I believe that is true. Otherwise, you can verify the physical disc in the same way you would verify the ISO file. For example, using the first disc on my pile of old discs: $ sha256sum -b Fedora-11-x86_64-Live-KDE.iso 4fdf952afb0d27887639140f6921ff58ba74f8d633b14414b095eb54b55df405 *Fedora-11-x86_64-Live-KDE.iso $ sha256sum -b /dev/cdrom 4fdf952afb0d27887639140f6921ff58ba74f8d633b14414b095eb54b55df405 */dev/cdrom I have tended to burn optical media using K3B, which has a "Verify written data" option that does much the same thing immediately after writing the disc.
