I am not familiar with 22Disk. Can you image each side as a separate
image? That should make it possible to read both of them.

We are trying to read some floppy disk used on a 1981 Italian Z80 machine
with CP / M.
The problem is that the firmware selects face A of the floppy as DRIVE
A and
face B of the same floppy as Drive B.
We saved an image with IMD and we know that the geometry of face A is IBM
3740 26x128x77 tracks.
By inserting this data into the 22DISK definition file we can
successfully
extract the CP / M files from A side.
How should we configure 22disk to be able to do the same thing on the
B side
of the same floppy disk?
Inserting Side 2 in the definition table is not enough ....
