So, you think those embarrassing emails sent to the computer's trash can are truly deleted, right? Uh, no:
"The House Committee on Oversight and Government Reform is investigating whether the White House or the Republican National Committee erased 'a large volume of e-mails' that may be related to the firings of eight U.S. attorneys.
"Deleting a document or e-mail doesn't remove the file from a computer's hard drive or a backup server. The only thing that's erased is the address - known as a 'pointer' - indicating where the file is stored.
"It's like 'removing an index card in a library,' said Robert Guinaugh, a senior partner at CyberControls LLC, a data forensic-support company in Barrington, Ill. 'You take the card out, but the book is still on the shelf.'"
