>>580515okay, everyone calm down.
transferring files via usb on android to, what i am guessing is, a microsd card.. is slow. it's incredibly slow. if you copy a hundred files it'll take a while. if you copy a thousand, it'll take ages.
last time i backed up the 128GB card in my android pad, it took most of a day.
OP: try copying one folder of music at a time, and let it run.. sometimes it seems like it's not doing anything - that's just the microcontrollers in the microSD card trying to work out where to put the next file. these controllers are small, and not very bright.
