Can't format former Boot Camp partition

So I stupidly erased my Boot Camp partition using Disk Utility rather than in the Boot Camp Assistant. And now I the partition is stuck as free space and i can't change it. When i select the free space in Disk Util, I can change it to Mac OS Extended and ExFAT as usual, but when I press apply, the progress bar appears for a brief second and disappears. Then it acts as if I never pressed apply; when I close the window, it says that I have unsaved changes. The free space does not appear as a drive in the left sidebar.

I have tried reinstalling OS X, I've tried returning to a time machine backup, I've verified and repaired the disk, but nothing has worked.

I'm left with 67GB of space unusable on my macbook now.

MacBook Pro with Retina display, OS X Mavericks (10.9.4)

Hello to Loner T, I am your new French fan. I had the same problem with the BootCamp disk and read all that you indicated before, i know nothing about terminal but i tried and... i'am busted. 😁

So, i'am looking for a simple explanation, my disks are already erased, i want just to have them in a single volume (Fusion Drive 3To) because now i see four of them, 3To in differents disks and another one with the SSD of the fusion drive.

I take a copy of what i see in the terminal and the disk utilities.

With this single volume, i'am going to install a new Yosemite and recover all of my stuffs with my Time Machine.

Can you help me, please? 😝

PS: My iMac is a Core i7 3To Fusion Drive late 2012.

Terminal:

-bash-3.2# diskutil cs list

😊.

But may I suggest a new thread containing this diskutil cs list and a diskutil list from the Terminal. You may have to use Command+Opt+R so your internal physical disks have no filesystems or files being accessed.

Nov 6, 2014 3:26 PM in response to Loner T

i'll try "Command+Opt+R" but i'am connected normally with Wifi and i can't see a possibility to select my Wifi, only the globe stop spinning and an error appears. "-2006F"

It is tricky to use Internet Recovery (Command+Opt+R) and WiFi. Is there a possibility of using a wired connection? It may not be able to download 1.8+ GB over wireless without some errors and may abort repeatedly.

Nov 6, 2014 9:39 PM in response to Loner T

Ok, going to try this evening to connect me wired to internet.

The interest? what favors compared with my usb key?

If you have OS X Mavericks on an external disk - OS X: Installing OS X on an external volume - Apple Support, it will work too.

Nov 7, 2014 5:30 AM in response to Loner T

Any difference between that solution and my Yosemite Usb key?

If the USB key has OS X 10.8.5 or higher it should work too.

Nov 7, 2014 10:15 AM in response to Loner T

No, i told you, i cannot format the disk, i take you a picture of the Disk Utility Interface.

When i launch an installation from the USB Key, I have these choices:

None of them invite me to format the entire HD of the iMac, if i install Yosemite, it would be only on one of them.

Yosemite DU is broken very badly.

You posted the output of diskutil cs list from Terminal. If you can post the output of diskutil list and boot from the USB key, I can give you commands to create a single 3TB Fusion drive.

Nov 7, 2014 10:44 AM in response to Loner T

Ok, let's do this! 🙂

These commands will delete all CS volumes and volume groups. Please run diskutil cs list to confirm. Do not touch Disk Utility UI, otherwise we will need to start all over again.

Please re-run diskutil list because OSX will change /dev/diskN where N will change.
