Others have already mentioned the "mediacheck" option, you could also verify the individual RPMs with 'rpm -K *.rpm' from the Redhat/RPMS directory. This obviously won't tell you if the whole CD is ok though. A simpler solution than 'dd' to making iso images and burn them to new CDs might be: $ cat /dev/cdrom > disk1.iso (no need to mount the CD) $ cdrecord -v --eject speed=X disk1.iso (assuming the drive is configured properly in /etc/cdrecord.conf) I've used this to make copies of 7.3 & 8.0 CD sets & I'll try the 'mediacheck' option with a couple of copies tomorrow. Warning! Creating the iso image in this fashion will likely hammer your system with *lots* of disk I/O, although it probably won't take all that long depending on the speed of the source drive, etc. I don't know about verifying the original md5sum, although you could make your own and check them before burning to cd: $ md5sum *.iso >> MD5SUMS $ md5sum -c MD5SUMS -Eric -- Eric Sisler <[EMAIL PROTECTED]> Library Applications Specialist Westminster Public Library Westminster, CO USA Linux - Don't fear the Penguin.
