1e restore from time machine failed leaving 2 disks
When restoring from Time Machine from Catalina back to Mojave
the first time it failed (stopped with just the message failed).
The second time i used another restore point which was succeeded.
For some reason everything seems okay except that my main drive seems to be have 2 internal disks
which look the same (different activating point).
I suppose this is some leftover from the first failed restore point.
I could downsize one of the disks and the space came available for the second.
It does not look like a partition but i am not familiar with this on a Mac.
I tried disk EHBO with no luck.
How can i get rid of the obsolete disk?
(see attached screenshots, i renamed one disk to be able to distinguish them).
2 internal disks which should be one (both had the same name before i renamed).
Below the obsolete one
Below the correct one
