By default, disk performance counters are not started. Therefore, almost
all of the disk metrics obtained will be zero. To enable the disk
performance counters, execute the following command and then reboot the
system:

   diskperf -y

DISKPERF.EXE is located in %SystemRoot%\system32.

The decision to avoid starting disk performance counters by default was
made for performance reasons.
