I just finished the process of adding 8 new Seagate Exos 20TB drives to my TrueNAS core system. This question has been asked a lot and it’s known seagate drives are loader then most durring operation. Though i could not find anything related to a consistent “shudder” through all my new Exos drives. I have attached a audio clip in the link below. Have any of you come across this specific sound before.
The drives are in a Fractal Design 7 XL case with rubber bumpers in all trays. The case hold 9 WD Red’s 12TB, and 8 Segate Exos 20TB. All 17 drives are connected to a SAS 9305-24i in IT mode. Running TrueNAS Core 13.0-U5.3

I haven’t heard that one before. I don’t have an answer for you but I have some questions. Is there any drive access when it’s doing that? Are you sure it’s all the drives making that noise not just one? Are they all doing that shudder at the same time? Is there any firmware updates available for the new drives? Is there a firmware update available for the controller? did you run smart tests on the drives?
