You got RITEKF1?! :eek: Didn't know those were in general availability already. May I ask why you're using 16x -R media on a drive rated for 4x -R?
I'm going to guess that the "F" means that they've moved on to a new dye type, and that would be why G04 and G05 won't work so well on it. If that's the case, then, unfortunately, I have no idea what strat would work for it. And seeing as how this disc type is extremely new, I would guess that not many other people have tried stuff with it.
Or it could just be that the disc is a piece of junk--I read about some early tests of the RITEKF1 on 16x drives like the NEC 3520 and BenQ 1640--all showed pretty bad results. This is Ritek, after all... :rolleyes:
