Hello Peter, Most of the cards you will find will be Type I. All of the Type II cards I have seen have been labeled as Microdrives. It was a little confusing at first for me, because I found a card called the Sandisk Ultra II card. As it happens, this is actually a Type I card. <grin> Where are you looking online? Maybe we can offer some help. But if it is not labeled as a microdrive and is simply called CompactFlash, odds are it's the kind you want.
