Interesting. Ok, then there is something interesting going on: The head 
was clean, the pack was clean and working (haven't tried it yet in the 
other RL02) and yet 1 second in there was a lot of debris on the leading 
edge of the head. Looks like it was taking off the top of the oxide 
layer on the disk as opposed to flying.
