Card Locked.. I went to playback and scrolled down to protect. I tried changing it to off but it isn't allowing me to change the setting. Is there something else I need to do to be able to access that?

<p>Many times people do not realize that a <span style="font-weight: bold;">SD card</span> can be <span style="font-weight: bold;">write protected </span>or locked. They will <span style="font-weight: bold;">try to download pictures</span> or <span style="font-weight: bold;">make changes to the pictures </span>and the <span style="font-weight: bold;">SD card will not allow</span> them to do it. The little lock feature on the side of the card will <span style="font-weight: bold;">write protect the SD card</span> so that changes cannot be made. You will need to <span style="font-weight: bold;">unlock the SD card</span> to be able to make the changes that you want to make or download anything from it.<br /> <p><br /> <br /> <p><span style="font-weight: bold;">To allow the SD card to be accessed</span> is a simple as sliding a small tab on the side of the card to the <span style="font-weight: bold;">unlocked position</span>. Usually this means sliding the tab towards the back of the card and away from the front of the card. The card will have to be removed from the <span style="font-weight: bold;">camera</span> or <span style="font-weight: bold;">PC</span> to be able to do this.<br /> <p><br /> <br /> <p>Here is a <span style="font-weight: bold;">picture of an SD Card</span> and you can see the tab on the side of the card. It clearly shows you what is the locked and unlocked positions on the card.<br /> <p><br /> <br /> <p><img src="heatman101_2.jpg" /><br /> <br /> <p><br /> <br /> <p>This feature can be very useful to make sure that you do not inadvertently <span style="font-weight: bold;">erase data or pictures</span> from the card. If you have children viewing pictures on the SD Card make sure to lock it before allowing them to play around to make sure that they <span style="font-weight: bold;">do not erase your pictures</span>.<br /> <p><br /> <br /> <p>As you can see this is a very good feature to have and it will be very useful to you, but you do need to remember to unlock it before trying to make changes to the card.<br />
