You should really give ua more details. Card's brand? Have you been ableb to use it with other phones? There can be a lot of reasons. But if sd card is working properly then you should be able to see it in settings > storage. If you are able to see it there, just format it there (unmount before formatting). Maybe it will help. But as I have said, we need more details. Good luck!
