Hi All,


UK User with iMac 27" running Mac OS X v 10.7.5, 3.4Ghz Intel Core i7, 8GB 1333MHz DDR3, 251GB solid state internal HD & Seagate GoFlex 2TB External Hard Drive (networked via router).


I am somewhat exasperated with my issue now.


I have successfully hooked up the Seagate GoFlex 2TB ext HD to my network. It's connected locally to my router and is visible to my iMac, my Apple TV and my Sirus Stream XP.


Delighted with myself I thought it would be a simple task to transfer my iTunes library from my iMac to the Seagate. How wrong I was...


I have read umpteen webpages about the changing of permissions on both the iTunes Media Folder but also in iTunes itself. I am 100% percent an administrator with full permissions. I am using the method of redirecting iTunes to look for the library in the Seagate. This then allows me to "organize library" which will send a copy of the library to the Seagate. However, every time it goes through the Library prep process I get an error saying I don't have permission to modify the iTunes Media folder or a folder contained within it.


I have checked the permissions on each folder in it and the folder itself but I would appear to have access to all.


I have also checked the permissions on iTunes itself and I am again confirmed with read a write access.


I then got to checking the format on the Seagate. It is NTFS. I know that Mac OS X will read that but not write to it. However, for the life of me, I cannot get the Mac to actually recognise the Seagate in the Disk Doctor programme. I had planned on putting the drive into a Mac format.


Unable to do it via Disk Doctor I connected to the drive using the IP address via Safari. It worked well and got me to the stage where I can format the drive from NTFS to FAT32. Great I thought....




A little searching leads me to believe that FAT32 has a limit on files of 4GB. Sadly my iTunes file is a number of times so I need another solution.


Therefore, I ask for your help.


1) How can I convert my Seagate from NTFS to a format that will not encounter file size issues?

2) If this is completed will it then solve my other issues where the 'permission' to modify the iTunes Media folder is stopping me? If not, is there something else i'll also need to do?

3) Is there another solution that i'm missing completely?


I very much look forward to any advice and offer my thanks in advance for any responses.


Best regards

    Our iTunes guru Terence Devlin advises the following:


    1. Quit iTunes

    2. Drag the iTunes folder from your internal hd - located in ~/Music folder - to your external hd. DO NOT delete the original one from your internal hd... yet!

    3. When the transfer is complete, press and hold the Option(alt) key and fire up iTunes.

    4. A "Choose iTunes Library" window will come up. Click on the "Choose Library" button.

    5. Navigate to where the iTunes folder is located in the external hd.

    6. Within the iTunes folder, select the iTunes Library file and click Choose...


    That's it. iTunes will now display all your playlists, songs, movies, podcasts etc. At this point, should you wish, you can delete the iTunes folder from the internal hd to free up space.

    Hi Klaus,


    Thanks for the reply.


    I did also try the drag and drop method but the folder showed the grey 'no entry' sign and wouldn't transfer. I assume this is due to the NTFS formatting. In think that method may well work once I get the drive formatted but I'm struggling with that. The FAT32 file size issue would hinder the method you refer to from working. I will give that one a try once the drive can be written to the correct format.

    The external HD has to be formatted as Mac OS Extended (Journaled).


    A Mac cannot read NTFS formatted volumes.

    Thanks, but that's the issue I'm having. The Mac sees the drive but it won't show up in the Disk Doctor programme so I can't reformat the drive. The drive itself has a formatting programme but only allows to go to FAT32 which is unsuitable for the reasons mentioned previously.


    If someone can help me reformat the drive to the Mac OS Extended format then I suspect my issues will be resolved.


    I'm thinking of trying to connect it locally and see if that changes anything for Disk Doctor and if so then I can reconnect to the router and try the transfer again.

    You need to connect your disk directly to your Mac. You will then be able to used disk utilities to format the drive in Mac OS extended journaled.

    This will however prevent the disk from being recognized if you plug it into your router. The routers mini Linux OS can't handle that.
