Hard drive shorted electrically

My computer has been toast for a while after a few power surges that we had, and I figured that a capacitor had shorted in the power supply, I took it apart and found the fuse blown inside, I ordered a new power supply and installed it and it still won’t turn on. I found one of my hard drives had an internal short between 12+ and common. I traced it to a zener diode that is for protection of the drive that had shorted, a quick removal of the bad part and it’s all up and running again.
