Hey everyone


I just reformatted my computer and now i can't sync my ipad with my itunes.

it says


" The Ipad -NAME- is syned with annother itunes library. Do you want to erase this Ipad and sync with this itunes library?

An ipad can be syned with only one itunes library at a time. Erasing and syncing replaces the content of this ipad with the contents of this itunes library"


Of course i don't want to erase everything on my Ipad. How can i just sync my ipad to my itues now?


Thanks in advance


iPad 2, Windows 7, itunes

    You cannot.  You reformatted your computer, making a new itunes library.



    Have you used your backup copy of your computer to put everything back?

    "i didn't think you needed to back up itunes."

    Why did you think this?

    You should always back everything that you do not want to lose.


    You can transfer itunes purcahses from your ipad.  Without syncing:  File>Transfer Purchases

    It still can be fixed possibly....

    You can move the files you do want to keep out of itunes reach for now, do the sync then move them back into the folder afterwards.


    Log into itunes from the ipad and see what shows there.


    When you did the computer, you had to set everything back up on the computer but you should have used all the same data, info you had before to set it back up. If any of the data is different that may be why your getting that error. If its not the same, exactly the same info data as before then try setting itunes back up on the computer with the correct data, info.  (data, info = id, passwords, account info ect)

    you can right click on the device name in the left hand sidebar and click "Transfer Purchases".  You will get a prompt asking if you want to transfer purchased apps from the iDevice to your PC.

    You've probably already found an answer for this issue, but I will post this for any other person this becomes relevant for should this occur to you:


    upon plugging the device into your computer/laptop, it will give the message you were stating. Do not allow it to sync to yur current library AT ALL. Rather, click onthe summary tab that displays when you've clicked on the iPod/iPhone on the left side menu bar. The summary and all over information will be in the right hand side of the screen.


    Once you are in the SUMMARY TAB: click on the backup there are three rows: iPod, Version, and lastly, OPTIONS. There are four selection boxes. Click on the last box labeled "Encrypt iPod/iPhone backup" or you can also select this option by clicking on the change password box. Put in your iTunes account password--it seems to be synced that way and always works. If you are prompted to update iTunes software in the process, do it. It is better to have the updated version and have it function smoothly during this transition.


    This will backup everything on your device without losing your information permanently.

    Once this step is complete, you will indeed need to restore he device to factory settings. Please note, this is the only systematically correct method I know of to successfully re-register your device back into your library.


    After factory settings are restored... TIME TO PUT YOUR MUSIC/Apps/Etc BACK IN.


    This will take some time and your device will also be caused to shut off and restart on it's own.

    A New screen appears asking you to set up your iPod/iPhone.


    You will see the back up on your screen and should select the restore from back up option listed there. You will be prompted to install your password from the last time you backed up your computer (as stated before, this should have been the iTunes account password for the sake of consistency)


    This backup too should take a few minutes.



    You should be ready to go after this.

    I had exactly the same problem and I found a solution (


    I discovered my iPhone Library Persistent ID following these instructions: tent-id/


    Then I used iTunes DB Cloner ( to replace the empty iTunes library Id with the one from the iPhone.

    Just something else that no one has touched on that I found out the hard way the last time I did some similar.  The data IN each app is not saved in the any iTunes or Time Machine backup.  A lot of apps have their own method of creating backups with it as an email back up or saving a file to a cloud back up.  I have a lot of apps with critial data that I lost during my last upgrade from the original iPad to the iPad2.  The genius bar guys at the Apple store confirmed that our Macs and iTunes only copies and backs up the app itself but not data or settings that we put in it.  Unless something has changed in the last 6 months since I have done this, not only do you have to continue to back up your Apple devices but also the idividual apps that have a lot of data in them that you don't want to lose.  I hope this does change soon because it is labor intensive to continue to back up info on apps that I use continuously on top of backing up the devices themselves.  In short:

    back up your apps before deleting iPad info and resyncing.

    I too had this problem, where my hard drive crashed and I was getting the message that my ipad was synced with another itunes. I right clicked the ipad name and clicked "transfer purchases" then it asked me to authorise this computer and asked for my apple id password. Once I authorised it synced with the "new" itunes library. You can authorise up to 5 computers!!!

    Use a product called Touchcopy to backup your device to the new itunes account.

    Just to clearify, there are device backups.


    iTunes > Preferences > Devices > Device Backups

    I'm shocked there is no option to just copy files from your PC to your iPhone without all the hassle.

    This should be a simple task.


    Cupertino guys, wake up
