I know I usually only post pictures here, but I’ve run into this problem several times with photographers (particularly amateur with the little cameras), although I’m sure other people have had the same problem.  You plug in your SD Memory Card and it says something like “Memory Card Locked” or “Memory Card Unavailable.”  Don’t freak–your card isn’t necessarily unrecoverable!

If you look at the picture of the card above, note the notch on the left side. If you look carefully, you’ll see a part that’s a light grey.  You can see it more clearly in this picture.

What you may not know is that this is a little button–it slides up and down. And it is what locks up a memory card.  Basically it’s a key that protects your information from being hurt, so it locks the information down. You cannot access it, and you cannot change it.  Unfortunately, this is going to bring up error messages when you plug the card in. This is especially an issue for photographers who frequently pull the cards in and out of the camera. A lot of times, you’ll accidentally trigger this little button without realizing 

All You Have To Do Is Re-Click The Button.  

That’s it. Real Simple, no hassle, no computer-wizards necessary.  🙂
