Here is an Amiga mod for Sony 920 MPF z/121 floppy drives using in Akai S1000/S1100 samplers, tested by my friend Takis (Zombie).
This is what i came up with, i did see some schematics on a Czech site for the "Z" series but they did not work properly. I tested their fix using "The killing Game show" which took great delight in refusing to load the actual game with their fix. My fix works fine. I do not have X-copy so I'm unable to check that function, but i am pretty confident
that it will work fine.
The model i used is the Sony MPF 920 z/121 which is still on sale in stores (and also the z/131 which i have not
seen).
The mod itself is pretty easy, 2 wires, cutting a trace and moving a Zero ohm resistor. The low res pic is shown below and the hi-res pic (Link below) shows everything you need to know.
Here is the HD disable pic (This forces the drive to treat all inserted floppys as Double Density) AKA 880k Amiga discs.
As you can see we just need to short the two points on SW3.
Here is what is needed to be done in order for the A1200 case to close properly. All the marked area has to be removed or bent back in order for the top case to fit properly. It is really easy to do, just use a dremel or hacksaw blade on the left and right side and then use a pair of pliers to bend the metal up and back.
and here is if finished and fitted. Notice that the button had to be trimmed on the left side so it didn't interfere with the top portion of the case. The button is a little on the short side, but works ok. Overall the drive is a lot quieter than the POS that was in there originally. I'll probably fashion a button extension piece out of scrap plastic and glue.

Wrong mod as the Amiga is DD only and S1000/S1000 are DD&HD...
