Installing DiskPerf.sys on disk drive!

[sd]

Hello,

I am trying to install the "DiskPerf.sys" filter driver using
addfilter utility, but everytime I install it on devices listed by
addfilter (addfilter /listdevices), the system fails to boot.

The DiskPerf.sys help file mentions that the addfilter utility needs
to be changed to install the filter driver, does anyone knows what
need to be changed.

I am using the following command line to install the Diskperf.sys as
an upper filter;

addfilter /device \Ide\IdeDeviceP0T0L0-3 /add diskperf.sys

and

addfilter /device \HarddiskVolume1 /add diskperf.sys

Any help would be highly appreciated.

Thanks,

WD
