2.15.1
European Union Restriction of Hazardous Substances (RoHS)
The European Union Restriction of Hazardous Substances (RoHS) Directive, restricts the presence of chemical 
substances, 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 Direc-
tive.
2.15.2
China Restriction of Hazardous Substances (RoHS) Directive
This product has an Environmental Protection Use Period (EPUP) of 20 years. The following table 
contains information mandated by China's "Marking Requirements for Control of Pollution Caused 
by Electronic Information Products" Standard.
"O" indicates the hazardous and toxic substance content of the part (at the homogenous material level) is lower 
than the threshold defined by the China RoHS MCV Standard.
"X" indicates the hazardous and toxic substance content of the part (at the homogenous material level) is over the 
threshold defined by the China RoHS MCV Standard.

Corrosive environment
Seagate electronic drive components pass accelerated corrosion testing equivalent to 10 years exposure to light 
industrial 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 reliability can be affected by the installation
 
environment. The silver, cop-
per, 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 damaging. 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 fabrication, such as vulcanized rubber, 
that can outgas corrosive compounds should be minimized or eliminated. The useful life of any electronic equip-
ment may be extended by replacing materials near circuitry with sulfide-free alternatives.
