I'm looking to have two partitions on my computer that i can easily access whenever i need. I am a DJ and store all of my music on my computer. I want to have one partition just with my music and DJ software on it and the other with the rest of my day to day computer stuff, files, applications, movies etc... I have a WD my book hard drive (if that helps) and i use a 13 inch macbook pro. Any help or other suggestions on what i should do that anyone has would be appreciated. Thanks!
