Jim: In short, you never get the full advertized amount. There is always a shortage like this, though the actual amounts differ slightly between cards.

When I go to the transfer software, it indicates that my card only has 488 mb available and not 512. How can I get the whole 512 to be available? Thanks, Jim Nuttall--MIchigan
