Thank you so very much for reading this. I am still new to iTunes and Macs and so appreciate your thoughts. I have the original 250 gig internal hard drive that came with my G5 PowerMac. Because I burn at lossless (no snippy comments, please) I ran out of space. I've bought a new 500 gig internal hard drive to put in the second bay/port in my PowerMac. (The second bay/port is currently empty.) I plan to migrate my current 190 gig iTunes library to the new 500 gig drive and begin ripping and buying to the new drive; in other words, the new drive will be my new library, period. I greatly appreciate any thoughts on the following two questions (or a reference to other posts on these topics): First, how do I tell my Mac to move my existing iTunes library from the old/original drive to my new drive? Second, how do I teach iTunes to only refer to the new drive when looking for/dealing with my library? Again, thank you for reading this. I appreciate your time and comments.
