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,
