ITunes is forcing erase and sync

Hello
I am having a problem with my iPhone syncing with iTunes. I just downloaded an album and tried to sync it to my iPhone and iTunes is telling me that my iPhone is currently synced with another iTunes library. The only library it's synced to is the one I am currently connected to.
Is there anything that I can do to fix this or am I pretty much looking at having to reload all of the albums on this iPhone now?

Is it possible that you've rebuilt your library following an error? If so reverting to an older database might help. Alternatively the user tip Recover your iTunes library from your iPod or iOS device should show how to associate the device with the current library. If you have all the media already the essential steps are 3 & 6.

Copy your iTunes Library from your Old computer, or it’s Backup, to your New computer...
See Here for one way
iTunes: How to move your music to a new computer
Or...
From your Old Computer... Copy your ENTIRE iTunes FOLDER to an External Drive... and then from the External Drive to your New Computer..
An Added Bonus is that you will then have a Backup of iTunes...

ERASE AND SYNC PROBLEM

My girlfriend wants to use my mac to sync her ipod touch. It is already partnered with another mac and consequently when I connect her ipod itunes offers to erase and sync it. How do I get around this problem? She clearly does not wish to erase her ipod.
On a general note, why is itunes loaded with this kind of control freakery? My mac, her ipod - surely it is up to us to be responsible and 'law abiding'. I hate it when corporations exert this kind of control over my things, I bought them, I own them - it should be up to me how I use them!

after connecting ipod cancel the auto sync then go to the ipod,un tick in all auto sync like music, video, movie, photos etc aftr that in option click there manually manage..aply ok..
thnx..

No, it will sync the ipod to the content of the MBA which presumably has nothing on it (= erasing content of iPod and replacing it with nothing).

do not confuse moving your whole folder and library with moving just media files as in
iTunes for Mac: Moving your iTunes Media folder - http://support.apple.com/kb/HT1449
Quick answer if you let iTunes manage your music: Copy the entire iTunes folder (and in doing so all its subfolders and files) intact to the other drive. Start iTunes with the option key held down and guide it to the new location of the library.

HT1414 having bought a new MacBook, I wanted to Sync my iPhone4 to it, but it insists the only method to do so is to "Erase and Sync" or "Cancel" which leaves no option to just use iTunes on the new MacBook Pro - how annoying is that???

I have had the iphone4 for 2 years now and I bought a new MacBook Pro, opened iTunes and it knew I already had other machines with iTunes sync'ed with it but it still insisted on offering one option or sync'ing with new MacBook - "Erase and Sync", which means deleting EVERYTHING on the iphone. What if I want my iPhone to dictate and get iTunes on the Macbook to match up with the iPhone??? Or at least get iTunes to relate to what my iTunes account obviously has on it and update that way. Come on Apple, as per usual, very pretty but not very practical!!!

You can only sync everything with your one syncing computer/iTunes library. Yu can:
- Make this your syncing computer by:
Syncing to a "New" Computer or replacing a "crashed" Hard Drive: Apple Support Communities
- Use the manual method to copy music and videos from any computer/iTunes library to the iPod. See the manual method included here:

I just bought a new computer, now itunes tells me I can only sync with one computer. It only offers me the choice to erase and sync. I do not want to erase my ipod, I just want my music on the new computer. Can't I just transfer the songs from the ipod

I just bought a new computer. Itunes only offers me the option of erase and sync, as I can only have it sync'd with one computer. I want to move my music to this computer from my ipod. Is this possible, or do I have to go back to my cds and upload everything from there? I just want to be able to move my music from my ipod to the new computer.

You need to transfer your iTunes Library from the old computer to the new one - then you can carry on syncing as normal. You can't move non-purchased music from an iPod to iTunes using iTunes. For purchased music, choose iTunes > File > Transfer purchases...

How do I save songs from old version of iTunes that I have on my iPod, as new verson is asking me to erase and sync before I can do ANYTHNG, and I don't want to lose my music!

Hi everyone,
Can anyone help?! Pleeeeease
I have recently bought a new computer (new operating system Windows 7) and downloaded the new iTunes. When I tried to add a new song to my iPod shuffle, it said I had to ERASE and SYNC my iPod to the 'new' iTunes, and there seems to be no way around it. I DON'T repeat DON'T want to lose all my music on my iPod, as I no longer have that music/my old laptop with music on, and there are so many songs on it that it would take like forever to re-download EVRYTHING.
I tried saving playlist on in iTunes, but it only saves it as a Read only file, there are no MP3's in there.
I'm tearing my hair out over this!
Any ideas?
Thanks,
Kitty

How you delete content from your iPod depends on how it is set up to sync with your iTunes library whether that be automatically or manually.
If it's automatically, you must reconfigure your settings so that the album you wish to remove is no longer configured to sync to your iPod. For example, if the Sync only checked songs and videos option is enabled from under the iPod's Summary tab, make sure all the tracks for this album do NOT have a tick mark next to them in your iPod. Then resync your iPod with iTunes.
Otherwise, if you manually manage your iPod's contents, you must manually remove content from it. You can do this by plugging your iPod in and clicking the small black triangle next to your iPod from under the Devices section in the left hand pane of iTunes. This will open up a submenu of content, so go ahead and click on Music. Locate the track or tracks you wish to delete. Highlight them and hit the Delete key or choose Edit -> Delete.

Hard drive crashed on my MacBook pro and had to replace drive and logic board. When I connect my iPhone and try to sync I get a dialog box stating iPhone is synced with another iTunes library, erase and sync? How do I sync with iTunes without erasing?

Hard drive crashed and had to replace drive and logic board on my MacBook pro. After Install tried to sync with my iPhone and a dialog box pops up stating "this iPhone synced with another iTunes library, erase and sync?". I checked the manually manage music and videos box because I don't want all my wife's pics and music on my iPhone. How do I Sync without erasing what I have on my iPhone???

How crap is that?
It's not crap at all.
It's not that simple. For example, I've 3500 songs on my MacBook but don't want them all on my phone, so I have to manually select each song again???
There has to be a solution.
Why not simply make a playlist with the songs you want on the iPhone?
and maintain a current backup of your computer.

Windows 7 computer shut down and restarted - no memory of iTunes or other files. I want to sync my iPod 4th Gen. to the computer, but it offers erase-and-sync. Now what?

In a nutshell, the family computer, a Compaq Desktop Windows 7, has been in our family since November 2010-ish. We moved last summer, and nothing happened to it. A couple of weeks ago, the desktop had a whole "recovery-restart-etc" dilemna and no it's like new - no memory of the past files. I had iTunes (7 or 9), for only me, the only iTouch 4th generation user in the house. Basically no other Apple products. Now that I want to fix the computer (restore old photos and applications, etc) as well as move my music to the desktop itself, iTunes tells me I must update my iOS 4....? (never updated the iOS thing) So I try to do so, and iTunes tells me I have to transfer my music files to the library. Fine. I try, and since the iTouch has a previous history with the previous iTunes library BEFORE the major shutdown, it tells me to erase and sync my data! I don't want to lose all my music and repay for it, and I may be smart, but I'm not at the Genius Bar, am I? So can somebody help me? Please? Thank you in advance.

- Transfer iTunes purchases to the computer by:
iTunes Store: Transferring purchases from your iPhone, iPad, or iPod to a computer
- For other music yu will need a third-party program like one of those discussed here:
Copy music from Ipod to new computer...: Apple Support Communities
- If you have photos synced to the iPod you will need a pair program like TouchCopy or PhoneView. They also do music
- The connect the iPod to the computer and make a backup by right clicking on the iPOd under Devices in iTunes and select Back Up
- Restore the iPod from that backup. The will also update the iOS on the iPod.

I shop for for apps on my ipod touch and when i plug my ipod into itunes and it says erase and sync what does that mean?

hello all,
i normally shop on my ipod touch (because frankly i cant be bothered to plug it into itunes then shop! ) to shop for apps and song and etc. and because i have a wall charger in my room theres pratically no need to go the computer! so sometimes when im on the computer i want to use my ipod touch as well so i charge it on the pc.
well to cut the story short everytime i want to shop on itunes it comes up with this note that says "your ipod is synced with a different pc etc" then it comes up with erase and sync? so my question is what does syn mean? because im worried if i choose ok it would get rid of all my apps
- someone help me!

- It means what it says. Your iPod is synced with a different iTunes library. To transfer purchases to this computer:
iTunes Store: Transferring purchases from your iPhone, iPad, or iPod to a computer
- If you want to make this computer your syncing computer see ths previous discussion:

Was your iPod associated with a different mac or pc previously is all. And was it backed up or sync'd on this mac with iTunes previously.

Had to reinstall Lion. Backed up music to external hard drive. When I plug in iPod msg says it's synced w/another iTunes library. Do i "erase and sync" and re-add music from the hard drive?

Had to reinstall Lion. Backed up my music to an external hard drive. When I plug in my iPod a prompt msg says it's synced w/another iTunes library and asks if I want to "erase and sync" (to what is now an empty library) or "Transfer purchases". Do i "erase and sync" and re-add music from the hard drive once that's done?

You just need to tell iTunes where the library is located. If you want it back on your internal drive, copy the entite iTunes folder. Follow the instructions below.

If I back up my iPhone, then "Erase and Sync" my iTunes, will everything on my phone be lost even though I backed it up?

I recently purchased a new Macbook Pro. I am trying to add music onto my iPhone 5 from iTunes, but it isn't working. I read the discussions to manually add music, but when I try, I get this pop up message:
The iPhone “Miranda’s iPhone” is synced with another iTunes library. Do you want to erase this iPhone and sync with this iTunes library?
An iPhone can be synced with only one iTunes library at a time. Erasing and syncing replaces the contents of this iPhone with the contents of this iTunes library.
So, I backed up my iPhone to the computer, in hopes that everything on my phone would not get erased. However, I didn't "erase and sync" yet.
My only concern is that the old iTunes library I had on my old Dell computer was with a different Apple ID, so how does this affect me?
Will everything on my phone get erased even though I backed up my phone? Why can't I transfer music onto my phone with my new iTunes? I've tried everything. Please help me!
I don't want to lose all my music from my iPhone. I have like over 600 songs, and the old computer I once used is now broken so I will never be able to get them back.

Welcome to the Apple Support Communities
First, if you back up your iPhone in iCloud, you don't need a computer to restore the backup. If you use a different library or PC to sync the device, it will be erased automatically, so you have to copy the iTunes library from the computer that you use to sync the device in order to keep all your data on the phone. The answer is that it won't transfer the library to the new computer: copying the iTunes library to the new PC is enough

I want to be able to sync my iPhone 5 to my new iTunes library (new computer) and erase old music. When I connect my iPhone I have no option to "erase and sync."

So I have the iPhone 5. My old computer crashed so I ended up purchasing a new computer and re-installing and downloading all my old music and new music.
When I connect my iPhone to my new computer I can sync music but the old music still remains on my iPhone as well as the new music.
There's a lot on the phone that I don't want anymore but I can't seem to figure out how to erase it.
I don't want to restore the iPhone so I don't lose all my old messages and so forth.
I have all of the latest updates for the iPhone and well as iTunes.
If anyone has any answers to help that would be awesome!
Thanks.

Hey there,
It sounds like you are not getting the prompt to erase and sync your device. This indicates to me that Manual Syncing was enabled on the original iTunes Library, and becuase of that it is also now enabled on your new computer.
This is changable in the Summary tab of iTunes when you have your device selected, and this article will help you do that:
Managing content manually on iPhone, iPad, and iPod
http://support.apple.com/kb/ht1535
Configure iPhone, iPad, or iPod for manual management
To manually manage the content, follow these instructions:
Connect the device to your computer.
Open iTunes.
Select your iPhone, iPad, or iPod. If your device isn't visible in the upper right corner of the screen, choose Library.
Click the Summary tab and select "Manually manage music and videos."
Click Apply.
Thank you for using Apple Support Communities.
Cheers,
Sterling
