Attaching to disk driver or fs

NTFSD

Hi,
what is difference by attaching to a disk driver (between disk and FS) or
layer itself on top of FS?
For layering itself on top of FS is only necessary to implement
FastIoDispatch?

Hi,

When you attach between disk and FS, you receive information (on IRP) about
physical access to disk(Read/ write sectors). When do you attach on top of
FS, you receive informations about FS (File access, file name, etc). Do you
nees implement FastIoDispatch only for FS attach driver.

Hi Heldai,

I am bit confuse.
I want to attach my driver in middle of disk and FS. Does I have to attach
my driver to all partitions on the disk.

Thanks

Ashish,

Yes, if you want to filter between the file system and the media, you must
filter each media device object on which a file system exists.

Yes,

Tony Mason already reply to us.

You will need load your device driver before volumes be mounted (Start = 0)
