Effect of Prolonged Vibration on Mechanical Hard Drive

I often travel by train with my laptop which has a mechanical hard drive.

I'm careful not to use the laptop during travel since there is a constant vibration that the drive experiences throughout. The magnitude is not much, but the vibration is prolonged (18 hours at a stretch).

Can prolonged vibration slowly kill the hard drive? Should I avoid taking my laptop when traveling by train? Or, if I do not use the computer and the head and the disk do not move during this period, is it safe?
