Diode Identification or equivalent

Hey can anyone tell me what kind of diode these are or the equivalents I can use? They are the two shown in the picture that are fried. One has markings "3404" and the other says "BUX C039"

Thanks

Hey don't worry about it now I soldered some unidentified diodes in the place of the old ones and it works. BTW it was the pcb from a hard drive that died in a tragic power supply accident. LOL
