Will all the songs on my ipod be wiped off if my itunes is now empty?

Question

My lap top's hard drive crashed and i've lost all the data that was ever stored on it, including all my music and itunes. i've since reinstalled itunes but obviously have no music within it. if i reconnect my ipod which currently has all my old music on it, will it sync with the new itunes and cause all of the old music to be wiped from the ipod? any answers on this would be much appreciated!

Answer 1

Connect your iPod to your computer. If it is set to update automatically you'll get a message that it is linked to a different library and asking if you want to link to this one and replace all your songs etc, press "Cancel". Pressing "Erase and Sync" will irretrievably remove all the songs from your iPod. Your iPod should appear in the iTunes source list from where you can change the update setting to manual and use your iPod without the risk of accidentally erasing it. Also when using most of the utilities listed below your iPod needs to be enabled for disc use, changing to manual update will do this by default. Check the "manually manage music and videos" box in Summary then press the Apply button: Managing content manually on iPod
You can also use a keyboard command to prevent your iPod auto-syncing with iTunes. While connecting the iPod to the computer on Windows with iTunes 7 installed hold down the Control and Alt keys (or Shift + Ctrl keys in older versions). This will stop the iPod from auto-syncing with iTunes and the iPod will appear in the source list. Wait until you are sure the iPod has mounted, and that it will not auto sync and then you can let the keys go. This may take between 20 to 30 seconds depending on your computer: iTunes 7 Keyboard Shortcuts for Windows
Once you are safely connected there are a few things you can do to restore your iTunes from the iPod. If you have any iTMS purchases the transfer of purchased content from the iPod to authorised computers was introduced with iTunes 7. A paragraph on it has been added to this article: Transfer iTunes Store purchases using iPod
The transfer of non iTMS content such as songs imported from CD is designed by default to be one way from iTunes to iPod. However there are a number of third party utilities that you can use to retrieve the music files and playlists from your iPod. You'll find that they have varying degrees of functionality and some will transfer movies, videos, photos, podcasts and games as well. Have a look at the web pages and documentation, this is just a small selection of what's available, they are generally quite straightforward. You can also read reviews of some of them here: Wired News - Rescue Your Stranded Tunes

There is also a manual method of accessing the iPod's hard drive and copying songs back to iTunes on Windows or a Mac. The procedure is a bit involved and won't recover playlists but if you're interested it's available at this link: Two-way Street: Moving Music Off the iPod
Whichever of these retrieval methods you choose, keep your iPod in manual mode until you have reloaded your iTunes and you are happy with your playlists etc then it will be safe to return it auto-sync. I would also advise that you get yourself an external hard drive and back your stuff up, relying on an iPod as your sole backup is not a good idea and external drives are comparatively inexpensive these days, you can get loads of storage for a reasonable outlay.
