ok here goes I have a ST320410A 20 gb with a bad control board ,( firmware 3.34),and i have another one that is dead with a good control board (firmware 3.39) could i , and if i can ,how do i install the 3.34 firmware on to the 3.39 board.

Hi

I really had to dig deeply in my inventory to check this model, so a picture of the 2 PCBs would help to decide what to do here. If the board topology (processor type, motor Combo, reading channel IC) matches, u can change flash ROM ICs.

Dear : Pepe

It is true
processor type : ST 100167669; motor Combo : SMOOTH 100143434; flash ROM ICs : Windbond W49L102Q-70; reading channel IC : NEC SINGAPORE C2164GC

Thanks

Hi,

As i mentioned if everything matches, u can replace the ROM from the burnt board to the good one (provided it is intact of course )

I need one advice for one situation.

I have one hdd ST94019A FW:3.05 SN:3kw3zyy3 which need to be changed the MHA and from 2 months I try to find one fully compatible HDD for changing MHA but all I find was just hdd ST94019A with firmware 3.07 , 3.04, 3.07 but not 3.05.


What I can do in this situation ?

3.04 or 3.07 will probably also work.
