BigBear Immich - USB HDD as image storage

Hi!

How can I mount an external USB hard drive as image storage in Immich on ZimaOS?

Something about this doesn’t quite fit:

In Immich, the internal memory is mapped. Sorry, I’m a total noob at this.

UPDATE:

Is this correct?I’m confused because it shows something different for storage. That’s the internal storage…the external USB storage is completely empty.

See the second image above.
