Yes, I wasn't very specific.
I will respond with more of an explanation and refer to your links - thanks.
I originally copied files directly from what I assume to be the default spot on my start up drive:
User> iTunes> ITunes Media Music> Music> to a folder I created on a separtate internal drive Volumes> Internal HD> iTunes Media> Music
Unfortunately, after files were copied I deleted the originals and emptied the trash.
I did then opened iTunes preferences> advanced and changed the location reflect where my files were just copied. None of my files would play - all had the exclamation point by the track #.
I shut down itunes and restarting expecting evertying to be fixed... no go. I repeated the process a time or two - once after copying all files back to the original folder. Nothing doing. Trying to look at the orginail folder arrangement on my start-up I noticed some (seemingly) odd things. For example, within my iTunes Media folder I had Books, iPod Games and Music (among a coupld other folders). WHen I clicked in "Music" folder, again there were Books, iPod Games and another Music folder. Going inside this 2nd Music folder is where my actual "music files" were housed.
After getting a frustrated at trying to "re-direct" my iTunes to read my files I just selected the entire library of music within iTunes and deleted it - at that point thinking it would be easier to recopy, the copied files from the 2nd HD.
There had previously been some discrepency between what I saw in iTunes and what i saw in my "music" folder So I began the process of dragging and dropping one artist at a time. I noticed some, not all, of my artist files would disappear after dragging into iTunes. After loading the "B's" into iTunes I realized that at least half of what I moved over was no longer in my folder... Took quite a while before I realized there was now a 2nd "Music" folder within my newly created "Music" folder. I then noticed all that remained in my "original" folder was anyting that had WMA files that I had converted from a friend - all the MP3/M4A files were moved to the 2nd folder.
I apparently don't know how this works, but it seems like there should be a way for iTunes to automatically load content from this folder.
So after your comments I decided to re-re-copy from my 2nd HD to the original spot on the start up. Then I copied the entire iTunes folder to the HD #2, redirected iTunes to look here, closed the program, started up pressing option and selected the previous itunes library created today, modified moments before, selected this file. I still have nothing in iTunes except a few files I copied myself.
So, worst case scenario I'll just have to drag and drop by hand and dea with it.
But I just feel like I have to be missing something - and why the need to create a 2nd music folder?
Just seems like I either have something very screwed up or this is a bit more complicated than it needs to be?
Thanks for your response - I will keep looking into it.
