You can't, programs like iTunes, or any other programs can only be located on your main, drive where the operating system is. You can only use external hard drives for storage. If that is what you mean, you want to store your music there, you just navigate to the folder in iTunes library settings.

sir you can transfer the music files using any of the flash drivers. you can also download the songs to your computer from your ipod.

It's a good idea to regularly back up all important files on your computer to an external source to prevent data loss. Your iTunes music, videos and other digital downloads are stored in separate files within the iTunes folder. However, if you consolidate them into a single folder, it's easier to back them up to an external hard drive.

Launch iTunes. Go to the program's Preferences menu. Click the "Advanced" tab. Check the box next to "Copy files to iTunes Media folder when adding to library" and click "OK." Click "File." Select "Library" and then "Organize Library." Check the box next to "Consolidate Files" and click "OK." Close iTunes. Connect your external hard drive to your computer. Find the iTunes media folder on your computer's hard drive. Drag the folder to the icon for your external drive to copy your iTunes media.
