THis has happened to me 4 times as well. I have over 47000 songs in my Library, located on an external hard drive. For some unknown reason, the Library location keeps reverting to the default library. All my music is still on my external, but iTunes doesn't see it anymore, because it has thrown my library files into the recycle bin and only looks for music on my default C drive. It wouldn't be a big deal, but 47000+ songs don't fit on a 160 gb classic so my months and months of rating songs and unchecking music is wasted because of this glitch. I've restored my iTunes music several times now, but haven't even gotten close to syncing my IPod again, because just when I get close enough, iTunes defaults back to the wrong library.

If you've split the media folder to a separate drive, but have the library files on the internal then you might want to consider normalizing your library so that everything is self-contained on the external drive.
