Hi,
You're welcome :smileyhappy:
Regarding the USB option, Recovery Manager will only recognise a USB Flash Drive as an option to create Recovery Media on - a USB HDD will not be recognised and you will not be able to create a recovery image on it.
You can use the method described in the following link to clone the usb flash drive.
