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 160). 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 160) to completely delete the data in built-in memory
before discarding or transferring ownership of the camera.
