Solution: Change the memory card lock switch to the normal setting

The SD card has a lock switch to prevent existing data from being erased. To record images or movies this switch must be in the normal (non lock) position. Different brands of SD memory cards may identify this switch differently. Regardless the procedure should be the same. Please remove the card from the camera and ensure that the switch is not in the locked position.

You should be able to retrieve photos, but not writing or erasing if the switch is switched to write protect.

If it's not functioning correctly, the camera may need service at Canonusa.com.

Usually, the write protection is on the memory card itself.
You should power off the camera, take out the memory card and move the little switch on it's side to disable the write protection.

Good luck,
