It actually is possible, but since we are not all programmers, someone has to make a utility to do the job. And here comes the problem, because nobody does. There have been pleanty of talks about this, some months ago. It's NECs fault actually and it lost me from a customer because of its behaviour. Like we say, what goes around, comes around.
Eitherway, I stopped looking for this, as I'm looking for a new drive. 4570 suchs and so does the 4571. BenQ will add me to its customers pretty soon now.
