Hey again, so yeah, I gave it more then 30 seconds, I even closed my browser and waited 5 minutes then came back and it was still updating every minute, I was taking a look into that indicator in the "Main" tab. Thanks!
Edited: So I have uninstalled the plugin, installed again, then quickly changed the Refresh Interval to "No Refresh" and it now is working as it suppose and don't spin up my disks up anymore.
