There are many people who have been using iPods from years, but do not know how to transfer data from iPod to computer. This may probably be because of not having a need to do so. All iPod users know how to transfer files from their computer to the iPod, but some do have a misconception that copying audio from the iPod is not at all possible.

1.Connect the iPod to your PC. If iTunes starts syncing (ie erasing) your music automatically, hit the X in the upper right hand corner of iTunes display, to the left of the search box, to stop it.

2.In Control Panel, Portable Media Devices, double-click your iPod.
In the Tools menu -> Options, in the View Tab, check "Show hidden files and folders."

3.Navigate to the Music folder. On my 2nd gen 'pod, the full path isPortable Media Devices\GINA'S IPOD (F:)\iPod_Control\Music
Select all the music folders, and drag and drop them into a folder on your hard drive, or directly into iTunes.
