FRAGILE. When removing components from a 45xx module, be sure to place them in an area
where they cannot be stepped on or otherwise damaged.
To protect a disk from mechanical damage, handle the disk drive with great care when it is out
of the 45xx disk module. Do not let it drop, or subject it to sudden or jarring movements.
