there seems to be a problem with the DrivePool service (directly or via WMI) periodically querying drives (even non-pool drives) for some information, thus preventing them from going into standby mode.
The queries happen in a 5-second interval (when looking at WMI) or 15-second interval (when looking at the DrivePool service itself).
They actually show up as I/O activity in for example StableBit Scanner or Process Hacker/Explorer or even just Windows' Task Manager.
If I stop the service, this behavior stops (both WMI and direct queries disappear) and drives spin down as intended.
What does the service even do? It does not seem to affect pool operation at all. Granted, I'm really only using the basic pooling feature, no duplication or anything else.
Versions:
Windows 10
DrivePool 2.2.0.649
I've attached a filtered (DeviceIoControl operations only) SysInternals Process Monitor log showing the behavior:
