Thanks to all who have commented.

I will keep digging and see if I can atlease see where the ata drive is 
getting these errors. And if I am real lucky find a way to make my card 
play nicer with DragonFly. Well until I corrupt my drive ;-)

I was going to go out and get a new card, but maybe this will keep me on 
track to see if I can make it a bit better.
