I have my mac laptop in an adjacent room to someone's bedroom, & I use head phones to listen to music so as not to wake them while working with content on my external hard drive.

I notice I have this when my external hard drive is plugged into my hub & turned on, what is it? is it serious?

I dont get this sound when my hard drive is not turned on & running.
