I bought a 4TB (2x2) duo drive to replace a Seagate drive that simply cracked up after about 18 months. The store told me everything I saved on one drive would be copied automatically to the other. I reloaded all my network data - and was surprised to see I still had over 3TB left … the drives were being seen together, and not seperately. I had followed the install instructions very carefully .
Usual solution - read the manual. I ultimately found, tucked away, that I had to opt for a RAID Mirror set-up: my point is this -
Nowhere in the Set-up procedure was I offered the options on how the drives were to be used.
Since this is a major reason - as promoted on the box - for purchasing a dual drive system, it should be one of the options in the WD set-up procedure, surely?
In my book, a serious slip in what otherwise appears to be an excellent piece of hardware and software.
I should add that I use computers (for video editing), but that doesn’t mean I know how they work!
