OS X :: Resizing A Partition Without Losing Data?
Jul 5, 2009
I know there are already a ton of threads like this one out there, I was just getting a lot of conflicting data from them, and didn't really want to screw this up... Well here's the problem.My HDD is currently divided into two partitions, I am trying to shrink the 2nd partition, and expand the 1st without losing the data on my 2nd partition. Is this Possible?
I've tried VolumeWorks 1.5 from a bootable DVD but for some reason when I open it and select my hard drive, the left column where a list of my partitions should be is blank, and all the buttons on the bottom are blanked out except "close" and "rebuild".
I was going to try booting from CD and running disk utility to accomplish this, but most of the stuff I've read says that shrinking a partition with DU will erase the data. ?

I would never opened a topic like this if I had not a similar experience with expanding 'dmg' in the past!
A truly bad experience! It is supposed that using 'disk utility' I can resize-expand-make bigger any dmg file. Every time I tried it, it was a totally fail process.The 'disk image' dmg did not resized at all.
I do not know why, it just happened to me many times.
Does anyone had similar experience? Any solution to this? So if I have a dmg that need to be bigger, I create a new one from scratch and I copy paste files from the old dmg.I need to do the same with hard disk partitions, using disk utility once again. I need to resize my hard disk partitions.Does this process works well as it should be, or it is a bad-implemented feature?

How do I partition my external hard drive without losing the data already on it? I've been using it with Time Machine on my old computer, but want to use it as a regular drag-and-drop type back up on my new computer. Is there any way to basically split the hard drive so I can still access the Time Machine backups on my old computer, but also be able to use it with my new mac?

MacBook Pro, Mac OS X (10.6.8)

I am dual booting XP Pro and OS X on my NC10. I have XP Pro installed on the main partition with a FAT32 partition for files that can be read by both OSes (see attached image for two views of the partitions). I then installed OS X on an extended partition. Unfortunately, I had another 5GB partition also on that extended partition. I now want to delete the spare 5GB partition and non-destructively reallocate the space for the OS X partition - I want to expand it to be one big partition with my bootable OS X install still on it. Unfortunately, I can't find any way to do this in Partition Magic. Is it possible with GParted/BootItNG/iPartition or any similar software? If so, which and how? The NC10 has no CD drive so solutions that work from OS X or XP or a bootable USB stick would be preferred.

i have a macbook pro on which i've installed windows xp, i made the mac and windows partition equal which was a mistake thinking will use them as much as one another, but it turned out to be that I'm barely or never using my windows on my mac, and I'm running out of space very quickly. I need to know how to make the windows partition smaller and the mac partition larger. I need an answer quickly because i've only got 4 Gb's left on my mac partition and 40 Gb's left on the windows one.

I just deleted Windows Partition 30g on my Macbook.
If I resize the MAC one to fill that 30gig back up will I need to backup? I know I know you should always back up but does it intentionally remove data? Or is it straight forward?
Just asking before I do this in Utility.

I have a 700 GB external HD with a 349 GB MacOSX Extended (Journaled) partition, and a 349 GB FAT32 Partition.
I need to shrink the FAT32 partition to make room for another smallish HFS+ partition so that I can back up my virtual machine (around 30 GB). My question is whether resizing the FAT32 partition in Disk Utility will harm the data in either of my existing partitions. I understand Leopard to have an on-the-fly partitioning ability, but I wasn't sure whether this applied only to certain file systems.
I am running OSX 10.5.8.

I have a 320 GB Western Digital drive connected to my Macbook Pro 5,1. I have 2 partitions on the WD drive, my Time Machine partition and a FAT32 partition of about 32GB. My Time machine partition is getting pretty close to being full, and although I know that Time Machine will just delete older backups if its partition is full, I don't really have a need for the FAT32 partition anymore.
In Disk Utility, by selecting the external drive and choosing the 'Partition' tab, I am able to erase the FAT32 partition and leave a free space on the drive, but I can't find a way to expand the Time Machine partition to use this space. The TM partition has a slider, but it can only decrease the size of the partition, not expand it.
The free area on the disk shows up in the partition map as a greyed-out area above the TM partition. Any ideas? Is it possible to extend the TM partition to the rest of the disk?

I am trying to resize the bootcamp partition on my iMac. I opted for the 32gb option when I first ran bootcamp but I wanted to add more. I read online I could do this my shrinking the Mac HDD and then creating a new partition FAT32. Then open up windows and open up disk management. Then right click my bootcamp hdd and click "extend volume." however, that option is greyed out. Am I missing something or is there some other technique?

I'm trying to use my 500 GB external HD as solely a storage drive now whereas it used to be storage and backup, with separate partitions for each. I have deleted the backup partition (the first partition) successfully with Disk Utility, but how can I resize the remaining partition into the free space before it on the disk? I can't drag it or enter the desired size in the text box, it doesn't seem to want to get any larger. Is there any way to do this without purchasing ipartition? I have an old version from Tiger, but I'm not sure if that will work safely on leopard, and I do not want to lose my rather larger collection of ripped dvds on this external drive. Here's a screen shot of what i now see in disk utility.

I have an Apple RAID card installed with the following configuration:4 x 2TB HD'sRAID 0+1Yielding a 4TB RAID setPartitioned into:Partition 1: 40GB StartupPartition 2: 40GB Backup StartupPartition 3: The remaining available disk space into a Data drive
The idea was I would have a reserve volume I could load another system onto and it would come in handy.
The problem is that I didn't know that the startup drive was going to have to have an accounting application running on it that needed to have its data on the same volume. This data is growing rapidly and I am in need of expanding the volume. I have a backup of the whole setup.
From what I can gather from my searches, I should be able to resize these partitions but I wanted to know if anyone out there had a similar setup and had tried this. Right now there is no data on Partition 2 so my thought was to delete this partition from the RAID set and then expand Partition 1, doubling the size of my startup. This would get rid of my backup startup but I could achieve that with an external drive.
My hesitation is because I can't find any reference to doing this with a RAID 0+1 scheme (I would have preferred 1+0 but the RAID card didn't offer it...).

Well my Mac has been running slower and slower and I believe it's just about time for a clean install of OS X. Now this will be the first time I have to do this on a Mac so I don't want to jump in without some insight on some things.
First, is there any way I can keep my installed programs, and what (besides the Applications folder) should I back up for this? I'm thinking iWork, MainStage, and a couple of other large programs that I honestly don't want to lose configurations in or redownload (MainStage took me 3 days). I heard there's a way to restore just the operating system without affecting any user data. By the way I'm running the latest iteration of Lion and have a full (tested working) Time Machine backup running as well.

I'm just trying to make 2 partitions, one on my iMac, and one on my external usb drive. I don't want to lose any information though.I've read an article, there is a way to do it in diskutility but its all command line stuff, I don't feel comfortable with doing that in case I mess something up.
another method I guess is iPartition 3 for leopard. Don't know if this is any good though.Is there any free way to just create these partitions maybe with a GUI ?

I've installed and uninstalled windows couple of times through the Bootcamp. when installing the Windows 7, it asks to format the partition so that the Windows can be installed. My questions comes here, I also restored the partition couple of times for no reason and whenever I restored it, I noticed that the space used by Windows never gets added back up to Mac Partition. So does that mean the space used by Windows will be just floating around? To simplify my question: After restoring the Windows partition, the space used by windows, will it be added back up to the Mac partition(to 1 partition)?

Is there anybody that has gone from Tiger to Snow Leopard and did this as an upgrade? Did all your music and pictures remain on your HD? Is it even possible to do it this way?
When I put my snow leopard disc in my computer, it has 1 option which says: Install Mac OSX and if I press that it says, press continue to restart your computer and installation will begin (or something like that). It's not clear to me if it's gonna erase my harddrive or not.

Basically, I created a BC partition for my W7, however, I only gave it 32gigs of space (I only wanted to use it for gaming).However, now I want to install Autodesk 3D Studio Max 2010 on W7, however I don't have enough space on my BC partition to do that...I've researched enough to know that I will need to use one of the following programs:I've read up on all the programs and done some research on them.
Ive noticed most people are having problems with all of these programs when trying to backup a W7 image whilst on Snow Leapord (Mac OS x 10.6, which I am running)I know that is the function of the 3 applications above... But to my knowledge... In theory - I should be able to just backup my W7 using a reliable backup program (Can someone recommend any?) and then delete the existing BootCamp partition, create a new one of 100gig and then just load up the backed up image for Windows 7...

im on a goal to resize my bootcamp partition... im running 10.6.4 with Win7 in Bootcamp... i made a mistake of only making a 80GB partition for windows 7.... now i want to make it bigger, i have read up on a number of methods but most are outdated and users report issues with windows 7 and SL so i'm a lil stuck... this is my idea
I have 120GB unused HDD space atm so could i.. back up my 80GB partition to a DMG with disk utility then delete the old partition making the whole 200GB unallocated space... then use the bootcamp utility to re occupy the space then use disk utilities restore option to restore the image of the 80GB to the new 200GB partition... would this work? if not has anyone got any other methods to use with 10.6.4 SL and Win7?

migrate my music to another computer, but I'm afraid of losing what I have checked and unchecked in "music" library.So let me explain a little more, not a created playlist or smart playlist. If you were to go through every single song you have and uncheck what you don't listen to this is the "master list" I'm referring to.
