Memory card on camera?

Well, I had bought a digital camera recently. I had put a memory card in it, and then didn't use it for a while. I turned the camera on, and it says that the memory card is locked. Why does this mean? Why does it say this? And what can I do about it?

Take the memory card out. Then take the batteries out. Put them all back again. Hopefully it will work. Otherwise, there is also a little lock on the card. Make sure that it is not in lock position.

The above answer is correct, so give him the 10 points.

I agree

take out the card, search for a up-down slider which reads "lock-unlock" put it the other way round. ur done.

ther is a little slider swith on all media cards. Make sure it is in the unlock position.

as above.

There is no slider/lock on any modern card (ie:xd,cf multi media),wipe the card with a clean lint free cloth and retry.
