This is a two part question but both questions deal with different aspects of the same "problem". I switched to Mac just a little over a year ago, so my knowledge is still in the growth stage. Even though I switched I could not transfer all my files to my Mac at the time as I could not afford the nessacary hard drives. Now I have the money and want to move my files.... What I have is a huge amount of music... I have 780gb that needs to come off my old PC server so I can throw that POS away.... last count over 4500 complete full length albums.... Four years of college and borrowing every music collection from every friend I came to know at school and my best friend doing the same thing got us this music collection... So what I need to know is this... if I buy (3) 300gb HD and stick them in my G4 running 10.3.3 can I just run a software raid and have them show up as one 900gb drive? If it is possible what are the exact steps I need to take... Then if that is possible can your iTunes music library not be on the hard-drive that your OS is on? Then will iTunes recognize all the songs? I have seen at www.iTunesregistry.com a guy that has 50,000 songs listed (my current libray of my favorite stuff that I must have is ranked 41st)... About a year ago I though I read on some forum a post from a guy saying his iTunes maxed out at 33,333 and that it was some weird Unix problem... I have no idea if that is true and that is why I'm asking.... Thanks to anyone who can answer any of these questions!
