By playing around with some of the things on the SD Card, I found that when I delete the music off of my phone through USB via a MacBook Pro, they are removed from the music players but are still counted as space used on my SD Card. For example I had 300 mb left while still having 5 gb of music on my phone and after I moved the items to trash and disconnected the phone from the laptop, it still showed 300 mb of open space. Any suggestions on this?
