Out of the blue Itunes can't find a large qty of songs, with a twist

The library has been in tact and functional for some time now until today. Itunes has lost location of a  large quantity of songs in my library. I have gone through the song location process at which point itunes asks whether it should locate all of the missing files in the same location. My understanding is that when you click yes it should look for the missing files in the proper directory and make the connection. What happens for me is that I get  the dreaded pinwheel and itunes freezes. I don't know whether this has to do with the latest itunes update, which I believe happened within the past week. At any rate, does anyone have any ideas about what the problem might be and how I can ultimately find all of the missing songs without a system freeze and without having to do them individually?
imac 2.8 GHz Intel Core i5

library located on an external drive.
On a force quit here is the report data. apologies for its length.
Thank you in advance for your help,
Peter

iOS: Device not recognized in iTunes for Mac OS X
Or
See
iOS: Device not recognized in iTunes for Windows
- I would start with
Removing and Reinstalling iTunes, QuickTime, and other software components for Windows XP
or                     
Removing and reinstalling iTunes and other software components for Windows Vista, Windows 7, or Windows 8
However, after your remove the Apple software components also remove the iCloud Control Panel via Windows Programs and Features app in the Window Control Panel. Then reinstall all the Apple software components
- Then do the other actions of:

paying special attention to item #5
- New cable and different USB port
- Run this and see if the results help with determine the cause

  • HT5100 iTunes can't find a link for a song I purchased

    iTunes can't find a link for a song I purchased last month. How do I re-download my song? iCloud doesn't allow me to re-download it, so I'm at a loss...

    You would need to contact Apple Support to have your Security Questions reset:

  • Running 10.9.2, out of the blue I can no longer minimize e-mails in Mac mail program.  I have to put the cursor on the upper edge of the screen to show the tool bar that allows me to scroll down to quit mail to get out the of the program.

    Recently my mail program has changed itself and I can no longer see the red, yellow and green dots allowing me to close minimize and enlarge.  To get out of mail I have to put the cursor on the top edge of the toolbar expanding to another toolbar that will allow me to quit mail.  This is a real pain right where my mother never kissed me.  How do I get the dots back?

    Move the mouse to the far upper right corner of the screen.  You should see a blue box with two arrows pointing inwards.  Click that blue icon.  Sounds like you put the Application into whats called Fullscreen Mode.

  • I just got a "runtime error" out of the blue, itunes wont open

    i just got a "runtime error" and itunes will not open, never had this happen before. another screen said itunes not installed correctly, reinstall it but i dont wanna loose all i have if i reinstall... help please

    Under normal circumstances, an uninstall/reinstall doesn't touch your content. (That being said, it's still always a good idea to maintain a current backup at all times in case of disasters of any sort.)
    First try updating to iTunes 11.1.5.5, using an installer downloaded from the Apple website:
    http://www.apple.com/itunes/download/
    If you still get the errors after that, try the following user tip:
    Troubleshooting issues with iTunes for Windows updates

  • Out of the blue, ITunes 11 on my MacBook Pro doesn't recognize either my iPad 2 or my iPod touch.

    I use the USB cable to sync both with iTunes on my MacBook Pro and it worked fine until a few days ago.  I tried both USB ports on the MacBook and 3 different 30 pin to USB cables, and they will charge both devices, but neither one shows up on the iTunes toolbar as a recognized device.  Help!

    Templeton's the Man.
    Word of warning to save you from surprises. The 13" MBPs have Shared Video Memory. This means that the main memory is used both for holding all the programs you are running at any given time, the files those programs may be working on, AND the space needed for storing all that's being displayed on the screen. Plus, the Core i5 processor and the graphics processor have to take turns at getting to all that information. This means that although games will run on that computer, if they are very graphics intensive, performance may be less than expected. Because of this and since you are using Lion 10.7.3, it may be advantageous to upgrade the memory to 8GB.

  • Itunes can't find original file for many songs

    Something has happened, either you have moved the songs, changed the drive letter there on OR antivirus is "Playing around" with iTunes.
    If you have moved the files, put them back EXACTLY like they were, If these songs are on an external drive, make sure windows did not change the drive letter.
    Also try scanning the system with antivirus AND a malware scanner that scans for ad ware and spyware

  • ITunes can't find artists beginning with THE

    My music collection was getting too large for my internal hard drive so I changed the location of my iTunes folder to my external drive, where there was already a back up of all my music. This I create by directly copying the itunes music folder every so often. Keep itunes organised is checked. When I changed the folder location, it did updating library, then asked if I wanted to organise the folder which I did.
    However now, it won't find certain tracks/albums, says the orignal file location cannot be found do I want to locate...
    It appears that itunes can't find any track whose artist begins with the word THE, although they are in folders called "The...." in the correct music folder.
    I just updated to the latest version of itunes.
    Does anyone know what might be going on???

    Something similar happened to me. iTunes could not find any music that had the track number at the beginning of the name (an option in Advanced->Import section). My purchased music also had track numbers, but I don't know if Apple did that, or if my own iTunes did it.
    At some point, I had turned off this option, so all the songs I imported after that were found just fine. When I deleted the track numbers from the file names, iTunes found them just fine. I have way too many files to change all the name manually however. Changing the naming option in the iTunes preferences did not make a difference to the problem.

  • I moved all my music from c: drive(because it was full) to an external harddrive and now itunes can't find any of my music. Is there a way to get Itunes to find music on external drive without having to place all the music back onto the c: drive? Thanks

    Hopefully you moved the entire iTunes Media (or iTunes Music) folder to a new path on your external drive. Copy your iTunes library folder out to the root of the external drive, e.g. X:\iTunes (where X: is your external drive), then move the media folder inside it. Hold down shift as you start iTUnes and keep holding untila asked to choose or create a library. Choose the library at X:\iTunes\iTunes Library.itl. Should all be good.
    Failing that, download and run my FindTracks script and point it at the new location of your media folder.

  • ITunes can't find the original file?

    I have my entire iTunes collection on my iPod and, supposedly on my laptop. Yet every time I click on a laptop song, I get a message telling me that ITunes can't find the original song, do I want to look for it? I then have to run "Search", wait for the song to appear, and click on it to add it to my usable library. Then, I get two listings for the same song, and if I eliminate one listing, I get the "can't find original" message again. I have just under 60 gig of music and I don't want to search and add thousands of songs when they are already in there somewhere. I appreciate greatly any one's expertise in helping me solve this frustrating problem. Thanks!

    Hi, Mike-D.
    I'm assuming your music files are all in one centeral location - the iTunes Music folder or what have you.
    There are a few basic strategies for dealing with your unfortunate situation:
    1) Telling iTunes where the lost songs are on a one by one basis.
    2) Moving the songs to where iTunes thinks they are. Unfortunately, there's no way to find out where that might be.
    3) Start with a new iTunes library. Regrettably, this method will lose your playlists and related information (Ratings, Play Counts, Dates Last Played, etc.).
    If that's not a deal-breaker for you, delete the current entries in your Library by highlighting them - iTunes Edit menu > Select All - and then right-clicking > Delete . You remove the entries from your Library but keep the files themselves in your iTunes Music folder, again that's assuming that's where they are in the first place.
    You can then add them back into your Library by selecting the iTunes Music folder in Windows Explorer and dragging it into the Library entry in the iTunes Source List (left-hand column).

  • Upon start up of my laptop I get a APS Daemon.exe system error - MSVCR80.dll is missing.  This just started out of the blue.  At one point it told me to reinstall ITunes.  Is that truly necessary?

    I have the same issue after installing the new update and reinstalling iTunes doesn't fix the issue.
    I found disabling Apple push (APSDaemon.exe) from the start up will stop the error from appearing, however this will disable wireless syncing. If you don't use it than it shouldn't be an issue.
    I'm using a PC so you can disable it using the msconfig command and turning it off in the Startup tab. I don't know if Mac users are experiencing the same issue. Hopefully Apple will fix it in their next update.

    Download the Windows Installer CleanUp utility from the following page (use one of the links under the thingy on the Major Geeks page):
    http://majorgeeks.com/download.php?det=4459
    To install the utility, doubleclick the msicuu2.exe file you downloaded.
    Now run the utility ("Start > All Programs > Windows Install Clean Up"). In the list of programs that appears in CleanUp, select any iTunes entries and click "Remove", as per the following screenshot:
    Quit out of CleanUp, restart the PC and try another iTunes install. Does it go through properly this time?

    Hi ChrisBell,
    my Pixi shows me the missed calls in a list of its own? I don't have many, so maybe I'm missing something. But I agree with your half-ranting to some degree. As a long-time Palm-user (my last phone was a Treo 680, terrible form factor, good UI), I am really disappointed with the standard software on this phone. Memos and Tasks, which AFAIK were there and useful even on the first Newton's, have regressed beyond the point of usefulness now (solution: Toodledo and Done!, at least for now).
    But ChrisBell: if you feel up for it, you could start tinkering. Many people love these phones so much they have started developing patches to solve the obvious problems skimmed over by developers. Try looking up "webosquickinstall" and "preware", and you will find over 300 patches and a lot of free software to help you out. I am not a computer wizard myself, but I am not scared of them either, and I have been able to make good use of all these extras made available by the community.
    just a thought, might help you out on a few of your half-rants

    Don't you just love changes in interfaces?
    I found the answer to my question.
    When you attach a device (iPhone, iPad) to your Mac, in iTunes 12 in appears as a tiny icon in the second "row" of the iTunes display. Click the icon and the familiar iTunes display for the device appears. From there, on the Summary screen, you can see the dates of the backups of the device (iCloud and backup to the computer). You can also use the button to backup to the computer.

  • Move all my music to another folder but Itunes can't find the files!

    I have all my music on my desktop in small folders for each artist.
    But now i don't have room anymore, because i have to much music.
    So i want to move it all in to a folder called "Music". But when i do that
    Itunes can't find the files, and i have to search for each file, to find the new location instead of the desktop. How do i move my music more easily? So i don't have to synchronize it all in again, with the right album covers and that..
    Please, need some help here!

    You need to open your preferences file in iTunes and click on advance then select the location of where you put the folder.  http://support.apple.com/kb/HT4527
