Hi,
Use HDtoolBox, see if it recognizes your CF card, if it does then set it up like a regular hard drive.
BUT WAIT
Are you using a PCMIA slot or an IDE hard drive to CF adapter?
If you are using the Easy ADF transfer kit, RTFI, read the forgotten instructions. (thought I was going to say something else didn't you).
Anyway I have the easyadf transfer kit in my A1200, but it has been so long since I have had it on, that I am going to have to RTFI myself.
Anyway I believe you have to format the CF with an instruction on the easyADF, I will have to hook up my A1200 and refresh the old noggin.
Don't know if I have been any help, but I do know I have been more help then the guy who wears a hard hat at Amiga Org. Somehow someone has to teach him how to write.
