A portable, external hard drive lost by Health Net, which contained customers' personal information, was not encoded and could be read by commercially available software, Connecticut Attorney General Richard Blumenthal said. The hard drive was apparently stolen in May from Health Net's Northeast headquarters, rather than simply misplaced, Blumenthal said. But Health Net officials said it's still not clear whether the information was stolen or misplaced. The drive contained the medical claims and financial information of as many as 1.5 million customers in the Northeast dating to 2002.
