  • Publication number: 20220059130
    Abstract: A system and method for first changing the encryption key on a self-encrypting disk drive followed by a complete disk wipe. Either process can be separately performed, and they can be performed in any order. In fact, one embodiment of the invention, resets the symmetric key, wipes the disk a predetermined number of times with different predetermined data patterns, and then resets the key a second time. This assures that there is absolutely no way to recover the original key or to read the original plain text data, even if some of it's encrypted values remain on unallocated tracks after wiping. A user can be assured that in milliseconds after starting the wiping process, the entire disk is rendered unreadable and unrecoverable. Verifiable data can be pre-written to a device that is later read back to assure that wiping or firmware-based erase commands have worked.

  • Patent number: 10445534
    Abstract: A storage device wiping system and method that is activated from a remote server or other site when a computer is reported lost or stolen. The wipe technique selectively wipes all data files and free space before beginning to wipe the entire storage device. This causes any personal data files, photos, videos, and the like to be wiped first. Once the wiping process starts, it will continue until complete. The process starts or continues whenever the computer is booted. Only when all personal and sensitive data is wiped, will the system then change the encryption key (if there is one) and begin wiping the entire storage device.
