Yes.

Good.

Help the mass market more accurately measure how often the millions of
commodity HDD's actually do fail to read back what was written, and
you'll get noticed, I think.

We can't know til after we run this experiment?

We might actually discover that in fact quantifying the real experience
of HDD failure does gives us numbers roughly equal to the more easily
repeated, carefully controlled, therefore useless to me, laboratory
results that some folk prefer to publish.
