a few people had more chance with single layer DVD+R for the 0800, worth a try.
On the ideas, to be honest yes (IMG:

You could also try to go back in firmware prior to firmguard, just to see if you drive is seen that way.
Also I am assuming here that, it is not seen at all, not just the letter not assigned to it. So in admin toot/computer mgmt/disk mgmt of windows it does not show.
is that the setup you used to first flash your drive??
