Seagate Model: ST380013AS - PCB Chip Burn and Smoke

[jag17]

Hi

I have a seagate 80GB SATA 3.5" Disk

Model: ST380013AS
S/N: 5MR17WZB
P/N: 9W2812-231
DATE CODE: 05383

The user connected hard disk to an external usb casing to transfer data, but as soon as the external casing was power on, smoke came from the hard disk PCB and the whole room power tripped.

Please find the attached picture the red circle chip located near the SATA connector is giving out smoke when powered on.

What chip is the name of the chip?

Is it possible to replace chip from another similar hard disk and recover data?

Thanks for your help

Cheers

it's diode. just remove it if it short.

I believe that's the 5V TVS diode. If you can trust your power supply, you can remove it and run without it, or you can replace it with an SMAJ5.0A.

Here is one possible substitute (Farnell has others):

Just to be sure, confirm that the diode's pins connect to the +5V and ground pins in the SATA connector:

Thanks for all your input

I have a similar hard disk, so I will take the diode from working hard disk and solder on to bad hard disk and try to recover
