Well heck, no one who cares about his data would do that... You
replace the drive, let it rebuild, and *then* do the update.
Or... don't buy sucky h/w in the first place. If you *really* care
about your data, you spend the extra bucks for quality h/w that has
a competent support staff behind it. And you pay for an adequate
backup solution!
Otherwise, "you" are blaming on the h/w the sins of the humans who
bought the crummy h/w.
