Move the Main Controller IC (the biggest chip on the board)

[Gumby8888]

I keep seeing this in alot of post "Move the Main Controller IC (the biggest chip on the board)", but does that mean a DIY cant do it?

The number on the green part of the Original board is 2060-701537-004 REV A. On the White label it is 2061-701537-R00 AD. It's for a WD7500AACS-006B0 External drive.




I need this kind of swap to make my HD work again to get the data off but I havent seen anything on how to remove the chip.

My issues started back in Feb when my drive wasn't found in windows so I opened the enclosure and separated the drive from the case and plugged it into the Motherboard sata connection. still no sign of it in windows and the drive wasn't spinning.

So I contacted Datapro and they had me to send them the pcb for repair and I think they finally finished off the pcb. After 3 months after being sent out the pcb is burnt up and still doesn't power the HD (wont spin)


In the mean time I got on the ebay and bought another drive, thinking I could just swap the pcb's and get my old HD to work. The numbers on that board are (2060-701537-004 REV A) (White label 2061 701537-R00 AD XC 6Q05 8EXN M 0002060 9062) and this drive is a working drive and windows finds it.

So I swapped the pcb on to my old drive that I want the data off of and the drive will spin,but it isn't found in windows.

So then I found out that the bios might need swapped from board to board to make it work, but I ran up against the Main controller swap problem and I don't see a way for me to get it off to try it.

I've tried searching google and this forum and also youtube to see if I could find a demonstration video on how this is done, but I havent found anything yet.
So now I'm asking to see if anyone could offer any help in this?
Thanks

Just a question - all the charring of the PCB around the controller chip, is that how it came back from the repair service? If so that's just an attrocious job, it's like someone with no clue hit the board with nothing more than a household paint-stripper/heatgun for far too long without any protection to the parts around the chip. Sure looks like the board is completely dead now!

Can you provide a larger version of the burned photo?

This model has no external ROM meaning the native ROM can be restored from the SA without the need for a repair of the native PCB.

Do yourself a favour and send the entire HDD, not just PCB, to a reputable firm who can handle it safely for you. As far as DIY goes, assuming there is no other problems, the process of restore ROM from SA is relatively straightforward, but requires specialist equipment and knowledge of the process. Also, there is always the possibility of other complications which can be addressed directly by a professional.

HDDZone are hitting all the storage forums. That's where the "Move the Main Controller IC" advice is coming from.

http://www.hddzone.com/faqs.html

Code:

1. Can you advise the firmware code of your board?
We can't confirm the firmware code with you. In most cases, you should move your original PCB's BIOS/Main Controller IC to the replacement board.

Code:

10. What does this mean "This PCB's BIOS is integrated on the Main Controller IC. You should exchange the Main Controller IC to let the HDD be recognized"
It means you should move the Main Controller IC (the biggest chip on the board) from your original PCB by using hot-air gun, and then solder it on the replacement board. Move the Main Controller IC is a complex job which need you have certain technique. Some electronics repair shop can do it.

Here is the kind of thing that the professionals actually do:

Fix Identification Problem caused by Corruption of ATA Overlay module or ROM content:

As you can see, it is essentially a simple, non-invasive job. You can purchase the software for much less than the cost of a typical data recovery. There is one PCB supplier who purports to provide a free PCB adaptation service, but I would feel remiss if I didn't alert you to the following threads:

Dammnnn.. I bet there's all kinds of delamination and maybe torn vias in there. At least the local electrical and high-frequency characteristics will have changed.

I can do better with a safety pin and a $10 iron from radioshack! And I kid you not! heat each pin, and lift a fraction of a mil. Repeat 99 times as you work around the chip.

Of course that is no substitute for a solder pot or temp controlled airgun with shields and airflow guides and all that.

Exactly which company did that, what's their website?

[Doomer]

BGA chips are a little harder to move because you usually need two sources of heat (top and bottom) and decent amount of practice.
Sometimes (preferably always) the chip needs to be re-balled (new pads of solder applied) before you can solder it on another PCB and you'll need special stencil for that
And w/o practice it is very high chance to damage chip pads while taking it off the PCB. That will damage the chip permanently.
Bottom line is - the cost of proper tools(and no practice) will be more than the cost of moving the chip to another PCB at the place that specialize on that kind of repair.

Keep in mind that the chip might be already dead and all that could be for nothing.

I can't see the soldering work around the SMOOTH chip. The image is too blurry. I get the best results with a flatbed scanner.

I would compare any discernible part numbers against those of a good PCB. Maybe the wrong SMOOTH chip was used?

I tried what you said with my flatbed scanner but still the chip is unclear for me to post.

Also I got you pm, but can't reply yet because I'm too new to the forums. TY for your advice.

Contact scanners can't scan 3D objects.

Well, I know one place I won't ever be asking to do work on my boards for now! For the record, I do SMD reflow work here, though mostly I'm manufacturing assemblies rather than repairing them ( I repair a few since not every initial reflow works 100% and you have to manually redo it ).

What bothers me in this case is that it was "only" a TQFP chip, which are fairly easy to remove and replace - possibly it has a ground plane contact on the underside but even still the damage done to that board far exceeds what needed to be done. It's scary what "professional" services can get away with.

There is a chance that SMOOTH chip is not the problem or not the only problem
But anyway, ROM is inside Marvell chip, not SMOOTH chip

Agreed. Especially all the little problems that are easily dealt with hands-on. If DIY succeeds and doesn't become DIY then congrats and a tip of the hat.

IIUC, the OP had an unspecified problem with the original PCB. Unless I'm mistaken, "Datapro" determined that the SMOOTH chip was faulty and replaced it. Either something went wrong, or the diagnosis was incorrect, so now the OP has purchased a donor PCB and is contemplating transferring the MCU from patient to donor.

If the OP is prepared to make a few measurements, I could help determine whether this process has any chance of success.

I challenge anyone to get better results with their camera.

[Keatah]

No need to challenge. Your scanner is not a cmos-contact scanner. It is a CCD based scanner. Completely different optical system. Not to mention a better quality detector array. Less cost cutting too.

Dear Shalom tsophia,

You can try board first,

We do have the same board as yours:

Total cost = $49.99USD (board+ firmware transfer+ shipping)

They are same PCB boards, but the board BIOS IC exchange is needed. Why ?

Because, for this model hard drive, each PCB BIOS IC is programmed by the unique original hard drive configuration data.

We have to copy this unique configuration data to the donor board and then the donor board will be compatible with the original hard drive.

We have two options for you:

Option 1. We do "BIOS exchange" for you for free, but you have to ship the original board to us.

We do BIOS exchange on failed board with 95 percent successful rate.

Option 2. You do "BIOS exchange" by yourself.

Please let us know your decision by replay this email.

when you ship the board to us,

for Western Digital hard drive ,please go to http://site.hdd-parts.com/WDF.php

Fill and Print the form and ship the Form and your board together to:



our mailing address:

DataPro Lab 528

15216 North Bluff Road

White Rock BC V4B0A7

The post office may ask you to fill the customs form

Please declare your damaged board value at $5 USD

or you will have to pay customs fees

Thanks

Jason

This is the error report I did on this drive in ubuntu. I held the plug in hard to the drive while my son typed on the keyboard using GSMartControl in ubuntu 14.04. The drive only starts to read if the plug in the micro usb plug is held in at a difficult angle using both hands. Otherwise the drive spins a little and then stops. Do you think a donor board identical to this would assist, as it would have a new chip on there giving the motor the correct speed and if there is any problem with the micro usb socket then a donor board would have a new one on it? It doesn't have a repeating clicking like a head stuck on the platter. Here is the test results. And if you think you have a donor that would work with this all the details are in this report, then please let me know so I can purchase a donor from you.

[fzabkar]

The SMART data look good.

It sounds like you may have a problem with a flimsy USB connector. Have you examined the USB pins on the PCB?

Try a USB 2.0 cable. USB 2.0 and USB 3.0 use different signal pins.
