This unit did not come with an SD card. I installed one that was loaded with data from my Razr Maxx. That worked fine but I wanted more storage so I purchased a 64 Gig Mirco SD. I copied the data from the first card with my PC, and then loaded a bunch of Music and some movies... However, when I inserted the new card and tried to mount it the device shows a very quick message that the SD card is broken or unusable, something to that affect.
I put the card back into my PC and it reads everything fine. This may be the way the newer versions of Android write/format SD cards, that's my guess anyway.
What do I need to do to make this SD card work and can I preload it from my PC?
