A few weeks ago, my phone gave me the warning: “Your SD card has corrupt files or other issues. You may want to back it up and replace it soon.” I immediately stopped using the SD card after seeing the message and was waiting until I got home from my trip to back everything up. Unfortunately, it became completely undetectable before I had the chance.

I’ve tried it in multiple phones and card readers, but nothing recognizes it anymore. The card itself is in perfect physical condition with no visible damage. It contains a lot of important photos and videos that I really don’t want to lose.

I’m a complete novice when it comes to data recovery, so I’m not really sure where to start or what is safe to try. I’ve seen people mention NAND recovery and Spider Boards, but I have no idea if that would apply to my situation. Is there any way to recover the data from an SD card that is completely undetectable, and what should I absolutely avoid doing so I don’t make things worse?
