Disk Utility shows the SSD structure as:
Top level: JMicron Generic Media
Second level down: Container Disk
Third level down: My Extra Pix
First Aid runs and returns clean reports on the top and third
levels. But running First Aid on the second level Container Disk
returns an error message:
“The repair cannot be performed because one or more volumes are
mounted. : (-69566) Operation failed.”
If I manually unmount the Container Disk using Unmount on the menu
bar, First Aid runs and returns a clean report.
Upon exiting Disk Utility, the drive is no longer visible in Finder
until unplugged/re-plugged at which point it is usable again
Running Disk Utility again after re-plugging, the same Mounted error
repeats. Repeated entire sequence several times. Same deal.
Problem? If yes- ideas to fix?
That's expected behavior. The volume needs to be unmounted to be
examined properly is all.
Yeah, but what I'm not understanding is why DU/FA doesn't auto-unmount
this disk prior to running the scan as it does with every drive.
It probably tries, but some process is busy using it. For instance,
often Spotlight will be indexing a drive and it will fail to unmount as
a result.

That was the likely culprit. It's running fine now!

How did you tell Spotlight to stop indexing so you could unmount?
