'I just bought your hard drive'

One year ago, Hank Gerbus had his hard drive replaced at a Best Buy store in Cincinnati. Six months ago, he received one of the most disturbing phone calls of his life.

"Mr. Gerbus," Gerbus recalls a stranger named Ed telling him. "I just bought your hard drive in Chicago."

Gerbus, a 77-year-old retiree, was alarmed. He knew the old hard drive was loaded with his personal information -- his Social Security number, account numbers and details of his retirement investments. But that's not all. The computer also included data on his wife, Roma, and their children and grandchildren, including some of their Social Security numbers.
