Caution To prevent damage from static electricity, follow
standard ESD procedures and avoid touching
exposed circuitry.
Do not remove a disk or filler from an operating product until
you have the replacement part and are ready to install it. An empty slot will
cause uneven cooling and eventual overheating.

Wait for a spinning disk to slow down and cool off
before removing it from the product.

drive electronics when removing and inserting disks.
