So, I had everything on my Drobo and outgrew that so I bought a DroboPro. Copied everything over to the DroboPro. Went to iTunes and changed my library location to: DroboPro -> iTunes It updated my library for a few minutes, but all the files still pointed to the ones on the original Drobo. So I went to my user folder -> Music -> iTunes and saw two files: iTunes Library iTunes Music Library.xml The first is un-readable code, the second is just XML so I did a find and replace for: <key>Location</key><string>file://localhost/Volumes/Drobo/Music/ to <key>Location</key><string>file://localhost/Volumes/DroboPro/iTunes/ But when I open iTunes, it's still looking for the files on the original Drobo. What do I do? Also, I wanted to try and restore the .xml file back to the original but for some reason Time Machine doesn't seem to back that up. Why wouldn't it back that up?
