Preventing Damage to Drives

To prevent static damage to drives, follow these precautions:

Handle drives gently, using static-guarding techniques.

Store drives in the hard drive carrying case. Do not use the MultiBay device carrying case.

Avoid dropping drives from any height onto any surface.

Handle drives on surfaces that have at least one inch of shock-proof foam.

Avoid touching the connectors on the hard drive.

Grounding Methods

The method for grounding must include either a wrist strap or a foot strap at a grounded workstation. When seated, wear a wrist strap connected to a grounded system. When standing, use footstraps and a grounded floor mat.
