You can limit the functionality of ur writes to all the other sectors except
the sectors that u want to be read only.
For instance u can block all writes to specific sectors on the disk in

…and then get “Lost Delayed-Write Data” error. Bad idea.
Any security-related blocking must be file-level and must work in CREATE
