External Hard Drive Making Chirping Noise

I've owned this Mac Pro for over two years now, and in that time have been consistently pleased with its performance. I use it predominantly for compiling and editing photographs via Lightroom and Photoshop, as well as holding my iTunes library. For those purposes the computer is very quick and efficient. Its six thunderbolt 2 connections are exceptionally fast; I use all six to connect both the monitors and external hard drive arrays (see photo). I do wish it offered more than four USB 3.0 connectors, but that is a situation easily rectified with an external USB hub. In two years of continuous use I have yet to experience a problem with the machine. The computer is quite diminutive, making it easy to place in my office. And, it's sleek Darth Vader Trash Can look is appealing and attractive. Unfortunately, the one drawback of its size is that internal upgrades are impossible. You are extremely limited in the amount of storage you can have inside the computer (4TB). Therefore, external hard drive arrays are the only solution to those who need significantly more storage capacity, making the area needed for the computer and peripherals significantly larger. That minor issue aside, this is the best all around desktop computer I've owned, which is saying something. For photographers, you won't find a faster, more reliable product.
