Format an SD Card Properly using SDFormatter..

How do you normally format your camera SD card? If you use the built-in format option on your camera, that’s fine, but you shouldn’t use Windows to format an SD card, at least according to the SD Association. Instead, if you want to prolong the life of your SD card, you should use SD Formatter, a free program that properly formats an SD or SDHC card according to official standards.
