head replacement

August 18th, 2014, 6:38

Hi everyone.

I made a head replacement on a western digital hard drive. apparently the heads are ok. i cheked the pcb and it is ok. but i still do not get to the data. the donnor I used obeys to the rules of head replacement for WD HDD. My question is why it continues not functioning?

My guess is that you misdiagnosed your drive and made your problem worse. I suggest you put everything back together in the original state and send it to a pro and cross your fingers that it is still recoverable. Not even knowing what the original symptoms are, the model of drive, what equipment and experience you have, I cannot speculate on how much it would have cost before you started working on it, but I suspect that it will likely be at least double that price now.

Contact your preferred data recovery lab as soon as you encounter the issue.

What are the symptoms of the drive? What happened?
Why did you changed heads? Where did you based yourself to know what/how to change?

Hello there Tiago Costa,

As Icoughey already mentioned, by opening the drive, you may have had further damaged the drive and the stored data on it.
We can not be really sure what the exact problem of the hard drive is. So, if the data is important, I would suggest you to contact a data recovery company.

Regarding what type of diagnostic to use in future, I would say you should first try testing the hard drive with brand specific software. The Western Digital one is the WD Data Lifeguard Diagnostic tool.

I'm a eletronic engineer, and i'm doing a trainee on recovering data by 3 months now, first thing i have done was to put it on datacompass and I realise the noise that it made, and i couldn't get the data, so I oppened the disk and I could see the heads crashed so I surched for a donnor thta obeys the rules of head replacement and i changed the heads, Put it back to dta compass there isn't any noise on the HDD but i still can´t get the data.

If this is a client drive, which I hope is not, and Data Compass is your only tool, you really need to send to member, PCLab, and see if they can bail you out of this mess before it is too late.
