Brasero CD-burning error - CD unusable

[Martin Wildam]

The latest 2 or 3 attempts (being on different kernels) burning a data CD always ended up a burning error and the CD was unusable. I cannot provide any more helpful info and hope the logfiles that have been collected automatically using "ubuntu-bug brasero" show something helpful.

I am using a Dell Latitude E-6530, currently on kernel 3.5.0-18-generic

Interestingly, it seems to happen with data-CDs but not with audio-CDs.

Hi,

there was a brasero bug fixed in the course of
  https://bugs.launchpad.net/ubuntu/+source/brasero/+bug/780117
which began by a different problem but collected several
reports about unmountable CD and DVD.
It hit data burning on-the-fly but not burning of pre-produced
ISO images or of CD audio.
I understand that Ubuntu is fixing it in some of its past
releases, too.

But you report "ended up a burning error".
The fixed bug did not produce error messages at write time.
Error messages at write time might indicate a problem between
drive and medium. (E.g. "Write error" is normally not the
fault of the burn software.) Success and failure can alternate
in such a case and thus create false impressions about the
cause of the failures.

Can you tell the exact error message ?
Best would be to make a run with logging enabled. (Don't ask me
where in the GUI to enable logging. I always use my own CLI
programs xorriso and cdrskin.)

Have a nice day :)

Thomas
