Sorry, My IDE CF Writer comes up as ad2.
So I install the CF with the Golden image and use DD to make a copy of that
image. I then use DD to copy the image from hard drive to additional CF
drives.

Problem was solved....

umount /mnt #make sure it is NOT mounted
dd if=/dev/ad2 of=/cf.out #Stores image from CF to file

dd if=/cf.out of=/dev/ad2 #Stores image from file to CF

Works fine now, I guess using ad2s1 was only getting the first partition.
