Fusion Drive New Partition Problem
Hi everybody,
I'm having trouble while creating new partiton on free space area. After highlighting free space area i click plus icon and rename partition. After click apply but utility doing nothing. And log window says "Preparing to partition disk". But no action started. Please help me getting 700 gb free space back.
That 2.2 TB partition is how Apple solved the problem of Bootcamp not working with 3 TB drives. The one parition is split so the first partition fits within the allowable partition size of 2.2 TB, needed for the Windows installer to work. Partition 0 is then split again to allow the bootcamp partition to be added at the end of partition 0:
I had the same problem as Maxia, with my first attempt installing Windows failing and getting the two partitions. I got to step 3.4 in the Boot Camp installation guide. After formatting the BOOTCAMP partition, then clicking on Next, the Windows installer said it could not find the specified partition. I went back to Mac OS, deleted the Boot Camp partition using Boot Camp Assistant, did it again from the start, and got the same results. I finally got it to work by rebooting using command R, to get into OSX recovery mode, choosing Disk Utility and running Repair Disk Permissions on the OSX partition. I then rebooted to the Windows install procedure, and everything worked as it should. I'm not 100% sure that repairing the permissions is what really did it; maybe just exiting the Windows installer, rebooting to Windows, and running the installer again would do the trick.
I also had a problem getting Boot Camp Assistant to download the Windows support software; as an alternative, you can download them directly from the Apple website at http://www.apple.com/support/bootcamp/downloads/. I also had problems getting the Nvidia graphics driver to load correctly in Windows, but on the third manual installation, it worked. All this should have gone a lot smoother, but in the end Windows 7 looks fabulous in the iMac 27" monitor, and the iMac 680MX graphics card is quite impressive. This is the way to do serious gaming on an iMac, with the only cost the Windows software, which is just under $100 on Amazon, for either Windows 7 or Windows 8 (the OEM System Builder Pack).

Like the question suggests, I'm thinking about purchasing one of the new 27'' iMacs and I'm wondering if I'd be possible to repartition the 3TB fusion drive to use the 128GB SSD part only for the OS.
Thanks a lot for this fast and helpful reply!
€dit: I accidentially clicked on "This helped me" instead of "This solved my question" and now it seems like I'm unable to change that :/ -
Fusion Drive - How to resize partition?
Hello there.
I've been searching google for many hours on how to resize (make it bigger) fusion drive bootcamp partition, without doing it manually (deleting/creating new)
Since i have MANY games and such, I dont want to reinstall / redownload them again.
I can't use Camptune, it doesn't support fusion drive.
Is there a program out there supporting resizing for fusion drive?Can you make a clone / restore system image?
You may have to nuke your partitions but Restore Mac OS partition and Windows would avoid reinstallng. -
Cannot erase/partition Fusion drive
Hi everyone,
When I got my iMac, with a 1TB Fusion drive, I partitioned it, with a small partition running OS X and apps, and another larger one, to contain my user files - photos, documents and so on.
Now I want to sell my iMac, and I want to re-partition my Fusion drive, to only one partition, like when I bought it. But it cannot be done. Se screenshot bellow. Everything is greyed out.
I have tried to boot into reinstall mode, via CMD-R, with no luck.
I have tried running OS X from another USB drive, no luck.
And the one partition listed in the screenshot, won't mount. Have I messed up completely?
Best regards
Soeren VedelBoot into your Recovery HD using Internet Recovery (Command+Option+R). You should see a spinning globe and it should take a few minutes to get to the OS X Utilities menu. This boots into Apple's server.
Open Terminal and type: diskutil cs list
Copy the Logical Volume Group UUID which is a string of letters/numbers/dashes. This should be the 1st line after the above command.
Type: diskutil cs delete <LVG UUID from the previous step> (without the brackets)
After the delete completes open Disk Utility and you may see your two drive (SSD, HDD) in RED. You will be prompted to IGNORE or FIX. Choose FIX to recreate your Fusion Drive.
Close DU and select Reinstall OS X from the menu list. After the reinstall completes Shutdown. Your Mac is now setup to factory OS. -
3TB Fusion Drive 3TB: very very slow boot time
Hi all,
I replaced my beloved 2009 Mac Pro Nehalem with a brand new iMac 27" with Core [email protected] Ghz, 24 GB Ram, GeForce GTX 780M and a 3TB Fusion Drive.
Big problem: the boot time is 2 min and 48 seconds, yes 168 seconds.
I used Migration assistant to configure this machine from my last MacPro TimeMachine backup.
Apart from boot time, the iMac works fine and the disk tests with Blackmagic show a writing speed of 300 mb/s and a reading speed of 580 mb/s.
Nothing else seems wrong, but the boot time is terrible.
Any suggestions?
Thanks,

IMac Retina 5k Display with 6 TB Fusion Drive
For no good reason Apple offers no BTO option for build-in state of the art 6 TB hard drives as Fusion Drives in the Apple Online Store. Those drives work as Fusion Drive without any problem in customized iMacs already. I have seen it! So why leave out this option? Is there any way to get a BTO Retina iMac with 6 TB Fusion Drive? Maybe a premium reseller?
Were you able to resolve this? I have the same issue and the marks look almost exactly the same...
Called Apple Care and they told me to take it in to an Apple Store, which I'll do after I backup everything. -
More boot camp problems new 5k imac 3 tera fusion drive
there seems to be problems with Yosemite and boot camp assistant
i'm cross posting this to the iMac forum but I spent hours online with apple tech today and none of the several foks I talked to there had even seen a 5k 27" yet and my call back from Cupertino and engineering is no till tomorrow so I thought I should post here too
MMy bto 5k shipped from China sunday night and arrived in Maine this morning.... Amazing when you think about it for a bto
iinstallation and set up we're going fine and I started up boot camp assistant to create a temp boot camp while I wait for my thunder bay 4 box to take the drives for my old Mac pro when boot camp will have a1 tera SSD all to itself....
so carved off a 700 gig boot camp partition which the assistant formatted fat I then plugged is the lighting to FW adapter in a LaCie 2 tera fw 800 drive to act as a bridge to my LaCie DVD burner which uses the old fw400 cables and inserted my new shrink wrap win 8.1 retail 64 DVD and up comes the win 8 install in very tiny type in a tiny window which got a bit of a laugh out of me.
And I go through it to the point of selecting that boot camp partition and then said it could not use a fat partition and I should reformat it from the win 8.1 installer which I did and then it said it could not use and unknown partition so I said great and booted back to 10-10 and the boot camp tool to put things back and it said it could not I then went to disk tools and it also said the 3tera fusion could not be either reformatted or put back to a single partition I was on with tech support where I went up through 4 levels of support due to the 5k bto which most had no knowledge of. We tried the optioncommand r to get to DT and the same problem as did going to reinstall from the net which after a 30 min down load could not reformat either it is now kicked to Cupertino with a call back tomorrow
( At this point all I want to do is put the computer back in the condition it was in when i started with a plain Yosemite on an unpartitioned 3 tera fusion... Then deal with boot camp when it can have its own drive)
am betting it will take a Unix comand line to reformat but be aware there may be boot camp issues with my configuration
and any help here will be great fully receiveddiskutil list

Can't back-up new iMac with fusion HD. The back-up proceeds to within 10% of the total storage needed and then the "of" number increases. I suspect there is a problem with backing up the fusion drive. We have a new 3 TB time Capsule. I tried excluding different parts of the software from the back-up but it didn't make any difference. I even tried exluding "invisible items" to no avail. Any ideas?
When you setup the wireless and ethernet in the computer.. ipv6 will be on automatic.. this is wrong for the latest TC firmware and airport utility. http://support.apple.com/kb/TS4597
Go to the wireless and ethernet setup in preferences and change ipv6 to link local.
Once you do the big backup by ethernet the wireless will function fine for incremental.. it is obviously not estimating the size correctly..
A full back-up on the iMac would be about 650 GB. The partial updates that I have been trying start out at 115MB and keep growing indefinitely. The original back-up never finished nor have any of the follow-up attempts.
The first estimate should be the full backup but it will keep growing as the backup advances.. I would also delete any inprogress files to make sure it is not messing up .. delete even a sparsebundle if there is one for the imac on the TC and start afresh once you have ethernet connection.
See A10 here.
Pondini may have some other clues there to give you an idea of why the backup is slow or not finishing.. there is a lot of issues with TM when it decides not to work. -
I am trying to install Windows on a new iMac w/3TB Fusion drive. The system crashed on my first attempt but appears to have partitioned the drive correctly before crashing??? So, what size partition does Windows 8 need to operate effectively? Is "more" better??? or just over-kill? And, has anyone installed Winodow 8 on an iMac...and how did it work? Would apps like "Parallel Desktop" or "VM Ware Fusion" be a good idea and troubleless?
I will try again but not too confident that it may get worse before it gets better.
Regards....?
P.S. I configured this iMac with the i7 processor 3.5GHz with Turbo Boost to 3,9GHz. When I select "About this Mac" it diplays my i7 processor as a 3.4GHz instead. Do you think they ran out of the i7 3.5GHz and shoved a i5 3.4Ghz in the iMac to meet deliver schedule??? I there a way to check the real-time speed of my processor??.It depends on your uses. See > https://discussions.apple.com/docs/DOC-3321 Windows 8 works properly in Boot Camp, always that your iMac is compatible > http://support.apple.com/kb/HT5634?viewlocale=en_US&locale=en_US You can only use the 64-bit Windows 8 edition.
Respecting to your processor, you may want to contact with Apple, as they may have sent you the iMac with a wrong processor -
DIY Fusion Drive Problem (8,2)
Hey,
I wanted to go a step further and create my own DIY Fusion Drive. I had no problems installing the new ssd (128gb Samsung 840 Pro) instead of the hdd (standard mac hdd) and moving the hdd to the place where the optical drive has been.
I then proceeded to boot from a recovery USB Stick runing the mountain lion recovery partition on it. I configured both of these drives without any problems and finally created my Fusion Drive (visible in disk utility).
But here are things getting worse. My original plan was to recover from a TimeMachine Backup i created right before I started working on the Fusion Drive. But no, it said an error occured and I should restart the PC. After googling this error a little bit (and trying the recovery over and over again, different attempts to repair the time machine, which doesn't seemed to be broken etc.), I came up with the idea that my TimeMachine data could be corrupted and a whole backup is not possible. No problem I thought to myself.
You just try to install Mountain Lion fresh with your Recovery USB Stick and then get one or two folder from your backup that you need. But nope, installing Mountain Lion aborted with an error too while checking if my MacBook would fit the installation or something.
Last try: Cmd+R to start internet recovery. Downloaded the whole thing. Now I was able to reinstall LION fresh on my system (which of course would be the basic installation since my macbook came with Lion). Problem is: Lion doesn't know anything about Fusion Drive and I couldn't select any drive to install it on.
Right now I'm really thinking about installing the os on the ssd alone, what I didn't want to do. But I'm not seeing a possiblilty to get the system back up and running they way I wanted it to.
Now it's on you guys. My last hope. Do you have any ideas on how to fix this problem? I read so many guides and neither of them came up with the problems I have. They just say "and after configurating your fusion drive, you just install moutain lion again and you're good" :|
Thank you very much,
MrMützeI just tried what would happen if a delete the Fusion drive again. I was able to start the installation process of LION to my SSD, but Mountain Lion still aborted with an error while evaluating my system. So it shouldn't be a problem associated with the FusionDrive.

I have a MacBookPro 9,1 (mid-2012, non-retina) running OS X 10.8.2. Here is what I have done to my system:
Installed Windows 7 x64 Pro to a boot camp partition; installed all windows updates.
Using WinClone, save an image of this boot camp partition.
Removed optical drive and HDD.
Installed HDD in place of optical drive.
Installed SSD in place of HDD.
Booted to recovery partition, installed OS X on a flash drive.
Booted to flash drive, created fusion drive using [MacWorld's instructions](http://www.macworld.com/article/2014011/how-to-make-your-own-fusion-drive.html)
Booted to recovery partition on flash drive.
Restored system to fusion drive from a Time Machine backup. Unfortunately, it seems that because I never installed OS X on my fusion drive, I do not have a recovery partition. But that's an issue for another day.
Using Boot Camp assistant, created a boot camp partition on my HDD.
Using WinClone, restore my Windows installation from the previously created image.
Now, Windows boots to a black screen telling me that it can't find a bootable device. I have tried a few things to resolve this, all without effect:
I know that VMware Fusion has to prepare a boot camp partition in order to virtualize it, so I figured it might inadvertently fix things. Alas, while it *did* successfully boot my boot camp partition into a virtual machine, I still can't boot into Windows.
I figured I'd just try to reinstall Windows. Surprisingly, my system booted to my Windows install disc, which was in my original optical drive (which I had put in a USB case). But, Windows refused to install, giving me a an error 0x8030024. It seems the solution to this issue is to disconnect all drives but the one on which you want to install Windows, which is something I would dearly like to avoid. It would be a pain, but more than that, I'm afraid it would bork my fusion drive, even if I'm careful to never boot to OS X with the SSD disconnected.
A lot of places said that this error results from a borked MBR, and suggest using a tool like gptfdisk to rewrite it. I followed the instructions [here](https://discussions.apple.com/thread/4144252?start=0&tstart=0), but *that* didn't work either.
I am now completely at a loss as to how to proceed, and Google isn't much help either.
In conclusion, here is some information that you may find helpful:

1. New Mini with internal 500GB with Mountain Lion(ML), put into an external FW enclosure, so the Mini can/could be booted using an external drive for contigency.
2. Replaced internal stock HDD (500Gb/5400rpm) with SSD/HDD (256Gb SSD/1TB 5400rpm).
3. Installed W7 x64 on 64GB partition on HDD, which was a single-partition drive to begin with.
4. The remaining HDD partition and the entire SSD was put into a Fusion drive.
5. Using Command-R, new ML installed on Fusion HD.
Here is what I currently have...(Disk0 - SSD, Disk1- 1TB HDD, Disk2 - Fusion, Disk3 - External FW).

How to reset 3TB fusion drive to original partition scheme
When I first purchased my 27" iMac in early 2013 I was unable to use Boot Camp to create a Windows partition (with the version of OSX it shipped with bootcamp was initially disabled but added in an update later). I found a guide online for untangling the Fusion Drive partitions and essentially setting up bootcamp manually.
However, a few days ago I had Windows 8 get screwed up and needed to reformat. I figured that since Apple now updated Mavericks to allow my machine to use bootcamp I would start from scratch and do it properly. The problem is, I cannot seem to get my machine back into a "factory default" setup. I tried removing the CoreStorage volume and letting the Disk Utility tool "reset" the drive, and that -seemed- to work. I had one 3TB partition (according to the GUI) and re-installed OSX. I used Bootcamp to split 2TB for Windows (games) and leave 1TB for Mac. Everything went fine and I restarted into the Win8 installer. However, at this point Windows refused to install to the 2TB partition. I tried formatting it, and delete/create but it said it couldn't install to that partition. The confusing part is that according to Windows I had about 8 partitions (EFI and Recovery I understand but the rest I don't know the reason for).
So now I'm back at the OSX Recovery and this is what "diskutil list" is giving me. Why are there all these 524.3 KB partitions? I can't seem to remove or merge them. I know I should have recorded what the original structure is, but it's too late now. Can someone tell me what the 3TB Fusion Drive *should* look like, and how I can get back to that?

Can I partition a 3tb fusion drive on a 2014 imac27", with boot camp, to let me install windows 7?
I have used boot camp to create a partition for Windows 7 on 3 earlier Macs (iMac 24" 2007 / Mac Pro 2009 / Macbook Pro 2009) as well as a recent Macbook Air 2012.
My main reason for this is to use Sage Account/Payroll, and also a couple of other Windows-specific programs.
I have just replaced the old iMac with a new iMac27", with a 3tb fusion drive, and want to partition it to install a new oem copy of Win 7 sp1.
However, I found an article on this (link: http://twocanoes.com/winclone/support/installing-windows-on-a-boot-camp-partitio n-on-a-3-tb-fusion-drive) implying this might not currently be officially supported by Apple & boot camp assistant, and providing a workaround procedure to create 3 partitions. The article begins with this note: "Important Note: This help document is for reference only, superceded by updates to OS X that include support for 3TB drives and Fusion drive in Boot Camp Assistant. Use Boot Camp Assistant to create the Boot Camp partition."
I have two questions:
1 - Can anyone advise if updates have now been made, to provide this support for partitioning the 3tb fusion drive?....and if not, is this likely to change soon?
2 - If this is still not officially supported, can anyone advise if they have successfully created a Windows partition on the 3tb fusion drive & installed Win 7?
Thanks in advance.Based on Apple's knowledge base. this configuration is supported for Windows 7 x64 and 8 using Mountain Lion 108.3 or higher. Simply use BootCamp Assistant to set it up.

For your application, you might also consider virtualization software like VMWare Fusion or Parallels.
I use both BootCamp and VMWare Fusion. Fusion is much easier to install, more flxible, runs at the same time as your Mac applications etc. For typical applications, there is no notable performance degradation.
If you need high performance graphics for gaming, BootCamp is still the best way to go. For all other applications, I prefer VMWare. -
IMac with 3TB Fusion drive will not partition under Boot Camp
I have a 27" iMac with a 3TB Fusion drive and I am using 10.8.4.
I am trying to install Windows 8 Pro with Boot Camp. Everything starts well enough, but once I get to "Create a Partition for Windows" and setting a 505 GB Windows partition, it begins the process, but then seems to stop progressing with the status indicator pretty much stopped at a point directly under the "d" in the "Status: Partitioning disk.."
I've let it run for the past 1.5 hours and it hasn't budged.
This is not my first attempt at doing this on this machine. I tried manually partitioning with Disk Utility which pretty much ended up in a disaster that I was able to repair with some difficulty. That was covered in this thread.
I realize that 3TB drives were not supported under 10.8.3, but I thought that was fixed. Am I wrong?This is a bit of a guess and you might have do a bit of further reading to understand what I am trying to say but basically:
When you buy a Mac - its Hard Disks come partitioned using the GPT partitioning scheme that is used for the UEFI boot process (All new Windows 8 badged computers have UEFI now as well - Macs have been using it for years). This is opposed to the old MBR partitioning scheme that was used with the BIOS boot process.
There are quite a few limitations of the MBR partitioning scheme including:
1. A limit of 4 partitions per volume
2. A limit of 2 TB per partition
3. Poor support for AHCI
When you run Boot Camp - it turns your partitioning into a hybrid of the two, so you get stuck with all the limitations of MBR - with the second bullet point above I suspect of giving you issues.
You have a couple of possible solutions:
1. Test with having all partitions less than 2 TB
or
2. (Technical) Try and install Windows 8 in EFI mode - its a bit tricky at the moment and a little bit of work - but I have it working on my MacBook Pro (although I do have nVidia graphics driver issues that you may or may not encounter as well). See my wiki at multiboot.info for links if you want to attempt this -
Boot camp Yosemite Win 8.1 3tb Fusion Drive problems
Hi,
As many other have reported on the internet I am having problems installing windows on my iMac 27' late 2014 3tb fusion drive, where the partition I create falls outside the 2.2tb limit that prevents windows to be installed when selecting disk under the windows installation (i.e, same problem as Win 8.1, iMac Retina 3TB Fusion, Yosemite, Boot Camp fail!).
Is my understanding correct that this issue was solved in the OS X Mountain Lion Update v10.8.3 or was all they did to make sure boot camp could create a partition, but windows still couldn't find it?
I am using Yosemite 10.10.2 and I am wondering if for some reason they didn't include this update?
Has anyone successfully installed windows through boot camp on a 3tb fusion drive on yosemite, without 'manually' dividing the 3tb fusion into two partitions, and then creating the windows partition within the first partition?
Many thanks
iMac (Retina 5K, 27-inch, Late 2014), OS X Yosemite (10.10.2), 3tb fusion driveYou are correct. Please see - iMac (27-inch, Late 2012): Boot Camp alert with 3TB hard drive - Apple Support.
BCA should work. If you are running into any issues, can you post the output of the following Terminal commands?
diskutil list
diskutil cs list
sudo gpt -vv r show /dev/disk0
sudo gpt -vv r show /dev/disk1
sudo fdisk /dev/disk0
sudo fdisk /dev/disk1
