This is because of the buggy mode used to test if a given mode is supported or not. Quote from mmc specs: >>> 13.11.3.7 Write Parameters Mode Page .... The values in this Page do not necessarily reflect the status on a given medium. They will be used as applicable when a write operation occurs. If any parameters have values incompatible with the current medium, the Logical Unit shall generate a CHECK CONDITION Status, 5/64/00 ILLEGAL MODE FOR THIS TRACK when a write is attempted. >>> So the drive reports that mode even if the mode is not supported for the media inside. But we need only those modes that are supported for the media inside. Anyway, this does not answer to my question about packet and TAO. Is it true that if TAO is not supported and packet is, the cdrecord will refuse to use packet with the error "drive does not support TAO recording" ? I think so. Is just that all CD writers that support packet support TAO as well. This is not true for DVD. mache -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
