Well, I checked the back of some 9153/9154 drives we have.  The documented
switch isnt there like TFM says it is.  (Should have looked closer before
my post right?)

Suggestions:
1) remove screws and pull out interface board to see if the switch is
   on it and just not accessable from the outside.  Use ESD precautions
   naturally.
2) try formatting using the unit and volume numbers.  maybe those are the
   keys now instead of the switch.  did you use unit #0, vol #0?
3) take the top off the drive and look in there for a board with a bcd on it.
   (Getting dangerous now right?  :-)  There could be some interesting
	jumpers too.  (No I havent torn apart my drives to verify this either.
	Have had others apart though and the jumpers are quite interesting)

I recommend #1 and #2 be tried.  #3 only if you have experience in the guts
of the hardware and know what you can get away with.  Write down the original
state of ALL switches and jumpers changed.  At least then you can get the
thing working the way it did when you started.  (No, you wont remember the 
settings later.  Later is always longer than you thought and by then so 
much will have been tried that all the positions seem reasonable.  
But then again, I was working on DEC boards :-))

Good luck....(No, I dont make a habit of using basic but I've read about
those partitions you're trying to deal with).
