Formatting the CF card on the EOS 5D


Formatting the card
Format the CF card before using it in the camera.
 Formatting a CF card will erase everything in the card. Even protected images will be erased, so make sure there is nothing you need to keep. If necessary, transfer the images to a personal computer before formatting the card.

1. Select [Format].

  • Turn the <> dial to select [ Format], then press <>.
  • The confirmation dialog will appear.

2. Format the CF card.

  • Turn the <> dial to select [OK], then press <>.
  • The CF card will be formatted (initialized).
  • When the formatting is completed, the menu will reappear.
  • A non-Canon CF card or a CF card formatted with another camera or personal computer might not work with the camera. If this happens, format the card with the camera first. Then it might work with the camera.
  • The CF card's capacity displayed on the formatting screen may be lower than the capacity indicated on the card.
  Handling "Err CF"
If "Err CF" (CF error) is displayed on the LCD panel, it indicates that a problem with the CF card is preventing the image data from being recorded or read. Use another CF card instead.
Or, if you have a commercially-available CF card reader that can read the CF card, use it to transfer all the images in the card to a personal computer. After transferring all the images to a personal computer, format the CF card. It may then return to normal.
