None of my 4 cards will erase or re format.They all say write protected.Two of them I bought across the counter.How do I remove the write protection so I can delete and add videos?I use a card adapter every time I never hook the camera to the computer,and use an external charger.
i know it sounds daft but try another usb port,ive found that if you use one more than others the computer gets the hump and wont play. do you use an SD card adaptor? if so it might have the little switch on the side that puts the write protect on the card,just switch it the other way and you should be away :-)

Liek Davidwhitefield says, some SD cards have write protection switches on them (these are adapters for microsd)
Double check & see if that is the problem.
Try and format the card when putting the card into the camera that way, it will popup as an external drive in your windows explorer (windows) or disk viewer on mac
