If i get the code of dvd+rw-format.cpp 0.7.1 right
then you are not supposed to use option -ssa together with
profile 0x41. You are supposed to use option -force.

At other spots in the code i find traces that ssa is well
expected, though. Your code change should have had a chance
for success.

This does not look as if it was from dvd+tools but
rather from the kernel. Do you see that in a log file
or does it appear with the format run on terminal ?

Such an occasion would occur if the FORMAT command was
sent with IMMED bit for asynchronous work. A TEST UNIT READY
command which is used to watch progress then delivers
the error message of the asynchronous FORMAT.

As far as i can see the format descriptor gets the
right format type 0x32 for BD-R.


Can it be that the BD-R was already treated with
a format command previously ?
MMC-5 4.5.3.5 "BD-R Recording Models" says
" Once the recording mode has been established,
  it is not changeable."


Have a nice day :)
