I again carried out a small experiment (as a simple user as I am) and
precise,
or rather I correct, what was stated in a previous email.
Burning an ISO to a blank CD-RW (after: wodim dev=/dev/sr0 -v
blank=fast) won't work either:
This is brasero-session.log:

There seems to be involved a difference between Cinnamon of Debian
Testing and XFCE of Debian 10. While Mauro Sacchetto does not get an
unusable drive with Brasero and a blank CD-RW on Cinnamon, i get to
that problem after writing succeeded but before the checksum gets
verified by Brasero. (The CD verifies good in another drive by
comparing the MD5s of ISO image and CD.)
With non-blank CD-RW i experienced sometimes the problem already
after inserting it into the ASUS drive while Brasero is running.
Mauro Sacchetto did not report such an early problem.
