How do I cancle an ipod account on one computer and set it up on a new comp

Question

OK so when my mother first got her ipod she didnt have a computer so she had to autorize her ipod on my brother comp, but since then I purchased a computer for her, I have my own ipod touch authorized to this new comp. Every time I try to sync songs from the new comp to her ipod it doesnt work right because I keep getting my songs synced to her ipod.
I figure that (a. I need to take her ipod off of my brothers computer. (b.reauthorize her ipod to the new computer. And (c. creat an entire new library just for her ipod and songs. How do I go about this?

Answer 1

iPods don't have accounts nor are they authorised. There are a couple of ways to create a new library. It's possible to have multiple libraries in a single Windows user account. To create or access a second (or more) library, hold down the Shift key in Windows when launching iTunes. In the resulting dialogue you will get the option to create a new library or navigate to the other Library.
Note: You can only have one Library open at a time and iTunes will default to the last library opened if you don't use the keyboard command to choose one. The new library will be empty until you add content to it. To get back to your original library you need to close iTunes and open it again while holding down the option/shift key, this time choose to open an existing library and navigate to its location. Multiple libraries can prove tricky when using iPods, if you don't use the keyboard command you can risk syncing to the wrong library: Using multiple iTunes libraries -Windows
Another option is to create a separate Windows User account for each person on your PC or Mac. Different user accounts by definition would give you completely separate libraries. Each account has it's own iTunes folder, Library and iTunes Music folder and you load it with CDs etc just as you did with your original one. The iPod can be set to update however the owner chooses, sync all, manual or sync specific playlists
I don't use Windows so I can't give you a step by step on that one, however I can point you to another web page which should help you out. You can read about Windows user accounts here: Create A New User Account In Vista
You can also fill the library by copying the songs from the iPod and putting them into iTunes.
1). Connect your iPod to your computer. If it is set to sync 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.
2). When your iPod appears in the iTunes source list change the update setting to manual, that will let you continue to use your iPod without the risk of accidentally erasing it. Check the "manually manage music and videos" box in Summary then press the Apply button. 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: Managing content manually on iPod and iPhone
3). Once you are connected and your iPod is safely in manual mode there are a few things you can do to restore your iTunes from the iPod. iTunes will only let you copy your iTunes Store purchases directly from an iPod to the computer, you'll find details in this article: Copying iTunes Store purchases from your iPod or iPhone to a computer
For everything else (music from CDs, other downloads and including iTunes purchased songs and in some cases, videos and games) 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. You can read reviews and comparisons of some of them here:

There's also a manual method of copying songs from your iPod to a Mac or PC. The procedure is a bit involved and won't recover playlists but if you're interested it's available on page 2 at this link: Copying Content from your iPod to your Computer - The Definitive Guide
4). 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.
