I have a good condition Nikon d3300 that randomly started giving me the error "This Card is Not Formatted". Then when I try to format, it says "the option is not available in current settings or in the cameras current state". I checked and the card is not manually locked. No damage has happened that I am aware of. Please help! I have wedding photos from my daughters wedding on this card!
It sounds like some communication or compatibility problem with the card. I would try accessing your photos by putting the card in an external card reader on a computer. The card readers are not expensive. https://www.amazon.com/s?k=sd+card+reader
If this is a microSD card, in an adapter to fit an SD slot, then this is classic problem.
If that's your situation, then replace the card with a standard SD card (no adapater), and the problem will go away.
You can also try different card adapters, but it's NOT simply a matter of replacing one bad adapter with ANY other one. It's more like the fussy camera/microSD card combination will only work with one very specific adapter. In my case, I had best luck with adapter cards that came with Samsung microSD cards. Other reliable brands, like SanDisk, did not work.
BTW, this problem showed up for me an a entry-level camcorder (Canon Vixia HF-R800), and no other (out of 8 other cameras/camcorders I've used).
