8.22 Security Erase Unit (F4h)
This command requests transfer of a single sector of data from the host. Table 58 defines the content of this
sector of information. If the password does not match the password previously saved by the SSD, the SSD
rejects the command with command aborted. The Security Erase Prepare command shall be completed
immediately prior to the Security Erase Unit command. If the SSD receives a Security Erase Unit command
without an immediately prior Security Erase Prepare command, the SSD command aborts the Security Erase
Unit command.
