Re: solaris cdrecord BH08LS20 drive BD-R problems
Hi,
> Do I have to format new discs before using cdrecord?
Given the fact that cdrecord prefers Disk-at-Once
i would assume that it does not expect BD-R POW
formatting (pseudo overwriteabe) but rather SRM
(sequential recording). The MMC rules for SRM
burning are the same with and without formatting.
(But without it is about 2 times faster.)
So the problem seems rather to sit in your local
cdrecord's perception of your media.
Yours:
Cdrecord-ProDVD-ProBD-Clone 2.01.01a61 (sparc-sun-solaris2.10)

Mine (BD-R unused unformatted):

Do you get a different -minfo output from a
BD-R which never was involved in a failed
write attempt ?
Did you try BD-RE yet ?
Did you try to burn BD-R by help of growisofs ?
(Be aware that the BD-R disc used up to now
might already be spoiled. Best is to test with
an unused disc.)
(Sorry: I have no use for single session BD-R.
So i will not try now whether my local cdrecord
can burn my BD-R. I use own burning software
which has no SCSI transport adapter for Solaris
yet.)
It would be interesting to learn what you get
with command dvd+rw-mediainfo out of
dvd+rw-tools-7.1 (growisofs). The output refers
directly to SCSI/MMC inquiry commands and might
allow further insight into the media state.
I get:
