Absolutely correct, and which is why debugging an IDE-port in unknown state with a CF-card you don't know works with a driver you haven't tested with the CF-card in question on a working machine is not a good idea If something doesn't work (OP was lucky with his card here!) you just don't know where the problem is - CF-card that does not work with Falcon hardware, a driver that does not work with this CF-card or (in this case) a suspected broken IDE-port.
Personally I've given up CF-cards years ago. The only Atari I have now with a CF-card is my Milan, but the Milan has a different IDE port and is much more forgiving. I'm using IDE->SD adapters in all other IDE-equipped Ataris (and other retro machines).
