Hey there!
I got an Ironwolf Pro 16 TB as a parity drive for my first unRAID build.
When starting it makes a lot of noise, and when running (array not even started) it continously makes a head movement sound every second. I could still send it back. I guess I should, right? S.M.A.R.T. looks good (did an extended test).
I made two videos:
Starting: https://vimeo.com/384354459
Running: https://vimeo.com/384353922 (you see the M1015 LED corresponding to the sound)
Thanks for your opinions!
Edit: so what I gathered from reddit it seems that others' Ironwolf Pros are doing the same thing, but not all of them. I am inclined on keeping it.
