Ok, so I am coming to the Maxx HD from the Thunderbolt which came with the 32GB micro SD card. my question is do I need to pretty much completely wipe the card clean to put it in the Maxx? My Bolt was rooted so all of those files were on there but I also have some pics/music/movies too so I guess I'm wondering if I can keep the media files on it or if I should just wipe everything off and restart from scratch basically. Any insight would be great, thanks
