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.
