Alright, so here goes. I have a housing for a HDD that I stuck a Seagate Barracuda 7200.10 320gb drive in. I use it for storage for my Xbox 360. One day it wouldn't work. So I messed with it and noticed that the drive wasn't spinning up. So I looked at the hard drive and notice that there is something on the PCB that is burnt. It kinda looks like a diode or something like that to me. I will attach a picture so y'all can see what I mean. But how do I fix it? Replace the PCB or the diode or whatever it is?
