Intel Mac :: Resize Existing Partition & Creating A Second One On Lion?
Apr 6, 2012
This question concerns the new mid-2011 27" iMac I haven't used yet The internal HD's size is 1TB. Before I start using it, I'd like to:
1. resize the exiting partition (containing Mac OS X Lion) in order to make it smaller (about 100GB)
2. create a new partition in the remaining space. I would use as a data repository (like an external Thunderbolt hard disk).
Info:iMac, Mac OS X (10.7.3), mid-2011 27" iMac

i had my hard drive partitioned in 2 partitions: my lion one and my bootcamp one like this:but as I started installing things in my bootcamp partition i realized i needed more space, so i tried to resize my macintosh hd to a smaller size to enlarge my bootcamp partition, but after i did that and realized I couldn't resize my bootcamp partition with disk utility so i though "well ill just resize my macintosh hd back and that will be it, like i did several times before" but the thing is that disk utility wont let me do so, so now it looks like this:
I have 32gb of unused space i have tried with different things. I have tried with the debug option in the disk utility by tipping "defaults write com.apple.DiskUtility DUDebugMenuEnabled 1" into terminal and mounting my recovery HD and resizing my macintosh hd but it didnt work I have IPartition 3.4.0 in Lion but i cant get it to work because my partitions are from where sytem boots.
ive tried making a start up pendrive but it's a literally never ending process and I also tried making a start up dvd with the 3 different options: when i hit the download template half way to finishing the download says an error has occured and tells me to try again, so i tried with instalation media but it keeps serching and serching without finding the templates. and when i hit the "use existing templates this happens:
i have restarted my mac but the problem remains. i dont know why this is happening because i have had up to 3 partitions with 3 different OS X running perfectly and when I erased the 2 OS X i didnt wanted I could resize my lion partition without any problem. so what I would like to do is in first instance to resize my bootcamp partition and make it bigger cause I need to install more stuff. i have seen many posts in which the say to run the Recovery HD on the free space left but my partition is smaller than my lion one so i guess i wont be able to do that?
summing it up:
1) i would like to make my bootcamp partition bigger, in case of that no being possible i would like to
2) make my Lion partition (macintosh hd) bigger filling those 32 gb of free space?

This is not as simple as the question implies, I had created a partition because of my account/hard drive/whatever screwing up (its a long story). In the end, I have a partition so that I have 2 half sized drives. But I deleted the old, damaged partition and now I just have my current one with half taken up by 'free space'. Here is a screenshot of what I'm presented with: [URL]. My issue is that I cant resize my hard drive partition even though there's loads of space. So my 500GB drive has a 250GB partition and then 250GB of free space that I cant use!

The picture above is evidence of my self-corrupting OS. Those 3 problems are the same every single time I boot my computer. I have done countless re-installs of OS X Lion, even bought a new hard drive and did a clean install. Because of the self-corruption, I cant resize or partition my drive for Windows, with Boot Camp giving me a generic "An error has occurred. Format your disk and re-install Mac OS X" (Partitioning failed so I never wiped).

Up until recently, I had my MacBook Pro's hard drive in 3 partitions: 2 with Mac OS X, and one as a Bootcamp partition. I recently decided that I no longer needed to Mac OS X partitions, so after backing up all the files in one of the partitions I went into Disk Utility and deleted that partition, hoping I could expand the other one to take the free space. Unfortunately, now I have this area listed as "free space," and while I can make another partition in that space, I can't expand my existing partition to take advantage of it. Is there a way for me to get this space back, or perhaps merge 2 partitions together? I'm just afraid of losing ~400GB of space.

I recently bought my mother a Macbook. It was a store display one but she had no problems with that. Anyways when we first boot it up I noticed that on the desktop there is a Time Machine disk. So I openMacintosh HD that there is only 17 gbs free out of 33 gb, so I check System Profiler to see if there is a smaller hd in there but the it says that the hd is 150 gb.
So I'm wondering how to delete the time machine partition and resize the Macintosh HD partition so I can give her the most space she can get.

I created a logo in Pages using a few text box, some text and various shapes and colors. I created it at the largest size I think I'll be using it at (quite large, a few feet across) and now I want to use it in several other, smaller instances. I grouped it all together, but when I resize the box, the type stays the same size and so everything gets out of place. Is there a way in Pages to save an object such as I've created here, and be able to resize it in correct proportions etc, so that I can use it in various sizes etc?

Basically the user is running 10.6.5 and has removed their Boot Camp partition, but is unable to grow their partition into the newly empty space.

So here the deal. I have a single hard drive in my MacBook Pro. Its made up into 2 partitions (one for os x and the other for data). I want to make the OS X partition into 2 separate partitions (so I'll have a total of 3) without erasing any data. I want to use that new partition to install windows. When I select the OS X partition, and set it to format at NTFS, it says the size cannot support the filesystem (25GB in this case). What size does it have to be then? Or should I format as FAT32?
I know FAT32 has a 4GB file size limit so I don't want to do that because I want to install some games on the Windows partition. How should I go about doing this?

I currently have 3 partitions - 50GB OS X (HFS+); 70GB Vista (NTFS); and the rest is in Data (HFS+). I want to shrink Vista's partition by 20GB and add that space to my Data drive. However, OS X can't seem to touch Vista's partition; and when I try to shrink Vista's partition within Vista, it puts the space after Vista's drive (but I need it before Vista's partition).

I'm in Disk Utility and I can see that the Leopard partition takes up about half of the total disk space. There is nothing else on the disk, the partition just isn't that big. I wanted to expand the partition to fill up the whole disk but I get an error that the partition map is too small or something.

My MacBook Air runs OS X 10.9.3. The HD storage is 256GB. I created windows 7 partition (150GB) by BootCamp when first use. So for OS X, there is 100GB left.Today I add a new partition of 30GB size from Macintosh HD to test installing OS X 10.10 Yosemite DP. The installation was successful, but the new look of OS, including Dock, Font, et al, is awful. I am disappointed and then erase the test partition in 10.9.3.
Naturally I wanted the 30GB back to 10.9.3, and used Disk Utility to resize the Macintosh HD back to 100GB.However, it simply doesn't work, the size of HD remains 70GB, no error message showed. I am sure I followed the support doument to resize partition.

I have a MBP 2.4 SR and windows XP 32bit is installed on Boot Camp... I would like to know if it's possible to resize the OSX partition to make it bigger... Or do I have to uninstall windows and install it again...? Because I really need the space...
Btw, is there a program that can tell me what optional leopard software (printer drivers etc.) are installed?

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.

Well when I bought my Mac I said "O I bet I'll still use Windows a TON for various tasks." So I made a 100GB Partition for Windows. Now I'm realizing how dumb that was because I only boot into Windows once a month now, and I have only used about 10GB of that Windows Partition. So I have about 90GB free on that partition. Back on the OSX disk I only have 3GB free, and I need space. So, can I make the Windows partition smaller, or do I have to completely wipe it?

I have been experiencing recurrent app crashes on my Macbook 3,1 running 10.6.1 for the past few weeks. Turns out the error was Kernal protection failures with apps like iTunes (latest version), Grab, Carbon Copy Cloner and Super Duper. One recent report of a failure is at the bottom of this post. Thinking my 10.6.1 install had become corrupted (I had done an upgrade to SL), I decided to partition my 320 gig drive and do a erase and install on the new partition. My current install takes up 130gigs. I have tried using Disk Utility to make a new partition of 130, then 120 then 110 then 100 gigs but it fails each time at resizing the current partition.

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?

I made a partition on my macbook pro (128gb SSD) and I made it a bit too small. I went into disk utility and when I click on the main HD it will not let me resize it by dragging the corner up. I am down to 3gb of Bootcamp space. I could not afford the 256gb SSD so it is what it is.

Running Win 7 Ultimate 64-Bit and OS X 10.6.5. Winclone version is 2.2. I attempted to enlarge my Bootcamp Windows partition (deleted, resized to full, and then resized again with Bootcamp Assistant). I've made several attempts without any success. I have two Winclone images (11/2010 & 1/2011). The latest image doesn't even get started good before I get an error about 2 bad sectors and the one from last year runs all the way through and gives an error at the end. I ran disk repair on the complete partition before rezizing back to bootcamp and it still didn't work. I managed to get a win 7 repair disk to run one time and ran chkdsk on the bootcamp partition that returned no errors. I thought I might be able to install Win 7 fresh and then do a restore from a Windows system image that I have, but I can't get my Windows 7 disk to work when using the Bootcamp Assistant (I get a boot screen with two options (1. & 2. with nothing else visible) at the install point of the process and can't go past there).

I have a 500GB external hard drive which is partitioned for Time Machine and a separate data area. I have bought another drive for extra storage space and would like to re-partition my 500GB drive so that Time Machine has the whole drive. So basically I need to delete the data partition and resize the Time Machine partition to use the whole drive. I did look at iPartition but apparently it doesn't work with Leopard.

With Leopard's new Disk Utility, can a Bootcamp partition be non-destructively resize? Or is it still necessary to clone the Windows install, redo Bootcamp, and restore Windows?
I found my Bootcamp partition is too small and will need to be resized eventually (or, rather, games are much much larger than I realized ). But I really don't want to reinstall Windows to accomplish this.

I have a 10 GB encrypted disk image on my macbook (type OS Extended (journaled)). I've pretty much filled up the space so I want to resize. I go into disk utility with the disk unmounted and 'Resized' it to 20GB. Then I mount it and go into the Partition tab. I drag the corner all the way down to fill up the space and hit Apply. It goes through the motions without error but it does not actually extend the partition to the resize. On the right next it then says something to the effect that the disk is read only and cannot resize the partition. The write status is read/write until I click apple....then it switches to 'Unmounted, read-only'.

I have XP running beautifully on a 150 GB Raptor (via bootcamp). I'm thinking of adding Vista, but I'd like to avoid formatting the drive and creating two partitions for XP and Vista.
Can I slice off some of the 150 GB for Vista leaving XP intact?

So, I am in the process of attempting to partition my disc so that I can boot windows XP.
Know that I am in no way even a capable mac user, so I might be a bit slow... sorry.
During the partitioning process, using boot camp, I get a message saying that I need to reformat my disc so that it is a single Mac OS Extended (Journaled) disc. So, I go to my Disc Utility, and it says it already is a Mac OS extended bla bla bal. So, my question is
Why will it not let me partition, and do I really need to reformat my everthing eventhough it already is in the format it wants to be in?

I'm unable to find out how I can create a primary partition on a USB stick using OS X (I could just go to my Windows or Linux machine and do it there, but it just annoys the hell out of me that I haven't been able to figure out how to do it on my Mac so far).
I want to make one partition of the USB stick bootable (to keep a Windows 7 installation CD image on it) and use the rest of the USB stick for a data partition, but while the Disk utility allows me to generate two paritions, I can't find a setting that allows me to specify that one of them is primary.
