WD 1TB not recognised on 13" macbook pro retina (late 2013) even though it is exFAT file structure. The same drive is recognised on iMac and an old Dell laptop. I also have a seagate 2TB external hard drive (powered) that is recognised by my macbook pro.

I just bought a late 2013 macbook pro retina 13" a few days ago. I am trying to transfer all my music from my old Dell laptop. I formatted by 1TB Western Digital MyPassport to exFAT to allow read and write on both operating systems. The 1TB WD My Passport is recognised by both my Dell and iMac but not my new macbook pro retina 13 (late 2013). My 1TB WD My Passport is USB 3.0 with USB 2.0 backward compatability. I also just bought a 2TB Seagate Desktop Backup Plus (which is powered) for backing up and extra file storage, THIS WORKS! I don't understand how this works on my macbook pro but my 1TB western digital my passport doesn't. PLEASE HELP!! I have done full formats as well (not quick ones) which take nearly 8 hours. PLEASE HELP
