Changing partition size without reformatting drive?

I heard a rumor that in Leopard you can change the size, name, or other details of a partitioned HDD without having to erase and reformat it.
Is this correct? If so, that would be a huge advantage for me, as I often don't predict how much drive space I'll need to use.

Tell me if I'm wrong, though, but it seems that DU can only shrink. So, if you have 2 partitions, after you shrink one, you can't increase the size of the other. I hope I am wrong here. Please let me know if your experience is different. I think we'd all like to know how it goes, regardless.
That said, VolumeWorks can do as you require. DO NOT do this without a backup of everything.

  • Changing Partition Size without Deleting (bootcamp)/ Vista Question

    Hi, I'm currently running windows xp and OSX together with bootcamp on my black macbook (2 gigs of ram).
    I want to install Vista but I don't have anymore space on the Windows XP partition (just 4.42 gigs left). Can I partition my drives again where I get more room for my XP drive without deleting or messing up any of the information?
    Also , can I even use vista ultimate upgrade on my macbook?

    Hi,
    I believe boot camp is not supporting upgrade version of windows OS.
    Run you boot camp assistant to changed the partition size, but I think it will delete all of the XP that already installed there, but you don't need that again if you want to install Vista in that partition right?
    do visit boot camp forum for more answer from their experienced user.
    Good Luck

  • Can I change partition size of external HD without losing Data

    I have an external HD that I use one partition for backup and use another partition for Time Machine. I need to change the sizes, need more on my backup. Can I change partition size of external HD without losing Data? I just changed from a Powermac G4 using Leopard to a Macbook Pro with Lion, so I am also thinkin in getting everything set up, format the Time Machine with the old stuff and make a new Time Machine.

    The Disk Utility can't change the starting point of a partition without erasing it and the data on it.

  • Is there a way to change clip size without losing image quality? Specifically from 568 x 320 to 1920 x 1080?

    Is there a way to change clip size without losing image quality? Specifically, from 568 x 320 to 1920 x 1080?

    No, especially not video files. That's way too much scaling.

  • Changing partition size

    Is there a way, actually a reliable way, to change the sizes of the partitions on my internal hard drive without reformatting? I am using OS X 10.5.6 with an Intel Core 2 Duo iMac.

    OK. I tried that. My problem is that I have three partitons. Partition One has OS X and Apple applications. Partition Two has my Users folder. Partition Three has non Apple applications. I made the middle one smaller thinking that I could increase the size of the third. Well apparently you can't do that (the third partiton wasn't able to be made larger), so I put the middle one back to the way it was.
    The bottom line is that I bought a new external HD and I moved my User folder to that drive, leaving me with an 80 GB windfall on my internal drive. Now I'm thinking of just leaving things the way they are, but moving my applications to the now larger partition (where my Users folder was). Would that be a problem as far as running the applications (these are all non Apple apps)? Moving all these apps is a lot easier that having to reinstall them.

  • Not able to change the size of the Drive

    Hello ,
    I have a template with 50 GB C drive and I want to a create a VM having 100 GB C drive using this template  . But I am not able to change C drive size from the edit settings . After changing the size from the edit settings to 100 Gb , I found that in newly created VM the size of the C drive was 50 Gb.
    If it is possible to change the C drive size to 100 Gb without making any changes in template ?
    Can anyone suggest me how to do this ?

    This question should be posted in a forum area related to a product - are you using vSphere, and if so which version?

  • Change partition sizes after windows has been installed

    After I have installed windows onto my mac and have created the partitions, can and how do I change the size (in terms of memory) of the partitions without reinstalling all information?

    Hi and welcome to Discussions,
    you can use WinClone for this http://www.twocanoes.com/winclone/ and in here http://www.twocanoes.com/forums/viewtopic.php?t=515 you find a how-to.
    (Topic: My current Windows partition is the wrong size, and I want to make it larger. How do I do this?)
    Other people have used CampTune http://www.paragon-software.com/home/camptune/ successfully.
    Prior to doing this you should make/have a backup of your OSX and Windows files for safety.

  • Maximum Partition Size for External Drive using DU

    Hello,
    I just purchased a 750g Maxtor USB drive for use with Time Machine. When I went into DU to partition and format the drive I was surprised to find that every time I went to create a single partition using all available space, the operation would error out. I was however able to create two partitions with the largest one sized around 650g or so. I was using the Mac file system.
    This just seems odd to me. Does OS X have a maximum allowable partition size that prevents me from creating one large partition?
    Thanks,
    Robert

    Hi Robert
    You should be able to delete the partition, try again using the instruction in the following article:

  • Change slide size without resizing objects?

    Is it possible to change the slide size without causing Keynote '09 to resize all the objects on each slide?

    As far as I can tell it's not possible. You have to make a new presentation with the size you want and copy paste everything from the previous presentation into it.

  • Changing partition size and migrating to Leopard

    My iMac currently runs OS 10.9 and has boot camp installed, but I chose a Windows partition size that was too small (only a few GB, enough to install Windows XP). I am now want to increase the size of the Windows partition and to install Leopard. What is the best order for me to change the partition size and install the new system? If the disk needs to be wiped clean to do this, what is the best way to back up the existing data and then to reinstall it. Would I use migration assistant?

    If your beta Boot Camp Assistant hasn't expired, you COULD do this before you upgrade to Leopard. If it has, you can play games with the date, or you can do this after you're on Leopard.
    Either way, if your partition is FAT32 you can back it up using Disk Utility, according to other posts (see especially backup/clone discussions in the beta discussion forum); if it's NTFS, Winclone is probably the way to go. If it's a real small partition, though, you might just start over, or back up only what's "yours".
    On either the beta or Leopard, you'd want to back up or clone the current Boot Camp partition, remove it using BCA, create the new larger partition using BCA, and then restore the contents.
    None of this requires wiping the MAC OS disk, it DOES essentially wipe out the WINDOWS disk. I don't think Migration Assistant helps here, but certainly haven't tried that.

  • Cannot change partition size on firewire external drive

    My external firewire drive has three partitions, one of which is used for Time Machine and is out of space; the third one is empty. When I use Disk Utility to try to increase the size of the second partition without erasing its contents, I get the message: "Partition failed with the error: filesystem resize support required, such as HFS+ with journaling enabled".
    Can someone please advise me on how to proceed.

    How have you formatted your drive?
    My drive is formatted as Mac OS X Extended (Journaled) and I have not trouble resizing my partitions with disk utility. I remember reading somewhere that certain formats do not support on-the-fly resizing. If you are using one of those formats (which I would guess based on your error message), you may need to re-format your drive. This would mean erasing everything (so make sure you back up your drive first). If you do have it formatted in the same way as me, I am not sure why you are getting the error.

  • Format and partition HD without external drive - how to...

    Just got a new previous gen imac and before I start saving stuff, I want to partition the drive. I'm thinking this can be done with the install disc. I'm wanting to make a partition for a Superduper Sandbox, and a scratch disc for photoshop. Is there specific directions for doing this without an external drive anywhere?
    I'm not sure how important it is to have a scratch disc as I'll have 3gb ram, and I'll leave a lot of free space....any thoughts on this?

    You can do it from the install disk by booting from it then instead of doing an install select a language and then, go to the utility menu and select "Disk Utility". You can then create the partitions you want, name then, and decide the size of them. After that you will have to install a new OS. Remember that doing all of this will erase the drive, so if you have any data on it you want to keep you need to get it of first.
    Mac Help can guide you through this process. You could also open up the Disk Utility application which is in your utilites folder and use those application specific help files. I am making this sound complicated but really, it is not.

  • Changing partition sizes

    I have two partitions on my 320 GB hard drive, and want to make one smaller and one bigger. When I try to resize them all I can do is make them smaller. When I make one smaller, it displays a bluish section between the partitions, which I assume is "nothing," but then I can't make the other partition any bigger. Is there a way I can do this? I don't want to erase the whole thing and redo the partitions.

    I have tried, and it doesn't let the 2nd (or lower) partition inherit the space that was used previously by the partition above.
    Seems like a natural enough idea, but of course the safest is to backup and restore.
    Also, if you use BootCamp, don't, and resizing or creating partitions in OS X or Windows can have side-effects, like Windows OS partition no longer showing.
    Partitions - or their use - always change over time, which is one of their downsides.
    Apple Disk Utility Restore or other programs make the backup / reformat / restore easy and painless. I'd recommend checking into SuperDuper.

  • Create Boot camp partition on multiple partitions disk without reformatting

    Hi everybody,
    I am trying to install Windows 7 on a multiple partitions 1TB disk.
    Currently I have 2 partitons:
    300GB - OS X Lion
    700GB - Data
    I have read some tips and advices on how to install windows on multiple partitons disks - most of them are invasive (backing up to a removable drive and then reformatting). However, I haven’t found conclusive answer (hence my posting here):
    I’m wondering does anybody know in any way - is it possible to do this more painlelssly - to divide second partition (or maybe first) and use that one as a bootcamp target?
    Or am I stuck with reformatting to a single partition and then installing from scratch?
    Thank you.

    No. To use Boot Camp Assistant your drive must start with a single volume encompassing the entire drive - one partition. BCA will then create a second partition for Windows and modify the bootloader so you can select which volume to use for startup - OS X or Windows. BCA can also remove the Windows volume and restore the drive to its original state - single OS X partition.
    If you have more than one partition already then BCA cannot modify it. If you have a drive configured with BCA and subsequently add a third partition then BCA is no longer able to manage the drive, and you may no longer be able to boot Windows because of changes made to the bootloader.
    So, yes, you are stuck with "reformatting to a single partition and then installing from scratch."
    Your alternative is to create however many partitions you want. Install Windows on one of them. Download rEFIt to replace the standard bootloader so you can select between Windows and OS X (or any other OSes you install.)

  • Changing partition size of boot disk

    Hi, i have an imac 5.1, i use an external drive to boot from which has 2 partitions, the one i boot from and the other part has files and stuff. i want to make the boot disk space bigger and the other smaller, how would i do this? thanks.

    The idea of seperating the data from the system is a poor reason to partition the system drive.
    Backup the data.
    Reformat to a single partition and restore the data.
    This will allow OS X to handle disk space for you instead of you having to do it.
