Something burned in this Seagate ST3160023AS HDD (160GB, 7200rpm) on account of the smoke and smell it produced.
After that the drive went dead without noticeable spin.
Examined it carefully and the only part apparently burned was the one indicated.
I suspect the problem was caused by trying to power it up by mistake with a 5V line instead of 12V.
Would be grateful if someone could tell me if the HDD can be repaired by replacing the part, and if so were can I obtain such part.

TIA

I have a duff board which that component is not burned on.

You can have it if you want, I'll unsolder this part and post to UK FOC.

Any help?

what does this part do and whats its name ? as i have many hdd with same problem .

thanks .

It's a choke coil or inductor. Used for either transient voltage control or to dampen or choke voltage in the circuit from other sources. Can also be used as an inductive load in a circuit with capacitors for buffering current. Since it seems to be in motor control area of PCB it may be used to help start stop spindle motor. I would check the motor IC and 8 leg IC beside it also if this component has burned.

Should add if you know for sure that the power connector was plugged in backwards you need to check pre-amp on heads & diodes near power connector. Even if you use a donor PCB if the pre-amp has died you will kill the new board as soon as you power it on.

Thanks, but I'm afraid that's a job far beyond my capabilities/knowledge.
Happily I have just discovered that the HDD is still under Seagate's 5 year warranty, so I am sending it for RMA.

You can purchase a donor PCB from ebay or similar for this component, but you may find it has burned out for a reason and may have other faults, much like what Shortcircuits has mentioned
