It has always been a problem for Windows with CF cards reporting itself as Removable instead of Fixed. Sadly, CF cards reporting itself as Fixed is very hard to find.
The question has been raised a few times and I still haven't found an answer until I stumbled upon this video from dosdude1's channel about how to reprogram SM2236-based CF cards with the controller's MP tool.
I decided to give this a try and of all the cards I've attempted only a Toshiba 128GB CF card turned out to be using SM2236 (thus picked up by the tool). After reprogramming the card following the video's instructions, it now reports as Fixed and has SMART enabled. I did a F3 test just in case, and it passed without errors so the card is now working and ready to be used.
Just I'm not sure about other CF controllers (vendors and models). Is there a good place for documentations of known CF card controllers (and maybe supported NAND flash types)?
