Hi,
>> dvd+rw-format does not format my verbatim BD-R.
> What's its complaint ?
$ dvd+rw-format -ssa=268435456 /dev/sr0
* BD/DVD±RW/-RAM format utility by <appro@fy.chalmers.se>, version 7.1.
* 25.0GB BD media detected.
- illegal command-line option for this media.
- BD-R can be pre-formatted only once
The medium is left untouched (not anyhow modified).
It is also left untouched for:
$ dvd+rw-format /dev/sr0
* BD/DVD±RW/-RAM format utility by <appro@fy.chalmers.se>, version 7.1.
Thank you for the xorriso usage information,
xorriso -outdev /dev/sr0 -speed 4 -format by_size_23610m -as cdrecord -v image.udf
now does work well, but
xorriso -outdev /dev/sr0 -speed 2 -as cdrecord -v image.udf
does write with effective 4.1x speed?
My xorriso version is
$ xorriso --version
