hdparm --security-erase NULL /dev/sdx

The above Linux command tells the disk to wipe all of the data on the drive irrecoverably.

Googling, I find a few examples of people saying that ATASE has been implemented incorrectly in the past. However, has anyone ever actually rescued data from a drive where the ATASE process was completed and reported success?

I'm talking about a good ole electromechanical, magnetic HDD, not a solid state or hybrid drive. parently someone managed it on an SSD in 2011.

  • Does a hybrid drive counts as HDD? I don't have any actual example, but I think they'd be vulnerable to the same issue as SSD, or worse if the manufacturer don't wipe the flash cache during ATASE. – Lie Ryan Apr 8 '17 at 2:11
  • Yes, but only because of a bug in the firmware which lead to the drive reporting success without actually wiping anything. I don't believe there has ever been a case where an actual overwrite has been recoverable. – forest Nov 13 '18 at 4:29
