Rom Transfer for segate 80GB ST380013AS

[odedshankar]

Hi Guys,

Segate 80GB ST380013AS.
I need to transfer ROM between PCB's and never did it for segate and specially for this drive.
Please find attched PCB pictures, can anyone advise which chips need to be moved?

Thanks,
Oded

I can't advise if any chips need to be moved (I would have thought that a straight board swap would work), but the flash memory appears to be located to the left of the SDRAM. Is it a Winbond IC?

hi fzabkar,

I tried streight swap with this one without luck.
In terminal it gave a message that the flash content is not equivalent to the app code on disk, which means the overlays are wrong.

I'll try to move it.

Guys,

Just out of curiosity doesn't some of the firmware get dumped onto the platters as well, right? I noticed that you just can't swap out controller cards anymore like you did with the old Maxtors. What's up with that?

There is a serial chip where the firmware would be installed and called however I too have a firmware-bricked hard drive. If I could just get the firmware back onto it, install it and allow it to 'reset' I'm straight otherwise, here I am, too. I agree with fzabkar; the left side.

You'll need a burner to talk to it though (or a dongle).
Best luck

Just a general observation ...

Any 8-pin chip that connects to a coil (inductor) is usually a MOSFET, or FETKY (MOSFET plus diode), or a PWM regulator. These are usually wired to the motor controller.

A flash memory, OTOH, is usually on its own, and is wired to the MCU.
