Why are my NAS hard drives not entering standby mode?

Hard disk standby mode can be enabled in "Control Panel" > "System Settings" > "Hardware". If this function does not work as expected, check if the following applications/services are running.

  • UPnP.
  • NTP server.
  • Container Station
  • Notes Station
  • BT downloading.
  • Microsoft Networking: AD service, WINS server, Domain Master.
  • Shared folder mapping.
  • Network access to the NAS. If your NAS is connected to the Internet, make sure you do not enable DMZ or port forwarding on your router/firewall. Hackers may attempt to connect to your NAS and prevent hard drives from entering standby mode.
  • Qfinder Pro, Quick Install Wizard, and NetBak Replicator routinely check for your NAS on the network and will prevent hard drives from entering standby mode.
  • QmailAgent routinely accesses and checks email accounts to synchronize and back up emails. This will prevent hard drives from entering standby mode.
  • If virtual machines are running in Virtualization Station then hard drives will be unable to enter standby mode.
  • If you have recently moved/saved a large number of files to your NAS, these files must be indexed. Your NAS will also create thumbnails for newly-added media files. The indexing and thumbnail creation process may take a long time to finish (depending on the number of files) and hard drives will be prevented from entering standby mode during this time.
  • If your NAS is shared with multiple devices on the same network, any access to the NAS from one of these devices will prevent hard drives from entering standby mode.
  • Some apps installed from the App Center that routinely access your NAS may prevent hard drives from entering standby mode.
  • Using a USB Wi-Fi dongle to connect to a Wi-Fi network via an access point may prevent hard drives from entering standby model.
  • OceanKTV routinely synchronizes the recommended playlists from online databases and may prevent hard drives from entering standby mode.
  • Mattermost

If you still have problems, you can connect to your NAS using SSH port 22 or telnet port 13131 and issue a ps command. This will show all the running processes.

You can also run a diagnostic program to discover the processes that access the NAS hard drives:
