Yes, and don't do it!

In every fixed/removeable drive I have worked on (OK, never an RC25, but...) 
the heads for both the fixed and removeable disks are on the same positioner
carriage. With the result that if you load the heads without a removeable 
cartridge in place, those heads will touch each other, which is a good 
way to ruin them.
