Sample Code for "Storage filter driver"

[ArunAyachith]

HI I am looking for sample code that works as "storage filter driver" either UpperFilter or LowerFilter.

I have used sample code from Visual Studio, KMDF which creates Driver/Device/Queue files.

I am trying to modify the inf as follows.

;;=======================================================


the driver gets installed, but when I try to start the driver, it gives me the following error.
=============================

The service cannot be started, either because it is disabled or because it has no enabled devices associated with it.

=============================


Please help me, to understand what error I am doing.


Thanks, Arun Ayachith.
