I had my old C: HHD drive replaced by an SSD, and moved to D:
A new copy of Windows 10 was installed by the computer shop.
Although I never used my D: drive since then, Windows 10 reads it upon waking from sleep for a few minutes - even when the drive was disabled and the drive letter removed as an attempted solution.
Perfmon /res (and other programs which show Disk IO) show no IO happening on the drive at all at the time it is thrashing.
I'm driven to distraction by the noise.
I've tried watching tasks' IO in Task Manager with nothing running to see which has any IO at all at the time, and the only potential suspect I can see is csrss - but that could as easily be pure C: drive IO.
Any ideas, anyone?
