The maximum memory storage capacity for that camera is 2GB.
Cards with more capacity (4 GB and higher) are called SDHC.
Which means SD memory card High Capacity.
The SD600 was designed before SDHC cards became available.
It does not contain the necessary circuitry and firmware for High Capacity cards.
What is the max Scandisk card I can use in this camera? Si far I use 2GB
