How to add a file header ?

NTFSD
1

I’m a beginner in writing filter driver using Filemon (from SysInternals)
as the base for W2K. I want to write a proprietary header in IRP_MJ_WRITE
and get back the header in IRP_MJ_READ. I want to place the header at the
beginning of file.

How can I do that ? It would be more comprehensive to me if you can explain
with actual codes.

Thanks in advance.

It is a great idea to have the header which is exactly 1 page in size.
After this, filter the low-level uncached IO and adjust the offsets.
