Trouble creating a third partition in Disk Utility.

Hello, I am fairly new to the Mac as I recently switched from a PC just a few weeks ago. Now you won't be dealing with a "noob" here because I am a power user when it comes to the PC so not too much adjustment has been needed for OS X.
So I Have the MacBook White 13" Early 2009 model (MacBook 5,2). I upgraded it to a 320GB HDD and installed snow leopard the first day I got it. Then I decided that I wanted to create a bootcamp partition and install Windows 7 (Not hard to do when you have Google to provide you with any knowledge you require). Googling is how I and most people learn these days so I have gained quite a lot of experience with OS X for the 3 weeks I've been using it.
Anyway, BootCamp went as smooth as it could get, Windows 7 runs when I boot, Both OS X and Windows 7 Partitions work perfectly.
Now, My desire is to create a third partition of 25GB with Disk utility by shrinking the main OS X partition (BootCamp is at 60.73GB, OS X is at 259GB).
The reason for this partition is to Install OS X Lion Dev preview.
For some reason it is proving impossible to create this partition. The first time I tried, I had a kernel panic, but I was wondering if this may have been because I was simultaneously burning a disc image to a DVD and Creating a third partition on My HDD.
After I restarted, I again attempted to partition. Setting a new Mac OS Extended (Journaled) partition of 25GB on the Main OS X partition. It then began partitioning, trouble is it seemed to completely freeze the UI and I could not do anything other than move my cursor, I thought this was maybe because the hard disk was being partitioned and therefore affecting anything on the disc during the process (Hence the UI Freeze). So I decided to leave this for about half an hour, but I had noticed that it was still in the exact same state, it seems to be getting stuck on the Shrinking phase, which is of course the actual partitioning and shrinking of the Main Partition. I also thought I should check if there was any Hard disk activity going on, as the UI was locked up, I could only listen to the drive, the drive was spinning but the actuator head did not sound like it was reading or writing anything, it was just parked. No activity.
As it seemed to be stuck on "shrinking" forever and the UI was still locked, I forced a shutdown. Both partitions were unchanged as bootcamp and the Main partition seemed to work perfectly. So I tried the process again, this time I tried, and the UI did not lock up but I did receive the error "could not modify partition map because filesystem verification failed". So I did some googling again and arrived at the conclusion that I need to repair the disk. So I checked this in disk utility by verifying the disk, and Lo and Behold, It reported that the disk needed repairing. Now at the moment I didn't have my OS X install disk, so after another visit to google I found that using fsck -yf works exactly the same in single user mode and repairs the Disk. After the repair, I booted into OS X again and tried to partition again... And the same happened, UI Freeze, No error report, Just a pure freeze at "shrinking". I Cannot find a way around this and it's beginning to frustrate me. I attempted a few more times, force shuting down, Repairing, then trying to partition, But I'm getting Nowhere.
I'd be very thankful if you can help me solve this problem.
Thank You
Jordan L. Sutton.

Thank you for that link, with a little reading I did find that I may not have enough free contigous space on my Hard drive. I found that this could be fixed with a defrag. Now I know Macs should not need defragmenting due to their great extended format which manages this automatically. But using iDefrag, a software available for defragmenting a Mac hard drive. This seemed to free up contigous space and after a defrag, I was able to try again with creating a third 25GB partition, and it worked like a charm. I'm not sure what the core issue was but even though Macs should never need defraging, it did work.
Thank you.

Can't create a 3rd partition in Disk Utility

Long story short I have used Boot Camp to get Windows, so I have 2 partitions. But, I need to create another partition to install another copy of Windows on it, but Disk Utility has grayed out the '+' to allow me to create a new partition. All I can do is delete the 'BOOTCAMP' partition which I don't want to do. I tried another way by going into Boot Camp Assistant and installing Windows through there. I have a bootable USB drive and I know how to install it, all that's stopping me is the partition issue.
Any ideas?
If it helps, I'm using a Late 2013 MacBook Pro with a 15" Retina Display, 2.5 GHz, 512 GB SSD, 16 GB RAM and a NVIDIA GT 750 M.
Thank you for your help

Good thing to mention that, I forgot to do that.
Unfortunately it did not help.. The screen to remove the existing Boot Camp partition does not pop up, it just tries to create the new Boot Camp partition.
The partition I'm trying to create it 150GB. The 50GB mentioned above was on the stock Fujitsu 250GB disk.
Edit:
I'm actually trying to avoid using Boot Camp Assistant.. I became to dislike the utility due to problems creating a partition on my previous HD.
I would like to create a partition using Disk Utility and then install Windows 7 by selecting that DVD to boot from.
Thank you for the tip though, I'll post it there as well!

How to create a third partition without messing up Boot Camp partition?

I have been running a dual-partition Boot Camp setup (with Mac OS 10.5 and Vista) on my Macbook Pro with no hitches for the past year or so. Recently, I have decided that I want to create a third partition to boot into Windows XP. Of course, Boot Camp doesn't let me do this, so I am trying to do it manually by resizing my Mac OS partition and devoting the remaining space to a new partition. However, when I try to resize my Mac OS partition in Disk Utility, it warns me that "Changing the partition map may make this disk unbootable using Windows."
So I am wondering: is there any way for me to create a new Windows partition without messing up my preexisting Boot Camp setup?

I found this blog post shortly after the first BootCamp beta was out. I successfully split mine into three partitions per the instructions. However, since Leopard now lets you live partition your disk, you can probably do the partitioning via Disk Utility instead of using diskutil in Terminal.

Resized partition using Disk Utility and now Windows 7 will not boot

Hi,
Hopefully someone can help me!!
I had previously used Boot Camp to install Windows 7. However, I later realised I had not given myself anywhere near enough disk space as I started using Windows for things I hadn't originally planned on using it for.
Anyway, long story short, to solve the problem I uninstalled some applications on my Mac OSX and used Disk Utility to decrease the size of my Mac partition. My plan was then to reboot to Windows and use a Windows application to increase the size of the Windows partition. However - I coudln't even get that far.
Upon decreasing the size of my Mac partition (succesfully) I restarted my Mac in order to boot to Windows. However, I was greeted with a message along the lines of "unable to boot to Windows please insert boot disk and press any key" (I can't remember the exact message).
I was wondering if anyone knows of any way to restore my Windows partition, retaining all of my previously saved files on my Windows disk. It's probably a long shot, but the thought of losing everything I have been working on for the last few months is a sickening one.
What does give me a bit of hope is that, if I click Boot Camp it seems to recognise that Windows 7 is installed as the option that appears is to uninstall it.
Furthermore, if I view partitions in Disk Utility, a "DISK0S4" is listed. However, it's only at 20gb - if this WAS my BootCamp partition previously, it was originally at something around 60gb (I think - either way, definitely bigger than 20gb!).
On top of this, my current Macintosh HD parition is at 260gb and with the DISK0S4 partition at 20.21gb, there seems to be some space missing... I'm hoping this is the files I've been working on over the last few months!
Anyway, I've done some searching on the net and it *seems* that GPT fdisk *might* be my savour. I've downloaded it but have no idea how to use it and don't plan on playing about with it as I could no doubt do some real damage. If it is likely to solve my problem however, I'm certainly more than capable of being walked through what I need to do.
Please help!

Hi Christopher,
I also have problems with Windows rebooting after partition resize trying to reduce Mac side and increase Windows side. I do not see the BootCamp partition labelled as such while running disk utility. The Windows partition shows up when I boot up while pressing the ALT key. However, when I try to run Windows, it says " error loading operatig system".
I also followed instruction and went through to run gdisk successfully. Results towards the end.
What can be done? Windows still does not boot and It shows ? Suspicious MBR at sector 0.

I erased my windows partition using disk utility then realized I should have used boot camp, because now I can't resize the original partition and seem to be stuck with a ghost unusable space. Boot Camp now doesn't give me the option to install or remove windows partition.

Hi, Ralph,
The problem is that I did erase the partition, using disk utility, but I can't go back to my original disk size pre-partition, as disk utility won't let me do it and gives the message "Couldn’t modify partition map because file system verification failed." When I try to use Boot Camp Assistant it won't let me select the third option to remove windows.

I can't delete partition in disk utility, it keeps telling me that "the changes are too small"

I previously split my disk into two different disks, however I want to combine them together again, yet i was unable to delete the second partition. I can't delete partition in disk utility, it keeps telling me that "the changes are too small"
Plz help!!!!!!

Make at least two complete backups of all your data. Boot from another drive and partition this one as desired. Restore the data.

How can you change the primary partition in Disk Utility?

I have made another partition using Disk Utility to install Snow Leopard. On my main partition Lion is installed but when i boot into Snow Leopard and try to delete the Lion partition it comes with an error "This operation requires a newer version of Mac OS X for this disk". I tried deleting the partition from Recovery HD but it says it couldn't unmount the disk.
Is this because Lion is the main partition, can you even delete the main partition?
And if I do delete the main partition will i be able to move the Snow Leopard partition "upwards" in Disk Utility?

1) First of all what is GUID.
It's the "partition map scheme" Apple uses so your firmware knows what is what on your boot drive, what partitions there are and what format they contain.
2) Secondly, would I just be able to make a new image in disk utility and use that instead of an external hard drive?
No, you need something to boot off of and remove all data off the internal drive that's going to be reformatted with a new parttion, that's why you use the free Carbon Copy Cloner, it does both in one shot and it "blesses" the drive to make it bootable.
3) When I use Carbon Copy cloner will it only copy Snow Leopard Installation or all of my files also?
It copies everything in your Snow Leopard partition to the external drive, files, programs the OS everything except whats in the Trash.
4) In your 8th step you mentioned repairing permissions on both. Both of what?
Both drives, the internal and the external clone in Disk Utility (ignore the long list that appears)
It's a safety check to make sure your permissions are set back to original settings, I think the newer version of CCC now does this, but I havent' checked, doesn't hurt to do it again.
5) If you still feel like typing can you tell me how long this whole process might take?
Formatting a external drive
You should Erase with Zero option first, that will take a hour per 500GB
Formatting shoud be rather fast, a few minutes.
Cloning Snow Leopard to the external drive should take about a hour per 500GB
Formatting the internal drive a zero erase first for safety should take another hour per 500GB
Reverse cloning Snow Leopard back onto the internal drive should take another hour per 500GB
Good thing about it, it's pretty much all ciick and go watch TV while it works.
I was actually planning to make a Genius Bar appointment to fix it, by the way does that cost much?
No idea, but you don't have to pay if you get a external drive for $70 or so, CCC is free.
You get to keep the external drive and use it later for cloning as hard drives die all the time, the clone would get you back to using the computer.

Partition with Disk Utility?

I just got a 500gb external drive that I want to partition. Disk Utility is supposed to be able to do this. The help file says "Click Partition" in the Disk Utility window. I see nothing in the window with "Partition" on it. A screen shot I've seen (from LaCie's hard drive manual) shows five buttons across the top of the window: First Aid, Erase, Partition, Raid, Restore, but my Disk Utility only has 4 buttons. The "Partition" button is not there.
Any ideas what's up? This is crazy. What am I missing?
I've clicked on the external drive icon along the left column but nothing pertaining to partitioning shows up.

That is because you have your boot volume selected in the left hand column, select the Hard drive itself, the one with the Manufactory ID number. It should be at the very top.

How to recover after performing an 'Erase' and then 'Partition' within Disk Utility of an External USB drive?

Hi - I accidently ran an 'Erase' and then 'Partition' within Disk Utility of an External USB drive (meant to run it against another drive that was plugged in). Does anyone have any suggestions on if it is possible to recover from this? It has all my family photos on it and my backup is a few months old :-(
I tried running Stellar Phoenix Mac Data Recovery but it found what looks like basic mac folder structure (probably from the first erase). I think what messed me up was that I rain the repartition which formats the drive a 2nd time! Any help is truly appreciated!
thank you,
-Steve

Hello RalphR_MI,
Take a look at this page, which lists several articles. Please let me know if any of these help you restore your backup.

Cannot read partition created by Boot Camp in Disk Utility

Ok, so in trying to get a larger Boot Camp drive, I used disk utility to make a back up og my previous drive onto USB, and then removed the Boot Camp drive from OSX. This afternoon, I tried using Boot Camp Assistant to create a new partition to install windows onto, hoping to restore from the disk image on the USB drive.
HOWEVER, when restarting the computer when Boot Camp Asst. told me to, and it booted to WInXP sp2 disk, I can see 3 partitions on my drive. 1 partition being most of the 160g drive, 2nd partition being 116g of the mac drive, and the 35g of the 3rd partition (what I asked Boot camp to make) However, it doesn't say boot camp partition. I cannot install XP onto any of the partitions I see in the startup disk.
After spending nearly two hours on the phone with a very nice and helpful tech rep from Apple, my cell phone died, leaving us knowing that there is more space reportedly being used on my Mac HD than i have folders using space (only using about 73gigs of space before any of this partition work, now reports using 116 GB). I went back into the XP disk and deleted the 3rd partition, and now there is no gain in space on my Mac HD. We're re-verified and repaired disk permissions, and used the Leopard disk to repair the disk itself. Restored from Time Machine, and still no regained HD space.
Essentially I'm missing 35G of hard drive space now, and I can't install Windows.
I can only see the Mac HD partition on my hard drive. Anyone have a suggestion?!?!

Reinstall Leopard, but first use the Leopard install DVD Disk Utility to reformat the HD to one partition. See:
http://docs.info.apple.com/article.html?path=Mac/10.4/en/mh14.html
It's for Tiger, but applies for Leopard as well.

Partition layout greyed out – not possible to create a third partition

Hi all,
Being in need of a new laptop, I bought myself a Macbook Pro retina, 13inch, 512gb SSD last weekend. I’ve been a windows user for almost 20 years now, with occasional exploits into Unix/Linux, but I’ve had it in mind to try out OS X for quite a while. I like the hardware and the design of the Macbook Pro and the fact that Boot camp promised to make dual booting into win7 a walk in the park, lead me to just try it out. However…
When I tried running boot camp (based on creating bootable USB’s):
ISO number 1 first didn’t get recognized by boot camp
Omitting the bootable USB creation by boot camp, downloading the drivers on a separate USB stick and using my own bootable USB lead boot camp to state that it didn’t recognize a windows install disk (even though the USB is bootable and does work)
Creating a full new ISO and using that one to create a bootable USB by boot camp worked, but gave an error during the copying of the files (can’t create USB, error during copying windows installation files)
Making a new image of that ISO within OS X to avoid compatibility issues gave the same error
Using another USB stick gave the same error
Unmounting the image still gave the same error
At that point I gave up on wanting to use boot camp and I decided to do the install myself. Going to disk utility to create new partitions triggered a new issue:
Via the “+”-sign, I can create a second partition on my drive. I can name that partition, format it any way I want and make it as big as I want.
After doing that, the “-“-sign is available to remove that partition again and to merge all back into one big HFS partition.
The tool doesn’t allow me to create 3 partitions though. The partition layout box is greyed out and fixed on “current”, and after the second partition is created, I can create a third one
Rebooting and doing disk utility via CMD+R gives the same issue.
I looked on the internet, found people with similar issues, but until now no real solution (unless a “boot via USB and partition from there”-solution, which I didn’t try yet).
Why doesn’t the system allow me to create 3 partitions?
What can I do to still create 3 partitions?
Is working via a bootable OS X USB really the only way to do this?

LVM is not cluster aware and does not support write barriers, both of which are important for a filesystem that is used for storing file-backed disk images.

Can't boot into Windows after splitting Mac partition with Disk Utility

Hi everyone,
I installed Windows 8 with BOOTCAMP, creating a large 871 GB partition with a smaller 127 GB partition for Windows. After installing Windows, I then went back to Disk Utility to shrink the Mac partition and add two new partitions, one for storage and another blank, hoping to use it to install Linux into one day.
I did that, and now Windows doesn't boot. A Windows blue screen tells me I need to use the Windows DVD to repair it.
I tried to use Disk Utility to delete the two new partitions I made and grow the Mac partition back to the max size of 871 GB. But it doesn't let me do this. The Disk Utility log doesn't report an error and thinks it worked but the partition stays the same size. However if I make the partition a little smaller, like 870 GB then it works. I'm wondering if the Recovery partition is hiding there and preventing me from fully expanding the Mac partition.
What can I do?

Okay, the code I typed didn't display properly in the forum. Let me try again.
Here's what I get when I type

Kappy,
I can boot into OS X just fine so if possible, I'd like to avoid reformatting everything. If you know of a way I can add more than 2 partitions with OS X and Boot Camp, please let me know. As far as I know, rEFInd can recognize more than two partitions, but I don't think it can edit partitions on a GPT / hybrid MBR system. Or am I wrong?

Unable to create "filename.dmg" (error -60008) {Disk Utility Problem}

Hi:
I’ve used Disk Utilities awesome capabilities many times, but am now running into my first real problem.
I am trying to create a 100 GB new blank disk image, using the “Mac OS Extended (Journaled) option for format, 256-bit AES encryption, a single partition-Apple Partition Map, and Image Format as read/write disk image.
When I implement this, it asks for the AES password then repeatedly crashes, albeit in slightly different ways each time. The most informative was a Unable to create “filename.dmg” (error -60008) message. I can’t find anything explanatory about this in Google
I’m wondering if this has something to do with my upgrade to Lion (OS 10.7.4) yesterday from Snow Leopard.
This error occurs on both my home and work iMacs. It seems to reliably occur about 1/2 way through typing in my password. The error occurs whether I use 128 or 256 AES encryption.
There is more than adequate space on the hard drive I am attempting to place this image on. Disk Utility is version 12.1.1 (353) and all is running on a 2.66 GHz Intel Core i5 iMac.
Any advice would be greatly appreciated! Thank you
PS: This is a duplicate post from the OS Lion forums ( https://discussions.apple.com/message/18410534#18410534 ), but since a) it occurs on both my Intel iMacs, b) I totally rely on Disk Utility's capabilities, so this loss with the Lion upgrade really hurts, and c) we've had no luck in the Lion forums, we're hoping someone here has seen this issue and can help. Much appreciated.

Hello, I believe that's an authentication error, thinks your not an admin account. Might try this...
Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, move this folder to the Desktop for now...
/Users/YourUserName/Library/Preferences/ByHost /
reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
