My experience is only with in-specification systems (and only in tape libraries) but those tests were pretty loud.

(I can't believe that I was allowed to conduct a test with them running, but I don't remember shutting them down.)
I wonder if orientation mattered--mine were all platters parallel to the floor, I wonder if the damaged ones were parallel to the wave front.
full of hard drives to vibrate – which got transmitted to the read – write heads of the drives. Amazing sort of outage + data loss, and this time the physical security plant chief gets to write up the RCA.
