Occasionally an iPod may freeze or fail to respond to your commands. It happened to me today, when my computer froze and I had to reboot. This can happen for a number of reasons and does not necessarily indicate a serious problem. My iPod simply was frozen at the “Do not disconnect?screen as if it was syncing (but it wasn’t plugged in).Sometimes an iPod needs a restart much like the way your computer needs a reset once in a while. Restarting the iPod is a simple procedure that will not erase any of your music, data files, or customized preferences.

• iPod 1G to 3G: “Menu?and “Play/Pause?
• iPod 4G (includes Photo, Nano, Video, and Mini): “Menu?and “Select?
• Shuffle: Turn it off, turn it on. Done.

Easy stuff. Now when you turn your iPod back on, it should work like normal. No dataloss!
