There are two types of formatting, general formatting and low-level formatting.
In the following cases, formatting your memory card with your camera is recommended.
When using a newly purchased memory card.
When using a memory card that has been formatted with another camera or a computer.
If you encounter one of the following problems, performing a low-level format may solve it.
The [Memory card error] message appears.
The speed at which images are written to or read from the memory card has been reduced.

The camera does not work properly.
Caution
Formatting (initializing) a memory card erases all data on the memory card. Copy the data from the memory card to a computer or other devices before formatting.
Formatting or erasing data on a memory card merely changes the file management information on the card and does not ensure its contents are completely deleted. Be careful when transferring or disposing of a memory card. When disposing of a memory card, take precautions such as physically destroying the card to prevent personal information leaks.
With Eye-Fi cards, please install the software included on the card to your computer before initializing the card.
