Unfortunately, Canon doesn't have a way to disable JPEG processing. Even if you are in RAW mode only (no JPEG), Canon still does a full round of heavy duty JPEG processing just so it can embed a 3 MB JPEG "preview" inside the raw file. I wish they would allow me to disable it, even if it meant a very slow image review, but they don't. Back in the good old days, Canon stored the preview separately, so that it didn't needless bloat the raw files. A guy can dream...
