Seagate drive burnt component.

[asvybre]

Hello guys!

New to the forum but I have a hard question that I didn't find the answer to everywhere.

I have got a seagate mobile hdd 1 TB (st1000lm035) and somehow this small component (image) in the pcb burned, I don't want to spend any more money on this and if I managed to find the component number and order it, maybe replacing it (I can solder) would let me remove the files from the drive before trashing it.

Thank you very much for the help!

It looks like a 5V TVS diode, in which case the drive should work without it. Just make sure that the correct voltages appear at the SATA power connector.

Thank you fzabkar, for all the interesting info!

I actually just tested it and it is surely working after I removed the burned component. I have on more question tho, the hdd was being used on a mac and apparently this mac shut down after awhile from overloading maybe. If I fix it, it will probably happen again, right?

I'm thinking this is not suitable for the mac since it was being used with a type c cable and it came with usb3.

But thank you again!

A shorted TVS diode points to an external overvoltage event, so your power supply must be the culprit.
