I have an ibook with 40 Gb hard drive that is now full. I bought a LaCie De 250 Gb external hard drive. I have installed it and I want to load my itunes into it. I saw another thread that said that I should "drag the itunes file to the new hard drive". My icon says "ED Mini". I opened the itunes program and reduced it, dragged it the ED Mini icon but it would not drop in. What do I do? Thanks.
