Seagate ST2000DM001 with overvoltage problem

[jazzme]

Hello to everyone,

I have a problem with a Seagate drive that I desire to solve, and I need advice about it. I need to get out my data


HDD specifications:

Model: ST2000DM001
PN 1CH164-572
FW: CC44
Date: 13165
Site: Tk
PCB: 100687658 REV C
1332F

It was in a external case, and i had a power wire confussion, and i conected it to the laptop 19V wire, instead of its own 12V wire. Aparently nothing happened. But the PC didn't dettect de external HDD. And then i saw that the hard drive wasn't spinning, only the blue led was blinking. I disconnected the power wire, and when i conected the worrect power wire the HDD didnt work either. Then i extracted the disc of the case. I tried to conect it to the pc with a SATA-USB adapter. And of course, it didn't work, and i saw some smoke under the PCB.

I extracted the PCB and i saw the next:
(link whith this and other HD pics at the end of the post)



And here is the smoke source. ¿Is it the only problem?


I don't see any other damaged component. But i am not a expert.

I have read a lot of things:

1.- Remove the burnt piece and short-circuited. Is it a diode? it could solve the problem?. Perhaps, the PCB, can have more damaged components, and the problem may be bigger.

2.- I think it's a Seagate F3 PCB, and i can't change the pcb for other identical one. (it's true?). Then:

3.- The third and last option that i have read is to get a similar pcb and transfer the old ROM (eight contacts component) to the new pcb and add the new pcb to the HDD, and try to conect back to the pc.

On this case, can this pcb be valid? http://goo.gl/1QvprT
Perhaps you know another cheaper one?




What do you think about it?
What can i do?
What can be the option?
What % of success I have?


Thanks for everything. I appreciate the help. I'm not sure how to fix this.

Remove the damaged component (TVS ) nothing more, not short-circuited.

Hdd should return to work, but keep in mind that would not be protected against new Overvoltage, make sure the power supply is correct.

There should be more damage.

Check the 12V TVS diode (it will be shorted) and the 12V zero-ohm resistors.

If i extract the damaged component.... ¿The pcb must to work again?. Without it¿?. Then the circuit wil be open, isn't it?

Check the 12V TVS diode (it will be shorted) and the 12V zero-ohm resistors.

fzabkar...,

i would like to know about yo are telling me, but the links doesn't work to me


Thank you very much for your help. I hope can solve it in easy way

Sorry to revive an old thread. I have a similar issue.

If the 12V TVS is blown, do I need to solder over and connect up both the 12V zero-ohm resistors?

[mr_spokk]

No, just remove...and if you have a new one..put it back

[Taserx]

Ok thanks

If the zero-ohm resistors measure open circuit, yes, they need to be replaced.

Hi...i will suggest to Post a clear closeup pic of the component side of the pcb. The TVS diodes will be two small black rectangular components with one solder pad point on each end in the area right behind the power connector. PCB swaps on this family often require relocating or reprogramming the ROM chip due to information stored on the board that is particvular to that specific drive. The information from another drive usually is not compatible.
