The fix for this problem is simple. Do you know what SD stands for? Secure Digital. The little yellow or gray slider on the side of you memory card enables or disables the write protection, thus, you get your error. When you put the card in, it slides it down and stops the card from writing. To fix this, take a little peice of tape and cover the slider while in the up (unlocked) position. This will prevent it from sliding to the locked position. Be careful not to cover any of the copper pins on the SD card with tape!
