There are embedded MD5 checksums, sometimes 20 of them per .iso. See /usr/bin/implantisomd5. Watch messages from /usr/bin/livecd-iso-to-disk. The drive+system which burned the DVD/CD might be different from the drive+system which is reading the DVD/CD at install time. Even on the same system, some drives use a different transducer for reading than for burning. Temperature, humidity, electrical supply irregularities, etc., can affect data integrity. > If not, is it possible to perform this media check immediately after > having burned the DVD (means: can I start the media check from that > freshly burned DVD?) /usr/bin/checkisomd5 -- -- devel mailing list devel@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/devel
