This is not the same state as with the DVD+R DL which you initially
reported.

It appears that the old DVD took one valid session (by growisofs ?)
and only afterwards fell victim to wodim.

A run with -V -vvv instead of only -v might bring more insight about
the actual SCSI mistake that is made by wodim.
It is pure curiosity of mine, though.
As far as a user is concerned, the answer is found meanwhile.
If you had media with valuable data that were spoiled by wodim then
we could make experiments to fill and close the open track. Then we
could add another ISO session which would make the files in the
old valid sessions accessible again.

I meant the DVD written by cdrskin.
I understand it is mountable and dmesg only reports:

But this does not necessarily mean that the data files are readable.
Especially with DVD+R DL you have to expect unreadable blocks.
This would not be the fault of the burn program but of drive and
media.
Have a nice day :)
