[Pkg-opt-media-team] Bug#713016: dvd+rw-tools: Burning to previously blank BD-R ends by error message "CLOSE SESSION failed"

[Thomas Schmitt]

Package: dvd+rw-tools
Version: 7.1-6
Severity: normal
Tags: upstream patch


Hi,

it is a long standing bug of growisofs to throw an error at
the end of a burn run to previously blank BD-R media:
 
 :-[ CLOSE SESSION failed with SK=5h/INVALID FIELD IN CDB]: Input/output error

I don't see this reported as fixed in
  http://ftp-master.metadata.debian.org/changelogs//main/d/dvd+rw-tools/dvd+rw-tools_7.1-10_changelog
so i assume it is still present. (Experiments would be expensive.)


Being a competitor and a disciple of dvd+rw-tools i recently
re-read the 5 year old diagnosis of Andy Polyakov
  http://lists.debian.org/cdwrite/2008/07/msg00092.html
and developed a theory
  http://lists.alioth.debian.org/pipermail/debburn-devel/2013-June/000924.html
which leads to this tiny patch:

The patch is now confirmed to silence the error message.

growisofs users may thank Frank Griffin for bothering to test it.


Have a nice day :)
