Hello all. I was given a 6th gen iPod nano recently and wanted to transfer some music to it. So I plugged it in, Rhythmbox opened and asked me to format it and I dragged and dropped some music onto it. Simple enough. rhythmbox showed there being music on the ipod. then when I went to walk to work there was no music on it. I plugged it in when I got home and Rhythmbox asks to initialize it again but gives an error message "unsupported checksum type." gtkpod gives the same error message.

So it looks like I need to reformat it and find a program that will actually sync to it. any ideas?
