Please explain this question about Disk Utility in Monterey?

[blackxacto]

19,1 iMac, Monterey 12.0.1:

1. Shut down
2. Reboot holding Apple+Option+R
3. Chose an external disk to repair: Elite Toshiba MDXXX/Container disk5/"TimeBeast"
4. Why are time differences to repair an external ssd SO DIFFERENT between the Container disk5 and the enclosed data volume: "TimeBeast"
5. It took more than 4 times longer to repair the Container disk5, than the volume.

Why is DU so slow on a container and not the DATA?

Does the container contain any other volumes?
Did you compare the output of each (there's a log)?
Is the amount of time the same if you do the same procedure from macOS instead of Recovery?

The ssd is a data backup of my main hd, so I only created it. I don’t know what the system created originally when I formatted the external disk.

Think of one as verifying the table of contents of a book versus the other verifying all the individual chapters in the book. The second will take much longer.

 

[blackxacto]

I would think the data longer than the container

I would think the data longer than the container

That's why I asked you to check the log - to see if checking the container also checks the data.
