I've had a 3 disc setup Working for 12-18m, I've been given a 4th disc by a friend and not been able to add to my setup.
Here is what I've done so far:
I also added the 4th disc into the back of one of the other discs and can can see the disc in the device list, so I presume it's working ok.
I simply can't get the setup to recognise that I've added a new disc.
Any ideas on what I can try next or can someone point out what I've not done correctly
