Thanks for the smartmontools and good points.

The "will get very hot in the process" is part of the test! Something
that badblocks doesn't really exercise. Hence the question...

Thinking further, is there something like Bonnie but that also verifies
the results rather than merely gathering timings?...

Or do people just assume blindly that their disk drives just simply
work, flawlessly?

(Or am I the only one to have had new HDDs "doa" or soon-to-die?)
