Thanks for responding - let me try to answer some of those questions in detail. I think the confusion was me trying not to give too much detail.
So my initial set up was iTunes with all files in the external drive. When the hard drive crashed, I had to reconstitute that set up. Enter Apple Care.
What really happened with AppleCare was I had to work with 3 different reps - the rep I got kept having the next day off. (They were all pretty helpful btw - they just had different opinions about how to get this done.)
So the first rep dragged and dropped everything from my external hard drive back into iTunes (which had obviously been empty since the hard drive had been reinstalled).
The second rep didn't think we needed to copy all those songs into iTunes, so asked me to delete all 70,000; when I asked her if I should send those files to the trash, she said yes and was hurrying off to another call but was calling me back to check in, in 30 minutes. When she called back, she was lightly panicked and asked if I had emptied the trash. I had considered it, but hadn't done it. Then she asked me to check my external drive and lo and behold it was mostly empty. (That's when I started to panic.)
We had to take the files from the trash and put them on the desktop. We tried to drag and drop them directly back into iTunes but that didn't work for some reason.
So we created a file on the desktop that now contains all the files that were taken out of the trash. We started dropping files from the desktop file into iTunes 5-10,000 at a time. Doing that added copies to the external drive and filled it back up.
Rep #3 came next. The library was now full but there was no ratings, playlists, etc. He found the library .xml file (thankfully!). We restarted using that .xml which repaired most of the problems.
Still, there were these 2000 exclamation points. He told me that I had to go back one-by-one and fix each.
I found an article on here that suggested I create one playlist by dragging and dropping everything in my library into a playlist - called it "Not Missing." Then I created a smart playlist of all songs not in the Not Missing file - I called it "Exclamation Points." So all the songs with broken links are in this playlist. And for the last week, I've been going song-by-song trying to repair them.
When I click on the exclamation point, one of two things happen:
- Sometimes a copy is found on the external drive, but iTunes isn't finding it for some reason. Whenever this happens, there is always also a copy on the Desktop file. I have usually been linking iTunes to the copy on the external drive, but NOT ALWAYS. Because for some reason, when I choose the desktop file, iTunes asks me if I want to look for other missed files at that location - and, usually not, but sometimes it will find a bunch of other related files automatically, thus saving me having to find those files myself manually.
- Sometimes a copy is ONLY found in the Desktop file. So I link to that in that case.
What I've discovered, now that I've done about 700 of these "repairs" is that the group of songs that I linked from the desktop file are not copying into the external drive when I click "open" during the "location" process.
My current solution is that whenever I find a song that is only in the desktop file, I cancel out of the "location" process through iTunes and go into Finder, locate the file in the Desktop file, and then drag and drop it into iTunes. That way a copy goes to the external drive.
So my problem is how do I go back through those 700 other files that I've connected to iTunes and figure out which of them are linking to the desktop file (and thus have not created a copy in the external drive). Because my ultimate idea is to delete the desktop file since it's mostly copies.
Sorry to go on and on, but I hope that helps you help me.
Any ideas how I can either do this whole thing more efficiently or find which songs I've just linked to the desktop file and copy those songs into the external drive?
