SDXC card not working

I have a 128gb SDXC card that I can’t get to work in the media player. My computer has no problem loading up the card and adding files to it but when I stick the card in my media drive it does not show up. When I open the app on my phone and tablet and go into settings it shows – gb available card memory. Is there something I need to do to get the card to be reconized by the media drive? Thank you

how is it formatted?
