| This happened to me once, not sure if you have the same type of card, SD?
Most of them have a tiny switch on the card that can be locked or unlocked. I had inadvertantly moved the tiny switch to lock.
The only other advise if your card does not have the lock switch, try putting the card in a card reader and use your computer to format it, or, format in the camera if that option is available.
Good Luck! |
