Solved! SD card formatted error, HELP!

[uslucychan]

Hi there, I bought a new SD card and took many pictures on my Nikon. I got home and tried to read in my computer with a warning that SD card not formatted. I can't read the pictures and put the SD card back into my Nikon, and gives me an error message. I took alot of important pictures yesterday, what is the best way to recover. HELP!

Try other computers first. If it doesn't work, it is very likely that the SD card is damaged.

I don't know what causes the SD cards to fail all of the sudden but the two I've had fail wound up having a hairline split in them and folded in half when I played with them. I don't know if it's from heat and then taking them out and putting stress on them but both failures were physical damage
