History: 2 HDDs same model. Dead after power surge at a time. 1 drive is fixed by swapping PCB only. 2nd drive has additional damage.

Hitachi HDD: HDS721050CLA382

Symptom: NO SPIN.

Findings: PCB Dead.

Action: Replacement with ROM.

Status: Still NO SPIN. But READY In HD Doctor. Load From HDD brings Error.

Next Suspect is FW. All modules corrupt/bad in SA-A & SA-B. SA-C has no access so far

Another task: It spins now for few seconds & SPIN DOWN again when it's connected without HDA contact. But Status is BUSY in this procedure, never READY.

So, what do you think? What would you do?

1) Killed headstack
2) Other problem not addressed in PCB.

Use DDA or similar to see what happens at HDA connector.

The behaviour of the PCB is similar in case of such failure (too few details).

Well, If it's the headstack - there are no CLICKING/TICKY etc...

What other problem are you referring that was not addressed?

By the way, I am not familiar with DDA (can you state please?)

What else do you need regarding PCB. (I ensure you the PATIENT PCB Is DEAD), & it's not the first scene like this case. I also noticed same problem in more 2 drives. 1 is 160GB and another one is 1TB (All the drives are CLA3 family)

Man, if you think you know it all, why ask here?

You seems didn't get my point. Ok, I rewrite: Patient PCB is dead as well as additional problem exist. But I can't catch the additional problem so far, that's why I am asking.

PCB is fixed by DONOR, but even after matching PCB, it doesn't spin, it only spins with DONOR when the PCB is connected without HDA contact. For few seconds only it spins and spin down. The same behavior I noticed into 3(three) CLA3 hdds so far. Did you face the problem earlier on these CLA3 HDDs?

Do you think it's NVRAM failure as well?

If you upload a detailed photo of the PCB, I could help you locate the supply and signal pins for the preamp. We could then compare your two drives.

Shahij, instead of wasting your time with another analysis, in absence of DDA, why not replace heads with working pcb? 20 minutes and if everything is ok you should be done (if you don't have other problems around of couse).

NO Clean Room service here. Need to outsource abroad if headstack is the scene.

I think the original problem was PUIS enabled on the drive!

Those are two different boards. I need a detailed photo. A quick analysis will take only 1 minute and will tell you whether you really do have a preamp problem.
