I remember in college we were going back and forth between our dormitory and our computer lab with a bunch of FDs to copy the media files (mp3s and jpegs) we downloaded on the server overnight. Often one of the disk would have errors and had go back another time.
A few years back, at $work we found some old FDs with some interesting labels on them: "survey data 199x". It turns out there were some binary files from an ancient stats program and I spent a few days figuring out how to extract the data. Fun times
