I’ve tried everything suggested to no avail. Numerous turning-offs. Correct sequence of loading i-Tunes and Sharepod then plugging in the device. I-Pod visible in i-Tunes bot not Sharepod. Except I can’t find anywhere in i-Tunes 12 where it says to Enable Disk Usage. So I’m stumped. The i-Pod contents appear briefly in Sharepod then disappear. Any help appreciated.
This is most likely due to not having disk use enabled. You’ll find that setting in iTunes by simply selecting your iPod in iTunes, and the first screen that comes up will have a checkbox for it. Here’s an AppleCare article that discusses it and has a screenshot:
