How do I use External Hard Drive for my iTunes Library?

I have a Mac Mini that my iTunes Library has outgrown.  I want to use my Mac Air as my primary iTunes "sync" computer using an external hard drive. How do I move my iTunes library to the external hard drive? How do I get MacBook Air to sync iDevices?

Easy method 1:
Move or Copy entire working library from current location to the root of your external drive. Press & hold down shift (option on a Mac) as you click the icon to start iTunes. Click Choose when prompted, then browse to ..\iTunes\iTunes Library.itl on the external. If you copied the library across then test your new library works properly after renaming the original folder, before deleting the original folder to recover space.
Easy method 2:
If you haven't really started to build your library. Press & hold down shift as you click the icon to start iTunes. Click Create. Browse to the root of the external drive. Drag your media into ..\iTunes\iTunes Media\Automatically Add to iTunes.
Complex method:
Required if you've already tried other things and now have media & library scattered around. See the post make a split library portable.

  • External Hard Drive for large itune library

    Every time I click a song I have to "locate." Is there any way to have resolve that in one step without having to do it on each song?
    TRacy

    How do I do it?
    My external hard drive is connected to one computer. It gets turned on first. Then the other two. They are connected by a LAN. I have the external hard drive set to mount on the other two at startup. Now the external hard drive is connected to all three at the same time. iTunes on all three point to it, but the Library.xml file for each computer is on it's own startup disc. Only the music files are shared.
    If you are happy with the location of your files and you don't care about playlists and play count etc., open iTunes WITH THE EXTERNAL HARD DRIVE DISCONNECTED and delete everything in the library and close iTunes. Them turn on and mount the external hard drive, open iTunes and do File/Add To Library and point to the external hard drive.
    Moving the files by hand instead of letting iTunes do it in the first place is one reason iTunes can't locate them now.

  • First time using external hard drive for backup of computer....

    First time using external hard drive for backup of computer....it asks "Do do you want to erase disk?" In order to proceed, I have to say "yes" ... is that what I want to do? ...Seems like I'm skipping a step...

    To use Disk Utilities, attach the drive, open Finder > Applications > Utilities > Disk Utilities and then highlight the LaCie drive in the left panel of the DU window.  In the right panel, choose the Partition button top center of the pane.  Then decide how many partitions you want on the drive, one is just fine.
    Then choose the format, the default is Mac OS Extended (Journaled) which is prefered.
    Then name the partition or drive.
    Then choose the partition table, the default is GUID which is prefered.
    Then Apply and you will get to confirm that you want to erase and format the drive.
    Quit DU and you are ready to go.

  • I use an external hard drive for my Lightroom library and I notice that all the images shown on there are DNG. On my MAC hard drive I have images shown as NEF. I desperately need to free up space on my hard drive, can I safely delete these NEFs?

    however, I do point out that obtaining an additional hard drive and not throwing anything away seems a preferable solution to me.
    heidie22, dj_paige has a very good point there. I would not through away the NEF files; I would archive them to a external drive.
    By the way, I am assuming that converting RAW files to DNG is a decision you have made and not an accident.

  • How do I use external hard drive

    how do I use external hard drive and Photos? I keep getting a msg that there is not enough free space on your photo library volume - i even bought 500Gb of space on iCloud.... that didn't even work please help

    1. Drag the library to a volume formatted as Mac OS Extended, launch Photos with the Option key held down, select Other Library, and choose it. Alternatively, drag it to the Photos icon in the Dock.
    2. iCloud storage space is separate from that on the computer.

  • Using external hard drive for itunes from mac to windows

    Hello, I have an external hard drive for my itunes music connected to a G4. I just bought a laptop (windows) and would like to connect the external drive to it so it will read my music from the external hard drive. How can i do that?
    Thanks,
    M

    You will lose all data when you reformat so you must copy it elsewhere temporarily, as for the format go to: Applications>Utilities>Disk Utility>Erase, in the format dropdown select MSDOS (FAT) and in the name dropdown, type a name.
    Copy your data back to it and it will be accessible to windows and osx

    In iTunes 11 uncheck the preferences setting in in the iTunes Preferences panel "Advanced > Copy Files to iTunes Media folder when adding to Library"

  • I recently reset my computer and copy my music from an external hard drive to my itunes library.  When I click on a song to play i get an error message that says " the song could not be used because the original file could not be found".  need help

    I recently reset my computer and copy my music from an external hard drive to my itunes library.  When I click on a song to play i get an error message that says " the song could not be used because the original file could not be found".  But when I have my external hard drive plug in the song will play with no problem.  What do I need to do to play my music without having the external harddrive plug in ????????  Please help

    Because the location for each song in your library is on your hard drive.  If the hard drive isn't there, how can iTunes play it?
    You'll have to move/copy the music from your hard drive to your computer's hard drive.
    Basically, EASIEST way to do all this, if you don't care about your play counts, etc...
    -Delete EVERYTHING from iTunes, so that your library is now empty.
    -Go to "Advanced" inside of the "Preferences" window, found in the "Edit" drop-down.  You can also access Preferences by pressing Ctrl+, (Press Ctrl and the comma key)
    -Change your iTunes Media Folder Location to something simple, but on your computer. I use C:/iTunes.  Make sure "Keep iTunes Media Folder Organized" and "Copy files to...." are both checked.  You can close Preferences now.
    -Now, drag and drop your music from your hard drive into your iTunes library.  iTunes will automatically add the music to your library, as you would expect, and also creates a copy of each file to place into that iTunes Media Folder you just created.
    Shouldn't have any more problems...

  • I have an old iPod Classic with 80 GB (I think) of space. I saved all my songs in an external hard drive, but the iTunes library resided in an old computer (no longer working). Can I get the libray from my iPod and use it in my new computer (Windows)?

  • Using External Hard Drive For Time Machine

    Hi. I will be buying a new iMac and plan to use an external hard drive by Lacie for Time Machine backups. I haven't used an external hard drive for this purpose before -- previously I've always used Apple's Time Capsule. So, I don't know if I can leave the Lacie hard drive unejected and powered on even when I've shut the computer down. The Time Capsule never needs ejecting from the desktop and is always on, but I'm not sure if the same can be done with an external hard drive when using it for time machine backups.
    So, I just need to know if, when using an external hard drive such as a Lacie for Time Machine backups, I can 1. leave it unejected even when I shut down the computer? and 2. Can I also leave the hard drive powered on even when I shut the computer down? It would be good if I could do this because then it would just always be on and ready for hourly time machine backups without my having to remember to turn it on and the eject it when it's finished for the day.
    I'd appreciate any advice or information.
    Thanks in advance.

    What are you referring with "unejected"? You should know that LaCie drives have got three modes: "On" (permanently turned on), "Auto" (when you turn off your computer, your external disk turns off or you unmount it) and "Off". Choose the one you want.

    Of course. You can leave the external disk turned on when your Mac is turned off without any problem. In "Auto" mode you won't have to do anything in order to turn it on again

  • Using external hard drive for music files NOT in iTunes music folder

    Hi there. Due to lacking disk space on my computer I have all my music files (that I had before using iTunes) on an external HD. I can easily import these drives to iTunes (v.8) without copying them to the iTunes music folder. But when I want to synchronize my iPod the next time, iTunes cannot find the files on my external HD and I have to import them all again, delete all the duplicates and - worst of all - do all the playlist sorting again! Is there a solution to this without putting all my music into the iTunes music folder (I would like to keep it separated)? Thanks in advance!

    I use an external firewire drive to store my iTunes library on. One thing to be aware of...
    You need to go into your iTunes preferences, then to "Advanced", then select the location where you want to store your iTunes Music folder. In my case it is in a folder titled "Music" on my external firewire drive. The iTunes "Library" file is stored on your internal hard drive.
    The thing that can cause you problems it that....if you forget to turn on the external drive before you boot up your Mac, the iTunes library file will look for your music folder and won't be able to find it. So a new iTunes Music folder will be created on your internal hard drive, with nothing in it. You'll see all of your songs listed in your iTunes program...but if you try to double click on any of the songs to play them, you'll get an exclamation mark saying "cannot find file".
    If this happens, you need to delete the new iTunes Music folder on your internal drive (but not the iTunes Library file!), then quit iTunes, turn on the external drive, then relaunch iTunes....and it will find the original music folder.
    It's a hassle that I have had to go though many times, I keep forgetting to turn on that drive before launching iTunes.
    Oh, one other thing....about the way you worded your post. You aren't running short on "memory", you are running short on "storage"....they are two different things. Hard drives are storage, RAM chips are "memory" that run your programs.

  • Details needed for using two hard drives with one iTunes library

    I posted this under the iTunes section but now that I think of it, it's more of an Apple TV question since I'm only concerned about how it affects my 2 ATVs.
    I have a MacMini(G4) that acts as a media server for our 2 ATVs. I use one library on the Mini which has been using an external 750GB drive. However, I'm at nearly 95% capacity now and want to invest in another external drive and use both. So the question I posted on the iTunes section was...
    "With far too much content in iTunes (mostly for the Apple TVs) and after reading numerous posts about using external hard drives with iTunes I'm convinced that using two external drives is my best solution.
    However, I did want to understand a bit more about the details of how iTunes will manage or at least keep track of, the media. Specifically, I'm thinking of the case were I add a movie to iTunes library (of course it will not copy the file into the iTunes folder).
    What will occur if I later change any of the tags for the movie (e.g., name, genre, year, etc.). Will iTunes update this information and then update the Apple TVs once they resync with the iTunes library?"
    So for the very knowledgeable folks here on the ATV section, what exactly does iTunes do in this case? Will my genres be updated correctly if I change something even though the content is not copied to the iTunes folder?

    If you want to use two external drives to store your itunes content, there are a couple of ways you could go about it.
    You could choose to have just movies (for example) on one HDD and everything else on the other. You could further choose to have your itunes music folder on one HDD and have all content copied to it by default. When it comes to movies (in this example) you can place these on your second HDD and add them to itunes by using OPT-drag, which will temporarily disable itunes from copying the file to your itunes library.
    You could also entirely disable disable itunes copying files to your itunes music folder from the itunes preferences and manually manage all your content.
    Personally I'd just buy a 2 TB (for example) drive and ebay your old drive once you have moved everything from it to your new one.

  • How can I use single hard drive for both Mac OS and Windows without changing the formats and reformatting?

    I have a windows PC and a Macbook Air and a 1TB external hard drive. They said in order to transfer large files into the hard drive you have to change the format of your hard drive (which would be from MS-DOS to Mac Os extended) so how can I use my external hard drive on my windows PC without reformatting its files? Please heeeelp 

    Natively Windows can read and write to NTFS, FAT32, and exFAT while the Mac can read and write to FAT32, exFAT, and MacOS Extended.
    Option 1: You can purchase driver software for Windows to allow it to read and write Mac's MacOS Extended or you can purchase a driver to allow the Mac to read and write to NTFS.
    Option 2: you can format the hard drive for exFAT and use it with both Windows and the Mac without purchasing any special drivers. (Obviously the 4GB file size limit is why you don't want to use FAT32)

  • Kernel panic when using external hard drive for library

    I have been using an external hard drive to manage my iTunes library for over a year. As of today, I have had three kernel panics when trying to use iTunes. I was downloading a purchase from the music store and the first panic occurred. Subsequent panics occurred immediately on startup of iTunes. Using the guest account (with default internal drive library settings), everything works fine. Both drives have been verified by Disk Utility and all software is up-to-date. No clue how to proceed.

    Yes, but you need to have the external drive on and mounted when starting iTunes. You can add the external HD to your log in items list in System Preferences -> Accounts to handle this.
