[Coco] CF Card Question

[Luis Antoniosi (CoCoDemus)]

my experience tells me each CF card has a different IDE emulation. I have a
card that only worked after being raw copied using Active Disk Image (it's
30 dial trial so you can test it).

Sure they are true sandisks ? are they equal in color and shape too ?
