Just bought a new Seagate Ironwolf 8TB drive from Amazon. Currently am writing data to it, but while writing every once in a while it makes this metronome-like noise, it is low-pitched and doesn't sound like the click of a dying hard drive. The drive seems to be working fine right now and smart data seems fine with no reallocated sectors or seek errors.
Should I be concerned? I actually bought this drive to backup a drive that is dying right now so if the new drive is dying too, that could be a big problem.
