I tried to use these on 12.3 and probably messed them up by formatting on windows and even under linux if I remember correctly. None of them will mount. dmsg results differ. I’ve had these 2

One of them was reported as write protected by the notification pop up but they don’t have that facility.
At least one of the 3 do show up in YAST’s partitioner. Is there anyway I can forcefully reformat them to something that will mount for a normal user. Ideally it would be best if they could also be read on both Mac and Windows machines. Others in the house use those and that could be handy very occasionally.
