While investigating a major meth laboratory, Charlie and Megan recover a hard drive belonging to the primary meth distributor. Unfortunately, the disk had been badly damaged by the explosion of the meth lab. In spite of that - and luckily for the investigators - in many cases it is still possible to recover data on a badly damaged drive by making use of a computer's built-in redundancy in data. Essentially, even large portions of the files on a drive are lost or erased, because of symmetry and redundancy in most modern data storage, Charlie had a chance!
The President is scheduled to announce the landing of the Galileo V on Mars and broadcast some images from it. A writer from NASA's public affairs department wrote the announcement, but the President finds issues with it, most notably some redundant words and unnecessary adjectives (ex: "extremely unique"). The President tasks his writer to redo the announcement, and he states the rewrite eloquently.
