Hi I'm desperadly seaching for a replacement PCB for my MacBook Pro's HD. It stopped working abruptly, never made strange noices, nothing.
The drive does not make any noise (not running) at all.

I had another drive also a momentus 7200.3, but a ST9320421AS, I replaced the PCB, and connected it again to my computer. Now the computer detects the drive again, but does not recognize any partitions, or size of the drive.

As I understood now it is important that the PCB has the same version / firmware.

So this is what i'm looking for:

Disk : ST9320421ASG
SN: 5TJ0GVBY
PN: 9GEG44-040
FW: AP15


Is there someone who can help me out, has some suggestions or links where I might get lucky ?

Kind regards, Rene Reuscher

Hello,

No, your experience is incompleted.
This pcb has UNIQUE adaptive data inside, so you can't simply replace it.
If your data is important, i suggest to seek for the local recovery company.
If you are right, and only the PCB was the problem, and you have the another pcb what have you tried allready, than this case is cheap.
But if there is more problem, you can't solve it alone....
This is not a DIY case.

Janos

Janos is correct.

The ROM contains unique information, even down to the serial number. So it's impossible to simply swap the PCB in this case, don't waste any more time or money on looking for a non-existant PCB.

I can help if your willing to ship to UK and pay a reasonable charge.

Or anyone here from Holland?

Hi,

First thanks allready for the quick replies.
I also have been told that replacing the PCB, and toggle then the 8-pin EEPROM ( which it seems, contains the factory callibration data ) could probably help in this case. Assuming that the EEPROM is not fried on the broken PCB.
What is your opinion about that ?

Regards, Rene

Yes, if your pcb have external EEPROM, this should be enough, if you have found the same pcb for replacement.

Rene did you ever manage to get this issue sorted? I've got the exact same problem and wondered if your new PCB worked out of the box or if you indeed had to change the EEPROM?
