Memory media format
New media cards are formatted according to specific standards. If you wish
to reformat a media card, be sure to do so with a device that uses media
cards.
Formatting microSD/SDHC/SDXC memory cards
microSD/SDHC/SDXC memory cards are sold already formatted in
conformity to specific standards. If you reformat an microSD/SDHC/SDXC
memory card, be sure to reformat it with a device such as digital camera or
digital audio player that uses microSD/SDHC/SDXC memory cards, not
with the format command provided within Windows.
Should you need to format all areas of the memory card, including the
protected area, you will need to obtain an appropriate application that
applies the copy protection system.
Media care
Observe the following precautions when handling the card.
Do not twist or bend cards.
Do not expose cards to liquids or store in humid areas or lay media
close to containers of liquid.
Do not touch the metal part of a card or expose it to liquids or let it get
dirty.
After using card, return it to its case.
The card is designed so that it can be inserted only one way. Do not
try to force the card into the slot.
Do not leave a card partially inserted in the slot. Press the card until
you hear it click into place.
Set the write-protect switch to the lock position, if you do not want to
record data.
Memory cards have a limited lifespan, so it is important to backup
important data.
Do not write to a card if the battery power is low. Low power could
affect writing accuracy.
Do not remove a card while read/write is in progress.
For more details on using memory cards, see manuals accompanying the
