    Hi Vegard,

    what exactly are you comparing with md5sum? I ran into similar problems
    when having an Iso image. When comparing the original Iso with the burnt
    CD, I got read/write errors, IIRC. The way around was to mount the CD,
    do a

    mount -o loop image.iso /mnt/loop

    and then do something like:

    cd /mnt/loop/
    find ./ -type f | sort | xargs -n 1 md5sum > ~/iso.md5sum
    cd /cdrom/
    find ./ -type f | sort | xargs -n 1 md5sum > ~/cdrom.md5sum
    diff ~/iso.md5sum ~/cdrom.md5sum

    Hth,
