I had a disk two years ago that caused FBSD to spew the same nonsense.
I downloaded FreeDOS <http://www.freedos.org/>, created a CD then
proceeded to removed all of the partition information from the disk. I
then recreated the partition format I wanted, rebooted and formatted
the drive. Now, when I installed FBSD there were no error messages. I
don't know if that will help you or not.
