Releasing inert gas from fire suppression units that were over pressurized resulted in an extremely loud noise – 
causing cabinets 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.
