Hitachi 6GB microdrive "Failed to move image"

Although C1Pro Mac ver.3.6.1 recognises that I have a CF card and launches it's file reader it \"Failed to move image!\" with each image shot on the card. I've formatted the card several times on the camera and tried to follow your directions to do so on my computer but this was not an option in Disc Utility that I'm aware of. I could erase the disc and reformat on the camera and although it does give me an MS-DOS file, I'm not at all sure that this process has achieved anything. I can manually move files but they are not renamed and processed in any manner. Please help me resolve this issue. There is nothing wrong with my card as it captures images well. I simply cannot import them with any speed and or elegance. Since I typically process some 200 images at once this is indeed a very serious problem.
