Lima Ultra HD appears to be running all night unless I disconnect it (all files already encrypted).

Anyone else experiencing this issue? It's in my room when I sleep and I can see the HD light constantly on and can hear the HDD spinning the entire night. My files were encrypted a long time ago and I can see that no other users are connected. Have to end up unplugging it to make it stop spinning. I imagine this will burn out the HDD pretty quickly.

Any help?
