iPod nano 6th gen won't synch with iTunes 12.1.1
Since I upgraded to iTunes 12.1.1.4 on my Windows 7 PC a couple of weeks ago, I have been unable to synch my iPod nano 6th generation (SW version 1.2) with iTunes. I have followed Apple's instructions to uninstall all of my Apple SW, restart my PC, then install iTunes again, restart my PC, then attempt to synch. I get the same failure I had before re-installing iTunes. My iPod connects with the PC and displays an icon on iTunes. I can select the iPod icon on iTunes and select the menu items under "Settings" and "On My Device", and all of the music and podcasts stored on my iPod are displayed. But when I select "Synch", I get the following two error messages:
1. The iPod "Larry's iPod" cannot be synced because it cannot be found.
2. The iPod "Larry's iPod" cannot be synced. The disk is not available.
I never had such problems with any prior version of iTunes during the several years I have owned my iPod. Help!
Thank you.
iPod nano, iOS 1.x
