help pcb WD 006-0b40829

[magnetepazzo]

Hi Guys, a customer brought me an 8 TB WD hard drive with the following pcb 006-0b40829. The motor does not spin, it is possible to hear a small noise as if it wants to start but it does not start, in MRT it remains in the BSY state, removing the pcb and leaving it alone it remains in the BSY state. According to the client, the problem arose after a small bump. Suggestions?, Thanks

Stiction?

removing the pcb and leaving it alone it remains in the BSY state.

sounds like bad PCB

[DR-Kiev]

Spindel stuck, which can cause to motor-chip death additionally.

Hi guys I think it's bad pcb, the motor it's free to spin, no lock, suggestion for repair ? any friend have a schematics ? Tks

[pepe]

pcb swap with rom swap?
However, i would check the heads for bent suspensions first.

Hi pepe, it's the first step for me, I have open the cover and have checked motor, if are locked and head. I haven0't this pcb and have thinked to repair

I have open the cover and have checked motor, if are locked and head.

Isn't it a Helium drive?

[michael chiklis]

Not all 8 TB are helium filled.
Example:
WD80EFAX-68LHPN0 - helium filled model
WD80EFAX-68KNBN0 - air filled model

If you can provide a better photo (with a CCD scanner ?) I could identify the voltage test points. That said, I suspect that the motor controller may be faulty.

And what PCB number is on the air-filled drive?

It would appear that the OP's PCB is used in the WD80EZAZ-11TDBA0, which is a HGST helium model. I don't know whether the same PCB is used in air models. If not, and if the OP has an air drive, then could it be that the customer has replaced the PCB?

006-0B40829 on the PCB

I recently got a few WD80EZAZ-11TDBA0's. These appear to be WD White label "Ultrastar He10-8 (US7SAL080)", smartctl seems to detect all except one property: "22 Unknown_Attribute" If I am not mistaken that should be the Helium sensor.

The date code on the PCB is 2419, week 24 of 2019.

That's why I'm still waiting for my answer about the drive HDA type

Update, hi friends the i have take same pcb from 10 TB HDD and have swapped rom, now the disk spin normally but don't work, i not heard noise from head positioning and i think the pcb are locked. I have connected the unit to original usb drive (it's a mybook drive) but nothing. Suggestion ? TKS

Since you already opened the drive, you can throw it to garbage now.

[magnetepazzo]

from what you write it is clear that you have not understood anything!

clearly

[Doomer]

ok, I'll make it easy for you
The drive does not unpark heads because either heads are bad or because there is no Helium inside the drive anymore.
Since you opened the drive I would think it's because of the latter.

Basically you killed the drive for no reason. You can tell that to your client.

Check smart under Victoria

If smart is detected then try to read hex sectors in r-studio (drive must be connected in the original enclosure). If you see only E5 pattern then you have same issue as me.

I had a similar case and i came to the conclusion that translators are damaged.

At the moment there is any solution yet.
