Data recovery and disk repair questions and discussions related to old-fashioned SATA, SAS, SCSI, IDE, MFM hard drives - any type of storage device that has moving parts

Hi,
My WD10EADS crashed and now I got a similar model with even the same number for the PBC (Printed on PCB, no label).
I did not change the chip with the rom on it, just replaced the PCB.
When I now connect the HDD with the PC, the HDD still doesn't start to run. The bios knows something is plugged in, but can't get the information, so it leaves the info for Sata blank.
Cause for the HDD crash was probably an over Voltage - the smooth chip burned.
Could the motor be broken, too?
Do you have any experience with such behaviors?
Regards,
Peter

Hi,
Is it making some soft chirping sounds, or nothing at all ?

HI
only professional can solve this problem search someone Pro. belongs to u r place in this forum

And is the donor-pcb still working on the original drive ?
There is a chance this one will be defective also now.
I must agree with microsoftengineer that this is a job for a pro. Even for us these drives are difficult ones to work with.

I got a new HDD with that PCB. The new one works just fine.
When I replace it, nothing happens with the damaged one.
I get the PCB back to the new one, works again.
Seems like the damaged HDD is entirely dead?
But I don't see anything damaged, other than the burned smooth chip of the PCB.

Ah, there you say it; burned smooth.
This can cause several thing, from bad to very bad.
Could be head stiction, could be motor dead and could be preamp blown/heads dead or any combination of this.
Sorry to say, but if data is important, send it to a pro.

After you installed the replacement PCB, did you hear or feel any attempt by the drive to spin up?
Can you measure the resistances of the motor terminals? Use a multimeter on the 200 ohms range.

I vote for preamp.

It seems there could be a ROM difference. All Adaptives, Heads map and some other Micro Code is on the PCBA. So switching PCBA's on WDC drives is hit and miss.
If the data is important to you, send it to a professional.

Smooth chip can damage preamp in the HDD. Plus adaptive data is a second factor in this one. Can be that the board is not compatable and without proper tools to work on this drive and the head alignment problem. You have done about all you can by yourself. If you send the two drives to a DR company in your area or find someone here not too far away this could be better in your recovery efforts on this one. Now it is beyond DYI repair and you need somene who has the tools and knowledge to help you in this one. Sorry but once this does not work then there is not a lot more you can do alone. Even if you have solidering skills and can move the adaptive data stored on the Marvel chip this one is not easy to do. Might want to consider some help in this one. It is your choice on this.

Thanks guys for all your replies and opinions.
At the moment I am fighting with a try. Most likely you wouldn't recommend that at all, but
how high is the chance of a successful transfer of the data disc's inside the HDD from the broken model
to the 99% equal working model. Creating a dust free workplace and open the HDD's.
If you have a percentage in mind, or from experience, I would be happy to hear. The worst case would be getting both
broken and so waste the warranty and the value of the working one.

About the precentage it's less to zero or worse.
Trust me. And good luck also.

If it makes you happier, then I say 100%, if you have nothing to loose.
Or 1000, or 100000000000 % (doesn't change anything).

BlackST...you forgot about me? I'm waiting for your help.....
June 20th, 2010, 19:40
lol this is 99% the same as my problem
wd10eals-blown-pcb-t15999.htmlim getting another drive later this week and will attempt to change the rom chip like in this video
http://www.youtube.com/watch?v=X2hgiDHiXKMwill update you if it works
tried it on some old dead drives and it was pretty simple all you need is a heat/hot air gun and some tweezers

@Mega 2k
did it work?
I have also a broken WD2000JD - 00GBB0
After several weeks now of looking for one on ebay, I must find out that the 00GBB0 is a very rare model.
There is the question if one of the 00HBB0 will also work for PCB replacement.
Do you guys have experience with that?

with no Experience maybe 0.5%

WIth a 80gig WD the percentage will be well below 50% if more than one platter. I have had lots of luck when I swapped the head stack in a 80gb WD with one platter, so head alignment is not such a big deal as it is for more heads. With the density of a Terabyte drive, I would guess the percentage will be very, very low. Your problem sounds like a blown head amp, so swapping the head stack would do the job - no reason to play with platter-platter alignment.
