Newbie Question about broken PCB

[joe1203]

I got a SATA HD with broken PCB.
I wonder if it is possible to replace that broken SATA PCB with PCB obtained from a PATA/IDE HD of the same size, same series but different P/N and firmware version.

Even if I can luckly find the pcb with the same P/N and firmware version, the P-List and G-List on the chips are different, so how many chances can I recover all data?

Any ideas/comments are welcome

Need more info at least Manufacturer and Model number.

Firmware lives on the platters, not the PCB.

Hi

1. The defect lists are on the platter, not in chips.
2. The ata layer usually in the SA on the platter as well, so usually you can't use different type pcb with different if.
3. The most of the modern pcbs have internal calibration data, wich can be dangerous for the data in another HDA even if you only want to read it!

So, don't do it.

Thanks pro!

The broken HD is 5ea9ate 72OO.7 Sata HD

Before, I thought SATA/IDE type HD differ from the PCB only. I believe that I can swap the any PCB of the same series.
But it seems that I am wrong. The IDE PCB Swap trick won't work


How about if I am so lucky to get a SATA pcb with the same P/N? Can I swap the pcb?
Or I still need some tricks to clone the internal calibration data to the new PCB?

You need a PCB with the same P/N, same f/w, same config code and same site code.

Even then it might not work, and you'll have to move the ROM chip over.

I assume by "broken" you mean physically broken, or are you just guessing that the PCB is bad because your drive doesn't work?

Or send it down to me, depending if you need your data or just to try and repair the drive.

Correct me if I am wrong, if the firmware is on the platter instead of pcb, is it necessary to have PCB with the same f/w?

[ccc]

A small part of the firmware is on pcb and the other big part is on platters...that's why you should match the f/w...

[pcimage]

The vast majority of the f/w IS on the platters, but the small starter piece of the f/w on the PCB must match the rest of it on the platters.

Pcimage have right.
Why do you think, your pcb is the problem?
It is physically damaged?

Thanks all

It seems very difficult to get a completely matched pcb.

Some PCB reseller claim that any pcb with the same chips and layout can be used for data recovery, is it true?

[joe1203]

Since the pcb smoked

hi everyone i got a hdd seagate barracuda 7200.10 250GB that has two components broken but my machine detects it. and i want to fix it by changing the broken components
the hdd details are:

SEAGATE barracuda 7200.10 250GB SATA
S/N: 9QEOMJJ6
ST3250820AS
P/N: 9BJA3E-305
FIRMWARE: 3.AAE
DC: 07187 SC: TK

if anyone can help me, send the pcb to
my mail is adriandusicka@hotmail.com
thanx

With proper tools, if the PCB is physically identical, and the problem with the bad drive is the pcb, and you know what you are doing, then sure.

[pcimage]

Some PCB reseller claim that any pcb with the same chips and layout can be used for data recovery, is it true?

Yes, but usually not "straight of the box". PCB ROM modification is nearly always required.

Additionally, think about the sellers wants to sell, not else.

Thanks all!

So that means even I have one physically identical PCB, directly replacement is still not feasible.

There is another rumor that Seagate PCB can be swapped if "the second and third character of serial no, whole model numbers, whole site code" match. P/N and Config matching are not required.

Any idea?

[joe1203]

Any idea?

[falther]

This was your conclusion and its correct:

It remains the same answer, even if you go into more details.
