Migrating music to an external hard drive for access by Windows

Existing discussion thread link: https://discussions.apple.com/thread/1715002?start=0&tstart=0
Hi,
I have a large (~212GB) iTunes music library that was created using iTunes on Windows. All music files, etc are held on an external drive. Now I want to be able to access my existing music library from my MacBook Pro running iTunes on OS X. When I launch iTunes I hit the key so I can select which library file it should use. I'm not currently able to select my iTunes library on the external hard disk.
I've tried following the steps covered in an existing discussion thread that I have found, Migrating music to an external hard drive for access by Windows & Mac, but that hasn't worked for me unfortunately. The linked post suggests renaming the library file (.itl) to remove its extension but the library is read-only. I've also tried doing the same when the external hard disk is connnected to my windows laptop and then switching back over to my MacBook Pro. But this has also not worked yet.
Any suggestions? Thanks.

  • Migrating music to an external hard drive for access by Windows & Mac

    Hey folks
    I recently migrated my collection of music to an external hard drive by:
    1) changing the iTunes music folder location from the default (Music/iTunes/iTunes Music) to my external hard drive through iTunes Preferences.
    2) Selecting "Consolidate library" from the Advanced drop-down menu.
    Afterwards, I moved my library file to the same parent directory I put my iTunes music folder in on the external (in fact, I moved my entire iTunes folder excl the music folder which was obviously already on the hard drive). When I restarted iTunes I held down OPTION and then chose the library file on my external as the iTunes library file to be used. This was all done on a Mac.
    No problems - all swell. But... I moved the library file to the external because I want to be able to use the external with multiple computers from which I can import music that will automatically be copied to the same folder (the music folder on my external) and managed accordingly. When I tried to open the library from my Windows laptop at home nothing happened. The library file I copied from my Mac had no extension, so I renamed it .itl so the Windows version of iTunes would pick it up, but selecting it as the new library did nothing.
    Q1: Are iTunes library files (I assume always .itl's?) interchangeable between Mac and Windows? If not this might explain why the library didn't load up.
    Q2: Is my method wrong? Is there a different procedure for getting multiple copies of iTunes on different computers and operating systems to all use the same library, saved on an external hard drive, which itself references music from the same external hard drive? Is this goal even possible?
    Q3: Is it possible to have 2 or more libraries for a given installation of iTunes?
    Bonus Q4: How is the album artwork saved? When I consolidated my music on the external, did this move the artwork across with it (integrated with each music file?) or was it still sitting on my Mac hard drive in the Album Artwork directory? I have since moved this folder to my external as well, when I moved the entire directory including library file across, and album artwork is visible when the library is open on my Mac, but I don't know whether its getting the images from the hard drive or the external hard drive.
    Okay last one - I swear! Q5: When I couldn't get the laptop version of Itunes to open my Mac library file, I imported all my music into the default laptop library which references the music files still all located on the external. Considering the 130GB of music I'm dealing with, this took a while, but what took even longer was "Processing album artwork", which dragged on for ages. What is actually happening during this procedure - is iTunes accessing an online database to find the artwork, or is it working with the artwork already processed and saved in the album on the external?
    Thanks very much in advance! Sorry for all the questions but I'd like to crack this thing once and for all.

    The procedure for sharing a library between a Mac and Wintel PC on an external drive is quite simple. I did this myself so that I would have my music available to me when I worked in my lab.
    First before you transfer anything to your external hard drive, the music library on your Mac should already be consolidated. Once that is done, transfer the iTunes folder (./Music/iTunes) to the external drive. Unless your music files are in a folder outside the iTunes folder—for instance, my music files are on a separate, larger volume on my Mac from the iTunes folder that is on the boot volume—copying your iTunes folder will put everything that iTunes needs onto the external drive.
    Now you have two options for using your library on two machines. The first, which I prefer, is to leave your Mac’s iTunes library in place and use the external strictly for the Wintel PC. In this instance, you would need to add the .itl extension to the iTunes Library database file. When you attach your external to the Wintel PC at work and choose the library, your should be taken into iTunes with your music library intact.
    In this instance, your external drive can also serve as a backup of your iTunes library because it is highly improbable that both your external drive and Mac Pro’s iTunes folders will go bad simultaneously. For backup purposes, you will need to place another copy of your iTunes Library database file on the external drive, without the extension, for your Mac; I have had issues with Macs recognizing .itl files. Of note, the content of your library on the external drive will be the same if you need to recover from the external drive, but as the Wintel PC will not update the database file without the .itl extension, any settings you change or playlists you add in Windows will not be transferred to the Mac unless you recover the Mac’s library from the iTunes Music Library.xml file that the PC would have kept current.
    In the second instance, if you wish to run your library off of the external drive for both your Mac and Wintel PC, you would follow the same procedure described above, but you would need to have both an iTunes Library (Mac) and iTunes Library.itl (Windows) database files. Effectively, this would mean that once a change is made on either system, it will not be reflected on the other. As you are most likely to add new songs via your home computer, you will need to replace the .itl file with a copy of the Mac database file whenever you add music, playlists, etc.
    Given the storage capacity of my Power Mac G5 and the logistics involved in managing a library stored solely on an external volume going between a Mac and PC, I find the second option to be more trouble than it is worth. For me, it is easier to maintain my Mac’s iTunes library then copy the iTunes folder over to the external drive overnight when I wish to make any updates (e.g., new content, playlists, etc.) available to my work computer. In the morning, I just add the .itl extension to database file before disconnecting the external drive and taking it to work.
    Now that your first two questions are answered, yes you can have more than one library, but doing so is poor database management. You should have all of your content in a single database and use iTunes to separate content. iTunes already separates music, movies, podcasts, audiobooks, etc., but further division of content is up to the user. iTunes has had playlists and folders for a few versions now, so it is quite easy to organize your library’s content in as simple or complex a folder/playlist structure as you please.
    How album artwork is saved depends on how you acquired your music. Music you purchase from the iTunes Store has its artwork placed into a separate artwork database built in the Album Artwork folder in your iTunes folder. I believe that the same occurs if you allow iTunes to find and import album covers. If you rip CDs or acquire music from other sources, you manually add the artwork, in which case the images are stored in the music files.
    Lastly, when iTunes has to build a library it can take a while. Your library is twice as large as mine and on a slow(er) laptop drive the time to built a library will be excessive. Unless iTunes is crashing or freezing, let it runs its course until the library build is completed. Also, if you have copied your music files to your laptop’s internal hard drive, you should not leave iTunes referencing the external drive. In the worst case, you would want to copy your iTunes folder from the external to the laptop’s internal drive’s default iTunes folder location. Remove the iTunes Library file and allow iTunes on your laptop to rebuild the library from the XML file.

  • External hard drive for Mac and Windows?

    Hey all,
    Is it possible to set up an external hard drive with a partition that has one side compatible with Mac and the other with Windows, similar to a Boot Camp setup on an internal drive? If so, how do I do that? Thanks for any advice you can give.

    Rekishika:
    Yes it is possible. Use Disk Utility from Leopard and partition the external drive to the desired space for each. Format one side with Mac HFS+ Journaled and the other with FAT32 (You can reformat the FAT32). You can also format both external partitions to FAT32 if you want Leopard and Windows to access (read and write)either one of them.

  • External Hard Drive for Mac to Windows?

    Today I bought a 3TB My Book external hard drive. The only reason I need this is to move my 2,000+ pictures and 100+ videos off my Mac and keep them safe. These pictures and videos are filling up my memory and I can't seem to do much else with the whole 10GB I have free.
    Setting up and backing up My Book with Time Machine seemed to be a breeze and I can see all of the items on it that I need to. Honestly, I didn't want to back up my whole computer, I didn't need to. All I need off the Mac is the pictures and videos and I must be able to move them safely to another computer, if I want to.
    So here's my problem, before I even attempted to clean off all the pictures and videos from my Mac, I wanted to make sure I could see them on the drive from my husbands Lenovo laptop which runs on Windows 8. The device is recognized when plugged in but in no way can he open the external hard drive to see any pictures or videos, or anything for that matter. At this point, I'm very frustrated, I don't have enough money to spend an arm and a leg on hard drive. But obviously, you get what you pay for..
    Is there any drive (I want something that's at least 2TB for future use) that will be able to transfer my pictures and videos from my Mac to a Windows computer, and vice versa? Is there any way that I can get this My Book to work with Windows 8 now that I've used it for my Mac? If not, it's going back ASAP.

  • Formatting external hard drive for MAC and Windows

    I have an external hard drive that I would like to make compatible with BOTH Mac and Windows. I don't want to split it but is there any way that I can make it compatible to where I can use it back and forth between both? I have classes and use Photoshop on both systems and need to be able to read and write to the hard drive from each system. Please let me know if this is possible and how? Thanks

    I have a 500GB external HDD which I had to format o Fat32 a while ago. I don't remember exactly how I did it, but I remember it was a pain in the *** and took forever (I was under Windows XP).
    So short answer to your question is yes. It is possible and as the above person said, you need to format to Fat32. Long answer is it will take some time and effort. Here are a few links to help you get started:

  • Formatting an external hard drive for Mac and Windows

    Hello,
    I just bought a brand new Seagate Expansion Desktop Drive (2TB) and am trying to work out how to format it. I want to move all my photos and movies to it from my laptop so i have more space. I have a Mac OS X 10.5.8 laptop but i also wanted to make sure it was compatible with other Windows computers in case i need to use it on someone else's PC.
    I've read through a few posts over the net and i am getting confused as i'm not IT-intelligent at all. I've seen there are possibly 4 different format types.
    Any help would be much appreciated.

    I have a Synology NAS as well as the Time Capsule.  If you look at the 3.2 beta program, the Synology actually attempts to replicate TC functionality in that you can use it with Time Machine on your Mac.
    I must say, Airport on the TC is definitely a nice feature!

    I can't see why this wouldn't fufill my needs, and take the place of a separate NAS solution (like the Synology, or iOmega, Seagate, etc....)
    Has anyone used this TC as such?
    Yes, you can do this and it's something I've been trying to do, but I'm currently having issues.  I have another thread stating I consistently get "connection failed" messages.  I'm basically storing my music/photo/video files on the TC and keeping my Mac hard drive fairly lean.  In terms of NAS functionality, the TC is very basic.  Synology/QNAP and others have a lot more features so don't rule them out.

  • Choosing an external hard drive for back up

    This is more for general advice than a specific question. Right now I have my hard drive partitioned and use the second as a backup with Time Machine. It will work for most situations but not all, such as a home fire or break-in (all my photos and music, lost forever!).
    What I want to do is buy an external hard drive for backup and keep it at work. I would then bring it home every few weeks to update, but otherwise not store it in the same place as my computer. That way I would never lose more than a few weeks worth of stuff. So, a few questions, the nature of which will let you know how much of a novice I am at this.
    1) Right now, Time Machine automatically updates once per hour. When I am using the external drive will I be able to set Time Machine up to only update my back up files when I connect the external drive. Is this difficult.
    2) Any suggestions on what kind of external hard drive I should buy, or what features I should look for would be appreciated. I live in a remote area, so something I can get from futureshop.ca would be preferable.
    3) My hard drive is about 280 GB. What size should I buy.
    Advice on any of the above would be appreciated. Also feel free to toss in anything else you think I should know or consider.

    This is what I am currently doing among 3 different backup disks (1 Time Capsule, a WD500GB, and a Lacie 160GB). You won't have to "set" anything up other than attach the new drive and select it in the TM prefs. Then when your done, reselect your normal TM disk.
    2) Any suggestions on what kind of external hard drive I should buy, or what features I should look for would be appreciated. I live in a remote area, so something I can get from futureshop.ca would be preferable.
    Most any drive will do, as you partition it correctly to begin with.
    *_How Should a Time Machine Hard Disk be Prepared?_*
    For Time Machine to work properly, the hard disk must be formatted “Mac OS Extended (Journaled)” and its’ Partition Scheme should be either GUID or Apple Partition Map.
    Time Machine is incompatible with disks partitioned as Master Boot Record (MBR). Unfortunately, this describes nearly every hard drive you can buy because MBR is a Windows partition scheme. (Naturally, this DOES NOT apply to Apples’ Time Capsule.)
    For some, Time Machine begins to perform as expected with a new external hard disk. But then the initial full backup or subsequent incremental backups fail. The user only later discovers the hard disk was still partitioned as Master Boot Record (MBR).
    One article on Time Machine made this observation: “Virtually everybody will have to open Disk Utility and repartition the disk as APM or GUID. It doesn't really matter which one because the Time Machine disk will not be bootable anyway. APM allows a disk to boot a PowerPC, GUID allows the disk to boot an Intel processor but both are easily digestible by Time Machine on either kind of processor.” [http://www.girr.org/mac_stuff/backups.html]
    It’s been recommended by many here that your reserve +at least+ double the size of your primary hard disk, that way Time Machine backups have room to grow as the size of your data grows. Additionally, the more space you give Time Machine the more history it can preserve. The less space you reserve for Time Machine the sooner older backups & deleted items will disappear.
    One poster recommended this regarding multiple partitions: “If you do create multiple partitions (half and half would be a good place to start), make sure you use the first partition for Time Machine, and the second for your own stuff (the first one will be on top in the graphical representation shown in Disk Utility; you'll understand when you see the partition tab). This way, you can expand the Time Machine volume at any later time by deleting the second partition. Disk Utility allows this dynamic re-sizing of volumes, but volumes can only be expanded toward the end of the drive, when a volume that comes after is deleted to create the room.” [http://discussions.apple.com/thread.jspa?threadID=1712437&tstart=0]
    Procedure
    Connect the hard disk you wish to use for Time Machine backups.
    Launch Disk Utility.
    It will appear twice in the pane on the left. (Make sure you recognize that it is different from the 2 icons that represent your Macs' internal drive.) The upper entry represent the device as a whole, including the controller inside. The lower entry represents the hard disk contained within the device.
    Click on the upper icon of the external hard disk.
    Select the "Partition" tab.
    For "Volume Scheme" choose "1 partition". (Choose 2 partitions if you intend on storing other data on the disk besides your Time Machine backups. Ensure that the two partitions have different names.)
    Name the disk.
    Format should be "Mac OS Extended (Journaled)".
    Click "Options".
    Select either GUID or Apple Partition Map. (See above for significance)
    Click "OK".
    Click "Apply". Then click “Partition”.
    Once the external hard disk is repartitioned, select it again in Time Machine preferences and use it for your backups. If you chose to create 2 partitions, then select the first partition for Time Machine backups, and the second for additional files/folders.
    3) My hard drive is about 280 GB. What size should I buy.
    Any TM backup drive should be +at least+ twice as large as your Macs internal hard disk.
    Let us know if this resolves your issue.
    Cheers!

  • 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...

  • Importing music FROM an external hard drive

    My dance studio has an external hard drive with over 15,000 songs in MP3 format, and I would like to be able to put some of those songs on an iPod. My problem: I do not want double copies of my 15,000 songs (one copy in the external hard drive and one copy in iTunes) as that would take up A LOT of computer space. Space I don't have. I have recently installed iTunes on the studio computer (preferring the program for my personal music), is there a way to import the songs from my external hard drive into my iTunes library with out making two copies of each song (in different formats as explained earlier)? Can you "tell" iTunes to find its music in an external hard drive?

    Check your iTunes Preferences. Go to Edit>Preferences>Advanced and see if you have "Copy files to iTunes Music folder when adding to library" checked. If you haven't then all you did was add a reference to the original location (the external drive) to iTunes without copying the song files them selves. With the external drive disconnected iTunes can no longer locate the file to play from. If that's the case you'd need to delete the songs from iTunes, change preference and add the songs over again.

  • How do I get iTunes to access music files on external hard drive?

    We moved all of our music to an external hard drive. The hd is always on and I connect to it wirelessly. I don't know how to get iTunes to use the library that is on the hard drive, can anyone help me please.

    iTunes expects to find its library in the ./Music/iTunes folder. To get iTunes to see music on another drive, you first have to create the library on your internal drive. Once you've done that, you copy the iTunes folder over to your external drive, and redirect iTunes to that drive, using an alias. (I originally did this in Tiger and it continues to work fine in Leopard. I don't know if doing it originally in Leopard would make any difference.)
    Note: If your external drive library is already too large for your internal drive, simply use as much of it as you can to create the original library on your internal drive. You can add the rest of it once you've got iTunes looking at the external drive. In this case, remember to name any "iTunes" folder on the external drive to something else, so you don't erase everything in the following procedure.
    Load up as much music as you can on your internal drive, making sure it appears in iTunes.
    Quit iTunes and copy the iTunes folder from your internal drive to your external drive (be sure you don't erase whatever's already on the external drive). Copying that folder to the root of the external drive is OK.
    On your internal drive, rename the 'iTunes" folder to something else (like orig_iTunes) -- or move it out of the Music folder.
    Open your external hard drive to the directory containing your iTunes folder.
    Cmd-Option drag the iTunes folder from the external hard drive to the internal hard drive Music folder, creating an alias in the internal drive's Music folder.
    Launch iTunes. You should now see the music from the external hard drive. If necessary, you can now add back any missing music, and it will automatically create the necessary music and library files inside your iTunes folder on the external drive. Once you've got them all added, you can delete both the orig_iTunes folder, and the folder on your external drive that served as the source for adding your library back in.

  • Why can't iTunes find the music from an external hard drive?

    I moved my music to an external hard drive to free up space on my old laptop.  Since I moved to a new laptop, iTunes never seems to find the music.  I have to go through and manually select a song for it to find it one and then it says should it use this to find the rest of the songs.  Then it crashes.  I have reinstalled iTunes tonight with no real improvement.  I want to be able to create a playlist to upload to my new iPad as well as updating music on my iPod but I can't do any of it.  Please, any advice!

    Has the new laptop given the external drive a different drive letter?
    The "missing file" error happens if the file is no longer where iTunes expects to find it. Possible causes are that you or some third party tool has moved, renamed or deleted the file, one of its parent folders, or the drive it lives on has had a change of drive letter. It is also possible that iTunes has changed from expecting the files to be in the pre-iTunes 9 layout to post-iTunes 9 layout, or vice-versa, and so is looking in slightly the wrong place.
    Select a track with an exclamation mark, use Ctrl-I to Get Info, then click No when asked to try to locate the track. (Due to a bug in iTunes 12 you currently have to say No twice!) Look on the summary tab for the location that iTunes thinks the file should be. Now take a look around your hard drive(s). Hopefully you can locate the track in question. If a section of your library has simply been moved, a folder renamed, or a drive letter has changed, it should be possible to reverse the actions. If the difference between the two paths is an additional Music folder in one path then this is a layout issue. I can explain further if that is the case.
    In some cases iTunes may be able to repair itself if you go through the same steps with Get Info but this time click Locate and browse to the lost track. It may then offer to attempt to automatically fix other broken links.
    If another application like Windows Media Player has moved/renamed the files then the chances are that subtle differences in naming strategies will make it hard to restore the media to the precise path that iTunes is expecting. In such cases, as long as the missing files can be found somewhere, you should be able to use my FindTracks script to reconnect them to iTunes. See this post for an explanation of how it works.

    Not a good idea.
    What you could do, is have the Library content on the external hard drive and simply tell your iTunes programme to look on the hard drive for your music etc.. However, once you set that up, that hard drive needs to be connected and ready to read, before you start the iTunes programme. If it isn't ready, iTunes will simply go back to the default location for the music, find nothing and then you'll be back here saying that you've lost your Library.
