program has the required information on how to do it. (It's usually a lot easier to get this kind of information from vendors if your name is mickeysoft, than it is if your name is just Myers or Wunsch only.) Also, you don't know about the actual quality of the read operation. You will know it after the 10th copy however. ;-) > Am I depending on drive-specific application-level code, much as the worm > driver only supports a limited set of CDR devices? Yes, it is. Each drive has its own set of commands. There seem to be a few main lines the vendors have chosen though (some mode page tweaking, followed by a regular READ(12) is one, issuing a READ(12) with 0x20 added to the command byte another one). I haven't looked into the SCSI-3 docs yet though, maybe it's indeed standardized again there. > >Depends on the drive.

RTFdoc. :) You'll be surprised to not find very much mention of these details in the docs either. Anyway, after at most one wrong CD-R, you should normally know... -- 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. ;-)
