Some computers might support a Disk Encryption hard disk drive or Encryption solid-state drive and have
such a drive installed. 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.

program.
