I am looking for a way to check I did burn my debian installer iso
properly.

IIRC, Debian installer provides a "check media CD" option, so you can use
that.

I am trying:

$ cmp /dev/cdrom debian-505-powerpc-netinst.iso

This works on CD-RW, but it fails on CD-R with the following:

cmp: /dev/cdrom: Input/output error

Has anyone seen this before ? How else could I check the CD-R is
actually properly burned ?

I think you could just:

cd /media/cdrom
md5sum -c md5sum.txt

Also, it seems to be a "checkiso" script that can be useful for this task.
