SD Memory Card Formatter 5.0 for SD/SDHC/SDXC
The SD Memory Card Formatter formats SD Memory Card, SDHC Memory Card and SDXC Memory Card (respectively SD/SDHC/SDXC Cards) complying with the SD File System Specification created by the SD Association (SDA).
It is strongly recommended to use the SD Memory Card Formatter to format SD/SDHC/SDXC Cards rather than using formatting tools provided with individual operating systems. In general, formatting tools provided with operating systems can format various storage media including SD/SDHC/SDXC Cards, but it may not be optimized for SD/SDHC/SDXC Cards and it may result in lower performance.
SD/SDHC/SDXC Cards have a “Protected Area” for SD Card security purposes. The SD Memory Card Formatter does not format the protected area in the SD/SDHC/SDXC Cards. The protected area shall be formatted by an appropriate PC application or SD host devices that provide SD security function.
The SD Memory Card Formatter doesn't support SD/SDHC/SDXC Card encrypted by the “BitLocker To Go" functionality of Windows. Please format the SD/SDHC/SDXC Card after it has been unlocked.
