iPod music + playlists erased after update
So, i've been manually syncing my ipod to my iMac for years, and never had a problem before.
I had created about 8 playlists in my iPod, with about 35gb of music. This music has been on my ipod for the past 5 months.
Yesterday, I installed the new iPod update (iOS 8.2). Everything was fine. Then after the update was done & my ipod restarted, I synced it manually (again: something I do on a weekly basis - removing / adding songs to my ipod, or syncing new photos, etc - basic stuff), and after ejecting it & connecting to via bluetooth to my car's music system, I realised all my musc was gone... playlists and all.
I came home, synced my ipod to my iMac again... at the bottom of iTunes, it showed that my ipod was empty. But all the playlists were visiblewhen viewing my ipod via iTunes - in the "devices" section, and even when I clicked on the iPod icon at the top left of iTunes, which then displays the "Summary," "Music," and "On My Device" sections.
The playlists are there, the songs' names are showing up, and at one point my iPod went from empty to 3/4 full again. Now it's empty again. And when I try to play any of the songs on my ipod via iTunes, an exclamation mark shows up on the left of the song title.
I'm confused. What the **** just happened? Did I do something that cause my music to be wiped out, yet somehow still be visible when viewing my ipod via iTunes?
Any help would be greatly appreciated. Thank you in advance!
