Use readcd (something like "readcd -c2scan dev=/dev/cdrom") for
checking the CD. md5sums sadly just aren't enough. :((

I strongly recommend the use of USB pens instead of CD-Rs if
possible, otherwise fall back to higher quality CDs which are known
to work fine with your CD burner. That's what we as grml developers
do as well. :)
