After I realize that Performance Tools with Disk Counter not show the
Disk activity, so if the NT Cache or Disk cache is involve with read/
write from disk the Counter show like HD Activity.

So how I can trace the Disk itself?

You have to use Diskperf and reboot to enable the disk counters.

I not see any clue that Diskperf is enable low level Counters? it's
seem that my system Enable Counter, so i'm see results from this
counters, but My q is how get monitoring over low level activity with
no influence of Windows cache & HD cache?
 
Re: how to monitor the Low level Disk activity?

this my output:


Both Logical and Physical Disk Performance counters on this system
are automatically enabled on demand.
For legacy applications using IOCTL_DISK_PERFORMANCE to retrieve raw
counters,
you can use -Y or -N to forcibly enable or disable. No reboot is
required.


like I say to John John, this is not my problem, but i looking after
low level monitoring?
