Altough Motorola says the Droid Razr Maxx only supports a 32gb card, I've read many reports of people using this 64gb card, so I took a chance with it.I formatted it in my phone and started loading music and movies onto the card by connecting my phone to the computer with the USB cable.Note:  I had read to NOT format the card in the computer because it will only show up as  27gb of memory available - I was careful to heed this advice, though did play with it in the computer itself (without formatting it, just looking) and it does only show up as 27gb . However, in my Droid it definitely shows as 64gb (well 59 and change)So far the card is functioning as it should: I have  played music, looked at pictures, and watched a little bit of a movie, all stored on the card, and eveerything seems to be working iin blissful Droid perfection.
