seagate ST3120026A 120G burnt PCB

September 2nd, 2009, 15:46

hello all, i'm new to this board and i must say it is a very informative forum.
I've got a problem i'm hoping someone can help me with.
I've got the above mentioned hard drive and recently my power supply blew taking a few things with it, including this drive. Upon closer inspection, I noticed what I believed to be a diode exploded on the PCB. I was told that upon removing it that it would continue to function, but it doesn't. So, i've included a picture of it and am hoping that someone here can identify what the component once was so I can maybe replace it and get all of my data back! Please and thank you.

Hi, welcome to the forum. From your statements did someone in this forum tell you that it would work?
Also what did the one tell you that had made your pcb fry up? My next question is what do you wanna do to the hdd --repair/data recovery?

Someone told me that they had the same problem and they were certain that component could be removed and still ahve it work.
I'd like to repair the HDD and keep using it, but im mainly concerned with getting my data back.
So, either replacing that specific component or replacing the PCB.
What would the average cost be of professional data recovery?

It depends on WHO did tell YOU thatand if you know what youre doing :mrgreen:

Good luck.

What did your hard drive do before you removed that burnt item?

What is your hard drive doing now after you removed the burnt item?

Well, the component might have been something like FT403PV, maybe not, maybe similar.
Probably it matters not, because more than likely some other component/s is/are faulty. :wink:

So even if you find the match, as you have requested, your drive probably will not work.
So some other solution must be applied to get your data, which might require more than just DIY skills.

DR experts should be able to get your data quite easily, and if you mess around too much with the pcb,
you might just never get your data.

Maybe the drive already has a fault (electronic) on the circuits inside the hard drive (HDA) then of course
it's quite a big job, but more importantly, maybe something you do while "repairing" the pcb causes a fault
inside the drive (HDA), then you would be sorry not to have sent it to an expert in the first place.

Your call :D

Well, what I see is a BIG damage to the PCB (multilayer, btw). But data can still be recovered (hope there was no tinkering done on the HDA) because the problem - for me - is elsewhere , or better, IT WAS (now there are at least two).
The original idea was to do it by himself with no money and with the help of Internet (the realm of all knowledge and all bullshit at same time) and this is the result... Don't think data was important if such kind of attempts have been done, but I can be wrong....
I think only seeing the drive a cost can be estimated correctly.

For once I start to ask a novice ?'s and get the support of the pro's. Thanx guys for the assist and not telling him upfront to send it to a pro and all the crap (half truths) put towards a starter. Hey guys don't frighten him with too much know how. Talking big is not going to get his hdd working or data back. Please give him the steps on how to solve the issue.

For example.
1. if there was no clicking from the hdd then ....
2. Are u willing to send your hard drive to an expect for evalution who would....
3. Changing the PCB might .........
4 If changing the pcb does not .........
5. do you have any knowledge about how to write the firmware.....
6. Do you know how to image .........


Peace Out

hi felibo,
I wish I could understand what you are asking, suggesting, expecting, hoping, wishing, advising,
telling, complimenting, and what else? :?

arkadas,

This board is not suitable for Adasm.

Nice 1
:lol: :lol: :lol: :lol: :lol: :lol: ......................
You guys took the bait. wanted to see ur reaction by touching the hot buttons.
Blackst for instance has dicontinued his public service, folded his tent and left the pavilion
Derp is kind of confused for I tried to draw an outline for DR but there are so many ways for DR as there are in killing a cat.
Arkadas just supplied a hdd even though the pic adasm put up does not include any specs.
I was just hopping all the other guys pcimmage, jonants, falther, rameez, pepe, hdd spaz, thatdellguy, drccsc, hddguy... the pro's to name few could have joined to see the mess that would be created at the fair grounds.

SORRY, NO HARD FEELINGS
Peace Out

All I want is my data back.
I havent attempted anything to this board but to remove the remnants of said component.
The person who gave me the info was the tech guru at my company (an aerospace company).
I consider myself electronically savvy and can do alot of my own repairs, but i`ve never attempted anything on a HDD before, hence why i`m here asking questions.
I`m hoping to do this myself to save the hundreds associated with professional help.
I`m assuming if I replace this component it can work, or if not then replacing the PCB.
But again, i`m only assuming and came here to get answers. So, any more questions you may have about the HDD in question i`ll gladly answer, hoping that you can answer mine.
Additional info:

model: St3120026A
pn: 9w2083-301
HDA pn: 100278290

ok Adasm this is what u need to do AT YOUR OWN RISK
If u change the pcb you might have to get the firmware to match that hdd. So you might get the pcb but might need to write the firmware to the chip which needs special equipment that is why the saying is "SEND IT TO THE PRO'S"
So go ahead and find the pcb that matches the hdd, and if after changing it, and you power it on, and hear clicking noises don't say you where not forewarned. Then you would have to pay more to get the data you need.

Hope you can handle the truth

frelibo,

You just proven you know nothing about DR.

Adasm,

The way you hacked off the component in question shows that you cannot do the work
which is required.
You could start by going on a soldering course if you insist on doing this yourself. :wink:

get help bud, spend a little money and you will probably get your data.

Adasm sorry for giving u the wrong info. I thought I knew how to do DR but derp is the expert in that field. So I suggest u have to ignore my posting and PLEASE take his advice.

No hard feelings derp.
Keep the Peace
