Disk Sanitization Best Practices

  • Clear: Applies logical techniques to sanitize data in all user-addressable storage locations for protection against simple noninvasive data recovery techniques; it is typically applied through the standard read and write commands to the storage device, such as by rewriting with a new value or using a menu option to reset the device to the factory state (where rewriting is not supported).
  • Destroy: Renders target data recovery (using state-of-the-art laboratory techniques) infeasible and results in the subsequent inability to use the media for storage of data.
  • Security level of the data stored on the device
  • Whether the device will remain under or leave the organizational control
