In all this cases the people knows that needs an architect, an aeronautic engineer and automobile engineer, respectively. But who has the guilty of this way of think?

We can classify the ways that hard disk can breakdown in two: software and hardware. With the first I'm talking about the lost of data due to virus or accidental erasure. In these cases, if it's possible retrieve the information, it is often so cheap because only we have to use the appropriate software. Instead, the errors of hardware or physics are very expensive of repair, because are needed tools and specialized installations and only if the information that contains is enough valuable, can worth pay for it.

Signal warning of radiactivity
The processors aren't inmune to the radiactivity. This it produces soft errors, that are errors in the signals of its circuits, produced by the noise that generates the radiation on it. The consequences of the radiation over the machines aren't so devastating as over the human, because in the worst case we can reboot the machine, but the things that could do the machines affected by radiation to the humans, it could be dangerous. Enter into "The machines neither are inmune to the radiactivity"
