It's because (as I know from some old articles) if you connect one device with high-speed, and second with lower speed onto the same cable, they will BOTH use the lower speed. And it may be problematic for some new HDD, to be as slow as CD is (using PIO, or UDMA-33) (although they all say about standards conformity etc.).
