I am trying to move my Itunes to my new Macbook Pro computer and then sell my old Macbook to my neighbor. Finally, last night, I found my music files in my old computer, attached my Seagate External Hard drive to my computer. It placed an icon for Segate hard drive on my desktop. But when I try to drag the music file to it, it just bounces back to my desktop. I also tried to copy the folder and paste it in the Segate external drive, but won't let me do that either. How do I get the music file into the external drive? This is driving me crazy?????
