You can protect a memory card with a password to prevent
unauthorised access. To set a password, select
Set password. The password can be up to 8 characters long
and is case-sensitive. The password is stored in your device.
You do not need to enter it again while you use the memory
card on the same device. If you use the memory card on
another device, you are asked for the password. Not all
memory cards support password protection.
To remove the memory card password, select
Remove password. When you remove the password, the
data on the memory card is not protected against
unauthorised use.
To open a locked memory card, select
memory card. Enter the password.
If you cannot recall the password to unlock a locked memory
card, you may reformat the card, in which case the card is
unlocked and password removed. Formatting a memory card
destroys all data stored on the card.
