> Non-SED Secure Erase Support

> This section describes the firmware changes required to securely erase data on non-SEDs (normal HDDs).

> 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.
