Firmware limitation as I understand it from the manual. 

"The firmware shipped with the CFFA card doesn t currently support
drives set to  Slave . If you set your drive to  Slave  you may be able
to leave it connected while you are using a CF card, but you will not be
able to access the drive until you set the drive back to  Master  and
remove the CF card."
