SafeDisc 2 CloneCD Patch?

[Survivor]

Hi!
I've heared that a SD2 CCD Patch would exist. If this ist true, does somebody know where to get it? Or is there another way to COPY (not crack) Red Alert 2? It's said that Plextor writers can make working copies. Why can't CCD copy SD2? Someone said something about mixed up Mode1 and 2 tracks. Does somebody know more about that?

Kind regards
