This on a 2017 iMac Running Catalina.
I have an older WD Elements dive on which there is a volume called Media. On this volume I keep videos, photographs and lots of other stuff, including iMazing backup files.
I decided to buy a Samsung T7 SSD on which to store this stuff. I partitioned the drive into two volumes, one of which is formatted as Mac OS Extended, as is the volume on the old WD drive.
I used CCC to copy the old Media volume onto the new drive. Both volumes have the same owner/group (root/staff) and permissions (755). Neither volume has "Ignore ownership" enabled.
iMazing refused to work with the new volume insisting that it didn't have read/write permission on the drive. I eventually gave up trying to fix this and simply changed the permissions to 777 after which iMazing was happy.
A couple of questions:

A couple of questions:
- Why would iMazing be able to r/w from one drive and not the other?
- What should the ownership and permissions be on an external drive? I want all users to be able to read and write from the drive. root/staff 755 seems odd to me, but has worked fine with the volume on the older drive.
