Hi all! Respectfully I want to ask if anyone can point me on the right direction: I have one Seagate Barracuda 7200.11 ST31000340AS recertified. The PCB is dead and the disk doesn´t spin (TVS are both OK). I get a donor, same model, same firmware and nearly same date.

I want to know if I only need to swap firmware chip (Winbond) or if I need to do extra job. Also I have a doubt about which chip has the firmware. I also have PC3k available. I include photos here.

Thank you in advance.

That's the right chip, and yes you 100% MUST switch this chip if the original PCB cannot be repaired by you.

be careful with the swap, if you damage that chip the recovery will be pretty costy...

Very true, have seen a fair few "bodged" chip swaps which have proven to be very costly indeed :-(

Thank you very much for comments. Chip swap was successfully. I can see disk onto PC3k (wrong size). After load it on utility everything were OK and I can copy data. Best regards!
