Before Using your SDXC Memory Card

The first SDXC memory cards and SDXC host products (digital cameras, video cameras, mobile phones, etc.) have begun to reach the consumer market. As an early adopter of the new SDXC technology, it is important that you understand how to use your new SDXC memory card to its greatest capacity.

Confirm Compatibility

Before inserting your SDXC memory card, confirm the host product is SDXC compatible by locating an SDXC logo on the host product or referring to the host product's instruction manual or manufacturer's information.

Understanding Backwards Compatibility

• SDXC memory cards can be used only with SDXC host products.
• SDXC host products can use SD, SDHC and SDXC memory cards.
• SDHC memory cards can be used with SDHC and SDXC host products.
• SDHC host products can use both SD and SDHC memory cards.

Only Use SDXC Memory Cards in SDXC Host Products

SDXC host products are backwards compatible with earlier SD and SDHC memory cards. SDXC memory cards should not be used in non-compatible host products. If you need to format an SDXC card, you can format by using SDXC host products or the SD Formatter 3.0.

If an SDXC memory card is inserted into a PC or a host product that does not support SDXC memory cards, a message may prompt you to format the card. Do not format the SDXC memory card in a non-compatible host product; it will erase the data on the SDXC memory card and format the card for a different file system that will no longer work with SDXC host products.
