I believe it's for the "cloud" functions (e.g. accessing away from home.
the internet is full of reports of this software being pretty crappy! - meaning you'll probably need to remove it, and use FTP or something to access files remotely using no-ip or dyn DNS to get a domain name (unless you've got a static IP)
I have an irrational hatred of the Western digital cloud devices.
this is why.
I work in IT.
clouds are used in network diagrams to represent the unprepresentable, like the internet, with all the routes that can be taken, and sheer amount of devices, sure you could map it, but it's probably going to have changed before you finish.
with VM hosting, (cloud hosting) at one data centre, it's cloudy because the VMs can run on any number of hosts, and you don't care.
with storage it's generally stretched over multiple controllers (and multiple disks) (and you don't care what disk or disk controller you're connecting to
or all of that is replicated across several data centres. (and you don't care what DC you;re connecting to!)
being a "cloud" implies redundancy, and ability to access even when shit hits the fan.
not a single disk (or bunch of disks) running on a single controller, plugged into a single outlets attached to a single feed from the grid with a single network connection to a single home broadband with a single ADSL connection in it, in a single location.
Where anything from a power cut, to your cat knocking over the undrank coffee that you left on the side can take your western digital "cloud storage" offline!!
because, lets face it you could draw that in detail on a post-it note.
(it's just the cloud name I've got a problem with. the actual produce is neither here nor there.)
you or I could build something better for not a lot more, but they are simple plug in devices, not buy components configure services devices...
Rant over, - there is no fix. you just cant use the software that comes with it!
