Disk utility hangs repartitioning external USB-C SSD

I have an external USB-C SSD that I am trying to set up to be a bootable backup (using ChronoSync).


To do so, I am trying to repartition the drive. But the Disk Utility appears to have hung. Here is what I have seen for more than an hour:


This is my third time trying this. First I tried it and it hung. I restarted. Same thing. Hard rebooted. Still the same. Any suggestions? Anything I should look for in the console? I don't see anything obvious, but there's a lot of stuff in there.


P.S. this is a very large drive, so I suppose it could be just taking a long time. But more than an hour seems really long.

Thank you very much! It does seem that the issue was the size of the drive. It took more than two hours to finish the partitioning operation, but it did terminate successfully.

It would be nice if the UI didn't "freeze," but instead gave some indication that progress was being made...


Thanks for your update.
