Hi,
(Thank you for flying xorriso.)
The problem seems to be in growisofs.c function builtin_dd()
which inquires by
capacity = get_capacity (ioctl_handle);
before doing
pwrite64_method = poor_mans_setup (ioctl_handle,
outoff+tracksize);
which calls
bd_r_format (cmd);
This implies that there is probably no overwrite check for unformatted
BD-RE either. I assume it would pass the tests by capacity being 0.

After four years of daily BD burning I still have to see an example of
true benefits with Defect Management. If you really need it then it fails.
But Andy wants it that way. Including -use-the-force-luke=spare:none
as option to disable BD-R formatting.
(I believe that xorriso's defaults and its command -format as_needed
are slightly more easily and safely :))
Have a nice day :)
Thomas
