  The following options have been headed to the FORMAT item on the SYSTEM screen.
  Options: 
  QUICK FORMAT : Initializes file system information only.
  ERASE FORMAT : Initializes file system information and initializes by erasing all user data areas on the SD card.

Using the ERASE FORMAT option might restore an SD card that has decreased writing performance, but 
this process takes some time.
We recommend using an AC adapter or similar power source when conducting ERASE FORMAT.
