To my own experience, DVD+R DL are the first media to fail when the
DVD laser begins to go blind. Unformatted DVD-RW are next.

xorriso -outdev /dev/srX -list_speeds
shows what the drive is offering for the loaded medium.
The results differ from drive to drive.

It would be for the sake of science. :))
For example make a backup of your most prescious data:
xorriso -abort_on FATAL \
-for_backup -disk_dev_ino on \
-assert_volid 'BACKUP_*' \
-dev /dev/sr0 \
-volid BACKUP_"$(date '+%Y_%m_%d_%H%M%S')" \
-not_leaf '*.o' -not_leaf '*.swp' \
-update_r /directory/on/hard/disk /path/in/ISO \
... \
... more -update_r commands for more directory trees ... \
... \
-stream_recording on \
-commit -toc -check_md5 FAILURE -- -eject all
This run will write the backup at high speed and checkread the
data when everything is written. So failure should become obvious.
(Note: The sequence of arguments matters much here.)
If you put this xorriso run into a script and if the BD-R has space left
after a successful first burn run, then you may repeat the script run
some time later to update the BD-R by the changed file content and a
new directory tree.
So hopefully the medium is not totally wasted.
Have a nice day :)
