I just bought a new Dell server tower (Poweredge T20), it comes with a 1TB Toshiba hard drive.
I currently have the server connected but it's not being used by anything.
The OS is Ubuntu server 16.04.
The server is not doing anything and yet the drive keeps making noise and is warm to touch.
The sound isn't like the read/write sound. It sounds more like a fan/low wooshy (that's probably not a word) sound. And I'm sure it's coming from the drive because I disconnected all the fans.
What could be causing this?
