Bad capacitors do not cause destructive voltages. If you knew otherwise, then you posted specifications and numbers to say so. You don't for one good reason. That damage is not possible. And spec numbers contradict those denials.

ATX specifications define protection ... with numbers ... that say why a PSU (properly designed) will not harm drives. If you know otherwise, then define the disk drive part put at risk. And provide numbers from datasheets that define why that part is damaged. Good luck.

PSUs contains circuits to prevent electronics damage long before the IBM PC even existed. Long an industry standard.
