Does that previous session mount ?

What (error) messages do you get from:

  dd if=/dev/sr0 bs=2048 count=1 skip=1273136 of=/dev/null

Did you eject and load the media after writing ?

Is hald running on your system and willing
to automount readable media in that drive ?

Your Linux must be more ill than mine.
Mine is neatly and reproducibly ill.

What is not ill on my system is xorriso.
Did you try it meanwhile ?


Both problem reports seem to be related with
block device buffered i/o after expanding the
content of the media.
xorriso does not do such i/o.

A test run for only checking readability of
the directory tree would be:

 $ xorriso -indev /dev/sr0 -dus '/*'
 xorriso 0.1.0 : RockRidge filesystem manipulator, libburnia project.
 ...
 xorriso : UPDATE : 41941 nodes read in 13 seconds
 Drive current: -indev '/dev/sr0'
 Media current: DVD+RW
 Media status : is written , is appendable
 Media summary: 1 session, 720130 data blocks, 1407m

Have a nice day :)
