Ouchers. Either your drive or your operating
system is severely challenged with a 18 MB DVD+R
which is not closed.
Let's hope it is only the os. :))

Indeed. It would mean you cannot reliably work
with mkisofs or genisoimage which read the old
ISO image info via the block device.

More hope will be with soon-to-come xorriso
which uses libburn for reading and thus
needs the block device only for tunneling
SCSI commands.
But if the drive is confused, then this
will hardly help.

One clumsy remedy could be to write as first
track at least one GB of dummy data to media.
How about this for the first track:
  cdrskin dev=/dev/scd0 -v tsize=1000m \
          -multi track_01.iso

(It is recommended to leave the -tao/-sao
decision to cdrskin)


Have a nice day :)
