Interface
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.
