I was not having this particular problem, but I had two 300Gb drives that i
was using as a raid 1 mirror setup.  I decommissioned that computer and
tried to repurpose the disks.  it seemed they still had some affinity for
the raid setup, and I was getting a lot of strange errors.

I can't find my notes on the exact situation, but, I believe I had to reset
up the raid 1 and delete the array that way.  I know I reformatted and may
have tried deleting the partition table and starting over from scratch.
