An unidentified Chinese firm is attempting to buy Seagate Technology, one of the last two remaining disk drive manufacturers in the US, creating fresh concerns about the transfer of sensitive technology, the New York Times reported. Seagate CEO William Watkins said he told the Chinese firm that his company was not for sale while executives from Western Digital, the other disk drive maker, declined to comment. Speaking to the Times, Watkins claimed the move resurrected issues of "economic competitiveness and national security" that emerged when Lenovo bought IBM's PC division in 2005. Although disk drives do not appear on the official list of export-controlled technologies, several government officials said the deal would require a security review, as the latest hard disk drives come with built-in security and encryption software.
