USB Expansion

i dunno about you guys but i need the usb to be able to expand my cloud like the original my cloud, i have a 12 tb hard drive i had connect with the 6tb hard drive now im stuck without it,

You can import, copy or backup USB content on My Cloud Home but it doesn’t allow to copy its content on USB device so can’t be used as to expand storage. You can refer USB limitations from below link for more details.
