JSI Tip 4065. 'PerfDisk' Application Event Log error when you run System Monitor?

When you run System Monitor to collect data, you receive 'PerfDisk' errors in the Application Event Log, even though you are not using any disk counters?

The errors are similar to:

4/11/2001 3:24:09 PM Perflib Error None 1008 N/A ACOMPUTER"The Open Procedure for service ""PerfDisk"" in DLL ""D:WINNTsystem32perfdisk.dll"" failed.

You have disabled the Logical and Physical Disk performance counters by using the diskperf -N command.

To prevent the entries from being logged, run diskperf -N or use Regedt32 to navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesPerfDiskPerformance. On the Edit menu, Add Value name Disable Performance Counters, a REG_DWORD data type, and set the data value to 1.
