     aren't tested very well (on FreeBSD or DragonFly).  It's been
     a plague in FreeBSDland for over a decade, in fact.  The most
     recent code on FreeBSD might work a little better but for all
     intents and purposes the ATA/IDE chipset ABI has too many quirks
     to be dependable.

     The AHCI and SILI drivers are much better suited for error path
     handling.  Of course, using AHCI requires a chipset that is
     AHCI-capable.  Ultimately all new computers will have AHCI capable
     chipsets but it might be another year or two before the transition
     is complete.

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.
