Computerworld: ‘Google is shedding some of the secrecy around its data center practices, with a new video that shows extensive security measures and the destruction of old hard drives to prevent leakage of customer data. Google “rigorously tracks the location and status” of each hard drive, destroying failed hard drives with a multistep process before gathering the mangled bits in boxes to send off to recycling centers. “One device that is used to destroy old hard drives is known as the crusher,” the narrator of a Google video says. “A steel piston is pushed through the center of the drive and the platters are deformed, making them unreadable.”
