Hi
i have a ST3500820AS having the busy noise problem.
the customer told me the story of the HDD and send it to me.
he first made a few tries before sending it.
he changed the pcb with another one and he threw away the original one!
Can i find the F/W and clone it with Atola to this PCB?

thank you in advance

the F/W of the Drive is SD25 and the rest of the details:

Date Code: 09096
Site Code: KRATSG

if i get a pcb with this F/W will i have any problems?

That will be a really hard one to get a compatible ROM.
I think your best option would be tell the client to search very well his garbage to find the original PCB

i think that the best thing to do!!

Or else you got 2 options: be able to rebuild original ROM or try tons of PCB's until finding a compatible one.
