Since 2.4.19-pre8 cdrecord does not work anymore. It worked with -pre6, -pre7 i've missed, don't know about this one. Maybe i'll try it after this mail.

Christian,
What does the output of "cat /proc/scsi/sg/*" look like?
Cdrecord should see your plextor writer both as /dev/scd0 and /dev/sg0 (assuming you don't have any other scsi devices). Cdrecord goes on to scan the parallel generic devices (i.e. /dev/pg*) if it doesn't find anything suitable on its /dev/sg* scan.
Your post doesn't supply any information that would link this problem with the sym53c8xxx driver. If there is some problem then there will be some "noise" in the /var/log/messages file [typically showing multiple scsi bus resets].
BTW The "-vv" switch (and/or "-VV") on cdrecord will yield more debug information. strace may also be useful.

Sorry, was my fault. Lost CONFIG_CHR_DEV_SG during make oldconfig.
Anyway, thanks for your reply. It helped to find the problem...
