If you want the original md5sum back, then you need to peel it off just like
you layed it on...

dd bs=`isoinfo -i /dev/cdrom -d| grep "block size is" | awk -F": " '{print $2}'` if=/dev/cdrom count=`isoinfo -i /dev/cdrom -d |grep "Volume size"| awk -F": " '{print $2}'` | md5sum

If the md5sum matchs, substitute 'of=debian.iso' for the final pipe to md5sum.
