How to Unlock SD Card?

A Secure Digital (SD) card is a storage device that allows you to transfer information between devices like cameras, phones, Wii consoles and computers. They are usually only 1 inch wide by about 1 1/2 inches tall. They can be locked by sliding a switch on the side of the disks so that stored data cannot be removed or added. The reading device responds to the card as either locked or unlocked. Here is how to unlock an SD card.
Have a look on the side of the card, it has a tiny white strip, it moves up and down, just move it and it will unlock.

Many times people do not realize that a SD card can be write protected or locked. They will try to download pictures or make changes to the pictures and the SD card will not allow them to do it. The little lock feature on the side of the card will write protect the SD card so that changes cannot be made. You will need to unlock the SD card to be able to make the changes that you want to make or download anything from it.

To allow the SD card to be accessed is a simple as sliding a small tab on the side of the card to the unlocked position. 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 camera or PC to be able to do this.

Here is a picture of an SD Card 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.

This feature can be very useful to make sure that you do not inadvertently erase data or pictures 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 do not erase your pictures.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.
