I own a HPX170 and I am trying to reformat the P2 card using the supplied software. Normally, when I load my footage via the FW port the P2 cards mount of the desktop as "No Name". I would like to use the software to name the cards with the software but when I open the P2 card application I cannot find the cad information. Can you format using the FW port or do I need to purchase a P2 card reader in order to format the cards in a way that is less confusing?
