    I'm ready to burn this iMac. This is the second iMac I've gone through this problem on.

     

    I booted from the DVD drive by restarting the computer and holding down the C key. I then started the windows 8 installer. I then located this "ghost" partion and deleted the partion. It then labels this partion as unallocated space as seen in the picture below.

    Note when I select the drive labeled Drive 0 Unallocated space... all options are greyed out!

     

    When I close the installer and get back into Mac OSX, it shows that partition still exists, but it is now of the type "Free Space". All options are greyed out in disc utility and now my Hard drive shows that only 2.2 TB are available out of 3TB. So I've basically lost 1TB of storage space that is not formatable. Please help!

    Try this, as it worked for me... but with that fusion drive, you never know (!!!!).

    Use disk utility under the recovery mode, not from the OSX. This allowed me getting access to the greyed partition and re-agregate it into the "one fusion drive"

    Hope this will work for you....

    Reboot into recovery (command-r) erase the internal disk, select MacOS as the resultant format. Reinstall from your backup. (If you don't have backup then make one before you start)

    I have a Time Machine backup of all my files which is great.

     

    Tech support had me enter into recovery mode. Even after erasing the disc the partion remained. I guess I'll see what happens at 5:15 with my phone call in.

  • Raymond Jones1 Level 1 Level 1 (25 points)

    Well, another hour on the phone with tech support and no luck. He had me select the "Free Space" partition and try to delete it by clicking on erase free space button. It took over 3 hours to finish and nothin happened. I'm still in the same position. I cannot get rid of this "Free space" partition.

    This is the stupid partition I cannot get rid of...

    Even if I select the flyout where it says "Free Space" and try to change it to Mac OS extended journaled & hit apply, nothing happens. It doesn't do anything.

    Deleting free space will not change anything, you need to delete all partitions (except recovery) on the drive and then create a new one. Everything on the drive will be lost so backup first.

  • Raymond Jones1 Level 1 Level 1 (25 points)

    I've erased the drive three seperate times with Apple Support. We did it through disc utility in OS. We did it through disc utility in recovery mode and once in disc utility using internet recovery mode. I've reinstalled OS X 4 times already. That chunk of "Free Space" still remains.

     

    I've tried to do some research and it seems the only way to fix this is to return the drive and get a new one, use a program called iPartition or do some fancy magic using terminal. I have another phone call with Apple Support tonight. Just the way I want to spend my Friday night....

  • Csound1 Level 8 Level 8 (43,355 points)

    I am not talking about erasure, question, yes or no answer please.

     

    Have you deleted the partition(s) (not free space, not operating systems etc), you would do this from the partition tab of Disk Utility?

     

    (iPartition does not do anything that Disk Utility can not do) don't waste your money.

    Will iPartition work? I downloaded the demo and it seemd to be able to access the 'greyed out' free space partition that I was totally unable to access through Disk Utility in any way shape or form. I have a new drive waiting to be installed at my nearest Apple store, but would actually happily pay the £36 for iPartition if it saved me from the hassle of having to take the iMac in get it repaired and then collect it again.

  • Csound1 Level 8 Level 8 (43,355 points)

    iPartition does nothing at all that can't be done with Disk Utility, why waste money.

  • Wattonski Level 1 Level 1 (0 points)

    It'll have to be the repair job then,

  • Csound1 Level 8 Level 8 (43,355 points)

    Have you tried to delete the partition in Disk Utility (not erase the partition, delete it)

  • Wattonski Level 1 Level 1 (0 points)

    It's greyed out and can't be deleted through any method. This is the problem we are all having - the partition that was created during the boot camp process is totally inaccessible.

  • Steve Howells Level 1 Level 1 (0 points)

    I got MacOS back on my free partition just by doing a full re-install of Mountain Lion. That then got me to the stage of having two logical partitions but one Macintosh HD of 3Tb in size, and then from here I could install Boot Camp just fine.

     

    I think that basically when you first try to do anything with Boot Camp Assistant it will try to take you to the 2.2TB + 800Gb split on your hard drive, and then you can never come back from there. The point is you don't actually need to come back from there, as OS X will continue to treat your drive as if it only had one partition (or two, if you later install Boot Camp).

    OK, just so I am clear did you (in DU) select the drive in the left hand sidebar (the topmost entry) then go to the Partition Tab, select the Mac OS partition and delete it then continue through all other partitions. And you were booted from an external drive (or recovery) when you tried?
