I recently got a Droid 2 and I love it. The salesperson at the Verizon store put my old 2 gig SD card with my pictures, videos, etc. into my Droid so I could still have access to my pictures before I transitioned to the 8 gig card that came with my phone. I moved all picture, video, and sound files from the old card to my Mac with the intention of moving those files to my new card, but when I plug my Droid in, the phone doesn't acknowledge that the new SD card is in it. It does appear on my computer, though. This changes, however, once I unplug my Droid because the phone recognizes the card, but none of my files are on. How do I get my phone to recognize the SD card while it's plugged into the computer and move all my files?
