Hello,
well maybe my memory has blank spots.
I have two CDC Lark Disk modules I would like to revive, they are in good
shape, but only one has a cartridge included, and they are not identical.
Not sure if the other one could be employed without cartridge.
I never found a manual with exact model correspondence, I found years ago a
manual for very similar drives.
IIRC there was a sort of adapter board between SMD and (xxx blank spot)
interface. There was a description of the interface, it was really similar
to SMD, but wasn't SMD...
Maybe I should check again the Lark model number.

Oddly enough I have a 9457 Lark out in the shed. The trick is the SMD to
whatever it is connection is made in the power supply box, there is a
ribbon cable going from the box to up to two drives and an SMD interface
on the other side. Do you have the power supply?

I could probably lend it out, as I have a hacked copy of RSX11M on it.
First I have to find the controller/power supply. Will check around next
time I'm up in the attic.

I've been looking for one for a while to try to recover an early Sun Unix
if you don't have a need for it.

The ones I've seen were 9457, but there was also a 9455 which had a wider
track pitch resulting in it having roughly 1/3 the tracks and 1/3 the
capacity of the 9457.

LDI, Lark Device Interface. Not really all that similar to SMD. CDC offered
an SMD-to-LDI adapter.
Maybe I should check again the Lark model number.
