i've been experiencing compatibility problems with FC4
cd iso's  recorded on one machine not passing the media
check on a second, so i just attached a yamaha cdrom rw
drive to the scsi bus on the second machine to try to
record the iso's there.  the drive works fine in the read
mode, but not in the write mode - i.e. cdrecord doesn't
find it.

though dmesg shows the drive on sr0, there is no /dev/sr0
nor does MAKEDEV know how to make one.  MAKEDEV sr makes
/dev/srripc, whatever that is.  not sure where to go from
here.  ops all done as root.  any suggestions?  system
outputs below.

ls -l /dev/sg0 procudes:

  crw-rw-rw-  1 root disk 21, 1 040223:1602 /dev/sg1

dmesg produces:
