Hello, I wrote:

- make the CFA code check word 80 == 0 as a sanity check

That'll work unless we bump into a drive that does follow ATA in that matter.

... because it also does specify the CFA feature set (minus the exotic PIO/DMA modes). That's what you get for the closed standards. And yet there seem to be CF drives in the wild that follow neither... :-/

... or are just not supporting the CFA feature set -- see http://marc.info/?l=linux-ide&m=123263947330207 if you've missed that Kingston's wonder. :-/
