Avoid exposing a hard drive to products that have magnetic fields, such as monitors or speakers. If a drive must be mailed, place the drive into a bubble pack mailer or other suitable form of protective packaging and label the package "Fragile: Handle With Care. " I I I I I I I I Maintenance and Service Guide 4­3 Removal and Replacement Preliminaries 4. 4 Preventing Electrostatic Damage Many electronic components are sensitive to electrostatic discharge (ESD). Networks built into many integrated circuits provide some protection, but in many cases the discharge contains enough power to alter device parameters or melt silicon junctions. A sudden discharge of static electricity from a finger or other conductor can destroy static-sensitive devices or microcircuitry. An electronic device exposed to electrostatic discharge may not be affected at all and can work perfectly throughout a normal cycle. The device may function normally for awhile, then degrade in the internal layers, reducing its life expectancy. 4. 5 Packaging and Transporting Precautions Use the following grounding precautions when packaging and transporting equipment: I I I I I To avoid hand contact, transport products in static-safe containers, such as tubes, bags, or boxes. Protect all electrostatic-sensitive parts and assemblies with conductive or approved containers or packaging. Keep electrostatic-sensitive parts in their containers until the parts arrive at static-free workstations. Place items on a grounded surface before removing items from their containers.
