Western Digital Corporation (often abbreviated to WD) is the second largest computer hard disk drives manufacturer in the world, after Seagate and has a long history in the electronics industry as an integrated circuit maker and a storage products company. Western Digital was founded on April 23, 1970 by Alvin B. Phillips, a Motorola employee, as General Digital, initially (and briefly) a manufacturer of MOS semiconductor test equipment. It rapidly became a speciality semiconductor maker, with start-up capital provided by several individual investors and industrial giant Emerson Electric Company. Around July 1971 it adopted its current name, moved to Lake Forest, California, and soon introduced its first product, the WD1402A UART.
