I want to sync the songs on my Mac to my iPod, but it says, 'An iPod can only be synced to one iTunes Library at a time. Erasing and syncing replaces the contents of this iTunes Library.' Will this reset my iPod completely (my iPod is 4th gen)?

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.

  • 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:

  • 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.

  • IPhone synced with another library..."Erase and Sync" question

    I helped someone transfer from an older iPhone to an iPhone 6 and did an encrypted backup on my laptop and then restored that backup to their new phone.
    When they took the phone home and tried to sync their library with it they got the following message:
    "The iPhone ... is synced with another iTunes library on ...  Do you want to erase this iPhone and sync with this iTunes library?"
    I understand what iTunes is referring to but what does "Erase and Sync" actually do?  Does it just erase any media i.e., songs, apps and videos and then resyncs them from the new library or does it completely wipe the phone and start from scratch?
    Thanks...

    When you say erased, you mean almost like a restore is done to factory settings instead of just the media being erased?
    I ask because the older phone is no longer available and they want to preserve their photos, etc.
    Can I backup the phone on their computer, select erase and sync and then restore from that backup?

  • How to make 1D Array but with only one element filled in Real Time

    Hi folks,
    here I am with another question. I want to implement an prediction discrete state space observer which is going to run on a CRIO real time target. I am going to do it just like in the example which comes with LV.
    I have some questions regarding the input and outputs which in the example those are "dummy".
    My model is a SISO model, but the function "Construct SS model" returns parameters (A,B,C,D Matrices) as 2D arrays, so once you connect the cluster model into the Discrete Observer model, it takes y and u as 1D arrays despite of the fact that there is a SISO model.
    I realized that the function I am using in the simulations, uses 1D arrays but with only one element filled:
    Does anyone knows how to implement such 1D arrays in Real Time? I guess the way to do it is preallocating one array of zeros of size 1, and then recirculating it through some SR, and replacing the element with my real input and output, but at the dummy.vi, they are using a simple "build array"
    function.

    Ok, I did it that way. But I am facing another problem right now...
    At some point the Discrete Observer return a NAN array, you will see the code in the code snippet?
    I get rid of that component by component, but the observer gets "stuck" in it. So my Control law is zero... but the state stimate is NAN.
    Also I am attaching the VI.
    I do not know why, since in the simulation program all runs well. any thoughts? Maybe the internal numeric precision of the State Space Model?

  • I can't get my ipod to sync with new laptop. I have tried to erase and sync, I have authorized new laptop, and still can't get new songs on ipod. Help

    I had to purchase a new laptop, since my old one crased. I downloaded iTunes, and my library came up. I followed the directions given, synced ipod, authorized computer and was given a pop up that stated 25 of my songs could not be transferred.Go to Store, authorize computer and resync. Which I did. When I authorize computer another pop up appears and it states this computer is already authorized. I am getting really frustrated. I have gone to the Apple store several times, had to make appointments as they were to busy to help me then. I show up for appointments to either be told, no appointment appears in their schedule, or they are running over an hour late. Any help would be greatly appreciated!  Thanks

    Why can't the songs be transferred to the device?  Is it because they are not authorized?  Were these 25 tracks purchased/downloaded with the same account you have used to authorize the PC/new iTunes library?
    Have you seen this article yet?

  • Every time i plug my iphone into computer it wants to erase and sync

    iphone was originally linked to my laptop... however i never transferred anything from the laptop to the iphone.  i now want to use my desktop to transfer music.  so i plug in the iphone, click the checkmark next to sync music. it says that the iphone is currently synced to another library and do i want to erase and sync?  so i erase and sync and pick the music i want and transfer it to my phone.  I unplug the phone, plug it back in again. in itunes it shows the music sync as unchecked... so i click the box to sync music and it says its associated with another library and it needs to erase and sync.
    i have done this 4 times now. and everytime it wants me to erase and sync even though i just did it on the same computer with the same i phone 3 times in a row.  i don't get it, why won't itunes/iphone sync with the new itunes library on my desktop??? what can i do to fix this issue?
    i'm using newest itunes 11 on windows 8.1 computer.  the computer has not been authorized... does this make a difference as to why the sync won't stick?
    BTW i also hate how apple makes you sync your phone, android is so much easier to just plug the phone in and transfer your music/videos manually.  never have a problem doing that.  Only when apple tries to make it so easy it gets way more complicated than it needs to be!

    Hi joy145,
    If you are having issues syncing and would like to manually manage your content, you may find the following article helpful:
    Apple Support: Managing content manually on iPhone, iPad, and iPod
    http://support.apple.com/kb/HT1535
    If you are still having issues or continually prompted to erase and sync, you may want to try restoring your iPhone to factory settings before moving your data over (either via syncing or manually):

  • Restored mac - iphone doenst recognize itunes - erase and sync

    HI,
    I recently had to completely restore my Mac Book Pro... complete re-install everything, OSX Mavericks, itunes, the whole 9 yards. Problem - My iphone was synced with the same computer, but now it doesnt recognize it as its "home" itunes library. So when i connect the iphone, it says the iphone is synced with another library and for me to sync it with this "new" library, i need to erase and sync, which of course i do not want to do.
    Basically i just got a new iphone 6, and was able to back up my 5s and restore it on the 6, but 2 things didnt come along in the restore, videos, and ring tones. That is when i tried to to sync the videos and ring tones thru itunes, i came across this problem.
    any solutions?
    thanks

  • Multiple events per date with only one photo each - Unwanted

    I have the eyefi wireless sd card in my camera and it is setup to transmit my photos into iphoto automatically, which it does. However, the problem arises in that iphoto creates multiple events for the same date each containing only one photo. I would prefer that iphoto create individual events per date and have the multiples of that date's photos within. I thought I had the settings configured to do so as I have preferences set for autosplit events one per day but I still see events such as - July 3, 2008 - July 3, 2008 - July 3, 2008 - each with only one photo inside.
    I am wondering if it is something in iphoto's settings or the way in which eyefi transmits the photos into iphoto.
    Any thoughts?

    I do not have a WiFi connection to my camera so can not test but am just guessing
    I can think of two possibilities
    - 1 - if you are taking the photos with the WiFi connected then each time you snap a photo it may be being sent which would be looked at as a new import and therefore create a new event - to stop this I believe you would have to not have a full time WiFi connection to your camera or somehow set the camera to send batched - not each one - iPhoto will take each batch into and follow the rules for making events for that batch even if you camera is sending many batches of One photo
    - 2 - You have the preference for making batches set to one every two hours and there is a long time between photos - I'm guessing that #1 is more likely

  • Itunes tells me to erase and sync

    Itunes is telling me to erase and sync to my current itunes library but everytime i try to click the erase and sync button it doesnt do anything.

    Place the iOS device in Recovery Mode and then connect to your computer and restore via iTunes. The iPod will be erased.
    If recovery mode does not work try DFU mode.

  • HT1202 I get how you can transfer purchases from a device to computer but what about the hundreds of songs on my iPad that were from CDs and non purchased? How can you move them from iPAd to computer if it wants to erase and sync?

    I am needing to transfer ALL content, not just purchased, to new computer and it wants to erase and sync because device is associated with another Library. Please help!

    What was the source to get that content onto the iPad?
    There has to be a middleman to get from CD to iPad - use
    backup of that to get content to new computer.
