You can destroy data stored on disks using Storage Encryption for security reasons, including sanitizing the disks, setting the disk state to end-of-life, and emergency shredding of the data.
Sanitizing disks using Storage Encryption before return to vendor
If you want to return a disk to a vendor but do not want anyone to access sensitive data on the disk, you can sanitize it first by using the disk encrypt sanitize command. This renders the data on the disk inaccessible, but the disk can be reused. This command only works on spare disks.
