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.

I wouldn't buy that PCB from that guy at eBay ....

When i did check there was a note saying one sold on the past hour so i hope it wasn't you who did buy it ...

Look at the feedback :

Looks like the guy did send BURNED PCBs (with VISIBLE burning marks) to many people and did send some PCBs missing components to other guys as well ... His feedback rate is very low and he does have a huge amount of negative feedback ...

You will end up without money and without PCB ...

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.

Are you sure that the PCB is damaged ? Are you sure you do have a problem with the smooth chip ?

Does the drive report any status register ? Some of those He filled drives will not spin if the sensors do detect that He is gone ...

You might like to measure some voltage test points:
http://www.hddoracle.com/viewtopic.php?f=21&t=2549&p=20304&hilit=OA90439#p20304

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!

Those drives are very new and no-one is willing to recover from them even more because there is no PC-3000 support, etc ....

No one had done huge research on those and they are expensive as well so no one is going to buy a huge lot of those to damage them by opening and experimenting with He, etc ....

Most likely the initial issue was not related to PCB at all ...

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.
