Formatting the cards on the EOS 5DS and EOS 5DS R


Formatting the card
If the card is new or was previously formatted by another camera or computer, format the card with the camera.

 Cautions for Formatting the Card 

When the card is formatted, all images and data in the card will be erased. As 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. Select the card.

  • [] is the CF card, and [] is the SD card.
  • Select the card, then press <>.

3. Select [OK].

  • The card will be formatted.

  • When [] is selected, low-level formatting is possible.
    For low-level formatting, press the <> button to append [Low level format] with a checkmark <✓>, then select [OK].

 Format the 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.

Low-level Formatting

  • Perform low-level formatting if the SD card's reading or writing speed seems slow or if you want to totally erase the data on the card.
  • Since low-level formatting will erase all recordable sectors on the SD card, the formatting will take longer than normal formatting.
  • You can stop the low-level formatting by selecting [Cancel]. Even in this case, normal formatting will be completed and you can use the SD 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 on the card must be installed on 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.
