Disk 0 (C:) missing from Task Manager Performance Tab in Windows 10

In both Windows 10 and Windows Server 2012R2, I am missing my C: drive (which is Hard Drive 0 or Disk 0) from the Performance tab in Task Manager.

This used to work with Windows 8.1.

Disk 0 (C:) missing from Task Manager Performance Tab in Windows 10

Comparison of 8.1 (left) and 2012R2 Task Managers, on 2 different systems. They both have a C: drive though.

How can I configure the Performance tab to also show information for the first drive?

Update: Waid Johnson's answer worked well for one of the systems I am looking at. The system that is not working has Intel Rapid Storage Technology enabled, and there is a cache on Disk 1 that caches Disk 0.


Try giving this a shot:

Ensure Task Manager is closed.

Launch the Command Prompt using the “Run as Administrator” option.

Enter the following at the Command Prompt:

diskperf -Y

Hit Enter.

Close the Command Prompt.

Re-open the Task Manager.
