UTStarcom PPC-6700 / XV-6700 / HTC Apache

I recently purchased a 2GB mini-SD card for my XV-6700. I am looking to use it for storage on my phone and to transfer information to and from my laptop. When I insert the card into my phone it prompts me to format it. When I load the card into my laptop it also prompts me to format. When I format it on the laptop the phone does not recognize it. My 512MB card works fine on both. Has anyone else had this problem with the 2GB card? Does anyone have a solution as to how I can get both devices to recognize it? Any information would be appreciated. Thanks.
