Some laptops, Toughbooks and Thinkpads come to mind, mounted drive on foam pads or in rubber gaskets. A lot of MFM era drives up to mid eighties used to suspend mechanical part on rubber isolated posts.
Thinkpads also introduced accelerometers to park the heads when a laptop leaves a desk before it can hit the ground. Seems like at some point they decided the extra square millimeters were more useful for something else, like making the laptop a half a mm thinner.
