I would second polykick's comment above. I have had WD for many years, and run it under windows.
I have a Pi3, and want to use it for a reduced cost installation at a remote site (the hanger at the airport) and don't want a lot of equipment sitting there or the expense to go with it.
I am not as mentally facile as I used to be (I can barely follow murder mystery novels any more (just kidding)) so to have someone tell me that I need to run a virtual OS on RPi3 and load a version of WD into that leaves me a wee bit wondering.
May I ask those who are happy with RPi3 if the right way to do this is first get RPi running, second load some mysterious piece of software onto RPi which you are calling a virtual OS (are there some or just one to choose from?), and thirdly, then use that to load WD and configure and run it just the same (maybe not as fast) as I would on my Windows 7 machine?
Sounds like a summer project. Thanks for any clarification. Dale
