Format sdcard option (updated)
Sometimes when copying lots of files to sdcard causes corrupt in portable device. To avoid this we can increase cluster size when formatting. This will also increase read/write performance on sdcard.
Under linux we can use:
mkfs.vfat -h0 -n MYSDCARD -S 4096 -v /dev/sdc1
UPDATE:
using command above seems dont compatible on Windows, you can use this application:

or use this compatible command:
mkfs.vfat -s 32 -S 512 -n "USB DISK" /dev/sdc1 mkfs.vfat -s 64 -S 512 -n "USB DISK" /dev/sdc1 mkfs.vfat -s 128 -S 512 -n "USB DISK" /dev/sdc1
