Hello everyone, This problem came out of no where. I turned on my camera to take some pictures and it reads "memory card error" on the top. And if I go to view my pictures on the camera it says the same on the top and on the bottom it says "card locked". So I take the card on and discover there is a little slider on the side of the card with the word lock to it (didn't know this before) so I fix that, dont know how it got switched, put it back in, same message! It's not my camera. I have a PowerShot A710. The card that is giving me problems is a 2 gig sandisk card, but I also have a 16 mg SD card that came with the camera. Tried that, and it works. Like I said, it's not the camera. Also, I was just using my camera the day before, no problems, and the night before I took some pictures off of it, no problem. I really dont know how it could've just went BOOM and died? See I am studying abroad in Paris right now and have quite a few pictures on this card that I would hate to lose! When I put the card into my computer it comes up, I click it, and the bar that shows how much memory is left is completely red, and it says there is 0 space for memory (which isn't true) I think I could probably format the card and it would work? But, those pictures would be lost. Any ideas guys? Thanks!
