Re: filter driver for disk.sys

Hi ,
Actully i have to write on the disk using WriteFile() from my appliction. But in vista it gives error "Access Denied" . So i am trying to control read and write operation in disk using my filter driver so that i can write on disk from my application. I dont known that it will solve my problem or not but i known that kernel mode driver can solve this problem. And that is what i am trying . Also as this driver should work for my application only. I want it personal interaction from my appliction so that no other appliction go through it.
Thank in advance

Hi Don,
Thanks for reply
yes, all the symbols was correct.I debugg my all other driver like this only. But i am facing big problem while handling disk class filter driver.I want to interact to that driver from my user application. But when i was installing that driver from my application at run time( using createservice ) i get startservice fail. so i make an inf file for installing driver where restart is require. Then i am not able to debug it. Also i am not able to communicate it from user application. Do u know any good example that can help mw out.

What do you mean all the debugging options are disabled? Do you have the correct symbols for your driver loaded by WinDBG? Did you try to look at variables or set breakpoints when you stopped at DriverEntry?
