I have two external USB-C M.2 SSDs. They are 2 Tb each. Both have the same issue -- They have approx. 1 TB of space missing.

See the first image below.

To clarify, I've never partitioned these drives. And they were showing at full capacity a few months ago.

When I try to run a repair, I get an error that reads:
"First Aid could not unmount one of the other volumes in the volume’s container. Click Done to continue."

I had read in an old post somewhere that sometimes Spotlight can run rampant and start dividing up an external drive, creating "ghost volumes." Maybe it is something like this?

I guess there's an invisible partition on there somewhere? How do I get rid of it without reformatting the disk? IS that possible? Also, why is this happening

THANK YOU!
