I tried to format it in win7 in a program called SDFormater. When I now put this in my A1200 the icon "CF0:NDOS" comes up.
So then there is something with the fat read on my A1200.
Clues. ?
PS. Card is a verbatim (2GB)
Did you actually try and format it on the amiga, when it came up as ndos?
If it still doesnt format it, then it will more than likely not be compatible.

Your posting that yours works fine, but your using USB. Not PCMCIA.
They are completely different and will work differently with different cards.
