hi there, just wondering if this component is replaceable? the drive went pop with smoke and this is the only part i can find at fault.
If i were able to get on, and If i were able to solder it on could the drive work again?

what is the part called and where can they be bought from?
below is a picture of the part i need, it has WE 66 A on it.

thanks for any help.

Its called a TVS.
Do some search about TVS on this forum and you'll quickly understand how to solve (if nothing else is damaged).

On the other hand, Q3 legs seems unsoldered and what the hell happened with the power connector?

The WE marking code is used by Vishay / General Semiconductor for a bidirectional 5V TVS diode, p/n SMAJ5.0CA.

Normally these diodes are unidirectional.

Even more confusing, the same marking is used by Vishay / General Semiconductor for an SMZG(J)3791A 12V zener diode.

If you can upload a photo of the whole corner of the PCB, I believe that will confirm that it is a 5V diode.

I am starting to feel that the bad diode is the least of your problems...
