Environmental protection
Seagate designs its products to meet environmental protection requirements worldwide, including regulations restricting
certain chemical substances.
certain chemical substances.
2.12.1
European Union Restriction of Hazardous Substances (RoHS) Directive
The European Union Restriction of Hazardous Substances (RoHS) Directive, restricts the presence of chemical sub-
stances, including Lead, Cadmium, Mercury, Hexavalent Chromium, PBB and PBDE, in electronic products, effective July
2006. This drive is manufactured with components and materials that comply with the RoHS Directive.

Corrosive environment
Seagate electronic drive components pass accelerated corrosion testing equivalent to 10 years exposure to light indus-
trial environments containing sulfurous gases, chlorine and nitric oxide, classes G and H per ASTM B845. However, this
accelerated testing cannot duplicate every potential application environment. Users should use caution exposing any
electronic components to uncontrolled chemical pollutants and corrosive chemicals as electronic drive component reliabil-
ity can be affected by the installation environment. The silver, copper, nickel and gold films used in Seagate products are
especially sensitive to the presence of sulfide, chloride, and nitrate contaminants. Sulfur is found to be the most damag-
ing. In addition, electronic components should never be exposed to condensing water on the surface of the printed circuit
board assembly (PCBA) or exposed to an ambient relative humidity greater than 95%. Materials used in cabinet fabrica-
tion, such as vulcanized rubber, that can outgas corrosive compounds should be minimized or eliminated. The useful life
of any electronic equipment may be extended by replacing materials near circuitry with sulfide-free alternatives.
