WD complies with the Restriction of Hazardous Substances (RoHS) Directive 2002/95/EC
of the European Parliament, which is effective in the EU beginning July 1, 2006. RoHS aims to
protect human health and the environment by restricting the use of certain hazardous
substances in new equipment, and consists of restrictions on lead, mercury, cadmium, and
other substances.
The reliability, performance, and specifications of WD products are unchanged from
previously manufactured WD products, remaining among the highest in the industry.
