The SD Association has an official SD card format utility [Win/OS X/Linux]

SD Memory Card Formatter for Linux ver.1.0.3 for SD/SDHC/SDXC/SDUC The SD Memory Card Formatter formats SD Memory Card, SDHC Memory Card, SDXC Memory Card and SDUC Memory Card (respectively SD/SDHC/SDXC/SDUC 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/SDUC 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/SDUC Cards, but it may not be optimized for SD/SDHC/SDXC/SDUC 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. Note: SDUC Card has no Protected Area. The SD Memory Card Formatter doesn’t support SD/SDHC/SDXC/SDUC Card encrypted by the “BitLocker To Go” functionality of Windows. Please format the SD/SDHC/SDXC/SDUC Card after it has been unlocked.
