This is what I am trying to figure out. UD has been doing it this way without specifying the partition for a long time.

Ok. I stand corrected. The log message shows the drive and not the partition. It is actually formatting /dev/sdg1. This tells me what is wrong with the nvme format command now. It needs the partition as nvne0n1p1.
Fix is now coming.
