NTFS was designed for mechanical hard drives, USB drives are solid state. NTFS uses journeling to help prevent errors on mechanical hard drives, journeling adds overhead to solid state USB drives.
Near as I can find this works on Windows to format a drive to FAT32.
cmd (Win+R and type cmd) diskpart list disk select disk 1 (1 must be a number of your flash card) clean (this command erase all data on selected disk!!!!) create partition primary select partition 1 format fs=fat32 quick
