All of a sudden my phone is telling me that my SD card is damaged and asking me to reformat it which I don't want to do because I don't want to lose what I have on it. Has anyone else experienced this and know how to fix it?
Try opening it on a PC with perhaps an SD card reader. If it won't open there, it might need to be reformatted. If it will open, save the contents to PC and then reformat the card from within the phone storage options.
