Symptoms

Consider the following scenario:
  • You install more than 27 physical hard disks on a computer that is running Windows 7 Service Pack 1 (SP1) or Windows Server 2008 R2 SP1.
  • You use Performance Monitor or a Performance Data Helper (PDH) function to monitor the performance of the physical disks.
  • You use Performance Monitor or the PDH function to collect the performance data.
In this scenario, Performance Monitor or the PDH function takes longer than expected to collect the data. Additionally, CPU usage is higher than expected while Performance Monitor or the PDH function collects the data.

Note The time that Performance Monitor or the PDH function takes to collect the data depends on the number of disks that are attached to the computer.
