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.

Canon's version of a low level format takes a few seconds. There is no way it is overwriting data. I would not trust it to make all data inaccessible.  If I had sensitive data on a card that needed to be cleared I would use a program to write the entire disk with 1 and 0s.
