Yesterday i was discovered the source of that disk noise i was hearing at nights every 2 seconds, and that was hwinfo. I tryed to disable drive scan (settings> safety), i disabled monitoring of all hdd related parameters, set polling period of disk SMART to 10/60/999, all these actions didn't help, i still can hear this clicking while hwinfo is running. I even tried to disable monitoring of all possible parameters, just to make sure i didn't miss something, and still i can hear it. When i change global polling period, frequency of disk clicking is changing too, so it is related. Is there any way to make HWinfo to stop scanning the disk? Also, debug mode is off and HWinfo is installed on SSD.
