Re: dvd+rw-tools: growisofs exit code
In response to Volker:-
I have been using PRINCO media for 3 years with extremely good results. So
have colleagues. People using Windoze software (Nero and the like) do seem
to have problems with this manufacturer: one can only speculate why.
I have never seen a failure in reading a Princo DRD-RW or DVD-R disc that
has been reported as successfully written. Very rarely, I have had burn
failures like the one that I posted. On each occasion, simply re-trying,
sometimes after reloading the media, has worked.
I am well aware that there are people who seem to have a great deal of
trouble with Princo media, but none of the mailings that I have seen have
inspired any confidence that these were from people with any understanding
of the technologies. They just abused the manufacturer rather than provided
any reasoned explanation.
It may be that there were some very poor batches, and that I have been
lucky with my discs. However, a relative who uses Windoze had trouble with
a pack of 50 DVD-RW discs, not from Princo. He sent many samples of these
"troublesome" discs, but dvd+rw-tools handled them flawlessly. No failures
at all, yet there were repeated and consistent failures with the Windows
software (Nero and Winbackup). And the drive was a PIONEER-105. Changing to
another media manufacturer, there were no problems.
However good is a manufacturer, there is still a chance of the occasional
defective disc. I want my script to notice and not blindly miss a 4.3 Gbyte
chunk out of a series of DVDs in a backup set. My backps use between 3 and
10 DVDs to do a backup, depending on the machine.
So just changing to another media manufacturer is no answer to my
particular wish for (near) certainty that when my backup script runs to
completion, I have a good and complete set of discs.
But thank you for the suggestion,
