Hello, I'm wondering if you can help me. I recently bought a D7200 with two 64GB SDXC Cards. All has been fine up until recently, I have the error "this memory cannot be used, card maybe damaged. Insert another card. This is on both cards with no files at all on them. Please can someone advise what I need to do. I've tried formatting them into exFAT format, but my computer just doesn't like the cards at all. The issue have arose since I put the cards in the computer. I have a Sony Vaio running Windows 10. I have bought two further SDXC cards which work perfectly well.
