I just got my Amaze today. This is my first time using Android, but I managed to get to the sd card settings. The total space & available space says unavailable in gray. I tried using an sd card adapter to plug it into my computer, but my computer didn't recognize the card either. I used this microsd card on my Dell Venue Pro a few months ago, but erased everything off of it. So the card works. It's a 32GB class 4 Sandisk.... any help ?
