stupid question about moving SA to secondary heads

[sin]

Hello, I wish to do something stupid. I know this must have been tried. Please help route me to the correct path my light giving friends and bail me from the dark path.

Some WD HDDs have 4 heads or more. Primarily the SA is written on head 0 and 1.
At times tracks of head 2 (physica, 0,1,2) can be read too and have a different 01 over there. (Was randomly trying to read head 2 of some family drive that i dont remember now and did a tracks to module, DFL found dir mod on this secondary head and tried to generate a few modules from the tracks read just from head 2)

So can i put the working primary SA of such drives onto head 2(physical) and have the ROM fetch 01 from this head?

let me know

If you want me to redraft my question, will happily do that.
Thanks

So formated SA on 0 and 1 and wrote it by tracks to 2 and 3 heads...
no detection err abrt....
Is it something that one has to instruct in rom to fetch SA from the redundant heads?
if so, can some body help me find it?
