The RAW data should be unchanged as, by definition, it is the RAW data collected from the sensor. Possibly the embedded preview are B&W (that's seems logical, but I wouldn't bet that they all are). And if you shoot JPEG, they don't have color, even in RAW+JPEG. > If I simply de-saturate a Raw (color) file am I really achieving the > correct B/W results or should I really be adjusting the ratios of RGB > also? That's a question left to the camera manufacturer or your own testing. Basically to have a B&W image you can just remove the chorminance information. But then you can also choose to use color filter and make a color more important than the other in term of luminance (like using colored filter when printing from film in a dark room). And that's the detail that may be specific to a camera or even its internal settings.
