You should seek help from a pro, you need the ROM.

unfortunately in my country i'm a one, in here there is no community like this, no one helps others, but some..

so i need to know SPI ROM Model, just in case i found it..

Nor problem for ROM same pcb with firmware same as your drive would work .
One more thing can u check again for fw i think it should be 3.02 .

no is is firmware 3.2. i got a pcb from 40 gb IDE one, put the board, not detecting,
shit man, modern HDDs are full of crap, i love old quantum drives, single pcb fro series of hdds, just like cpus, man.. modern hdds are more complicated..
