About Low-level Formatting
Do low-level formatting if the card’s recording or reading speed seems
slow.
Since low-level formatting will erase 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, 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, destroy the card
physically to prevent personal data from being leaked.
The card’s capacity displayed on the format screen may be lower than the
capacity indicated on the card.
