you need to do some more work in Disk Utilty.


First make sure the tint View menu indicates "Show all devices:


next select that drive by its immutable, factory-assigned DEVICE-name,

choose ERASE, specify exFAT, and give it a unique name.

next, select the drive and do a Repair disk/Fisrt Aid on the device AND separately on the exFAT Volume.
