I have mostly used CMD CQD-220/TM controllers. As far as I remember
they do not have an RA drive emulation option.
I also have some of the newer CMD CQD-220A/E controllers (the 220A/E
being Either MSCP or TMSCP but not both at the same time, while the
220A/TM can be both MSCP and TMSCP at the same time). I'll see if I
can find some time today to take a look at the RA drive emulation
option using a CMD CQD-220A/E controller, and see exactly what it
reports for MSCP drive geometry.
