iTunes - where does it get it's Library info?

[hazmat]

I switched drives for my OS X install, and for some reason some of the songs in my iTunes Music Library.xml file are referencing my old drive. I went in through the shell with vi and did a global replace to put in the new drive info. No prob. Upon quitting iTunes the next time I open it, the file is reset to the old drive into. Where is iTunes getting this from? Very irritating. I tried renaming the file iTunes 3 Music Library, but no change.

Thanks.

was iTunes running when you edited the file? if so, itunes may have overwritten it when it quit. if not, weird...

No, it wasn't. VERY weird, huh?
