I typically use Canon 70D, 6D, or EOS R. I have never had an issue swapping the card between the cameras or reformatting. Recently I used a Sandisk Extreme PRO 128gb memory card in a different video camera and formatted it before recording.
After taking all my files off the card and putting it back in the Canon camera I received a message saying the card cannot be formatted.
How can I reformat this card so that my Canon camera accepts it again?
