Not really an expert on what happens on cds but I belive it has something to do with the some extra nulls packing it out to the end of a 2048 block or something like that. In any case the actual cd generally has a different md5sum than the iso. One way: cat /dev/cdrom > test.iso md5sum test.iso md5sum original.iso Or do it file by file: mount /cdrom/ md5sum /cdrom/* | cut -d ' ' -f 1 > cdsums mount original.iso -r -t iso9660 -o loop /mnt md5sum /mnt/* | cut -d ' ' -f 1 > isosums diff cdsums isosums hth Bob -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
