Switching backup drives
Until recently, all my iTunes songs went directly into a file on an external hard drive. That
hard drive was quite small, so I recently copied my 27,000 songs onto a new, larger backup drive.
All new additions have been dedicated to that new drive.
However, I cannot play any "pre-change" songs without having the old drive hooked up, too.
If I only have the new drive hooked, I get the "question mark / cannot locate" on all older
songs. Post-change songs play fine. All songs are clearly in the new drive. If I go into the new drive and click on the "unlocatable" song, it opens and plays as if it's a new addition. So, when I hookup the old drive, too, I now have duplicates.
What am I doing wrong?
