Formatting an SD/SDHC/SDXC memory card
SD/SDHC/SDXC memory cards are sold already formatted in conformity to
specific standards. If you reformat an SD/SDHC/SDXC memory card, be
sure to reformat it with a device such as digital camera or digital audio
player that uses the SD/SDHC/SDXC memory cards, not with the format
command provided within Windows.
Should you need to format all areas of the memory card, including the
protected area, you will need to obtain an appropriate application that
applies the copy protection system.
