Hi

I have this HDD with USB PCB wich the client said that it was not recognized and it didn't fell down.
When I plug it in, no spin, no noises, nothing.

I tested with a SATA PCB, still nothing but I ordered 2 new PCB: a Sata and a USB.

When they came, I attach the new PCB's and it spins. GREAT!!!

Wrong: after swaping U12, the HDD doesn't spin. Nothing. I have tried swaping U12 and U14 of the USB PBC and still nothing.

With the donor PCB with it's donor ROM it spins....

What should I do??

Thanks

I have had the same issue with one of these before

Moved U12 to compatible SATA PCB and drive would not spin up. Moved U12 and U14 to working USB PCB, same problem.

You are sure the boards are interchangeable?

this is USB PCB issue
the question is: is it encrypted? or not?

if yes, little headache
if NO, good news and easy to fix

do u know how to KNOW if its encrypted or not? Million $ Q (regardless of asking ur client, do not rely on him)

In the example and job I am referring to on my side, the SATA PCB was definitely the correct PCB, but drive failed to spin up after U12 swap, where as it would spin up with the original USB PCB. I've had this now twice before.

They are the same model, the USB that is.

The original USB: 2060-******-001 REV P1.

The USB Donor is the same model. The SATA PCB is a 7060-******-001.

Even if the drive is encrypted, shouldn't it spin at least?

sometimes this is due to ROM issue, i had many similar cases

Is u12 been soldered 100% correctly onto donor USB board
I just completed 750gb USB drive this afternoon, patient board was faulty, replaced with donor USB board, moved just u12 and all ok

U12 can be tricky to solder so it has to make good contact

I think is soldered OK, because whe I put the donor rom back on donor PCB it spins OK...

small trick with ROM you should notice

USB PCBs are not matched. I have a similar case before.

An example : 2060-1672-xxxx (USB) interchangeable with 7060-1675-xxx (SATA).
You have to transfer U12 only.

Let me clarify my examples I had, 2 times so far I've had this problem with WD5000BMVV:

Patient PCB was USB: 2060 701675 002
Donor PCB was SATA: 2060 771672 001

Patient was spinning with original USB PCB. I moved U12 to donor SATA PCB and drive does not even spin up.

The process of moving U12 was 100% correct, so the problem was not in the soldering job.

No doubt about your soldering skills.

I have the same case like yours before with the same drive and same PCB numbers, but it worked for me and I could access the SA and fix the damaged modules. This is weird.

Is it possible that U12 on the USB board is configured to Power Up In Standby (PUIS), and that the bridge firmware in U14 is what wakes it up?

The PUIS flag is stored in MOD 0D in the ROM.

Otherwise, could it be that the drive needs to see a SATA controller before it spins up?

AIUI, the 2060 and 7060 numbers reflect the PCB artwork whereas the 2061 and 7061 numbers reflect the loaded components. Is it possible that two apparently identical PCBs actually have small differences in the componentry?

For example, I know that there are optional programming resistors that configure the behaviour and functionality of the MCU on certain PCBs.

Would it be worth isolating the preamp connections for test purposes?

Fact : Just fixed one -few minutes before- with PCB # : 2060-701675-004 REV P1 ( USB interface ) with donor PCB # : 2060-771672-004 REV A ( SATA interface )

the drive had some damaged modules so I replaced the PCBs and worked on SATA interface after swapping U12 only ( theres no place for U14 on the SATA PCB ) then after fixing the drive back the USB PCB, and the drive now is working like a charm.

That is what's supposed to happen in theory. Nice.
