Mounting a FS on a readonly disk : how to?

NTFSD
1

i have written a disk filter driver
that makes the disk (non boot/system) read-only.
but doing so wont allow me to view files on
the disk as the FS does not get mounted.

  1. how can i “fake” the writes from a filesystem?
  2. How can i figure out from the irps that the request
    originated from the file system stack.
  3. is there a better way to make a disk read-only with the FS mounted
    and driveletter assigned?

TIA

NTFS can NOT be mounted asd read only. You must use a disk filter and fake
the writes to disk.
