Bad disks that don't burn correctly are often the result of downloads even after rsync has been used. I was able to get disc1 and disc2 to burn properly consistently but never did get disc3 or disc4 to burn without errors and I used an automated script to do the burns myself I had rolled. If all you can get good from the site is fedora-core-1 yarrow I don't advise attempting an upgrade from that version to current. I tried that and got four programs in unresolveable dependency chains so I decide to try installing what disks I can without running into the error again on disc 3. I figured I could make an initrd at the error condition; then reboot, then later do yum install *. Wrong. I couldn't get the ethernet up and connected on the internet. The fedora installation doesn't mark a package as a needed install when it encounters a disk error, it just hangs on the error program and offers no means to skip a defective program and go onto another program and mark the error program yum could take a script once connection were established and download the missing packages.
