Right heres one for the experts
A guy at work has a dvd burner out of an IBM PC, it's black (and looks a hundred times better than the standard LG one) anyway the system shows it up as a GSA-4040B (i.e. made by LG) and it had firmware A109 loaded.
Problem is it screwed one of my TDK 8x +r discs which are normally excellent discs.
I cannot find anything about A109 firmware anywhere. I've flashed it to A304 now and it works properly.
Where the hell does A109 come from? It doesn't even seem to be released. What is it supposed to do?
