ITunes 7.6.1 Library corruption & possible solution

For two or three days itunes have been crashing with -50 errors (cannot save the library file) just after trying to play a song after a fresh launch. Otherwise if quitting without playing any music, I would get a dialog upon normal quit which informed of unexpected quit and invalid disk access errors (multiple crash reports sent to apple over the past 48 hrs)
I have over 30,000 tracks and do not wish to rebuild/reimport/recreate the library again
Booting from Install disk and verify & repairing the disk with disk utility was successful (invalid free space corrected) but did not help with apparent itunes library corruption.
Deleting the various itunes related prefrences from user/lib/prefs and user/lib/prefs/byHost did not help. Reinstalling a fresh copy of itunes downloaded from apple did not help
Trying to rebuild the library created new a library that would still crash with -50 errors
(after taking something like an hour to create a fresh library with assosiated loss of perfectly good album art that was fine before the corruption started) Other weirdnesses included the name of my podcast download folders and my library name in itunes windows changing to japanese/korean/chinese
solution? Disable iwow, turn it off or uninstall it.

I've been unable to launch itunes (7.6.2) ever since the latest updates. Actually, I could launch in a library-less test account, and once after deleting my entire preference (although upon the next restart I had the same problem).
What is iwow?

  • UPK 3.6.1 Gkn.OnDemand.Library.OfflineException - Possible solution

    Hi all,
    Apology if this has been posted already, but I search Oracle articles/forums/support and various websites and couldn't find any solution until I just happen to stumble upon it by chance.
    I thought I'd try and share this solution in case someone else is having the same issue as me which took a couple of weeks to work out.
    A few weeks ago I got a request to setup Oracle UPK environment. Things went smoothly until it tries to populate the library.
    Platform: Windows 2008 R2 64bit

    The closest solution I could fine is:
    Gkn.Ondemand.Library.Offlineexception While Installing Upk Server [ID 785488.1]
    Which says to give full control access to everyone across the entire disk.
    Well it didn't help my issue. After searching various websites, it appears quite a number of people were experiencing the same issue, but no solution were posted or documented.
    Tested IIS and it showed it was working OK. Can see default page with big flashy IIS7 logo. Made sure oracle database and connections are ok.
    One guy from another forum said he had to resort back to installing it on Windows 2003 32 bit.
    Well I gave that a try, and still experiencing the same issue.
    For a full week I couldn't work out what's going on, until I tested IIS on the Windows 2003.
    The localhost default page was displaying access denied. Squid (Proxy server) was complaining about security issue.
    Then it hit me. This is an issue relating to the proxy server.
    My company have serveral proxy servers, therefore the server I was setting up UPK on, its Internet browser proxy setting was set to autodetect.
    After ensuring no proxy has been set and the autodetect option is not selected, UPK server installation ran without an issue.
    So if you have a similar issue as me give it a try.
    Sorry the post is quite long, but I wanted to give a good details on what the issue was and what worked for me.
    Hopefully I could save time or frustration for someone.
    Cheers.

    Proxy change did not help me. My error is below: Can you provide any help?

  • Itunes hangs when burning cd's - possible solutions

    Hello everyone,
    I've had what appears to be the same problem as many many more people on this site.
    I haven't got a complete fix, after 4 months of trying but I've got as far as I have with the help of Toonz and the people at Apple.
    Now here is what I have found:
    1. The problem with my Itunes hanging at burning only happens if I have a mixed playlist that I am trying to burn. When I say mixed I mean a mix of purchased tracks and uploaded tracks from my cd collection. Just uploaded tracks work fine.
    2. If I just burn a playlist of purchased tracks it works fine too.
    3. If I don't control alt delete when it hangs, and I wait for up to 2 minutes, the burn evenutally kicks in. Don't do anything. Just leave it and see what happens. I was having to control alt delete to get out of the unresponsive Itunes, but by chance, yesterday, discovered that by leaving it it finally burnt my cd! This was a mixed cd with both purchased tracks and uploaded tracks.
    Now, the people at Apple don't yet know why this is doing this. It only happens since version 6 of Itunes. This version (I think) was the first to introduce the "checkingplaylist" stage of burning and they seem to think that it might just be something to do with that.
    Anyway, that all helped me. It is still frustrating to have to wait for a couple of minutes, but it's better than nothing. They are still trying to get to the bottom of this for me, too.
    I hope this helps at least some of you.
    Please give me some feedback if it has, as I'd love to know that all my efforts over the last few months could help others!
    Good luck
    Jane

    I think I'm in love...
    I just spent the past 3 hours running through reinstalls of iTunes, looking at every support topic and finally found this wonderful, wonderful thread.
    I am having the same exact problem with mixed playlist burns.
    I also have great success with waiting for only about 1-2 minutes while iTunes shows "Not Responding". Then it fires right up and burns perfectly.
    Thank you for posting this quazi solution, and it has helped me tremendously. Well, at least it has saved me from having to transfer all of my music to a new digital music manager.
    I hope this issue gets resolved soon

    Just downloaded new verion of ITunes, now when I try to open ITunes get This copy is corrupted or is not installed correctly. Please reinstall ITunes. Running XP. I do not want to lose everything I already have on ITunes.Does anyone know what the solution might be?

    Hi, oldcrow13.
    Thank you for the response.  Typically this error is caused by installing an older verison of iTunes than you had prior.  When you installed iTunes did you download the program directly from iTunes.com, or did you use an older copy of the program on your computer?  If you used an older version or are unsure, uninstall all the components one more time and download a new copy of iTunes via the link below.

  • My iTunes says this copy is corrupted or not installed correctly and I should reinstall iTunes.  Will this wipe out my library

    When I hit my iTunes icon I get an error message that says "this copy is corrupted or not installed correctly. Please reinstall iTunes".
    So, my question is, if I reinstall iTunes will my music library be wiped out?

    Let's try a repair install of iTunes first.
    Restart the PC. If you're using Vista or 7, now head into your Uninstall a program control panel, select "iTunes" and then click "Repair". If you're using XP, head into your Add or Remove Programs control panel, select "iTunes", click "Change" and then click "Repair".
    Can you launch your iTunes now?

  • I have removed all music/movies/etc. from iTunes due to duplicates. I have connected iTunes to a NEW library only to have the same problem, duplicates (2 or 3 of every song). I need a solution.

    I have removed all music/movies/etc. from iTunes due to duplicates. I have connected iTunes to a NEW library (38.33 GB) only to have the same problem, duplicates (2 or 3 of every song or 63.80 GB). I did not have this problem until syncing my library with the new Macbook Pro. I need a solution (a solution IS NOT sifting through my iTunes song by song and deleting the duplicates).

    Try disabling the computer's antivirus and firewall.
    - Next try the manual install method of:
    iDevice Troubleshooting 101 :: iPhone, iPad, iPod touch
    Place the iPod in recovery mode after the firmware download is complete and then restore using the instructions in the article. Sometimes recovery mode timeouts and returns to disabled before the firmware download is complete.
    - Then try on another computer

  • ITunes Music Library corrupted by Update 5.0?

    Yesterday iTunes was normal. Late last night Software Update presented me with an update to iTunes (5.0) which I declined to install. This morning, when I launched iTunes several unexpected things happened:
    1. iTunes hung searching for (or loading) the Library for nearly 30 minutes. On launch I saw the loading progress bar, then was busy with other things (in other Spaces desktops) till I noticed it hung. I cancelled this loading operation and continued launching, then...
    2. iTunes reported a damaged Library which would be renamed "iTunes Library (Damaged)" and that a new library would be created.
    3. iTunes very quickly began rebuilding my music database, searching for album art, etc. -- all of which I stopped as quickly as possibly.
    4. iTunes launched with a completely bare browser (new installation: utterly without any of my stuff), which was a shock to say the least, but all the previous occurrences began to add up. I quit iTunes.
    5. I went directly to the Music/iTunes directory and began investigating. I found that...
    6. iTunes had created a brand new file named < iTunes Music Library.xml > at 12:53 PM (it's now 1:53 exactly) and a file named < iTunes Library (Damaged) >.
    7. Previous iTunes libraries I have collected over the years (by manual backup and in Time Machine) are named < iTunes Library.itl > (I assume ".itl" stands for iTunes Library).
    8. I went to System Preferences/Software Update/Installed Software and confirmed that the most recent software update was "Java for Mac OSX 10.6 Update 6 Version 6.0" on 11/11/11; as expected, I had NOT inadvertently installed the unwanted iTunes update last night.
    Before I begin bleating my own opinions, I would love to get more informed comments and answers to a few perhaps obvious questions.
    Q1. What happened?
    Q2. Could it have been related to the update I declined to install? (Pure coincidence would be positively mystical.)
    Q3. If not (Q2), then why the radical change in Library name and tag ( iTunes Library.itl --> iTunes Music Library.xml )?
    Q4. Can I use my manual backups (or Sync, or Time Machine) to restore the previous Library and get my hard-wrought, very coveted collections back as they were? If yes, how? If no, what then?
    I do not yet plan to update my Mac OS to Lion for a number of reasons (therefor making the Apple Cloud service unavailable to me), so I'd intended to be cautious about related updates, such as the updates to iTunes, iPhone (...) and wait a bit. The DotMac/MobileMe account I've had since the beta days will remain active till summer and I figured I'd have plenty of time to think about it and to formulate a strategy for dealing with dreaded software/hardware obsolescence issues and so on.
    Thanks to the community for any help forthcoming.

    Some clarifications (hopefully):
    The iTunes update flashed by me pretty fast on the night of Nov 15 as I quickly chose not to accept it. I seem to have mistaken the version number. The newest version of iTunes showing at the Apple site is 10.5.1 (I thought I'd seen a 5.0, but obviously not). I just looked in the Applications folder at the iTunes app version; it's 10.5, and the Date Modified is October 12, 2011. As mentioned above, System Preferences/Software Update/Installed Software shows no recent update to iTunes. It seems Software Update was trying to update iTunes to version 10.5.1 on the night of Nov 15th..
    Also, I spent a bit more time today trolling about some loosely related discussions on these lists, and believe I might have misunderstood the three types of file I mentioned, so I looked more closely at them:
    Music/iTunes Folder:
    < iTunes Music Library.xml > Shows created Aug 3, 2008, modified Nov 16 at 12:53 PM.
    < iTunes Library.itl > Shows created (12:52) and modified (12:53) yesterday (Nov 16.).
    < iTunes Library (Damaged) > Shows created Oct 12, 2011, modified Nov 15, 2011 at 7:55 PM (when update was cancelled).
    Applications Folder: iTunes (app) - version 10.5 - created Jan 14, 2008, modified Oct 12, 2011 (Finder info);
    System Preferences/Software Update/Installed Software: iTunes 10.5 installed Oct 12, 2011 (nothing more recent)
    Why was the "iTunes Library (Damaged)" file created a _month_ ago and only modified when I declined the iTunes 10.5.1 update? I can't get any sense from this. Now past 2 AM on the 17th. I'm calling it a day on this. Hope to get iTunes up and running soon.

  • ITunes 8 Causing Library Corruption

    Since installing iTunes 8 I've had some issues of library corruption such as a song suddenly being named under a different artist/album/track number etc. Only the bitrate seems to be accurate under these files. Was curious if anyone else had had issues with this at all.

    I am also getting corruptions. I usually keep iTunes open all the time since I stream my tunes to my AppleTV through my stereo. If I quit iTunes, it says saving iTunes Library and then quits. Then when I restart it starts and gives me a "Importing" message and then says my library is corrupted. I have to then reimport all 7000+ songs and iPhone apps. This is happening none stop and is very reproducible. This has only been happening with iTunes 8.

  • Possible Solution to Google Search Bar Not Working/Safari Not Loading Pages

    Hello Apple Forums,
    I have recently encountered a possible solution to a problem with Safari. The one in which Safari fails to load any page associated with www.google.com. Especially the Google Search Bar—a feature I use frequently.
    After browsing through the forums about the Google Search Bar issue, I took my knewly gained knowledge, and decided to do some diagnosing for myself.
    This is what I have done so far to try and solve this issue:
    Run Daily, Weekly, and Monthly Cron Scripts
    Cleared the following caches:
    System Local Computer Cache
    System VM (Swap) Files
    Curent User Cache
    Current User Icon Cache
    Internet Explorer Download Cache
    Page History
    Web Site Cache
    Temporary Files
    Safari Downloads List
    Form Values
    Page History
    Recent Searches
    Site Icons
    Web Site Cache
    User Cookies (used by Safari)
    Finder Recent Applications
    Recent Documents
    Recent Folders
    Recent Servers
    Recent Files of AppleWorks 6
    Disk Utility Disk Images
    Preview
    QuickTime Player Favorites/Recent
    REALbasic Projects
    TextEdit
    VideoLanClient
    and Other caches of Acquisition Current Downloads
    Acquisition Recent Searches
    MSN Conversation History
    Vicomsoft FTP Client Icon Cache
    All of the above runnings of Cron scripts and clearings of Caches were done using Mac Pilot version 1.1.5 (yes the one on the site is an updated version, but I have not downloaded it yet). If you decide to use this program to clear caches, I advise not clearing the Installer Receipts under the System section as Installer Receipts are used to correctly repair permissions. I do not clear Find File Indexes either, because I use the Find File feature quite frequently on my computer and I do not want to have it re-index files all the time (perhaps I'll do it every few months or so to refresh what I've got on the harddrive). Remember, all the information given in this paragraph is relative to Mac Pilot version 1.1.5.
    In addition, I have also repaired permissions using Disk Utility 10.4.4 (v145.7) (make sure you restart your computer after you repair permissions). I have taken out items in /harddrive/library/StartUpItems as well as taking out items in /harddrive/library/Internet Plug-Ins and in /user/library/Internet Plug-Ins and in user/library/Caches (restart your computer after taking out or putting in items in these locations).
    As of now, all the information mentioned above about trying to fix this problem have NOT worked.
    What HAS WORKED for me was tinkering with my 3rd party firewall—Norton Personal Firewall Version 3.0 (48). Under the Protection Settings, I HAD Enable Active FTB support, Enable Stealth mode, Enable suspicious activity protection (with Deny outgoing suspicious traffic and Deny incoming suspicious traffic selected), Enable UDP Protection (with Protect outgoing UDP connections, Allow access to essential services, and Protect a range of UDP ports 1 through 1023 selected).
    What I CHANGED in Protection Settings was DESELECT Enable suspicious activity protection (with Deny outgoing suspicious traffic and Deny incoming suspicious traffic DESELECTED). Upon deselecting that information the Google Search Bar feature in Safari WORKED practically instantaneously. Before hand, anything I inputted into Safari and after hitting Return on the keyboard just wound up hanging there.
    Just to be sure, all tests were performed on:
    IMac G4 800 Mhz SD Mac OSX 10.3.9 with ALL the latest Software Updates, Except Apple Remote Desktop Client version 1.2.4 and iPod Updater 2006-01-10
    I have a cable internet connection with ISP Time Warner Cable (RoadRunner) using a SurfBoard SB4100 Cable Modem on an AirPort Extreme Base Station (Apple Base Station V5.6)
    Interesting side note: I have a PowerBook G4 15" 1 Ghz Mac OSX 10.3.9 Laptop running on the same network (although it has an airport extreme card as opposed to the regular airport card in the iMac) with ALL the same latest Software Updates, Except iPod Updater 2006-01-10. The Apple Remote Desktop Client version 1.2.4 does not come up on Software Update on the Laptop and I can not find it on the harddrive using a name search in the Finder Find feature. It does not show up in Applications folder, so I do not know if it is on or active on the Laptop.
    The LAPTOP IS ABLE TO USE ALL GOOGLE FEATURES without DESELECTING Enable suspicious activity protection (with Deny outgoing suspicious traffic and Deny incoming suspicious traffic DESELECTED). Why this is apparent I have not officially confirmed.
    What I do know is that I have tried to Uninstall Norton Personal Firewall Version 3.0 (48) with the appropriate uninstaller but it FAILS during the uninstall (I wanted to uninstall and reinstall, it appears the program became corrupted). What I did to possibly circumvent this was to search for the phrase 'Personal Fire" using the Finder's Find feature (Search for items whose name contains 'Personal Fire') and deleted all the files that came up related to Norton Personal Firewall Version 3.0 (48). I then reinstalled Norton Personal Firewall Version 3.0 (48) since then, and it continues to have the problem with Enable suspicious activity protection (with Deny outgoing suspicious traffic and Deny incoming suspicious traffic selected).
    What I have not done:
    Updated Prebinding
    Run TechTool Pro version 4.1.2
    Install Combo OSX 10.3.9
    Initialize HardDrive with complete reinstallation of OSX 10.3.9
    To Summarize Possible Solution
    I've tried many possible solutions, what appears to work best as of now is to DESELECT Enable suspicious activity protection (making sure Deny outgoing suspicious traffic and Deny incoming suspicious traffic are deselected) under Protection Settings in Norton Personal Firewall Version 3.0 (48).
    One could try deselecting something similar in any firewall application other than Norton Personal Firewall Version 3.0 (48), to see if it is suspicious activity settings in firewalls that cause the problem.
    Any comments/feedbacks are extremely welcome.
    Hope It Helps!

    Hello tr:
    Welcome to Apple discussions and thank you for your very very thorough post.
    Your instincts to delete anything named "Norton" were right on the mark. Norton software is POISON to Macs running OS X. An additional software firewall is, IMHO, completely unnecessary. Turn on the built-in firewall in OS X - it is robust. In fact, if it is already on, there may be a conflict.
    Go to Symantec's web site and use the uninstaller you should find there to get rid of the Norton stuff. After you do that, do a "find" on Norton and Symantec to be sure it is all gone - the stuff hides everywhere.

  • How 2 sync 2 iPhones on 2 computers with two iTunes accounts and 1 library?

    Hi,
    I've been searching a LOT for a suitable answer to my problem, but so far without any luck!
    This is what I've got:
    1 iPhone4 syncing with one MacBook via iTunes account1 (mine)
    1 iPhone3Gs syncing with one XP laptop via iTunes account2 (my girlfriend's)
    1TB usb drive connected to Airport Extreme holding the entire iTunes library. All the music, apps, podcasts, etc.
    Both iTunes accounts are set up so they point to the 1TB drive, but it's not without problems...
    What I'd like, is for both computers to be able to "see" the iTunes library, and add files to it, that'll be accessible from each.
    And still sync each iPhone with it's own iTunes account.
    Is this possible? Or do I need to use the same iTunes account on all phones and computers?
    What I've got, apparently, is home-sharing set up in a way that when I add content from iTunes Account1 to iTunes Account2, it gets added to the iTunes library again, and so I have a lot of doubles and, despite the size of the network drive, I'm actually running out of space.
    Is there a way to avoid this?
    Best regards,
    Jakob Færch-Jensen

    First off all I would recommend against shating between accounts since Aperture was not designed for this and your might encounter library corruption.
    You might try this tip on Macworld.com. It requires you to use the Terminal though. Make sure you follow the commands exactly, without any typo's before you hit the enter key to execute a command. (And make a TimeMachine backup before you start.)
    After you've complete this, start a new library in the place where you set the extended permissions on. Then everything should work.
    A seccond tip is to setup the Aperture library on an external drive and set this volume(drive) to ignore ownership permissions.

  • Why is iTunes saying my iPod is corrupted and how do I fix it?

    I got a new computer for work, downloaded iTunes and connected my iPod classic (20GB). I added a few songs to my library before I connected the iPod. Once connected, my iPod appeared but after trying to transfer music an error occured. iTunes stated my iPod was corrupted and it asked if I wanted to reset it, which would wipe my iPod clean.
    I checked my Ipod's functionality and it was working fine. I tried connecting it to a couple other computers I use and it still worked fine. In the meantime, I uninstalled all of the iTunes programs and reinstalled everything. I connected the iPod again and the same problem occured.
    I do not think I transferred any corrupted songs onto my iPod; it has been working fine. I really do not want to erase my iPod and start from scratch unless that is the only solution. I am just not sure why my iPod is not working with this specific computer...it is brand new! When I connect the iPod now, it appears sometimes but it always ends the same. The computer also asks if I want to scan the E drive (the drive the iPod is connected to).
    Thoughts?

    +The computer also asks if I want to scan the E drive (the drive the iPod is connected to).+
    That it almost surely due to some security software/antivirus stuff that was installed by corporate.
    Ask your IT folks about getting itunes running on this PC and make sure it's allowed by your company.

  • My itunes recently lost its library for no apparent reason.

    My itunes recently lost its library for no apparent reason. The only library backup is an old one that does not reflect my current iPhone, and I do not want to have to re-input all the lyrics for the music I have imported in that time. Does itunes not automatically create a backup of its libraries? Is there anyway to copy this information off the iPhone?
    I'm okay to simply drag all my music into a new itunes library, I don't want to go through the process of editing each individual file again, whether its cutting certain start/stop times, or inputting the lyrics for every single song...
    Any ideas? I've tried googling a solution for hours. I even tried to system restore. This morning when opening Itunes, it simply told me that it could not locate a library, please select a library.

    Empty/corrupt library after upgrade/crash
    Hopefully it's not been too long since you last upgraded iTunes, in fact if you get an empty/incomplete library immediately after upgrading then with the following steps you shouldn't lose a thing or need to do any further housekeeping. In the Previous iTunes Libraries folder should be a number of dated iTunes Library files. Take the most recent of these and copy it into the iTunes folder. Rename iTunes Library.itl as iTunes Library (Corrupt).itl and then rename the restored file as iTunes Library.itl. Start iTunes. Should all be good, bar any recent additions to or deletions from your library.
    See iTunes Folder Watch for a tool to catch up with any changes since the backup file was created.
    When you get it all working make a backup!
    Should you be in the unfortunate position where you are no longer able to access your original library, or a backup of it, then see Recover your iTunes library from your iPod or iOS device.

  • Problems with new library - old library corrupt.

    Right. Here's the story.
    My iTunes library corrupted (this has happened a few times) so the only solution I saw was to create a new library.
    I don't mind having to create new playlists etc and sync new music, but the problem is with my iPhone:
    When I try to sync, it syncs contacts and calendars etc but it says that it is synced to a different library so I should erase and sync when I try to update music. So I do this, but because I don't want to lose texts messages and notes stored on my iPhone I restore it from the backup. But then the back up seems to store information as to which library it is synced with and so it says I have to erase and sync again.
    So, the question is, is there anyway of syncing my iPhone with a new library but retaining all the data that is not normally synced with iTunes (notes, text messages etc) ?
    Thanks for your help.

    I don't have an iphone - you might have some luck asking over in the iphone forums.
    However, I notice you've a Vaio. If you read , and disable that sony program named VCFw.exe, it may solve the root problem of your itunes library getting corrupted.
