GeaOk, menu disks is using format to detect disks.
You can now
- mirror manually with the disk-ids
What happens if you enable partition support in napp-it
where parted is used instead of format.
>> Menu disks >> Partitions >> enable Partition support
You picked it. That works, both USB's are displayed and have a status of removed.
That said enabling partition support does not appear to be 'sticky', clicking enable partition support results in the USB's being displayed, but then clicking on 'partitions' results in just the main disks being displayed.
