Memory card error, memory card locked. canon a470. Camera was working fine had taken photo's all night then switched it back on and this error message appeared, also can't transfer pics to laptop.

There are several possible causes for "memory card locked", "memory card error", or "no memory card". The most common cause is having the tiny slide switch on the side of the card in the wrong position. The second most common is trying to use a 4GB or higher SDHC card with an older camera made before SDHC format came out. There are also other common causes if the above didn't help, with troubleshooting steps for this problem listed here.

SD cards have a slide switch along one edge. The position farthest from the contacts locks the card, protecting it from writes. The position nearest the contacts unlocks the card. If the switch is already in the proper position, slide it fully the other way and then back again.

If that doesn't work, try another card.

Your camera maybe defective in the memory circuit. You can try your card in other A70 cameras? You can format in other cameras as well.

There are several possible causes for "memory card locked", "memory card error", or "no memory card". Some include trying to use of a 4GB SDHC card with an older camera made before SDHC format came out. Others include problems with the tiny slide switch on the side of the card, or the electrical contact switch internal to the camera. The problem may also arise from simple formatting problems if the card has never been formatted in the camera (note that this will also erase the card).

Look at your memory card. SD cards have a slide switch along one edge. The position farthest from the metal contacts locks the card, protecting it from writes. The position nearest the contacts unlocks the card.

OK OK i understand . go setting in camera & save change the photo storage device in your memory card. i am 100 % sure right now all photos are save in your camera internal memory. just transfer it in memory card .

Hi,

I think the problem you are having is not with the camera but with the memory card.

1. Remove your memory card.
2. On one of the sides of the card there will be a lock switch.
3. Change the position of the switch by pulling it up or down.
4. This will remove the lock.
5. Put the card back into your camera.

You will now be able to take photos if the problem was with the memory card.

Kind regards!!

try formatting the card once on a pc and then plug it in your camera....if that does not help either, you'll have to try a different card.

take the card out of the camera and look at it closely. You'll see the LOCK switch.
