All of this skills the point. This is a second drive that failed, it was the replacement for an earlier drive that failed.
That’s what the article is all about.
A high, unexpected and unreasonable failure rate.
I had a high failure rate in some Seagate drives in the early 00s. Switch vendors and never had the problem again.
We also do no know how they failed. Are they still image readable with ddrescue or spinrite for example or are they truly crashed. It is not clear if they even tried.
