But you can... in Unix-like environments everything is a file! md5sum /dev/cdrom should get you there. You might need another device than /dev/cdrom depending on your setup, 'cat /etc/fstab' should show you which device is used for /mnt/cdrom (among all others). Common CDROM devices are: /dev/hdb - CDROM is slave on first IDE channel /dev/hdc - CDROM is master on second IDE channel /dev/hdd - CDROM is slave on second IDE channel /dev/scd0 - CDROM is first SCSI CDROM /dev/scd1 - CDROM is first SCSI CDROM (/dev/cdrom is set up to point to the first 'real' CDROM device found by the installer) This might be enough to give a 'feel' for the pattern. BTW I can think of a few "legitimate" ways to write perfectly fine CDs which would not give the same md5sum of their images... OTOH if the sums match you can be very sure that the contents are OK.
