What's the purpose of a low level format?

From Canon:

  • IMPORTANT
    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.
