There is a capital C usually on the card and a number inside.

Definitely strange that all the cards have the same issue. My first thought was the card reader itself but I guess you've eliminated that. Next thought would be the cards were locked because then they won't write but you seem sure they weren't locked. Lastly, seeing as you format the cards each time I figured you may have accidentally done it in NTFS, in which case the cards won't work in the trail cams. Cheap cards are easier to corrupt but it seems you have quality ones there.
Back to formatting, I have no idea why you would feel the need to format the cards each time. I have had trail cams for ages and have never had an sd card fail. When I get a new memory card I format it in fat32 on my pc and then unless I have an issue I never do it again. I also don't delete the directory that the trailcam creates unless I'm switching brands, when in that folder and the card is getting fuller I just select all in the edit function and then shift+delete to permanently delete them and bypass the recycle bin. My reasoning is that flash memory is limited to how many read/write operations it can do, once it hits that max it won't work anymore, so I try to limit that as best as I can. So far it has worked well for me.
Finally, as it seems that the cards, or at least one for sure are functioning now I would lean to a formatting issue. Have you tested all three?

Cheers

Many thanks to all who have kindly offered advice. I'm not sure what the issue was, it's never happened prior to this. All seems to be working oridinarily now, so I must have done something wrong? I wouldn't admit that to my wife though, since she refers to me as a "work in progress"

Anyway, thanks all!
