I have an A-Data 16gb card and when I put it in my D2 and then plug my D2 into my computer, only the D2 autoruns (popping up with options). When I put my 2gb MicroCenter card in the D2, both the D2 and SD card autorun. My 16gb works perfectly fine and shows up on My Computer otherwise. This isn't a really big deal, but I was wondering if there was something I can do to make it show up automatically for the sake of convenience. I'm using Windows XP by the way. Also my A-data card has been formatted with the Panasonic formatting program.
