Modern disks still have a filtration system and airflow within the disk.
Air usually gets sucked from the edge then through the spindle and out
the center. In this case I think the spinning created a lower pressure
area where the heads were, resulting in the heads flying too low.

Does anyone have or know whether the schematics for the IBM 5110 or 5100 are
available?
And the tightly related question of whether anyone has done ROM (ROS) dumps?
There are some service manuals on bitsavers, they are field-service board-level
