Library Corrupt on External RAID

I have a Drobo external RAID that I store my iTunes Library on so I have data redundancy.  The library is VERY large with 393 movies and 687 albums.  I notice the about once a week the library file becomes corrupt and iTunes rebuilds it from the XML file.  This is annoying as it misclassifies Music Videos and Movies and loses some artwork.
I've noticed that the problem occurs after iTunes is not running and the RAID is in sleep mode.  Is this a known issue when the iTunes library is on an external disk that goes to sleep mode?
I disabled Sleep in Energy Savings settings, but I'd rather save the energy to be honest!

In a way you're pulling the plug on the external when the library file is still open which is a good way to corrupt any file, especially if iTunes is actually writing to it at the time (which it does constantly when it is open).  Maybe there's some fancy UNIX programming way of doing it but I can't help you with that at all.  You basically have to make sure the drives do not go to sleep when iTunes is running.

  • Aperture Library corrupted

    I have my 2007-08 Aperture Library on a external drive (2nd gen DROBO) with essentially all of my pictures as referenced files. A couple of days ago, I got a warning that said there was an inconsistency in the library and that I should do a consistency check. I did that, and after about 2 hours of VACUUM everything seemed to come back and was working fine. Yesterday, after exporting 600 images in three file formats to the Drobo, I got another inconsistency warning. I have started aperture with the command-option key down again and it still running VACUUM. Using Activity Monitor, Aperture seems to be doing something with Mach Messages Out, Mach System Calls, and Context Switches changing..going up.
    QUESTION: Is Aperture hung and not really do anything or is it still working away at a very nasty database corruption?
    If I get my database back, I will move it off the Drobo as I suspect (no proof) that there is something strange going on between their RAID structure and the continual updating of Aperture Library.

    OK...this is a remarkable story and I post it in case anyone else does a search on VACUUM, the software that seems to run when one does a consistency check.
    So I let the consistency check run overnight (CPU time was 13 hrs in Activity Monitor, but total elapsed time was about 24 hours. It was still running this morning so I decided to do a forced quit. Opened the Library on the Drobo drive and much to my amazement, it opened without difficulty and all the pictures were visible and it seemed fine.
    Having been spooked about what was happening to the AP Library (size 60 GB) on the Drobo when I exported files, under the Finder did a drag and drop of the Library over to my internal drive. Opened the Library on my internal drive and it successfully found all of my referenced pictures on the Drobo and seemed to function fine. Checked several of the projects and the few seemed ok.
    Have now done a SuperDuper backup of my internal drive to an external FW drive (part of the routine)
    Don't know whether the next time I do a large export to the Drobo whether I will have problems again with the Library, but I will provide an update to these notes in the future.

  • Issues with using my iPhoto library on my external hard drive.  Very slow to open and pictures disappear in thumbnail view.

    I have recently transferred my iPhoto Library to my external hard drive (WD MyBook Live) and have some questions.  Since I have done this and used the "alt + option" to select it as my default library I have been having some issues.  When using the library on the external drive as my default drive it takes a very long time to load compared to when it was on my macbook's hard drive. Is this normal?  Also, once it does load the thumbnails are only viewable when scrolling quickly through the photos and they are very blurry.  However, if I were to select one randomly (because of this problem I have no way of knowing which one I'm selecting) it brings it up in the edit view and it is a crystal clear picture.
    Is there a way to fix these issues?  I'd love to be able to use the iPhoto Library off the external drive to free up space on my macbook but if it isn't going to work as streamlined as it would on my macbook hard drive.  I have not yet deleted the original iPhoto Library from my macbook because I did not want to do so until I knew the new iPhoto library on the external drive was working properly.  Does this make a difference?
    Please help!

    The problem lies with occasional dropouts that can corrupt the library's database files if they are being written to as the time of dropout.  It's the nature of wireless networks.  If you have a very strong signal throughout and are willing to take a chance then go for it.
    But as for the speed, it must be iPhoto 11 and it's complexity causing the slowness. I had tried using a library on an EHD connected to my iMac from my laptop wirelessly with iPhoto 7 or 8 and it was pretty fast.  I think it was 7 before faces and places came into being.
    Send a feature request to Apple via http://www.apple.com/feedback/iphoto.html to improve wireless performance, etc.

  • I was trying to move iphoto library to my external hardrive, realised it was incompatible with Mac.  The iphoto will not open now, message is "Iphoto library is either in use by another application or has become unreadable".  I have read other posts.

    Hi,
    I was trying to save a copy of my iphoto library by copying images to my external harddrive.  I wasn't sure how to do it, realised the hard drive is not compatible. Now the iphoto library wont open and reads "iphoto library is either in use by another application or has become unreadable".
    I have tried to use options command and click on iphoto then rebuild yet nothing happens and same error message occurs.
    I have gone to  my personal drive, desktop, iphoto library, and found file Albumdata.xml and when i click on it, there is a lot of text in it, i am assuming these are all my photos.
    I have tried clicking and dragging this file to iphoto app and it doesn't work, as the same error comes up in iphoto being in use or unreadable....
    What am I meant to do with albumdata.xml file and how do I reopen Iphoto from here on in?
    Please help as I am not technically minded and still trying to understand how to use the Macbook at all as I am used to Microsoft.
    Thank you very much,
    KS

    Rule Number One - NEVER go directly uinto the iPhoto library - there are no user servicable parts in it and making any change no matter how small can corrupt your library and cause data or photo loss
    Exactly how were you trying to save a copy of your iPhoto library?
    Albumdata.xml does not contain your photos - and again NEVER make any changes to the content of the iPhoto library - no dragging - no changes - never go into the library
    We need to know exactly what you did
    And probalby the easiest solution is to load your backup from before you messed things up
    For reference after you get things working
    Moving the iPhoto library is safe and simple - quit iPhoto and drag the iPhoto library intact as a single entity to the external drive - depress the option key and launch iPhoto using the "select library" option to point to the new location on the external drive - fully test it and then trash the old library on the internal drive (test one more time prior to emptying the trash)
    And be sure that the External drive is formatted Mac OS extended (journaled) (iPhoto does not work with drives with other formats) and that it is always available prior to launching iPhoto
    And backup soon and often - having your iPhoto library on an external drive is not a backup and if you are using Time Machine you need to check and be sure that TM is backing up your external drive

  • HT1229 Tried moving my library to an external hard drive and now when I open iPhoto, there are no pictures there!!!!

    I am using iPhoto '08 and moved my library to my external hard drive exactly as all the instructions online explained how to do.  I renamed the original "iPhoto Library.old" and ,y external hard drive shows a iPhoto library using the same amount of memory as what it shows on my internal hard drive.  Here is where is becomes a problem.  When I hold the option key and open iPhoto, the only box that comes up does not give me a list of libraries to choose from.  It give me the option to "Create new library" or "choose existing library". When I click "choose existing library" I can find the copied library on my external hard drive but when I open it, iPhoto shows No Photos.  When I have tried opening the original iPhoto Library (the exact same way using the option key and choosing library) that I have not done anything to, except rename it, it does the exact same thing: No Photos.  Both my internal and external hard drives show about 137 GB of space being taken up by photos but I can't access them.  My other big problem is that ,y internal hard drive is completely full, which is why I am trying to transfer them to an external, to free up space so I am very limited on what I can do because I have no free space.  Also, when I open iPhoto and try to go to the Preferences to change to path under advanced settings, it freezes and I have to force close it. 
    Ay advice would be greatly appreciated as I am getting stressed out that I can't open my thousands of photos!

    My guess is that the library has been corrupted from being run on an overfull HD.
    So, try rebuild the Library on the External
    Try these in order - from best option on down...
    1. Do you have an up-to-date back up? If so, try copy the library6.iphoto file from the back up to the iPhoto Library (Right Click -> Show Package Contents) allowing it to overwrite the damaged file.
    2. Download iPhoto Library Manager and use its rebuild function. (In Library Manager it's the FIle -> Rebuild command)
    This will create an entirely new library. It will then copy (or try to) your photos and all the associated metadata and versions to this new Library, and arrange it as close as it can to what you had in the damaged Library. It does this based on information it finds in the iPhoto sharing mechanism - but that means that things not shared won't be there, so no slideshows, books or calendars, for instance - but it should get all your events, albums and keywords, faces and places back.
    Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one. 
    3. If neither of these work then you'll need to create and populate a new library.
    To create and populate a new *iPhoto 08* library:
    Note this will give you a working library with the same Events and pictures as before, however, you will lose your albums, keywords, modified versions, books, calendars etc.
    In the iPhoto Preferences -> Events Uncheck the box at 'Imported Items from the Finder'
    Move the iPhoto Library to the desktop
    Launch iPhoto. It will ask if you wish to create a new Library. Say Yes.
    Go into the iPhoto Library (Right Click -> Show Package Contents) on your desktop and find the Originals folder. From the Originals folder drag the individual Event Folders to the iPhoto Window and it will recreate them in the new library.
    When you're sure all is well you can delete the iPhoto Library on your desktop.
    In the future, in addition to your usual back up routine, you might like to make a copy of the library6.iPhoto file whenever you have made changes to the library as protection against database corruption. 

  • How do I move my iTunes library to an external harddrive?

    I recently purchased a new MacBook Pro and want to reload by CD collection into iTunes on an external drive.  In the past, I had been using iTunes for PC and the library became corrupted.  I would prefer to save the music to an external harddrive to save space on my MacBook's harddrive.  Once I load the music onto the harddrive, I want to be sure that my MacBook recognizes the library in the future.

    Creating a new library on the external drive will add to confusion because now you will have multiple iTunes libraries.  For simplicity it would be best to move your entire iTunes library to the external drive, unless you have a very good reason for wanting to split media storage locations.  To move a library if you use iTunes' default preferences settings:  Copy the entire iTunes folder (and in doing so all its subfolders and files) intact to the other drive.  Open iTunes and immediately hold down the option (alt) key (shift on Windows) so you get a prompt to select a library, then guide it to the 'iTunes Library.itl' file in the moved iTunes folder.

  • ITunes keeps creating a new iTunes Library instead of going to my actual iTunes Library on my external drive.

    My old computer died.
    Luckily, my iTunes library is stored on an external drive.
    My new machine is Windows 8 and my old machine was Vista, but I don't think that should cause any problem.
    When I run iTunes, it comes up like a fresh install on a new machine... every time. By default, it creates an iTunes folder in my local drive and as such, has no music in and is a 100% blank slate.
    When I point it to my external drive, and then import the library, it does it. All my music shows up -- after a long time, but it all shows up.
    If I shut down iTunes or reboot, everything goes back to zero again.
    The most disturbing thing about this is that I can't back up properly, because -- although in Preferences it's pointed at my external drive -- it's backing up my iPhone 5 to the local drive in Windows.
    Any idea what's going on here?
    I've gone through this process 5 times already and it's always the same.

    There are two main components to the iTunes library. The media folder which you can adjust via Edit > Preferences > Advanced, and the database file iTunes Library.itl which is normally found in <User's Music>\iTunes. You can choose or create a new iTunes library by holding down shift as you launch iTunes.
    In some cases third party software can interfere with the way iTunes updates its files meaning that either iTunes forgets the previously chosen location, or that the active database is deleted. AVG anti-virus and Sony VIAO Entertainment Platform typically interfere with the database. McAfee has been implicated in the corruption of iTunesPrefs.plist.
    See Empty/corrupt iTunes library after upgrade/crash for more details on how you might recover after the library vanishes.
    You may get some improvment by hosting your entire library on the external drive not just the media. E.g. Create a library at X:\iTunes where X: is the drive letter, then move the media into X:\iTunes\iTunes Media before adding it to the library. This will make it easier to backup the library to a second drive and move it between computers when the time comes.

  • How do I reimport iPhoto Library from an external hd?

    Hi all - apologies if this has been posted before (but, couldn't find exactly what I need in the forums). I think I need to rebuild/erase, whathaveyou, my current iPhoto Library on my Mac because I'm getting a perpetual error/alert:
    *"The Volume for "CDY_.0005.JPG" cannot be found. Insert the disk or*
    *connect to the server volume and wait for it to appear on the desktop,*
    *then try again."*
    *Here's what happened:* I originally downloaded some pictures and video clips off of Compact Flash memory cards into a new folder ('Photos') onto the desktop of an IBM Thinkpad. I then transferred that folder - 'Photos' - to a new external hard drive (250 GB, Western Digital MyBook Essential Edition). They are visible on the external. I then tried to tranfer this 'Photos' folder from the MyBook into my iPhoto Library by going to 'Import to Library' and then choosing the appropriate drive (i.e, my external MyBook). This folder and it's contents (i.e, the images and their respective folder in which they were placed) seemingly went into my iPhoto Library, and also seemed to organize themselves appropriately....what I mean by this is:
    All of these images/videos I'm talking about are for my grad project, and must be organized by date. I had one scouting camera at each of 26 different sites. Each of these sites has it's own folder....and each of folder (site) contains an album for each date the site was checked. So in other words, I've got LOADS of albums organized by date checked and site. *+I must preserve this structure or data analysis and, subsequently, my thesis, will be quite painful, cruel and unusual punishment!+*
    *By the way, I have tons of images and videos named "CDY_.0005.JPG" because of the way the scouting cameras save files to the memory card. Each time the card is cleared (each date I checked a site and downloaded images on a card), images are again saved numerically:
    CDY.0001.JPG.....CDY.0002.JPG etc etc. Also, these cameras were set up to take motion-activated video (they're infrared), and for every video it captures, it takes a still photo. So, every still photo is essentially associated with a video, and vice versa.
    This error/alert occurs when I try to view images that were transferred from the IBM/MyBook to iPhoto. Additionally, since I did the transfer, another qwerky thing occurs: Regardless of what I'm trying to do in iPhoto, when I open iPhoto and click *anywhere else* outside of the iPhoto window (such as back to the desktop or click to open any other program) I get this exact same alert, but it's always an .avi file, not a .jpg, and in this alert (.avi), I am forced to force-quit iPhoto because if I hit cancel, the pinwheel appears indefinitely and never goes away, at which time I forequit and see 'iPhoto (not responding). Essentially rendering iPhoto useless for my purposes (I've got to be able to go back and forth between Excel and iPhoto, for example, and cannot do so because of this alert).
    So, I feel like to I need to start from scratch to fix this problem (through a series of discussions with Apple reps and the Mac gurus, I was told this is probably due to corrupted files, I may need to rewrite the program etc etc). And...so...the real QUESTIONS:
    *Is this really the solution (backing up my iPhoto Library to the external, which I've done, then clearing my current iPhoto Library on my Mac entirely, then reimporting)?? I don't really have much time to fiddle with too many different solutions...if re-creating a new library seems extreme, I guess I really don't care, as long as it works.*
    *If I do this, and delete/clear all the photos in my iPhoto Library on the Mac, then reimport them from my MyBook external harddrive, will they be imported in the same structure as they were before I deleted them from iPhoto? Will I still have all photos in the same albums under the same folders? It is essential for me to retain this structure, as I am analyzing images/videos for my grad project and all these images are organized very specifically by certain dates. *Is it possible to do this??** I was told that if I burned my Library, or folders, onto a DVD, and then brought them back into iPhoto, this would retain the folder structure. True??
    Thankyouthankyouthankyou in advance if anyone has some thoughts! I'm still relatively new to Macs, so rudimentary, kindergarten step-by-step thoughts are encouraged....Cheers!

    TD-
    Great, thanks for helping. I think I've got some useful info for you. I went throught the process you suggested, here's what I found out:
    I viewed the rolls through the Pictures/iPhoto Library/Originals route. I see the rolls, but I do NOT think these images from the pc are there. Here's what's weird: Towards the end of my 'rolls' list (they're not named, just numbered), the rolls jump from 495 to 503. Though I didn't check all those rolls up to 495 (it would take forever!), I'm pretty sure those are my 'ok' files/rolls. I don't think they house any of the pix I was having issues with (the ones that came over from the pc). BUT...roll 503 DOES in fact have one image, and here's what happens when I click on it:
    Only that jpg icon shows up where the picture normally would be viewed, it has a shortcut arrow in the bottom left corner (like that which would appear on any shortcut icon on your desktop), and the info for this image is different than the other ones:
    Kind: Alias
    Size: 4 kb on disk (usually these scouting camera images are upwards of 800 or 900 some kb)
    Created: 9-23-07
    Last opened: fetching...
    And finally, the infamous alert comes up for this specific image: "The volume for bla bla bla cannot be found...." etc etc.
    I'm pretty confident that the missing rolls that should be after 495 are from when I tried to transfer the folders of images from the IBM because those are the very last things I 'imported' into iPhoto. Thoughts??? One other weird thing I noticed, too, was some of my rolls do NOT show all of the images that are in the iPhoto folders...in other words, say roll 300 shows 4 images in the 'Originals' folder you asked me to go to. Well, each roll was created when I would download each card, so essentially I know that each roll represents each time a card was downloaded. But, when I go straight into iPhoto and look in that folder that represents when I downloaded each card, there are many more images there than are in the 'roll' folder for the same download...yikes, does that make sense?!
    Thanks again...I feel we're getting somewhere at least!

  • I have two apple id's one from my old laptop and one from my iPhone. I saved my iTunes library to my external hard drive and then tried to transfer it to my iMac. My music skips like a scratched cd now and I can't add any to my iPhone. Help please!

    I have two apple id's one from my old laptop and one from my iPhone. I saved my iTunes library to my external hard drive right before my old mac laptop died and then tried to transfer it to my new iMac. Now when I try to play my old music it skips like a scratched cd. Also, now I can't add any music to my iPhone unless it was purchased recently through itunes and downloaded through icloud. I tried to "Organize" my library in hopes of correcting the problem but my iMac just ejects my external harddrive part way through. Please help!

    Ejects the harddrive?
    Of what did your old Mac die?
    It sounds to me like you have some file corruption somewhere.  Either in the transfer of your library to the external or the external itself is flaky if it keeps ejecting.

    Create a concatenated disk set
    Increase storage space with a concatenated RAID set (also called “Just a Bunch of Disks” or JBOD). If you need one large disk, but you have only several smaller disks, you can create a concatenated disk set to use several small disks as one large disk.
    Open Disk Utility, in the Utilities folder in Launchpad.
    Select one of the disks that you want in the set, and then click RAID.
    Click Add (+), and type a name for the RAID set.
    Choose a format from the Format pop-up menu. Usually you’ll choose the Mac OS Extended (Journaled) format.

    Note that the biggest CON to concatenated RAID configurations is vulnerability to volume failure. If either disk fails, the whole volume fails.

  • Restoring aperture library from an external hard drive?

    I have a major issue with my aperture library. It crashed completely and it turns out that the back up I have on my time machine was corrupted because of a hard disk error. I found this out after buying a new mac and while trying to migrate the old library to the new mac. I kept getting error message -36.
    The situation is now as follows:
    - I have the full Aperture library on an external hard disk that I recovered from my crashed mac
    - I can acces and copy the indivial pictures via the master folder, but cannot copy the entire library. If I try this it give me an error (-36)
    - I can see the individual photo files via (click, 'view content'), and can copy them in groups, but not as a whole. It turns out that If I try to copy the master folder, there are some corrupt images there and the copy exercise then quits automatically. It does not allow me to delete the corrupt images.
    - when i try to restore the the library via aperture (so opening it with aperture) it keeps saying that my 'permissions' are not set correctly.
    Does anyone have an idea to copy the library (24gb worth of photos) without having to go in and copy group by group eliminating the corrupt files?
    There must be some way to rebuild the library on my new mac, from the hard disk, as I can see and access the individual pictures?
    Thanks!

    - My old mac ran on Snow Leopard.

    +the problem is this, almost every time i start my imac, launch itunes and then play a track purchased from an old itunes account, it keeps asking me to authorize that account. even though i have had previous macs containing itunes content on this old account, it has always played with no issues at all. now then... to try and remedy this, i first of all uninstalled itunes COMPLETELY and reinstalled. this seemed to do the trick but after a few days, it all started again.+
    Did you unauthorize your old Mac and authorize this one? You only get a maximum of 5 machines, so maybe you're past that or haven't authorized the new one - to do that, open iTunes, click on Store in Menu. Now, there should be two options: authorize or de-authorize this computer. Click on authorize and report back with whatever message you get.
    +on to my second issue, Aperture. the app works fine except, like itunes it constantly asks me to enter the serial number from the box. please note that this is a legitimate copy purchased from the apple online store and i used it for about a year on my old macbook pro with only having to enter the serial during the initial installation.+
    The Aperture SLA states that you can install it on two computers - a desktop and a laptop. I don't know if there is any protection embedded in the DVD (if you've already had it installed twice), but if the issue persists, I'd contact the Apple store (since you said that is where you bought it) and ask - or, if you're covered by warranty, simply call Apple. Or, if not, make an appointment at your nearest Genius Bar and get answers there. It is perfectly legal to install it again as long as it no longer exists on the old machine - and I don't think it has anything to do with hardware, sounds more like a glitch. Oh, and have you tried to install it fresh, enter the serial, open it to see if it works and then copy over the library?

  • I recently transferred my itunes library to an external hard drive. Now I get the error message 'the original file could not be found. Could you like to locate it' when i try to open songs. My iPod syncs ok.

    I recently tranferred my iTunes library to an external hard drive. Now I cannot open songs and get the error message ' The song "***" could not not be used because the original file could not be found. Would you like to locate it'. This applies to all 9742 songs!!. My iPod still syncs ok, but I can't play songs on the PC. Can anyone please help.

    It would help to have more background about your iTunes collection such as if you keep it on an external drive, or if you have moved or renamed anything recently.  iTunes is very sensitive to you renaming or moving files or folders involved with your media.  iTunes only keeps a reference to where a media file is located  and then goes to look for it when you try to play it. If you have changed things since it was added to itunes then it's like me sending you to look for a friend in my addressbook but that friend has moved.
    The other possibility is your computer is starting to lose files.  Again, the computer uses a reference database to tell it where on the drive to look for a file. If that database gets corrupt then it starts losing files.  Use Dsk Utility's first aid to verify your hard drive.

    iPhoto library is on external HDD
    I was in a slideshow, with around 1,911 photos in it. About halfway through, my Macbook ran out of battery. Now when I restarted and charged the Macbook and reopened iPhoto, the slideshow won't advance through photos, and I can't figure out any reason why it would do this.
    I thought it may be corrupted, so I deleted and reinstalled iPhoto library, iPhoto itself, and disconnected and reconnected my external HDD.
    This didn't work, the photos still won't advance.
    I don't know any reason why this would be happening, and there is ample space on my internal drive.
    I'm happy to provide more information if needed!
    Many Thanks,
    James

    Make a few tests, James, to narrow down the problem and find out, if the slideshow is corrupted, your iPhoto Library, or settings in your account.
    To test, if only your slideshow has a problem, create a new slideshow, just for testing. Just use "File > New Slideshow" and add a few photos. Does this slideshow play correctly?
    If the test slideshow does not play either, create a new iPhoto Library. Use the File menu in iPhoto: File > Switch to library > Create New. Import a few photos and create a slideshow.  Does it play?
    If even a new library does not solve the problem, test in a different user account (see this document:  Isolating an issue by using another user account - Apple Support):   
    This process involves creating a new user account, logging in to it, and testing for the issue.
    Create a new standard or admin user account in Users & Groups preferences.
    Use these instructions for OS X Mavericks.
    See these instructions for OS X Mountain Lion.
    See this video, or these instructions for OS X Lion.
    Optional: If you have any specific files you wish to test with, copy (don't move) those items to the /Users/Shared folder in the Finder.
    Log out of your current user account by choosing Log Out from the Apple () menu.
    Log in with the new account you created.
    Attempt to reproduce the issue you were seeing in your regular user account.
    After you have completed testing, log out of the test account by choosing Log Out from the Apple () menu.
    Log in as your regular account.
    After you have completed all testing with the test user account, you may want to delete it. You can delete an account in the Users & Groups pane of System Preferences.
    Note: Prior to deleting a test account, make sure you are completely done with it. If you have files in the Guest User you wish to keep, you should copy them to the /Users/Shared folder .
    If you should find, that slideshows only play in a new user account, post back.
