How do repair a computers hard drive?

It all depends on what the fault is. It is possible to swap the platter into an identical hard drive, or swap a faulty circuit board. Opening the sealed cover will allow dust in, unless done in a clean room.
Although a repaired drive may work, it's life will be shortened by the contamination.
