Very good info.

The problem is here:

The failed command should tell about the disc status, including
the "Erasable" flag.
"Medium error" means that the drive does not like the medium.
(I.e. either drive or medium or both are bad.)

This causes libburn to tell libisoburn and xorriso that it is not
erasable. In xorriso/write_run.c :
 if(!isoburn_disc_erasable(drive)) {
   sprintf(xorriso->info_text, "Media is not of erasable type");
   Xorriso_msgs_submit(xorriso, 0, xorriso->info_text, 0, "FAILURE", 0);
   return 0;
 } 


You could get a source tarball, e.g.
  http://www.gnu.org/software/xorriso/xorriso-1.3.7.tar.gz
and throw out above five lines before running

  ./configure && make

  sudo xorriso/xorriso -outdev /dev/sr0 -blank all

Possibly there would arise more obstacles in libburn, before
actually a BLANK command gets sent to the drive.

Maybe dvd+rw-tools or cdrecord are more willing to do it.

  dvd+rw-format -blank=full /dev/sr0

  cdrecord -v dev=/dev/sr0 blank=all

But if reading the Table-of-content fails, then it is quite
probable that writing it will fail too.

So be prepared to try another medium (or drive).


Have a nice day :)
