Resizing a partition without unmounting

Is there a way to resize a partition that's mounted read-only, as opposed to unmounted? Parted doesn't seem up to the task. :oops:

Not looking good, Google  seems to think no. Maybe you could order a Knoppix CD or see if you can suck up to someone here and try and get them to post an Archie CD to you. Even if it doesn't come with the tool you want, just install it.

  • Resize boot partition without loss of OS on C:\ drive and data loss on D:\ drive

    I have an SBS 2011E server with a RAID 1 Mirror.
    I need to resize the C:\ drive which has the OS on it.
    The D:\ drive has lots of space on it but it also has a SQL Database that is ArchiOffice and some other minor software.
    Can I shrink D: without loss of data and can I extend C: without loss of OS using Disk Management?
    If I need third party software, which do I need?

    Hi Susie2229,
    Based on your description, I test in my Lab environment. However, it seems that can’t achieve your target via
    Disk Management.
    I Shrink Volume on E drive via Disk Management. Then an unallocated partition occurred. It’s in the right of
    E drive (if the unallocated partition is next to C drive, you may be able to extend volume). However, when I right click the C drive, the Extend Volume option is grey out. I can’t extend the C drive by using that unallocated partition. If my testing process
    didn’t follow your original thoughts. Please feel free to let me know.
    There is a similar thread that you can refer to. It may help you.

  • Is it possible to resize the partitions without losing data?

    I have following issue:
    I have dual-boot Arch with Windows XP. I created 4 partitions: 40GB XP's system disk (ntfs), 80GB ntfs data disk, 1GB swap and 25GB Linux partition.
    But I am running XP so rarely, that it is frustrating, that I have most of my data on ntfs partition... I'd like to wipe out that 80GB ntfs, resize the system ntfs partition up to for example 60GB, and add the remaining 60GB to my linux ext3 partition (because I'm running out of free space recently...).
    Has anyone done something like this, and how safe it is (if possible at all)
    Yes, I have read this: http://wiki.archlinux.org/index.php/Res … _partition, and a few more.
    I just don't have time to reinstall both systems (especially I would not like to install Windows, because I'd rather install Vista from my recovery disk, than hack the XP to work again...), and if some issues are likely to appear, then I'll give it up for now .

    It's trivial using gparted, but as with any similar operation, you run the risk of losing data - so you'd better backup.

  • How to resize my bootcamp partition without deleting  itit

    How can i resize my bootcamp partition to make it larger without deleting it or having to reload windows?

    Yesterday expanded my bootcamp partition from 50 up to 100 Gb using Mini Tool Partition Wizard Home Edition, a Freeware Windows Program after seeing this video: http://www.youtube.com/watch?v=WeKeawqxUa0
    Note that I have OSX Mavericks, Steps are:
    1) backup all your files (optional but strongly reccomended).
    2) Using OSX Disk Utility resize MacintoshHD partition leaving unallocated space as much as you need to add to bootcamp partition.
    3) Set Bootcamp as Boot Disk and restart the mac.
    4) in Bootcamp with Windows running launch Mini Tool Partition and select the bootcamp partition.
    5) Choose "expand" option in order to expand the partition using all the unallocated space.
    6) The program prompt to you to restart the mac for apply the task, cause is not possible while the partition is mounted and windows running.
    7) Restart the mac and then automatically Mini Tool Partition will do the job in a "graphic msdos like" form.
    I was lucky and worked for me, I have a Late 2009 Mac Mini with MAVERICKS and a samsung 250Gb SSD Evo.
    Hope this can help the community but decline any responsibility,  do it at your own risk, you can use programs like winclone or camptune if you feel more comfortable with a pay app.

  • Can I resize my bootcamp partition without reinstalling Windows?

    Hi
    I have recently installed an OEM version of the Windows 7 and I have allocated 50% space in the bootcamp?  I want to resize the partition now, to allocate lesser space for Windows.  How do I do it without reinstalling my Windows?  I mean I can't re-install my Windows as the OEM version allows only 1 installation. 

    CampTune from Paragon http://www.paragon-software.com/home/camptune/ but it seems not yet Lion-enabled.
    (The System requirements only mention up to Snow Leopard).
    But since you are doing a reinstall of WIndows onto the same computer as the first time, you are entitled to use your OEM version for it.

  • Resize partitions without erasing existing data

    I have one drive (internal), dual partition (OS X 10.5.2 and Vista) and I want to split the volume OS X 10.5.2 in two. I try this using Disk Utility, but one warning was showed: ..changing the partition map may make this disk unbootable using windows"
    Is it warning true? What do I expect to happen in case of resizing?
    If someone had have any related experience about that, I will appreciate Your advice.

    You can resize partitions without losing data but you won't be able to boot into Windows after that. That was a bad experience I had. My first bad experience was to repartition a dual-partition (Tiger+Windows) drive, ignoring the warning. Guess what? Lost everything and had to reinstall both OS.
    Mac OS X Extended (journalled) drives can be repartitioned without losing data using the "diskutil" command in the Terminal window. Type "diskutil" and you get a list of available commands.

  • How to back up Boot Camp and how to resize FAT partitions

    I suppose someone has already addressed this topic herein, but in case someone needs help I am leaving with you what I learned.
    I started with a partition sized to 18 gigs and installed Windows XP on it. Soon the drive became full after I installed software and various disc images so I can play games. I wanted to resize the partition to 28 gigs without losing my data, leaving 46 gigs on my Mac partition.
    I was not sure what would work so I chose several methods of possible restoration. The easiest was to boot to the Mac and use Disk Utility to make a Disk Image of Boot Camp. The next precaution I took was to back up my settings with the Windows Files and Settings Wizard. Lastly, I booted to Mac and turned on viewing of hidden files. Then I copied all the files off the Windows XP partition onto an external drive. I also tried Acronis True Image while in Windows but it was not compatible.
    I also discovered a free program called Winclone (http://www.tuaw.com) that makes an image of the Windows partition and restores it for you, much like Disk Utility works.
    In OSX, I ran Boot Camp Assistant again to rejoin the partitions. Then I ran it again to partition the new drive to 28 gigs.
    The first thing I tried to do was to use Winclone to restore the Winclone image. That failed with errors. Then I tried to use Disk Utility to restore the drive and Disk Utility would not allow me to restore the disk image onto the drive. I am not sure why Apple is so unsupportive of implementing their Disk Imaging technology within the context of their own self-created Boot Camp technology.
    Anyway, the last thing I could try was to copy the files back onto the new partition or to give up and reinstall Windows and use Files and Settings Transfer Wizard to restore my Windows settings.
    After partitioning the drive with Boot Camp Assistant, I copied the files over and rebooted. Windows said there was an unsupported drive. Then I realized that I missed a step in the installation instructions provided by Apple for Boot Camp. I forgot to format the drive again using the Windows XP install CD, that the Apple says is necessary.
    So I booted up the Windows cd and erased the Boot Camp partition and made it a FAT drive so that I would be able to copy my files over to it from OSX, which I would not have been able to do had the drive been formatted as NTFS.
    As XP started to install its software, and it started to copy files from the cd, I pressed the power button to shut down the Mac. (Do this at your own risk. I am warning you that this could damage your computer, so do NOT try this if you feel uneasy about it.)
    I booted into OSX. Then I trashed the few files that Windows had started to install on the Boot Camp drive. Then I copied all my backup files back onto the partition.
    Here is a widget that will allow you to view hidden files in OSX: http://www.apple.com/downloads/dashboard/developer/hiddenfiles.html
    I rebooted the Mac and held down the Option key while restarting. When the Mac and Windows drives appeared at the startup screen, I selected Windows, which booted up successfully. It then recognized the partitioned drive as new hardware and required me to restart, which I did.
    I wanted to convert my drive from a FAT drive to a NTFS-formatted drive.
    This is how I did that:
    http://technet.microsoft.com/en-us/library/bb456984(TechNet.10).aspx
    After converting Boot Camp to NTFS file system I noticed an immediate speed increase in Windows XP. I
    In conclusion, Disk Utility is a good method of backing up your partition, as it allows you to use a password to make a disk image of your drive. It also allows you to copy the files off the disk image onto the Windows partition. But it would be a lot simpler if Apple allowed them to use Disk Utility to restore the whole image back onto Boot Camp.
    Other methodologies I did not get to explore because I am happy with my results:

    After copying your files back to the Boot Camp partition you may get this error message when you boot up Windows XP.

  • Cannot resize system partition due to recovery partition

    Hello.

    Error: -5341: MediaKit reports partition (map) too small
    I want to resize the partition to use the remaining new space i have, of course, and create a bootcamp part.
    I am wondering if i can kill the recovery partition without destroying my lion. As i have the recovery transfered successfully to usb stick using the apple utility, i am able to use it anytime.
    But... just wondering if that would crash my OS or not.
    Or, if anyone sees a way to move the recovery partition to end of the HD so that i can enlarge successfully...

    Thanks to you both, luckily there's only 600GB on that drive at the moment.
    I was wondering, though, why won't it let me make it bigger?
    I already had a 1TB partition in the space below it. The screenshot shows me having already deleted it - but still no option to resize the other (larger) 2TB one.
    If there is a reason why I can't resize now, then I can take that advice and try and make sure it doesn't happen when I reformat it again.
    I would understand if the partition were MBR, but it's not, it's a GUID Partition Table (bottom right), so I'm confused - what is it's problem? ;-)

  • Can't resize disk partitions after Yosemite install.

    My disk has two partitions. I run Mavericks on the first, and recently installed Yosemite on the second. The OS works fine, but I no way to resize the partitions. I've tried booting into both Yosemite and Mavericks but the partition layout in disk utility appears locked with fixed partition sizes.
    It now appears that I have two options.
    Use the undocumented "resizeVolume" command in diskutil to resize the core storage volume in my Yosemite partition, or
    Use the "revert" command in diskutil to revert from core storage to the default partition type and try my luck.
    Is anyone else facing this issue of not being able to resize your disk partitions after the Yosemite install, and if so, how did you resolve this?
    Thanks in advance.

    None of these worked. I had to resolve this the hard way.
    Make a complete TM backup of the new Yosemite installation.
    Use a bootable install DVD or USB drive, re-partition the disk and do a complete reinstall.
    Recover the applications and data from the TM backup.
    It took me about an hour and a half once I decided on this approach, not counting the hours wasted trying to get it working.
    To give them credit, the TM backup and restore worked flawlessly and all my apps and data were back without a hitch.
    However, reading the other posts in the forum and elsewhere it does appear that Apple has not done a good job with the disk utility in supporting core storage volumes, which is fairly ridiculous since Yosemite defaults to that without giving you a choice.

  • Boot choice disappear after resizing main partition Mac

    I wanted to resize the partition mac for more space later on Windows partition. But when the operation ended and I rebooted, I had no choice boot between windows and mac.
    Now it boot, without asking my opinion, directly on the Mac partition.
    How to fix this problem, so I can restart my Windows partition.
    Thank you in advance for any help or advice.

    Hi and welcome to Discussions,
    use Diks Utility in OSx to check if you maybe inadvertently made a partition between your OSx partition and the Windows partition while shrinking your OSX partition.
    If so, then the 'partition numbering' has been changed and the Windows partition is not found.
    For XP have a look at this thread http://discussions.apple.com/message.jspa?messageID=11783594#11783594 for a solution.
    For Vista or Windows 7 EasyBCD http://neosmart.net/dl.php?id=1 would be my tool of choice.
    Hope it helps

  • 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.

  • Is there a way to go from a case-sensative partition to a case-insensitve partition without completely wiping the drive?

    I've begun to notice that not all apps support case-sensitive partitions. I know that repartitioning or reformatting will just wipe everything and conversions don't usually work because of naming overlaps. But I had an idea. What if I created a second, case-insensitive partition? You see I have 100GB free. So if I create a 100GB partition, move 100GBs over, resize the partition into the new free space and repeat. Soon I would have all my files moved onto a new case-insensitive partition, and I could delete the old one and completely take it's place.
    The only problem I see is the OS. I know the files won't mind the move, but the OS I'm sure is a problem. Maybe I could make the 2nd partition, install mac on it, and then move my other files over bit by bit, resizing the partition as I go. Is there a way to import my prefs and settings from an adjoining partition?
    I just want to know what the problems with my idea might be. Is it risky? Am I a mad man?

    Yes. Just select the volume in Disk Utility and select erase. Case-sensitivy is selectable. However, I've never understood the PC case-sensitivity usage and would never recommend it. Finally, AFAIK, the OS handles either.
