Lets face it, some peoples hearing is better than others. My hearing is not that great anymore so a noisy spinning hard drive is just not a problem for me. However, I know that spinning hard drives (mostly used for backups or storage) make a certain amount of noise. After all, there are mechanical parts moving around in there. If noisy hard drives bug you, then read this article on how to unmount hard drives when they are not in use. Or, you can just buy a cool App called Mountain to manage your drives. There is an article on the Mountain App on this blog.
