CWmike writes "An external hard drive that's believed to contain nearly 1TB of data from the Clinton Administration is missing from the US National Archives and Recording Administration (NARA). The drive includes more than 100,000 Social Security numbers and home addresses of people who visited or worked at the White House. Among those whose information is on the list is one of then-Vice President Al Gore's three daughters. The drive also contained details on the security procedures used by the Secret Service at the White House, as well as event logs, social gathering logs, political records and other information from the Clinton administration. Rep. Darrell Issa, (R-Calif.) said the Archives was in the process of converting information from the drive to a digital records system when it apparently disappeared. The hard drive was apparently removed from a secure storage area to a workplace where at least 100 'badge-holders' had access to it, Issa noted."
