OS X :: Unable To Create The Necessary Partition In Disk Utility
Nov 19, 2009
I have a Mac Mini and on the internal drive I have Snow Leopard installed on the first partition and I'd like to install Snow Leopard Server on the same drive on another partition (I'm new to Mac, this is my only machine and my only drive, and this is only for testing purposes, so don't bother with stupid questions about why etc).
The problem I have is that I can't seem to create the necessary partition in Disk Utility. I have shrinken the Snow Leopard partition to get some free space and I've created a second partition for Server but for some reason I can't choose the options button to select GUID. The button is grayed out, see attached image.
What am I doing wrong? Or is it not possible to have two OS partitions on the same internal drive?

First some background info. I recently purchased a 1TB hard drive for my 13" MBP, and I am about to do a clean install of OSX 10.6 and Win7 64bit on separate partitions.
And I want to setup the partitions before I install using Disk Utility. The reason for this is because I'm under the assumption that when creating a NTFS partition its better for the disk to be blank so it can put the MFT(Master file table) and MFT Mirror wherever it wants instead of some random spot on the disk (that way disk writes will be faster). The MFT thing was true when converting a FAT32 disk to NTFS. Nativity formatted NTFS disks were always faster then ones converted from FAT32, because the MFT was spread out instead of at the start of the disk.
I'm worried that installing OSX and then using the bootcamp utility will cause the MFT on my NTFS partition to end up in a un-optimal place and disk Reads/Writes will be slower.
Ok, so here's my questions.
1.) Should I be using a GUID Partition Table or Master Boot Record(Remember OSX 10.6 and Win7)?
2.) Should I use Disk Utility to Create a the OSX partition and then leave the second partition as Free Space? / Or should I use a third party utility and make the OSX partition and the NTFS partition at the same time?
3.) If I do create the partitions Manualy, will bootcamp still work correctly?
4.) Should I Use Journaled or Case-Sensitive Journaled on my OSX partition?
I know all of the questions were stupid, but there isn't any info on the web about it.

I have installed 2x Intel X-25M Gen2 (SSDSA2MH160G2C1) 160GB SSDs in RAID 0 (striped) in my 17" uMBP. Second SSD was installed using a MCE Optibay in place of CD-ROM. I used the OSX Disk Utility to create the stripe partion with no problems. I currently have 10.5.8 loaded and will be loading 10.6.0 tonight and doing some simple GeekBench benchmarks.

I have a 3 TB disk that I used for video files that I now want to use for backup. So I wanted to erase and partition the drive to wipe it clean. So after going into Disk Utility and "trying" to erase and partition the drive, it now only shows the drive and no volumes.I cannot create or partition volumes. I tried verifying and repairing the disc but that didn't do anything. The only buttons available are Verify, Info and Burn. What do I do to use the drive again?

I have a Lacie 1TB external drive. I'm trying to create another partition on it using Disk Utility so that I can use one of the partitions for Time Machine. When I go to add another partition, or even just resize the existing one, I get an error saying drive must be HPFS+ with Journaling enabled. It is. I've seen reference to this error in searches, but have not found a solution. Is there a fix for this, or another tool that I can use to re-partition my drive without wiping out existing partition? I have about 450GB worth of data on the drive that I might be able to store somewhere else temporarily, I would just prefer not to have to go through that....

I can boot into bootcamp with no problems. I have been wanting to be able to open the bootcamp in Parallels. Here is the issue:
1. The partition 'disk0s3' is greyed out in Disk Utility. It is not mounted. Mounting does nothing.
2. For reference, the Windows 7 is formatted as NTFS. It is a Windows 7 64-bit install
3. Verify disk does the following:
Verifying volume "disk0s3" ** /dev/disk0s3
Invalid BS_jmpBoot in boot block: efbbbf
Error: This disk needs to be repaired. Click Repair Disk.
4. repairing does the following:
Verify and Repair volume "disk0s3" ** /dev/disk0s3
Invalid BS_jmpBoot in boot block: efbbbf
Volume repair complete.Updating boot support partitions for the volume as required.Error: Disk Utility can"t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
I have stuff on the Windows partition that I don't want deleted. I'm really stuck on this -obviously, I can just continue to boot into bootcamp, I just would rather open it from Parallels. I'm not sure what or if I made some mistake in setting up Bootcamp, I thought I followed the directions to that. I do know I formatted the partition as NTFS during the install - as I think Windows 7 requires it. I have tried installing NTFS-3G - it is installed, but didn't do any good when trying to mount the drive.

I recently made a clone of my Windows XP Pro SP3 installation (its roughly about 14GB according to Finder/WinClone) so i made a 80GB partition on my 320GB drive and it gives me this error message:
the WinClone came from a 500GB internal drive and ive gotten winclone images to restore to a MBP before but not sure why its giving me this error code, anyway to restore the image to the new partition (which was created with Bootcamp) as i no longer have access to the old machine it was running on.

I have a 2TB Western Digital My Book Studio FW800 external that has 5 partitions, connected to my 2011 iMac. I had help doing the partitions and don't really remember the reasoning, but one is just for my SuperDuper! backup, one is Miscellaneous, one for movie clips off my camcorder, one for misc scanned photo's and one for my genealogy research. I back up using Time Machine to a Time Capsule and also to this WD hard drive with SuperDuper!
Recently I'm getting a pop up message that "Mac OS X can't repair the disk "Genealogy"'. And it needs to be reformatted. It's become a read only disk. When I look in Disk Utility it shows all the partitions as "Mac OS Extended (Journaled)" EXCEPT for the one in question. I also noticed that there are a lot of files with "date created" being the same date in 1969! These files may be letters I've written or photo's I added to that partition within the last few years.
I think I have to completely reformat the entire external hard drive to repair this, but I want to make sure. Because it's going to be a major hassle backing it all up to another external (having to get one first) and then figuring out how to make the files that have turned "read only" in that one partition, back to their original state! Does this sound right, that I have to reformat the entire external hard drive? And how do I get the read-only files back to their original state.
Info:
iMac, Mac OS X (10.7.3)

I had windows vista installed but suddenly the audio decided to become faulty, after spending a day trying to fix it i realized I have a windows 7 install disc so i might as well just replace vista with windows 7. I didnt take care of vista or ever register it so it became quite a task to upgrade so i just deleted the partition and went to create a new one and just do a full install of windows 7.
I made the partition but the wrong format, so i removed it through boot camp assistant and created another, except now it keeps giving me the "back up the disk and use disk utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using boot camp assistant again" Now, I'd love to do this, except I have no idea what I'm doing and WHY this error has occured. After becoming frustrated I switched from my imac to my macbook pro and received the same error when trying to create a partition. So any help on exactly what I need to do would be a HUGE help. I only use windows for music production (I know, seems backwards, but I use Sony Acid and FL Studio so I'm stuck with Windows)

I have run the Disk Utility verify function against my system partition. It tells me there are minor issues that need fixing up and I should run the repair disk function, by booting using Command-R and using the Disk Utility to repair the drive.Problem is, when I boot using Command-R and select Disk Utility the partition is shown greyed out and the Verify and Repair options do not work.I think this could be because the partition is encrypted. The utility does not offer me the chance to unlock the partition with my passphrase.How can I repair the filesystem errors on this partition?

My new 2010 hexacore Mac will have 24G memory, an OWC Extreme Pro 120G SSD (positioned in the lower optical bay) and four 2TB WD RE4 drives. I'll use my old Synology 209 NAS (two 1TB WD Green Raid 1 drives) for TM backups over 1000Mbps Ethernet. Yes, I'll need to upgrade to a larger NAS very soon. This will be my first Mac Pro (have MBPs and iMac) and will be used for web design and development (mostly Adobe CS5 products).
The SSD will be used for boot and application files. I plan to use Disk Utility to create a 1+0 Raid array for data files. For a Scratch disk, should I:
1) create a partition on the 1+0 Raid Array for Scratch
2) partition a chunk of the SSD for Scratch
3) attach a spare external 2.5" WD drive via Firewire 800 for Scratch
Based on my reading, it seems that option 1 makes the most sense but I'm not entirely sure if you can partition a 1+0 array with Disk Utility. I'm pretty sure option 3 is quite silly but wanted to toss out the idea. Lastly, are there any generic recommendations on scratch volume sizing?

I have a 640GB external USB hard drive that I use for time machine currently. I would like to go in and add a partition to load movies to and plug it into my PS3. Can I use disk utility to create a new partition without erasing the stuff already on the disk?
And then is it possible to format a partition larger than 32GB as FAT?

After my macbook hard drive kindly failed on me, I ordered a new Seagate Momentus 5400.5, 320gb hard drive. I popped that sucker in this afternoon and began to start up my macbook with the OS X disc 1. Everything was going smoothly, except that it can't find the hard drive. It is recognized under my disk utility, but when I click to partition it, select options, select GUID, click 'OK', I can neither Name it 'Macintosh HD' or do anything else.
I can't proceed with anything because when it asks me to select a HD, the HD does not show up. Again, everything works except that the hard drive is not found. I pulled the hard drive out. Made sure the screws were alright. Made sure everything was all snuggly, and yet it still won't work.

Tried to create a bootable clone using Disk Utility & got this:“Restore Failure, Recovery partition restores can only be done on GPT partition maps.”I may need to purchase Carbon Copy Cloner ($40) or Super Duper ($28).I had been using my free CCC v. 3.4.7 to make clones of OS X 10.6.8 but now I upgraded to OS X 10.9.4 & got message that CCC not compatible with Mavericks unless I buy the CCC v. 3.5.6.I read several places that DU can do back up clones same as CCC or SD!I launched DU from recovery system, selected Mac HD as source & my XHD as destination. Both are formatted Max OS Extended (Journaled)So, what am I doing wrong?Also, what advantages, if any, are there in using CCC or SD instead of the free DU?

I own an iMac with a 250 GB HDD along with a Macbook that originally had a 120 GB HDD. So when I purchased my 1 TB external HDD this summer, I partitioned the external so I could back up both my iMac and Macbook via Time Machine. Seeing how small the Macbook HDD was, I allocated roughly 300 GB of my external to it, with the iMac getting the rest.

I'm trying to partition my hard drive. It's currently one whole 160 GB unit. I want to split it into a 135 GB partition and a 25 GB partition.
Currently Used Disk Space: 95.10 GB
Currently Free Disk Space: 53.51 GB
However, whenever I try to create the 25 GB partition in Disk Utility (formatted as Mac OS Extended - Journaled) it gives me an error message:
And here's a screenshot of my hard drive's info:

Originally I had 2 partitions on the internal 500gb hd in my MBP, one was 455gb the other was 10gb that I used to mess around on. I do not remember what format the small partition was in last, it may have been FAT32. I wanted to delete the small partition and consolidate into one partition. My OSX partition is formatted macos extended. I went to Disk Utility and deleted the small partition by selecting it and clicking "-." There was grey space where the partition used to be. No problems here. Most of the options in Disk Utility are greyed-out.
I cannot select a different partition scheme. When I try to resize the partition either by dragging it to cover the grey space or by manually typing in a larger size, there is no way to apply the changes. The "Apply" button is continually greyed-out (See Image). If I try to resize the partition and then close the window, Disk Utility alerts me that I have an operation in progress and that unsaved changes will be lost. Disk Utility is not letting me resize my main OSX Partition, it appears that I do not have appropriate permissions to make this change - I am the only user/admin of this machine.

I having trouble resizing an external harddrive of mine. It is a 500gb Lacie drive, and inside it has two partitions: time machine (250gb) and my stuff (250gb). I want to make time machine 150gb and make My Stuff occupy the remaining space. However, when I enter Disk utility, there is no dot between the partitions that I can drag. When I pull the corner, the disk gets smaller, but after resizing there is still a blue rectangle outlining where the old disk was. The partition "time machine" is used for time machine backups, but I have deactivated backups in Preferences, and Time Machine is currently "off". I have included an image for clarification. How can I resize the partitions the way I want them?

Two days ago my computer died and I haven't been able to get past the Apple screen since. I've tried starting in Safe mode, etc. that did not work. I just started up using my installation disk and got into Disk Utility. It says it cannot repair the disk and that I should back up as many files as possible and reformat the disk. How am I supposed to back up if I can't start up? I am currently creating a new image of the HD to an external drive but my question is if Disk Utility couldn't repair the disk, with the external drive copy also be problematic? How can I tell before I reformat the whole thing and start over?

i am trying to format a brand new 120 GB hard drive via an external USB 2.0 enclosure. About 25 minutes ago, I selected the "erase" option and slected the Mac OS Extended (Journal) Volume format. For the last 25 minutes, disk utility has been saying that it's creating a partition map. It's doing nothing.
I have reason to believe my enclosure may be faulty. (I had a similar problem on an old hard disk and thought that the problem was with the disk; now I know.) I need to know: How do I disconnect/eject the hard disk without damaging it? The eject option in Disk Utility is grayed out. If I attempt to quit Disk Utility I get a warning telling me I could leave my disk inoperable.

I installed Ubuntu on my iMac, and it made 2 new partitions: DISK0S3 and Linux Swap. Here's what my disk utlity looks like: When I try to remove Linux Swap, it says that the partition (map is too small.

I would like to know the difference between the options 'erase' and partition' in disk utility. Under 'erase' there are several options: under 'security options' there are 4 options: don't erase data, zero out data, 7-pass erase and 35-pass erase.

I just bought a 1TB Lacie d2 Quadra and want to partition it in 2 partitions. As said in the instructions, if you want more than 32 GB on my "PC" partition I need to use Mac's disk utility. The thing is I don't have the option to partition in NTFS, only MAC OS extended (journaled, etc..) and FAT32. But I need a lot more than 32 GB for my PC stuff. Now how can I do that? I need to backup some stuff from my Windows XP (bootcamp) really soon! And I want to be able to plug it in another PC and be able to transfer both ways. How can I get the NTFS partition option with disk utility? or is there other softwares for that? In all what I want is about 500 GB for MAC and 500 GB for PC (NTFS)!

First off I am new to Mac's and I am trying to repartition my harddrive. i did it once before and was successful and when i tried to adjust the size, windows kept getting errors.
On the advice of my friend he told me to completely wipe out my machine and reinstall Mac OS 10.4. I have since reinstalled SL 10.4 and downloaded bootcamp. However, I do not see a boot icon in my applications or utilities folder, but I do see a disk utilities icon.
When I click that and click the only hard drive that is there and try and partition it, the slide bar will not work for me to divide the hard drive into the size i want and none of the fields or dropdown boxes will work.

I just restore my Mac OS to a single partition and then I tried re-partitioning but it's giving me an error.
I've tried several times, tried using different sizes every time. My HD's capacity is 250GB, and I've got 108.95GB free. So I am sure that making a new partition of 35 - 40 GB is not a big deal. I also tried using Disk Utility, both from the Mac OS install disc and while using the Mac OS itself, but it keeps giving me this error. I do not want to format my Macintosh HD's partition because I don't have an external HDD on me at the moment so I will not be able to back up. I have a lot of important data that can not be deleted.

I installed Ubuntu on my Macbook but it didn't really work for me so I deleted it. I used Disk Utility to delete the Ubuntu partition, but when I want to delete a Linux-swap partition I made while installing Ubuntu nothing happens. I press the minus button and it will delete it. But after deleting it just stays there, and I can't change the partition in any way. How can I delete the partition?
