Submission + - The Great Zero Challenge

An anonymous reader writes: The Great Zero Challenge — "It is noble and just to dispel myths, falsehoods and untruths." A challenge to confirm whether or not a professional data recovery firm or any individual(s) or organization(s) can recover data from a hard drive that has been overwritten with zeros once. We used the 32 year-old Unix dd command using /dev/zero as input to overwrite the drive. Three data recover companies were contacted. All three are listed on this page. Two companies declined to review the drive immediately upon hearing the phrase 'dd', the third declined to review the drive after we spoke to second level phone support and they asked if the dd command had actually completed (good question).
