Fusion Drive partition issue

Hello
I have partitioned my 3TB FusionDrive so that I have one main partition and one test partition: 2.8 TB and 250 GB (setup: late 2012 iMac, 3TB FusionDrive). After a couple of months, I tried to merge the two partitions — complete fail.
When I tried to erase the test partition, it suddenly became unaccessible and now there's no option to delete, merge, resize, whatever; booting into Disk Utility won't solve the make any difference either.
Could anyone explain the step-by-step, stupid-proof way of merging two FusionDrive partitions into one?

Fusion drive sound issue

I just bought a new iMac to record music and do graphic design. I was told to buy the fusion drive as it's faster and better etc, so I did. To my surprise, there's a terrible crackling noise after 10 minutes or so when I'm playing music through my quartet usb interface. Now, these are quality bits of technology and I need this fixed. I've seen a few problems about this online but I can't seem to get rid of the issue with updates. I didn't just blow €3000 for a big tv. Any help out there? Much appreciated.

Mac Mini (late 2012) w/ fusion drive - sleep issues

I am experiencing difficulties with my new Mac Mini (late 2012) w/ fusion drive.
All of the system preferences are set to NOT SLEEP EVER!
The screen saver is set to NEVER!
When I leave the unattended for more than an hor or two it puts itself to sleep and quits all open applications?
I did ZAP the parameter ram and there was no change?
Any assistance you can provide will be much appreciated!

Go to System Preferences->Personal->Security & Privacy and click on the ADVANCED tab in the lower-right corner. (You will probably have to click the AUTHENTICATE lock in the lower-left corner and provide your password first.)
Un-check the "Log out after X minutes of inactivity" box in the Advanced panel or set X to a large value that isn't likely to get in your way often.

Fusion drive capacity issue

Hi,
the strangest thing happened to my iMac regarding the capacity of the hard drive.
In Disk Utility, the capacity is 1.12 Tb, out of which 338.64 Gb are used, leaving 781.7 Gb available. Instead, if I get info on the Macintosh HD, which is the only partition, the available capacity is 330.13 Gb and 310.45 are used. This oddity also appears in the system report, which I pasted below and highlighted in bold.
I am running Maverick OS X 10.9.4 on iMac 21.5-inch, Late 2012 (2.7 Ghz Intel Core i5, RAM 16 Gb)
Any idea about what is going on?

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?

Fusion drive and backup/restore issues

Hi,
since I installed a fusion drive on my early 2008 iMac, consisting of an internal 256GB SSD and an (external FW800) 320GB hard disk, I occassionally run into trouble when system updates are pending. In the past, at worst the time machine backup couldn't be restored and I had to reformat and reinstall the system from scratch - which is not really comfortable!
Currently, running Mountain Lion, when I try to select the startup disk, it complains that Boot-Caches on the Boot-Helper-Partition cannot be created. Nevertheless the system starts fine (and runs fast ;-).
Before upgrading to Mavericks, I would like to know
- if someone else ran into similar problems with fusion drives, when updating/upgrading system software.
- Is it normal that a Time Machine backup cannot be (completely) restore a Fusion drive?
Yes, I know that having the harddisk part of a fusion drive externally is not recommended/supported by Apple - and my Mac is nearly 6 years old, but that would not explain why system updates/restores nearly always fail and sometimes the Time Machine backup drive has a broken file system (needed reformatting)! And I always checked the disks with Disk Utility prior to updating...
Any comments are appreciated.

You can file feedback here. The more who file the more the faster the issues may be fixed.
Also you shoud look on the CCC forums.

Windows will not boot to my boot camp partition on a DIY fusion drive - gives "No bootable device found" error

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.

My setup is very similar to your's, Ryan, on a Mac Mini5,2 and the ordering is different and Winclone was not used.
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).

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

Issue with Fusion drive (Late 2012 iMac)

I have a late 2009 iMac that has been backed up with Time Machine. I recently picked up a late 2012 iMac with the 1TB Fusion drive. When I first plugged in my Time Machine drive, I was asked if I'd like to transfer my files over. I did, and everything was working fine. I was using about 800GB of my 1.12TB Fusion Drive.
I recently decided to add a new partition to the Macintosh HD in order to put Windows on it. I did this through the Disk Utility. I noticed that it was taking an inordinately long time to create this partition. Finally, I realized that the Disk Utility was locked up. I was forced to reboot to fix it.
I went back and tried again and I got an error stating that the drive had errors and I couldn't make a new partition. So I attempted to "repair disk". That gave me an error "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."
So I rebooted into recovery. Recovery was absolutely no help either. It couldn't repair the drive, even though it had me erase all the data. So I downloaded 10.8.2 on my Mac Mini and made a boot disk out of my Thunderbolt drive. I booted into OS X and tried again to repair, thinking it would work since the Fusion was no longer the boot drive. No such luck. I then booted back into recovery and had recovery download and install a fresh version of 10.8.2. 2+ hours into the download/install, I get an error that says "OS X couldn't be installed because the disk Macintosh HD is damaged and can't be repaired."
Ok, so as a final attempt, I had recovery use my time machine to start over. That worked, kinda. It now shows my Fusion drive as being completely filled in Disk Utility (49KB remains, only about 800 or so was used before), and Finder shows the Fusion drive as being 860GB capacity with 837GB used. I still can't repair the disk. And now my Time Machine acts like I'm working on an entirely new computer and says there's not enough room on the drive unless I format my Time Machine drive and start over.
Yeah, TL;DR, but does anybody have any idea how I can get this issue resolved? I wonder if doing the TM restore from my 2009 iMac may have introduced the non-Fusion version of Disk Utilities that doesn't know how to fix my issue.

Yes I have AppleCare.
Before that I've now made a bootable disk and tried to repair the internal drive, but this was not possible.
I have a Time Machine backup, but excluded some temporary folders.
Is there a way to access these folders in case they aren't in a damaged area?
Maybe using "Target Disk mode"?
I've never done this before.
This Mac has no FireWire, but we have an adaptor for Thunderbolt to FireWire - could I connect an older Mac with FireWire using this adaptor for Target Disk Mode?
Many thanks.

Drive Partition causing issues after new hard drive and recovery disks installed

I have an HP Pavilion Media Center PC m7640n running Windows XP Media Center Edition.
My hard drive failed and I had a computer guy install a 1 TB Hard drive as well as additional memory. I purchased the recovery disks and he installed everything for me. I have two issues:
1. After updating to XP Service Pack 3 and all other Windows recommended upgrades the computer deleted all my drivers and would not "plug and play" install anything. I had the computer guy back to fix this--he did get all my drivers to work, but when I plug in anything new for the first time (such as my iPad), I have to go into the device manager and manually update the drivers. The computer doesn't recognize it and automatically prompt me to install it.
2. The hard drive partition defaulted to my C drive being very small and my D drive being large. Since software usually defaults to the C drive for installation, I quickly ran out of space. I had the computer guy back and he programmed something so that everything now defaults to the D drive. Unfortunately all my program files (including Microsoft Office) are still on my C drive including everything I put on my desktop. My C drive is now full.
Here is an example: iTunes shows that it is defaulting to the D drive for anything I load into it. Yet I tried to download the new operating system for my iPad and it said my hard drive was full. When I did a file search to see what files had changed in the last week, it shows iTunes on my C drive (and my D drive). Yet all the files that were "changed" due to my upgrade were defaulting to the C drive, even though in the setting in iTunes it shows it should be saving to the D drive.
D:\Documents and Settings\My Music\iTunes\iTunes Media
Is there an easy way to fix these issues? I've already spent more than I anticipated when I chose to rebuild this computer vs buying a new one. Now I'm regretting the decision and I'd like to try and fix this myself and not pay my computer guy to come back at $90/hour.
Thanks!

Here are the original specs of your computer. The specs state that the original hard drive was 320GB. You have since replaced the factory drive with a 1TB (1000GB) hard drive. The HP recovery routine seems to have issues with hard drives that deviate from the original size. The partition issues you are experiencing may be a result of this. As for the rest of your issues, it sounds like the SP3 install went bad.
If I were you, I would consider reinstalling the OS using your recovery discs by doing a complete "destructive" reinstall/recovery. Afterward, I would post the size of both the c: and d: partitions... and go from there.

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.
See here:
http://support.apple.com/kb/HT5639?viewlocale=en_US&locale=en_US
and here:

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.

To install Windows 8 OS on a new iMac using Boot Camp, what size "partition" should I allocate for Windows on a system with 3TB Fusion drive?

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

How to restore partition layout of my 1TB Fusion Drive?

Hi there,
I purchased a Late 2013 iMac 27" with a 1 TB Fusion Drive. I tried to install Windows 8.1 without Bootcamp. My Installation with Bootcamp didn't work - there was an error stating that Windows Installation was not able to prepare for the next step of the installation - so I partitioned manually via OS X Disk Utility (resizing the Macintosh HD) and tried to install to the unused disk space - okay my mistake. This somehow didn't work either. Now I have the following situation: The Disk Utility shows the following partition layout:
Macintosh HD 779,53 GB
Unused disk space 220,33 GB
I am not able to resize the Macintosh HD to use the unused disk space (original partition layout). There is no option for this. The partition layout option is greyed out. When I try to create a second partition of the unused space and proceed, nothing happens (protocol states preparing to partition: „APPLE HDD ST1000DM003 Media“ - nothing more). The operation will not finish. Next to the partition scheme is the following information (translated from german): "For a new partition layout the whole capacity of the Fusion Drive won't be available." The whole Macintosh HD now has a capacity of 900,52GB (Disk Utility).
What can I do to restore to the original partition layout of my Fusion Drive which had a capacity of about 1,1TB?
Thank you for your help!
Chris

Yes, I think my first attempt was also in EFI mode, this could have resulted in the second EFI part.

Thanks for your help!

Is it possible to partition a 3TB fusion drive?

Hi, i'm a bit of a noob when it comes to the new technology. I searched for the answer, but it didnt quite answer my question.
I have new iMac with a 3TB fusion drive. I would like to create a small *backup* partition where i can create an installer version of mavericks so when i do a clean install, i can select that drive from the bootable disk selection menu and it runs the mavericks installer from that partition, rather than a USB thumb drive. I looked at the recovery mode option however it appears to download a new 5gb installer of mavericks instead of using an already downloaded version of mavericks (updated version).
I dont want to split the SSD/HDD components of the fusion drive so they are seperate, i just want to add a small partition to be partitioned as a mavericks installer drive.
I hope someone can answer if this can work. Thanks in advance

Yes, you can do this. You can partition the drive using Boot Camp Assistant. Then instead of installing Windows, quit the Boot Camp Assistant and then use Disk Utility to reformat the BootCamp partition to Mac OS X Extended.
After you do this, you will have to install Mavericks on the drive. Then after Mavericks is installed, you can then copy the installer over to it. I would also recommend that if you have DiskWarrior, Drive Genius, or TechTool to install them on that partition as well.

Does anyone know what the partitions look like after installing boot camp on a 3T fusion drive

I installed a boot camp partition on a 3T fusion drive. Running disk utility afterward it looks like this.
Is this what it should look like? I understand about the need for bootcamp to create 2 physical drives in core storage in order to install boot camp on a 3T fusion drive but should I see both drives after it is done?
