Burnt seagate harddrive

[gstyle17007]

Used a higher Voltage and higher Amp power supply that the one that came with HDD.
Harddrive is a 3tb Hdd seagate.

The hardrive got warm and smelt like it was burning.

It seems as though a part on the pcb is burnt.

Am I correct in thinking I need a new pcb and then to move a chip from this pcb onto the new
one?

And how exact does the new pcb board have to be cause it is a 3tb harddrive that I did it on.

Meaning could I use a 1tb pcb with it ?

I had it connected though a caddy when I tried it.


Thanks.

What did you do exactly?

Most devices have some form of voltage regulator to protect the device from over voltage.

The power supply that came with it was

12V 1.5A 18VA

And the one I used was

24V 1.75A

Are the two black diodes at the right for the purpose of protecting the pcb if you put in more or less voltage than what you should?

They're not really in the right position to be used to regulate input voltage. They may be used for the brushless spindle motor. Given that the drive uses a SATA power connector I would expect an input voltage regulator to be a part of the enclosure. A cheap enclosure may omit this basic protection to cut costs.

As for repairing it, you should probably fire off an email to Seagate's support team. Their technicians will be best equipped to advise you on what needs to be done to repair the hard disk.

EDIT: I was looking at the drive in the wrong orientation, those diodes could indeed be for supply voltage regulation

Is there a way to check with a multimeter if they are for the supply voltage regulation.

Have tried plugging the drive into computer and it didn't work.

But when i used the high voltage power supply it was when the harddrive was in the caddy.
