samsung galaxy yp-g50 mp4 player not recognised by laptop or pc

Ive bought my brothers mp4 player off him today, samsung galaxy yp-g50. I know it works as he used it today before giving it me, and ive added my spare micro sd card and the music plays fine. However when I use the usb cable to link it to my laptop to drag and drop the files like my brother showed me, it doesnt show up in my computer at all. Ive mounted it as usb device as directed by my brother but its just not picking it up at all.

Also tried in on my pc and got the same result. I just cant figure it out, it worked on the pc at my parents, my brother added an album to show me how before i took it. Have also downloaded a newer windows media player to see if I can sync it via that, again nothing. Im sure its got to be something im doing but im getting frustrated and cant see it lol.

Does anyone have any ideas????
