(and yes cdrom and dvd both point to sr0) The kernel often copies a bit more data that was requested from a CD / DVD (I don't understand why, but I don't think dd is a workaround). What I do is just compare the CD / DVD with the original file with `cmp dev/dvd my.iso` and I usually get an error like "EOF on my.iso", which means that all the data in the original file matches the DVD. -- ____________________________________________________________________ TonyN.:' <mailto:tonynelson@xxxxxxxxxxxxxxxxx> ' <http://www.georgeanelson.com/> -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
