Solving media card reader problems
Media card will not work in a digital camera after formatting it in Windows.
Cause Solution
By default, Windows will format any media card with a capacity
greater than 32MB with the FAT32 format. Some digital cameras
use the FAT (FAT16 & FAT12) format and can not operate with a
FAT32 formatted card.
Either format the media card in the digital camera or select FAT
le system to format the media card in a computer with Windows.
A write-protected or locked error occurs when attempting to write to the media card.
Cause Solution
Media card is locked. Locking the media card is a safety feature
that prevents writing to and deleting from an SD/Memory
Stick/PRO card.
If using an SD card, make sure that the lock tab located on the
right of the SD card is not in the locked position. If using a Memory
Stick/PRO card, make sure that the lock tab located on the bottom
of the Memory Stick/PRO card is not in the locked position.
