So im running windows 7 home and i just moved from my macbook to a new pc build and im trying to transfer my music and apps to itunes on the pc. The only problem is, my 320gb WD My Passport external hard drive does not show up in "my computer" therefore i can not import the music inside it. however, it does show up in disk management, but i cannot do anything to it but look at its properties. How could i get my external hard drive to show in in "my computer" so i could use it?
