The CF card is most likely formatted with SFS which needs a 020 CPU.
Correct, it was ordered as A1200 spec NOT A600.
As such I set it up with SFS.
Best thing to do is copy all the data off the drive in a 1200, then alter the filesystem in HDToolBox, then format and copy all data back.
EDIT:- If you return the just CF card to us with large letter stamp, we can reprep it for you.
