Go ahead and try-out the full capabilities of your SD, SDHC and SDXC memory cards with SD Formatter. The application is designed to run on both Windows- and Mac-based computers.
This easy-to-use software application was specifically released for the following types of memory cards: SD, SDHC and SDXC.
The memory cards that use SD/SDHC/SDXC standards have a so called "Protected Area" used for the SD standard's security function. In order to format all sorts of devices, the operating system integrates its own utilities. Using standard formatting utilities provided by Windows may result in less than optimal performance from your SD memory cards.
Formatting your SD, SDHC and SDXC cards with programs such as SD Formatter will result in better or optimal performance for your memory cards. SD Formatter 3.1 provides SD security function to format the "Protected Area" in the memory card.
Some SDXC memory cards may not be recognized correctly by the computer, thus you may need to install a SDXC driver. Formatting a SDXC memory card that is not properly recognized by the operating system will result in data loss. You will have to format the card using a different file system.
SD Formatter 3.1 is a simple and reliable utility to safely format your SD, SDHC and SDXC memory cards.
