[Bug-xorriso] ISO-Disc not recognized

[sean loony]

Hi,

I have a 50GB BD-RE. It was previously probably written with growisofs 
and the -udf option or it was an raw image that was formated with 
mkfs.udf and then written, iirc. format is index 3, the most space
you can get, I didn't change that. Maybe it had previously a format
with spare area I don't know, but I put all discs in format without
sparearea if it has one.

Now I blanked this disk (-blank fast), wrote it ( streaming mode on ).
But then the automounter in linux says it cannot mount the udf file
system on this disk. With
 udiskctl mount -b /dev/... --filesystem-type iso9660 --options ro
it mounts it. But the volumename is 'disk' not the name I set when the 
disc was written.

It seems blank blanks not enough. On DVD+RWs I blank them allways with
 dd if=/dev/zero of=/dev/thedvdwriter bs=32k count=250
and that blows away any previous files system so that it is recognized 
as blank. But dd doesn't work on BD-REs it says its a ro device.

-blank fast should blank a few more sectors.
