I have a Canon 1DX Mark III. When I purchased this Camera, I received the Card and Reader. I have had the Card corrupt numerous times when I plug the card into the reader and the reader into my computer (I have two and it happens with both - Windows 10 Newer computers). It does not recognize any volume and tells me I have to reformat my card. One time my computer asked me if I wanted Windows to repair the card and it worked great - got all my photos! I don’t know how to have Windows do that though. I also downloaded the Recovery Software from Sandisk and that is not helpful at all. Any help if greatly appreciated!! Thanks in advance. Also, I always reformat the card in the camera before I take any photos and do not delete any photos on the card in the camera. Thanks in advance. DeeDee
