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. -tony
