If you're trying to simply make an ISO with the right number of sectors, you
need to use 'isoinfo' to avoid these kinds of end-of-disc problems.
Something like (yes I use this quite often):

[mdomsch@humbolt mdomsch]$ more ~/check_cds
#!/bin/sh

CD=0

while [ 1 ]; do
      CD=`expr $CD + 1`
      echo "Insert CD #$CD.  What shall I name it?"
      read CDNAME
      SIZE=`isoinfo -d -i /dev/cdrom | grep "Volume size is: " | awk '{print
$4}'`
      dd if=/dev/cdrom bs=2k count=$SIZE of=$CDNAME
      mount /mnt/cdrom
      ls -lR /mnt/cdrom
      umount /mnt/cdrom
done


Thanks,
Matt
