Psst! Anyone seen that missing hard drive?

The National Archives is offering a $50,000 reward for recovery of a missing computer drive containing sensitive Clinton administration data.

The Western Digital My Book external hard drive was discovered missing about March 24 from an Archives processing room in College Park, Md. The Archives said Friday that its inspector general and the Secret Service have not uncovered any evidence of theft or targeting of the device for its data.

The drive can hold enough data to fill millions of books. It contains backup tapes from the Executive Office of the President, including some Social Security numbers, addresses and Secret Service and White House operating procedures.

Those with information are asked to call the Secret Service at 202-406-8800.
