I just switched my music on my 4gb samsung last night. I deleted everything of it because I was filling it all up with new stuff anyways. When it got to about half way while filling it up again, my computer crashed. Not too bad since I have all the stuff it put on first, but since it kinda fills it in reverse of how you drag stuff onto it, none of the tunes I put on first because I really wanted to have them got put on, Grr...
