OK, so this is getting worst. At first it was just a one time thing. Tonight it happened about 5 out of 10 times I tried to use the camera. Sometimes turning it off and back on would fix it. Sometimes I had to remove the battery. Once I had to remove the card.
Could someone tell me what folders I need to copy to keep what I already have on the card? I have a new 16GB card that I can switch to. Should I format it in the EVO or use the SD Formatter that someone mentioned above?
