5.3 Host Commands
Although this command invalidates the user password, the master password is retained. To recover the master password, issue the SECURITY SET PASSWORD command and reset the user password.
If the SECURITY ERASE PREPARE command is not issued immediately before this command is issued, the Aborted Command error is returned.
Issuing this command while in FROZEN MODE returns the Aborted Command error.
