Formatting the card on the EOS 6D


Formatting the card
If the card is new or was previously formatted by another camera or computer, format the card with the camera.
 When the card is formatted, all images and data in the card will be erased. Even protected images will be erased, make sure there is nothing you need to keep. If necessary, transfer the images to a personal computer, etc., before formatting the card.

1. Select [Format card].

  • Under the [1] tab, select [Format card], then press <>.

2. Format the card.

  • Select [OK], then press <>.
  • The card will be formatted.
  • When the formatting is completed, the menu will reappear.
  • For low-level formatting, press the <> button to append [Low level format] with a checkmark <✓>, then select [OK].

  Execute [Format card] in the following cases:

  • The card is new.
  • The card was formatted by a different camera or a computer.
  • The card is full with images or data.
  • A card-related error is displayed.

About Low-level Formatting

  • Perform low-level formatting if the card's recording or reading speed seems slow or if you want to totally erase all data in the card.
  • Since low-level formatting will format all recordable sectors in the card, the formatting will take slightly longer than normal formatting.
  • You can stop the low-level formatting by selecting [Cancel]. Even in this case, normal formatting will have been completed and you can use the card as usual.


  • When the card is formatted or data is erased, only the file management information is changed. The actual data is not completely erased. Be aware of this when selling or discarding the card. When discarding the card, perform low-level formatting or destroy the card physically to prevent personal data from being leaked.
  • Before using a new Eye-Fi card, the software in the card must be installed in your computer. Then format the card with the camera.

  • The card capacity displayed on the card format screen may be smaller than the capacity indicated on the card.
  • This device incorporates exFAT technology licensed from Microsoft.
