A small hard drive typically has only one platter, but each side of it has a magnetic coating. Bigger drives have a series of platters stacked on a central spindle, with a small gap in between them. The platters rotate at up to 10,000 revolutions per minute so the read-write heads can access any part of them.
Driving on under-inflated tires is very dangerous. If tires pressure is too low, too much of the tire's surface area touches the road, which increases friction. The more friction you have, the more heat is applied to the tires. Then, too much heat will make them overheat which can cause tread separation and, yes, blowouts. Therefore, the answer is true.
