The problem is that we need to get information from the
_failing_ system and this information is rejected from Gregoire.

I did create a non-closed track some time agi and it did definitely
look different that this one.

In case of a non-closed track, cdrecord does not show another session.

One hint that the drive or media is confused/defective is that the next writable

in between.
