If an Encryption solid-state drive or a Disk Encryption hard disk drive or a Disk Encryption hybrid drive is
supported and installed in your computer, you can logically dispose of all the data on the drive in a short
time by erasing the cryptographic key. The data encrypted with the old key is not physically erased but
remains on the drive; however, it cannot be decrypted without the old key. This feature is also available with
the Drive Erase Utility for Resetting the Cryptographic Key and Erasing the Solid State Drive tool.
