Can’t see the disk performance in task manager on a Windows Server?
There is multiple factors for disk performance not showing up, including raid cards, the server being nested on a HV or running as a VM, there is a simple quick fix though;
Open Elevated Command Prompt
Start disk performance counters:
With any luck, that should be it now showing in Task manager, if it does not, close and re-open it for the disk performance indicators to appear.
On occasion, you may need to re-install/install the latest raid card drivers if they are missing in order for the disk performance indicators to read and run correctly.
