I have bought an external hard drive on which I'd like to store some of our favourite music as a back up. By using the Spotify NoteBurner app I've transferred several CDs from Spotify to the HDD in FLAC format. I have created a folder for each artist, then sub folders for individual albums. I can connect the HDD to the rear of my streamer via a USB cable but how does the streamer "pick up" the HDD please? It's a brand new Seagate 8TB unit. I hasten to add that this is all new to me so am hoping for a bit of advise please. Thank you
