Hmm... It sounds like you have everything right under control. The only thing I can chime in on is to triple-check to make sure you have the proper termination everywhere, etc... If you are running any external devices on the FastLane, I think there are termination blocks on the board that need to be removed.
If it's any consolation, I always thought the FastLane was really strange at discovering geometry, anynow. I had two identical hard drives (down to nearly identical serial numbers, exactly identical model numbers and production dates) that the FastLane detected with different geometry. The total free space worked out the same, but the number of heads and cylinders were different. Puzzled the heck out of me. Never did figure it why it did that.
