SEDs securely erase their internal encryption keys, effectively destroying all of the data present on the drive. For Non–SED drives, the erase operation consists of a series of write operations to a drive that overwrites every user-accessible sector of the drive with specified patterns. It can be repeated in multiple passes using different data patterns for enhanced security. The sanitization technique is more secure than a simple format operation and is commonly called a “clearing” operation, similar to the existing physical drive clear command.
Follow these steps to set physical drive properties.
