How to hook the drives from a blank driver?

NTFSD
1

Hi All,
I want to know that how can I hook the hard drive or get the handle to device objects of these drives in my blank driver?What are various ways in which this can be done?

2

‘Hooking’ is bad. What is a ‘blank’ driver? Since this is a file systems
newsgroups, there are no device objects at the file system level that work
on disk drives as they are volume type devices. Look at devicetree and see
how the system stacks all the objects and devices. The disk utility from
OSR also provides a lot of info. It may also help if you describe what you
want to accomplish. File systems stop with the FSD. That there exists or
may exist a storage device below is of no concern to this newsgroup.
Questions below the FSDs belong in ntdev.

Basically I want to get the handle of the device object of logical drive(C) using KLowerDevice class?
What are the different ways to get that?

Thanks & Regards,

Get the filesystems book, read it, and then come back with questions based
upon some understanding of how file systems work. There is no device object
for logical drive (C). I also see no indications that you tried my
suggestions. You can add winobj to the utilities to try and see what is
revealed that pertains to your questions.
