Check out the linked video. Vibration during read operations just causes delayed access as the disk drive re-tries the read. That same vibration during a write can result in corrupt data on the disk.
Quite a few years ago I wanted to migrate data from some old tapes onto newer media. The tape drive, having sat unused for quite some time, had developed a flat spot on the pinch roller and vibrated quite a bit when running. It could read the tapes just fine, but I was getting huge numbers of error messages from the target disk drive that was mounted in the same housing. I had to remove the tape drive from the computer and set it on a foam rubber pad in order to complete the operation. (The tapes and drive were subsequently junked.)
