[OT] M1 Mac Mini USB problems

I had exactly the same problem with one of my backup drives, though it was running on an iMac 
that's older. Tried to fix it with Disk Utility and somewhere during the file analysis it 
borked and said it couldn't continue. Then it wouldn't mount. It was effectively hosed, so I 
took it over to my Chromebook and it mounted there just fine, though some of the files were 
missing. So I reformatted it for the Chromebook.

Then I took it back to my Mac and it mounted and I was able to reformat for Mac. Very strange. 
Lost the backups, but it started a new set. I still had the old backups on my second drive, so 
not all was lost.

My thinking is that it was Disk Utility or the Finder database.

All sorts of errors when trying first aid or trying to mount it via first aid. Sent the disk back and the new one did the same thing. I can init it on the win 10 system and then the Mac Mini sees it again. I thought it was an unpowered USB-A hub issue. I then got the power supply for the hub and same thing. I bought an USB-C hub and again same thing. Plugged the Drive directly into the Mac Mini and same problems. My USB keyboard/mouse will not work reliably using either the USB-A or C hub. It seems that the Mac Mini's USB HW/SW is flakey.
