iTunes Media Folder won't switch location from external hard drive
So for the last few years I've had my iTunes library stored on an external hard drive (a LaCie Quadra), but I'm out of space, so I got a new one (a Lacie Rugged). However, when I go to change the iTunes Media folder location to the new iTunes folder in my Rugged, it's not switching over, and in fact what's even weirder is I've just discovered no matter where I set the iTunes Media folder location to, my iTunes library will only play from the iTunes folder in my old Quadra. I've Reset it numerous times, and even set the location to the Desktop (on which I have no music), yet it still is playing from my Quadra. It's as if it's locked onto it.
Does anyone know what's going on here and how to fix it? I should note I think I did get it to switch to my Rugged for a bit, as the first time I switched the iTunes Media to my Rugged (which at the same time my Quadra was still connected) I bought a song, which is no where to be found on my Quadra. But ever since I disconnected the Quadra, this problem started. Also, to transfer my files from my Quadra to the Rugged, I connected the Quadra via Firewire 800 and the Rugged via USB, and I intend to use Firewire with my Rugged from now on. Could that affect what's going wrong here? And FYI, every time I've connected to the Rugged, it does go through the Consolidate Files process, but that hasn't done anything.
Thanks
