The smooth chip got burnt when i plugged it into a wrong adapter. Worked fine prior to this.

Any ideas where I can find one? Also will I need to transfer ROM data and any tutorials around here for that

Photos of front and back to the hard drives are attached to the post!

The pcb is : 2060-701474-004 and does NOT have a U12 chip.

Does anyone know how would I be transplant the ROM info if I get a new pcb?

The adaptive info that you need to transplant lives on the main controller chip I would imagine. Pro tools are needed to transfer. I seem to remember ppl recommending a place that supplies the pcb and swaps the rom for you. Onepcbsolution.com or somethinl like that. Never used them myself.

Try this vendor:
http://www.hdd-parts.com/firmware-transfer.html

He normally charges US$70 for a PCB, including firmware transfer.

I am assuming pro tools are a heat gun and good soldering skills?

No, pro tools meaning software tools to move the adaptive info from the one PCB to the other. There's no simple U12 swap here, the info that needs to be swapped across (that's otherwise stored on the 8-legged U12 chip) is stored on the main controller chip. Not a DIY job.

I thought the MCU can be removed and moved to the new PCB using a heat gun, it seems to have many legs but wont a heat gun transplant suffice?

Also what software is needed to transfer the MCU adaptive data? Just curious

No software tool like SD WD DR or ACE UDMA something like this can do the job for you on it. Other than this a Pro service can do it for you also that means taking it to a DR company and having them move the adaptive data over to the new PCB board and recovering your data.

So again why can't a person desolder and move the mcu over to the donor pcb?

If you have experience with this kind of soldering work, then you should be able to do it. However, be aware that the SMOOTH chip controls the DC-DC converters that supply the Vcore and Vio voltages for the MCU. I have seen at least one case where the the MCU's core was damaged. IMO it would be easier to replace the SMOOTH chip and repair the DC-DC converters, if necessary.

UNFORTUNATELY the chips are not "easily" available, and the unique easy way for "average joe" is to get from other working PCB but again you have to SAFELY move the chips.... And still the state of preamp is unknown. AND you don't have schematics . AND ...

About "So again why can't a person desolder and move the mcu over to the donor pcb?" the answer is simple : 40 years ago the man went to the moon, but you can't call ACME and make a rocket unless you are Wile E. Coyote .

So, unless you have the proper equipment , it is not easy (less than less if you have to deal with BGA chips, despite all youtube videos and tutorials) AND it is risky. At present, assuming there is no internal problems, the whole thing is simple to fix even if the entire PCB is fried completely - of course by PRO.

Read also these instructive threads about DIY, and decide if it is worth or not - nobody will guide you step by step and even if you were encouraged to DIY the risk , the fault, loss of data or the happy end is only up to you. It is very different if you ask a regular legit professional to try to rescue your data.
