    Hi, this is my first post on MacRumors and I just wanted to ask a question. :)

    A few months ago I purchased this -> http://eshop.macsales.com/shop/SSD/OWC/Aura_Pro_Air_2011

    Specifically the 180GB version. I moved my information using a Time Machine backup and ever since have been happy with my upgrade. Unfortunatley, this morning when I was setting up Bootcamp, I got an error.

    'This disk cannot be partitioned because some files cannot be moved.'

    I opened Disk Utility and verified the disk.

    Error: This disk needs to be repaired using the Recovery HD. Restart your computer, holding down the Command key and the R key until you see the Apple logo. When the OS X Utilities window appears, choose Disk Utility.

    I did the following to find that it booted with OS X Internet Recovery. I'm on a WEP based network so it didn't find my network. I checked my drive to find that there was no Recovery partition. I still had my old SSD which was turned into a external drive using tools that came with my SSD upgrade. I found a Recovery HD on there and copied it to my desktop. (It's saved as a .DMG) Is there any way to actually install it into my machine?

    I'm using a Macbook Air 11" 2011 Model. It's currently running OS X 10.8.2. Thanks in advance. :D

    How exactly did you move your OS? If you installed it on the new drive you should have a recovery partition. When you reboot you hold the option key to select it. You don't actually need a recovery partition; you just need an 8GB flash drive imaged with the InstallESD.dmg file from the ML installer.

    You need to repair your hard drive so boot into the recovery partition on the old drive and use DiskUtility to repair your new internal drive. Use the repair disk option.

    How much free space do you have?

    Attach the old drive in an external case and option key boot to it. Now run Disk Util (from the external still) and do a repair disk.

    Then install the app Carbon Copy Cloner (free 30 day trial). Start the app then hit command-2 to start "Disk Center." Click the Recovery HD tab like in my screen shot then follow the directions to move a copy of Recovery HD from the external to the internal.


    As mentioned, you don't really have to have a Recovery HD, but it can come in handy for things like this.
