When I got a new Compact Flash Card (Sandisk Extreme pro UDMA6) I formatted it using my Laptop (Win 10). I did both a quick format and a longer format. My camera keeps saying the card isn't formatted. When I try to format using the camera itself it says this card can't be formatted. I'm ready to start losing what little hair I have left over this. This is the final hurdle I have to clear before I can finally start taking pics with this camera. Please help me if you can. Don't know what to do next. Thanks very much.
