How Do I Format a Memory Card? (EOS 5DS / EOS 5DS R)

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 all data on the card.
  • Since low-level formatting will erase all recordable sectors on the SD 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 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, execute low-level formatting or destroy the card physically to prevent the 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.
