WD20EZRX-00D8PB0 Burnt PCB Swap

August 13th, 2018, 21:20

Hi, new to forums, sorta new to DR (but will seek answers) and I have a drive that was on fire, and from the looks of it for a couple of seconds atleast.

the issue i am having with it is i am unable to get a rev number, as the board has been chunked out where it would normally be.
the board is a 2060-771945-001

so the main question is what boards are compatible? if someone has a chart they could point me at that is great, as i dont want to take stabs in the dark.

also i do not have a pc3000, only deepspar

here is link to pictures

You have bigger problems than the REV #.
REV is not important.
The damage is extensive and has probably affected the drive on the inside.
Plus, your pcb does not have an external ROM chip, thus you can't simply swap PCBs by transferring ROM chip.
You would need to hotswap it to read SA and find version number/build ROM from SA. This, assuming platters are ok. And I dont think you can do that with a DDI.

I think someone skilled should examine this drive in a clean room before anything else.

I thought u12 = rom?

and the platters are okay, and if I am correct in thinking the u12 is rom (will clean and check) then I have it and does not appear to be damaged.
and i should explain this is for my own adventure, I am just trying to learn, there is no customer data loss at risk, or personal data at risk, this drive is from a customer who opt for no recovery and gave permission to use it for training and testing.

I’d be VERY surprised if the preamp survived in this case.

the preamp is unknown, but i do know the drive was mounted top down, so i am slightly hopeful, i am just at a stand still atm as this type of case is new to me.

So you opened the drive and checked platters?
Did you remove U12?

On occasion I found plates where the revision of the plate did not work for me.

Specifically for a USB PCB change
2060-771820-000 REV P1 worked for me.
2060-771820-000 REV A did not work for me.

In this particular PCB some sellers ask about the amount of capacitors that are in the box that I have marked with a 2.

yes and yes, and the ROM visually looks undamaged, but i dont know to much on how i would test that with the tools I have.

That's going to be interesting as that is an area that is badly burnt, but that is info i can start doing some more research with.
