What are you using to format it just Windows? You might try a third party format tool and see if that works. I’ve searched but can’t find the post but when this came up a while ago the problem was the drive in the third party enclosure. I think they had to connect as an internal and format it then put it in the enclosure. If I can find the post I’ll add the link. It may have been in the external drive section. I think it was in the last 2 weeks.
