If you are attempting to copy your music library to your pc using windows networking and you are receiving errors this may help you. I have found out the hardway (took me about an hour to figure out) that you must make sure your directories are compatible with windows file system rules. basically, on a mac i am able to have a file that has the artist as T.A.T.U, this is fine . But it also means that my library contains a folder that has .'s in the name. This will piss windows off. (ie: it won't work)
So do yourself a favor, before attempting to copy your music library over to a pc, do a search for all artist and album names with . 's in them and rename accordingly. Every artist and every album in your collection has its own folder with that name and this causes the problem.
Hope this helps users backing up prior to formatting for Panther install tomorrow.
