Hello,
i've this hard drive with faulty pcb:
WD80EZZX-11CSGA0
P/N: 2W10100
PCB Revision: 0A90439
PCB Sticker: 0J35276 BA5145B

this is an HGST helium drive, pcb has damaged SMOOTH L7229 chip.
I can't find this pcb anywhere, could any of you kindly lend me this PCB or at least help me to find it?

Thank you.

Ohh, that user on ebay has a lot of bad feedbacks
I also did try to search this pcb on ebay by inserting "0J35276" and "BA5145B" as key words, it didn't show me any result.
Without your direct link i wouldn't have found it, but i want to give a try.

Thank you again.

Yes it was me, i know i'm risking with this guy but as i said i wanna give a try.
I can't find that board anywhere else.

I'm curious. Where is the damage to the SMOOTH chip? Are either of the TVS diodes shorted?

No Frank, TVS diodes are not shorted.
The drive just doesn't spin, it's completely silent.

You might like to measure some voltage test points:

I expect that you would have checked that PUIS was not enabled ...

This hard drive came here with no power on issue (it was completely silent).

I thought pcb was faulty so i did some test...
First i did power on under MRT, ID was correct and DRD + DSC registers where green.
Then i started to do some signal checking with multimeter, see pics:



After that i power off and went to have lunch, when i came back to continue with further test, smooth chip smoked right away when i powered on.

I know but is too expensive the entire drive, customer doesn't want to spend so much.
If i can recover just with pcb swap that's great, otherwise he doesn't care as much about data inside.

How do i know if this drive is one of those?
What can i do for recovering data if sensor already detect that helium is gone?

P.S.
First of all, at this point, i've to replace pcb because now it's sure that is damaged. I don't know why this happened!

There is a great chance it is spindel stuck issue

If pcb works good, in case of spindle stuck, should i be able to listen a bip sound with a hear next to the drive?

I received 2 of these this past week. WD80EZZX-11CSGA0. In both cases there was no spin up. Was able to recover both using a working PCB(ROM swap). PC-3000 does't recognize the family so i had to just pick another family from the WD 3.5 group. No issues in DE.

According to the OP, the drive is a HGST helium model, so which WD group did you select?

I used Giant2. like I said it was a random pick. No particular reasoning behind it. Since PC-3000 doesn't support the drives you cant work with SA yet.

Could it be that a stuck spindle is the reason that the motor controller failed?

We had a 16TB My Book Duo with 2 of those 8TB WD Helium HDDs in. Both no spin.

The techs at the IT company it went to first took the drives out and tested them. They said they were not spinning as well, but not sure if that happened naturally within the external enclosure itself or maybe it was a mess up during testing.
No visual physical signs of any burns on the PCBs.
Some brief preliminary voltage testing checked out fine. Nothing apparent being suspicious.

Good donor drives we ordered spun right up without issues in case a PUIS or anything weird was configured on them.
Replaced PCBs on each drive with ROM swap and got the patient drives working again.

Was a new enclosure really necessary? Did you test the original bridge PCB?


There is no need for "advanced" software. Just about any freeware SMART tool will do this.


So you mounted the customer's data on a Mac OS, and then copied the files to an external drive? Where did the "advanced" software and "advanced" hardware knowledge and "advanced" tools come into the picture?

ISTM that this was potentially a very simple DIY job.
