Losing your iPOD songs after connecting it to another computer
A simple instance of this is when one goes over to a friends place, likes the songs he or she has and decides to load those songs on his own iPod. He connects his iPod into his friends computer and then suddenly realises that all of his songs are gone and instead all the songs from his friends iPod get loaded onto his iPod.
Cause:
The most common cause of this is iTunes Auto Sync. This function enables users to update their iPods faster. When a computer has an Auto Sync option on all your files get replaced with the ones in iTunes. People often think that Auto Sync also copies songs from your iPod onto iTunes. This is not true. An iPod can only receive files from iTunes.
Solution:
If your iTunes in your computer still have your songs saved then you can simply connect your iPod to iTunes and again sync the two. All your original songs will get copied back. This option of course will not work if you don't have the songs saved on iTunes. In case that happens you can use an iPod data recovery to restore data to your iPod. These software simply help in recovering iPod data.
