After i disabled SET STREAMING, i was able to write a thoroughly formatted
DVD+RW. But when i inserted one that was never written up to its end, the
attempt failed to (re-)start background formatting (Format Type = 26h):
FORMAT UNIT
04 11 00 00 00 00
To drive: 12b
00 02 00 08 ff ff ff ff 98 00 00 01
+++ sense data = F0 00 0B 00 00 00 00 0A 00 00 00 00 00 00 00 00 00 00
+++ key=B asc=00h ascq=00h ( 488 ms)
I cannot spot an occurence of this sense code in the qemu sources.
There are B 00 06 , B 29 07 , B 3E 01.
