So far I always assumed that, when talking about HDDs failing rates, they where considering the typical mechanical failure. I never considered that they could declare a failure due to some corrupted data, although it would be reasonable for a datacenter to do so.

Mechanical failures were more prevalent in my experience in 90s, most of the recent stuff is usually see are controller failures. I rarely hear any head crash clicking like the old days
