    Hey everybody,
    First off I am running 10.7.4 on a late 2011 13'' MBP:D

    I am having some issues with partitioning my HDD. I am trying to give myself a 60 GB partition in anticipation of adding an ssd in the near future. I want to get a fresh install on there and have the apps set up how I will want them after the ssd addition, just to save myself time later since I have the time now. The problem I am having is with disk utility. Initially I tried partitioning before disabling file vault 2, it wouldn't let me, not really surprised about that so I let the decryption commence overnight. I then went and booted into the recovery partition and tried partitioning the drive again. The add (+) partition option was still greyed out and it was still telling me that there was encrypted information on the drive. I am fairly computer literate but new to macs and osx and their file system (I have been using linux and windows for years). What do I need to do to get disk utility to see my HDD as decrypted? I am thinking that maybe I should try repairing permissions but I don't see the correlation between the two. Any help would be great, I would really rather not wipe the drive and reinstall (although I do have a time machine backup and a super duper image).

    Thanks everyone!

    PS.
    I'm new to the forum, my name is Sean. I believe that I'll be able to answer more questions then I ask, I promise I'm not jumping in for some quick answers then running without returning the favors.:)

    More information

    Some additional information. I ran through the permission repair without issue. But, when trying to 'repair' disk, or 'verify' disk I get an error stating that it can't complete the task. The specific information in the history is: "Problems were encountered during repair of the partition map". I don't know what to do now. I'm out of buttons to push so to speak.

    Thanks again for your help

    Update # 2

    So it seems that the decryption process wasn't completed correctly. I did the standard fix it, booting from recovery and repairing drive and partition and fixing the permissions. When running diskutil from terminal I found that the CoreStorage logical partition is still in existence, something that isn't supposed to be there when the decryption process completes correctly. Now I know the problem, I don't know how to fix it without just formatting the drive. I'd really rather not format the drive and reinstall lion, although I suppose if I have to do that, I can get away without doing a clean install of mountain lion in a month. If anybody knows how I can 'complete' the core storage removal process please help.

    Thanks again.

    Final Update

    Okay so I had the idea of turning file vault on, canceling the encryption and then telling it to decrypt, hoping it would complete the core storage removal process. But, I can't turn file vault on. The thing prefpane tells me to restart, I do, go back in and it tells me to restart again. Tried it a few times just for kicks even though I didn't expect any change and I was right, no change. So basically all that did for me was confirm that this is an issue relating to decrypting file vault 2. No more updates now, all I can hope for is somebody knows how to fix this issue without formatting the HDD. I could probably play around in terminal but its fairly likely that I'll end up screwing it up and having to format anyway.

    Thanks again.
