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.
