So i am starting to notice when i am listening to my music through my macbook set up, my external hard drive is causing some slight humming through my headphones, when i do turn on the music, it covers it up quite well. all i'm wondering is can this type of interference damage any of my components(headphones, amp, dac etc.) over time?

No, there is no risk of damage. Its a common problem.
