The SECURITY ERASE UNIT command feature is enabled by issuing the SECURITY ERASE PREPARE command and then the SECURITY ERASE UNIT command. The SECURITY ERASE PREPARE command prevents data from being erased unnecessarily by the SECURITY ERASE UNIT command.
Issuing this command during FROZEN MODE returns the Aborted Command error.
