I just lost over 4,500 songs on my Ipod. . . ---------------------------- So I've been having trouble with my Ipod recently, ever since I've downloaded various iTunes updates (7.7). . . For a while, the Ipod library would not show up on itunes, and yet would be connected to my MAC, and showing up on my desktop . . .I've seen messages that stated my ipod was corrupt, to the USB port is weak, to not being able to find the ipod and you should restore At one point the ipod just stopped playing the music that was clearly on there when disconnected from the Mac . . . I fixed it by plugging my Ipod into my PC, and it downloaded an update onto my actual iPod and it started working again TODAY, after playing music all day long, A song I kept clicking on would not play, and would cause iTunes to freeze, so in frustration, I turned the MAC off, disconnected the ipod and poof all information erased...plugged into Mac, itunes says the following: "iTunes cannot read the contents of the iPod "JUSTIN'S IP". Go to the Summary tab in iPod preferences and click Restore to restore this iPod to factory settings." WHAT SHOULD I DO??????
