It took some work to figure out how to get everything working. Including some reading on the Apple discussion boards and this Reddit post.

Armed with the knowledge that Apple uses what it calls Volumes inside of a Container and auto-magically shares the available space between them. I understood what to do.

So I set about creating a drive with Partitions in the traditional sense. Meaning that there is no resizing or shared space.

The key for me was understanding the above dialog. Choosing Add Partition did exactly what I needed. Create two distinct drives without any magic resizing involved.

Was able to verify the configuration by going to Settings -> General -> Storage -> "All Volumes".

Success!

Happy Coding ;-)
