<!-- from fixya rte -->Canon powershot card locked? - PowerShot Canon Cameras

SOURCE: canon powershot A540

I had the same problem with a card in my power shot A540. on the side of the card there is a little white slide-bar. Push that bar the opposite direction of where it is and see if that works. Good luck!

SOURCE: I have message 'card locked'

There's a little white tab on the card that slides into "locked" or "unlocked" so you can save your pics. Pull the card and take a good look to be sure the tab is in the correct "unlocked" position.

Remove the SD card from the camera. Look for the tiny slide switch on the side of the card. Slide this switch back to the unlocked position (opposite of whatever its at now).

Have you tried looking at the memory card? Sometimes there is a switch on the card itself that slides up and down to lock, or unlock the card for usage. Hope this helps! (It should be white, and a semi-translucent plastic.)

there is a little switch on the left side of SD cards; if it's down, your card is locked and you cannot copy anything on it or delete anyfile, also you cannot take any picture by it. so you have to change the switch postion. just this! I hope this helps...
