That will generate a different sum if there are any padding sectors after the
iso on the cdr.
If so it may need:
dd if=/dev/hdd bs=2048 count=X |md5sum
where X is "No of 1k Blocks"/2 that you get from:
mount /dev/hdd somemountpoint && df
Some boxes, I have one such, don't like dd from a cdburner in which case:
readcd dev=/dev/hdd f=- sectors=0-X |md5sum
