Konica Minolta DiMAGE G600 User Manual (en)

The response time during recording and playback is longer with MultiMediaCards compared with
SD Memory Cards. This is not a defect, but rather due to the specifications of the cards. When
using large capacity cards, some operations like deletion may take longer. 
The SD Memory Cards and Memory Sticks have a write-protect
switch to prevent image data from being deleted. However, when
the card is protected, images cannot be recorded. If an attempt
is made to record or delete an image with the camera, the card-
protected message appears and both viewfinder indicator lamps
blink. For memory card care and store see page 100.
If the unable-to-read message appears, the inserted card in the
camera may need to be formatted. A card used in another cam-
era may also have to be formatted before being used. A card can
be formatted in the setup menu (p. 71). When a card is formatted,
all the data on the card is permanently erased.
