WD MyBook Essentials - Can't use after swapping drive

I understand that this configuration is not officially supported. Both security, and drive encryption on the device are now, and always have been disabled. Security, and encryption in this case are not an issue.

I just want to know how to get this configuration to work. I saw another post here where someone did something similar, and their only issue was that they couldn’t put the VCD onto the smaller drive.

The owner of this device has never ever used the VCD, or the software on it for any reason, and doesn’t bother with security, or encryption on the drive.
