Yeah.  I've seen hardware failures triggered by big system updates
before now.  It's not particularly common, but it is possible for the
amount of IO churn involved in updating to tip a marginal component over
the edge.  Generally you'll only see this sort of effect if the system
is otherwise pretty quiet during normal operation.

As to the failure mode -- sure these things usually die completely, but
they can die gradually and in subtle ways, usually when doing that is
the most inconvenient possible thing.
