See the dedicated subforum for the Pro Series where people more knowledgable with that device may be able to assist. This subforum (My Cloud) is generally for the single drive My Cloud device that has fewer features/options than the multi bay devices.
Also search, using the forum search feature (magnifying glass icon upper right), that subforum to see if there are past discussions similar to your question/issue.
Thanks Bennor. I changed the posting section.
Unfortunately before by using the search button I found that no recent post where actually saying it is possible or impossible.
Thanks again
