Canon EOS Rebel T6 can't access SD card. Patriot LX 64GB SDEC SDXD compatible

Have tried several times removing and reinserting 64GB card. Won't read the card. It is full size and not in an adapter. New card not one that has been used so nothing on it.

Full owerwrite in SD Formatter or try a low level format in the camera if it is possible.

Thanks, Did the low level format still didn't work. How do I do a full overwrite in SD formatter?  I'm going back to Fry's tomorrow.

Use a card reader and get SD Formatter (google). Insert the card in the card reader and let SD Formatter overwrite the card.

Thank you!

I have a T5, which has had issues working with 64GB cards, until I performed a low level format in my computer.  I then format the card in the camera, but not a low level format. 

Also, I have never heard of the Patriot brand before.  I suggest that you stick to Lexar or Sandisk memory cards.
