If I could join in on this topic.
Having bought the Mycloud device I am very disapointed to find problems before I even get to use it!
WD Smartware does not show Mycloud as an option to back -up to, only Dropbox which I dont want to use as I will have to pay to use it and thats the only justification for buying Mycloud.
I have tried all the fixes I can find on the community website including using WD Discovery and Microsoft Netframework 4 as well as updating all the relevant software. The drive shows on my network and I can drag and drop files to it in the conventional way.
If I dont get it working today its being returned to Amazon to get my money back, I have already wasted some hours on this just to save a few pound expenditure.
Have emailed WD support and am awaiting reply but if there is something I have missed please tell me about it.
