Certificate for Destruction

The NIST Guidelines for Media Sanitization, NIST Special Publication 800-88, discussed in the Tip of the Night for August 9, 2020, includes a Certificate of Sanitization that you can use to verify that data has been completely removed from a storage device.

This is a good official record that can be retained after a device is processed, that will note how data was purged, and whether or not the device was re-used.
