Obligatory reference to this TNG episode (one of my favorites) that deals with this very subject: http://en.wikipedia.org/wiki/The_Measure_of_a_Man_(Star_Trek:_The_Next_Generation)
In all seriousness I keep an 8" TANDY floppy disk in a drawer to amaze people with. The uninitiated tend to believe it's a novelty item.
I would mod this up if I could. Oil has saved the tracks off many a CD for me in the past. I recommend 3-in-1 small machine oil.
Quick! Someone back up all of the porn before we lose it all!
