Hard Disk Monitoring

Is it possible to configure HDSentinel to use the default maximum windows platform timer (15ms) resolution rather than its current/default resolution of 1ms? This would be great for power consumption and efficiency as requesting use of the high precision timer when its not needed is wasteful. Other real-time monitoring software use the low precision timer (15ms) without issue, it would be great if HDS did as well.

The default platform timer resolution is 15.6 ms (15625000 ns) and should be used whenever the system is idle. If the timer resolution is increased, processor power management technologies may not be effective. The timer resolution may be increased due to multimedia playback or graphical animations.

Generally the highes possible precision used to provide accurate real-time performance data and values on the "Performance" page.
For this, yes, Hard Disk Sentinel uses the high precision timer in order to calculate the numbers correctly.

The idea you wrote seems interesting and would need to examine the possibilities, discuss the details, so please contact in info (at) hdsentinel (dot) com

Same issue here

HDSentinel is run as a windows service with no GUI interaction.
The only job here is to periodicaly read S.M.A.R.T. data and alert me on issues. For this use case, it is not necessary to diminish power efficiency of the whole PC (turned on 24/7).

I would like to be able to, at least, choose for myself if windows default timer resolution should be overrriden.
