You will need insert the Memory Card into your computer. The computer will recognize it as a hard drive and give it a letter. It will not be C. All you have to do is after the computer assigns a drive letter to it is RIGHT CLICK on that drive then CLICK on format. Make sure the option for FAT32 is selected and not NTFS. This all assumes you have a windows based computer and you have the proper adapter slot to insert the memory card.
