Sat at my desk one day happily carrying out my programming duties... All of a sudden a expletive, or more exactly a stream of profound and harsh expletives, come from behind my managers monitor. He stands up ashen faced and beads of sweat already forming on his brow. In updating the software for the main customer database for the company he had reversed the source and destination databases and totally blatted the whole thing. All of the information about sales and support and leads was gone. The most recent backup month older. Thankfully we had a development backup from earlier that morning.
Our main office is 50 miles away and this is in the days before decent internet connections and the backup is far too big for us to copy.
The two of us make an excuse about it seems to be some kind of hardware fault on the server take the system offline by deleting a random dll. We jump in the car like batman and robin - driving in a not dissimilar way to the office with a freshly burned CD with the data.
Later that afternoon we're fixed. Losing only a tiny amount of work that we put down to what could be a failing hard drive that we would "keep an eye on" looking like geniuses because in one day we not only fixed the hardware, updated the software, showed how willing we were to drop everying to support head office, etc.
