Re: Nah. We were civilized, no rodeo in the data center.
There were times when those large froppy dicks would seem to wobble because of the holes.
Extremely unlikely; froppy drives run at 300 or 360 RPM, and the mass of the actual disk is just a few grams.
Sometimes people managed to get the disk into the slot in such a way that the central hole didn't quite line up with the drive hub, and forcibly closing the door would put a nice dent in the side of the hole, or even cut a segment out of it. Usually that was the end of the disk, although I can imagine people reformatting, and reformatting again, and again and again, to save those precious froppies.
