I have actually found the whole thing to work rather well so far. It's just that I would like the time capsule and attached drive to mount automatically so that when itunes opens it automatically finds the library on that tc's attached drive.
I have transferred the music via a wired connection as yes, over wifi transferring the music was going to take days. This is my setup and it would be good to get a simple yes/ no regarding the mounting issue.
The reason I have moved the music is so that sonos can access the music. I dont want to keep the music on my imac any more as the two would then not match.
Thanks for you help and assistance in advance.
