Canon PowerShot G9 User Manual page 235

Please note that formatting (initializing) an memory card erases
all data, including protected images.
You are recommended to use memory cards that have been
formatted in your camera.
• The card supplied with the camera may be used without further
formatting.
• When the camera is malfunctioning, a corrupted memory card might
be the cause. Reformatting the memory card may solve the problem.
• When a non-Canon brand memory card is malfunctioning,
reformatting it may solve the problem.
• Memory cards formatted in other cameras, computers, or peripheral
devices may not operate correctly in this camera. When that
happens, reformat the memory card with this camera.
If formatting in the camera does not work properly, turn the
camera off and re-insert the memory card. Then turn the
camera back on and format again.
Be careful when transferring or disposing of a memory card.
Formatting or erasing the data on a memory card merely
changes the file management information on the card and does
not ensure that its contents are completely deleted. When
disposing of a memory card, take precautions, such as
physically destroying the card, to prevent personal information
leaks.
