I have a TS-253Be NAS with 2x HGST Ultrastar 7K6000 4TB in RAID 1.
I was a very happy user until the HDDs started what I consider BMS. From then, I lost my patience waiting for the noisy HDDs fo finish the BMS scan.
Restarting the NAS produced no result so I started to dig the forums in order to find out and than to shutdown the BMS.
So, I managed to install SmartmonTools v6.5.0 from qnapclub.eu and with the help of putty, I find out:
[~] # smartctl -a /dev/sda
smartctl 6.5 (build date Oct 22 2017) [x86_64-linux-4.2.8] (local build)

Well, It's obvious that my HDDs have smart capabilities but how can I manage to shutdown the BMS?
Maybe because of RAID 1, the result it's consistent? Anyway, I see only one HDD, and not the second one, too.
Please advise, I starting to believe it was a mistake using datacenter HDDs in a personal NAS!
Thanks in advance.
PS: Disk Health from Storage & Snapshots reports some SMART data but nothing related to BMS or Offline surface scan bla-bla...
