I just purchased a new 4 GB SDHC Card. My Gateway / Vista 6.0 15 in 1 card reader says it recognizes SD cards but I see no mention of SDHC. If the card reader doesn't support the HC card can I accomplish all that I need to (formatting, copy, backup) through the associated drive recognized with the card installed in my 720? or should I take the card back and get a regular 4 GB SD Card? I wanted to load my maps, POI's. etc. on the card.
