Here are the results of the methods that were suggested for producing a
CD image.  They all seem to fail at the same place because the resulting
file is the same size.

	# dd if=/dev/cdrom of=/tmp/cd1.iso
	dd: /dev/cdrom: Input/output error
	1440+0 records in
	1440+0 records out
 
	# dd if=/dev/cdrom of=/tmp/cd2.iso bs=2k
	dd: /dev/cdrom: Input/output error
	360+0 records in
	360+0 records out
 
	# cp /dev/cdrom /tmp/cd3.iso
	cp: /dev/cdrom: Input/output error
 
	# ls -l /tmp/cd*
	-rw-------    1 root     root       737280 Sep 17 14:09 /tmp/cd1.iso
	-rw-------    1 root     root       737280 Sep 17 14:10 /tmp/cd2.iso
	-rw-------    1 root     root       737280 Sep 17 14:11 /tmp/cd3.iso

Thanks,
