Help. I am not the sharpest tool in the shed, so bear with me. I am trying to set up a home network and am really struggling. My goal is to be able to use an external hard drive to access pictures, movies and music via iTunes. I have a brand new Macbook Air - literally 2 weeks old. I have a Verizon Wireless cable modem and have hooked up an Airport Express to this via ethernet. I then hooked up a Seagate 4TB hard drive to the Airport Express via USB cable. I have downloaded the driver for the hard drive to my laptop and have run Airport Utility. I can locate the Airport Express, however I cannot 'see' the hard drive. I have followed the posted instructions several times, but I still can't make this work. Any help making this work would be appreciated. Thanks in advance!
