There are also two circular trace pads below the corner of the drive  
closest to the power supply that can be cut through with a hobby knife  
to permanently set the drive to a number other than 8.  AFAIK there is  
no way to completely disable it since all the drive logic is on the  
same board.

Pictures of the traces are in my writeup on heat sinking the thing  
here.  For some reason sometimes the thumbnails don't load but if you  
click on the broken image icon it loads the full resolution version.
