The more option I have the better.
ie:
- BD-RE media: cdrskin can format it (when media is new/maiden), and has an
option (not default) to write BD-RE in a "quick" mode (don't recall
technical name, I think it's "streaming", it avoids defect management, I
always do md5sum checks anyway) even if BD-RE is formatted with spare/defect
management area. So writing with cdrskin takes half the time of cdrecord,
basically it burns at the nominal speed of BD-RE media.
- sometime cdrecord fails and cdrskin will succeed, I can't give you many
details, this is a log from last night backup on one of my systems (it's not
totally uptodate, so both cdrecord and cdrskin are not the latest versions)
I understand you'll rightly say it's a Linux issue, but I'm not a programmer
and cannot do anything to force Linux people to make things the right way, I
just need the best chance for the backup to complete ok.
