What kind of memory card is your trying to format and where are you formatting it from, camera or computer?
SD card have a switch on the side for write protection.
Hi Rexter, Just found your comments when googling for answers to why my SD card said "Card Protected" when I inserted it into my camera after viewing photos on the computer. I didn't even know there was a little switch on the side of the card It's people like you who help people like me, computer and technology illiterate, to find the answers to the problems. Thanks heaps, I love my friend Google
