How I can get my memory sd card work again?
I had my SD memory card for a few months and have been using with my camera Nikon, but now when I turn the camera on it says, "Warning, this memory card is unreadable." it was fine a few days ago and now let me see the pictures they have taken or downloaded to my pc. I can not use my camera when the card is in it, but when it works out well. i havnt changed any configuration or anything. Is there any way I can make it work again?
You may need a new memory card. If you have taken the card, turn the camera, put it on and tried again and still get error – most likely the SD card is bad. Sometimes happens with any memory card is possible, are very sensitive. Good luck, I know it's frustrating!
