I'm in the process of ripping all my CDs to my PB and I'm looking for some suggestions on the eventual storage and playback of my music. I think what I would like to do is store it all on an external hard drive and playback through the stereo with Airport Express. I would probably get a iPod Mini or Shuffle to take music with me. My main concern is backing up my music files in case something awful happens to the external. I'll eventually have close to 100 GB of music files, probably more in the future. Anything wrong with this scenario, or do you have any suggestions? Thanks in advance.
