I have an older My Book Essential Edition USB 2.0 500 GB that was given to me. It has a kazillion songs on it, some I would like to keep. I bought a small My Passport Essential USB 2.0 500 GB to use. I have an HP TouchSmart PC that has existing ITunes library I would also like to put on the new Passport. I don’t want to lose any ITunes songs I have in transferring data. Can someone please talk me through this? I am a novice at both computers and definately trying to do this the correct way without losing info or messing up either or both external drives. Is wat I want to do even possible? Thanks for your help…the easier the better.
