Thanks for the reply.
I have two questions.
I tried relocating in Lion HD drive first of all using iTunes 10. I managed to get it working which is good, but for some reason only around 30GB of the computers audio contents was moved despite appearing to move the complete folder. This left about 80GB of "Audio" which I behind on the Lion HD drive.
1.
I located the this extra 80GB in Finder under Music and dragged and dropped in the Data HD. Problem is how to know what these files are and what to do with them, I would like to know how find out identify the folder and its contents. How would know if they are all uduplicate files of new iTunes Media folder or not?
2.
I then tried "relocating" the iTunes media folder in "Snow Leopard HD" drive using iTunes 11. I want it to be sharing the same iTunes media folder as Lion HD uses (the one on Data HD). I went through the relocation instructions and nothing, same library yet a appears to be a diferent one under Preferences. How can I get Snow Leopard HD to use the same iTunes Media folder?
Thanks, all help appreciated 🙂
