Hi,

WD My passpot 1 TB board : 2060 771961 001 revA. is not working.

Please checked here https://youtu.be/-DAEshpNcF0 to understand the issue and photo .

I am not sure what is the issue. please suggest next steps to recover data from this hard drive.

Regards,
Kishor

Oh dear, another DIY disaster

Just about worst thing you could have done is open the drive and run it in a non-clean environment without the lid on, which you have done.

It's NOT a PCB problem, well not now it isn't.

Not fixable with DIY and now you've almost certainly lessened any chances of pro recovery

New!! HDD-PCB.COM for all your PCB and donor HDD requirements!

If not PCB then what is the issue ? apart from non-clean environment...

Now, this is the problem.

Ok. thanks

Proper diagnosis always comes before surgery. You have performed the surgery without knowing the diagnosis. You have probably killed the patient, or at least significantly lessened the likelihood of recovery.

Thank you too...

I think people don't comprehend the gravity of how clean the internals need to be, and totally sidestep the issue that enginnering on the drives, that come down to 1,00's of a mm, are all based on the lid on. aerodynamics, airflow, etc.

I realized I did big mistake. any suggestion on what is next should I do ? I hope I should try something before I thought away this hard drive...

thanks...

I find it easy to understand, if something is hermetically sealed must be for a reason !

I agree, but I also understand ripping it open. I have pulled apart my car, stuff around the home many times to fix it. Hard Disks operation and manufacture is very unique in that unless you have already found out the hard way, or actually read the forums AND take the info in and believe it.. then you are going to be optimistic about either being able to fix it or get some insight to the issue.

How many times have you seen "no user serviceable parts inside" in a consumer appliance.. ripped it open and fixed a capacitor, broken wire or bad solder? many things on cars can be fixed with a cheap part from the auto store.

I Understand why people do it, but this is going to be a problem for ever.. imho

The other thing is people that haven't been exposed to this level of tolerance probably can't see how their actions can affect the, they might know they ned to be fairly clean, and careful with tweezers, but not HOW clean and HOW careful.

The human hair next to the fly height of the head has helped me explain it to some non-tch people.. though glazed over eyes is a common result

I have did a bit reading in various forums/videos and information from various topics, I thought it is head stuck issue and some suggestion was to open hard drive(in clean clean clean environment) and fix it... I did it my best to maintain clean environment. but, when I opened, head was not stuck...!!

before closing, I thought I should do video to get expert advice so I started hard drive with open case(I know I did biggest mistake... but, that is done part.. no matter how serious it...)

Still I am looking for...

If anyone could help on figuring out the issue. dead head/PCB/firmware etc... or if someone could suggest next steps to find it out the issue.

Proper diagnosis is the key, and you don't have the tools.

Most common recovery issues with this series are firmware or dirty heads from a head crash. There are some free or low-cost firmware tools that people talk about, but I have never tried them. Even if you had the tools, you would need knowledge of what to look for and how to fix an underlying problem. And now you have the additional need to decontaminate the drive.

Microscopes are very useful for examining heads for contamination. Yet some contamination is so fine that it is not readily apparent, even under magnification. But you must take care not to damage the head mechanically or from static discharge. If you see contamination, you can usually expect a read / write problem with the head.

If you value your data, send the drive to a pro. You will surely make things worse the more you try. There is a very long and steep learning curve to get any good at this, and the shortcuts are few and dangerous.

rightly said by jono-ats, even if you know the problem, chances of success are 0.0001%, sorry no offense. if data on drive is really very important seek professional help, send your disk a reputable data recovery company and get the estimate. later you can decide either you want to pay or proceed to full disaster by doing another wrong DIY technique.

Thank you jono-ats. your subject matter helps me to understand the risk and my chances.. may be I should avoid DIY.

background :

I was trying to connect two hard drive into my laptop with powered usb hub. but, it was not generating enough power to connect both hard drive at same time. so, this hard drive was getting started and stopped couple of times... then I changed the power cable of usb hub. I didn't realize that cable was with higher voltage and then this clicking sound started.

I suspect, I have given higher voltage to the hard drive...

Thanks MindMergepk.. now I understand the issue... thanks again.

Does it make sense to change PCB and check if this HDD works ?
One of my friend has the same hard drive as we bought those 2 HDD together...

This is a bad idea, you're just going to end up costing yourself a lot more in the end if you do end up sending it to a pro. The contamination from being opened without a cleanroom is almost surely quite bad on the top platter at least. Running heads over it any longer will only cause crashes. The drive needs to be inspected and any dirty surfaces cleaned, also heads replaced or cleaned depending if they look damaged already.

To change PCBs you would have to do a ROM chip swap from the donor PCB as they are probably different even if you bought them at the same time.

Thank you Green Slime. will have to visit a pro for this... I was just querulous to check my all options and reasons for not doing DIY.

That's understandable, always pays to research everything first. Just be very careful who you send it to. Make sure they actually know what they are doing and have a proper cleanroom. Anyone can say they are Pros but end up destroying your drive themselves and probably still charge you money.
