.Using a Memory Card

• SD memory cards and SDHC memory cards have a write protect switch. Use the switch when you need to guard against accidentally deleting data. Note, however, if you write protect an SD memory card you must then turn write protection off whenever you want to record to it, format it, or delete any of its images.

If a memory card starts to behave abnormally during image playback, you can restore normal operation by

reformatting it (page 170). However, it is recommended that you always take along multiple memory cards whenever using the camera far away from the home or office.

As you record data to and delete data from a memory card a number of times, it loses its ability to retain data. Because of this, periodic re-formatting of a memory card is recommended.

Electrostatic charge, electrical noise, and other phenomena can cause data to become corrupted or even lost. Make sure that you always back up important data on other media (CD-R, CD-RW, hard disk, etc.)

.Discarding or Transferring Ownership of a Memory Card or the Camera

The format and delete functions of the camera do not actually delete files from the memory card. The original data remains on the card. Note that responsibility for the data on a memory card lies with you. The following procedures are recommended whenever you discard a memory card or the camera, or if you transfer ownership to another party.

When discarding a memory card, either physically destroy the memory card or use commercially available data delete software to completely delete the data on the memory card.

When transferring ownership of a memory card to another party, use commercially available data deletion software to completely delete the data on it.

Use the format function (page 170) to completely delete the data in built-in memory before discarding or transferring ownership of the camera.
