Disk Utility - Unable to Shrink Disk Error

hey guys,
I have been trying to shrink my system partition but i keep getting an error.
I had Vista installed on a boot camp partition, but i needed to reinstall it and i decided to start from scratch. I erased the vista partition and tried to recreate it. I ran boot camp assistant but that failed at creating a new partition.
I ran disk utility to first try and shrink the system drive, then increase the size to full before i rerun the boot camp partition. however, i cannot shrink.
this is the error i get.
http://dl.getdropbox.com/u/734117/Screen%20shot%202009-10-25%20at%208.48.54%20AM .png
I had only about 35 gigs free and i tried to create a 20 gig partition. after that error, i erased some data and now have just under 100 gigs free. but the drive still cannot shrink
I was hoping to find a way to shrink the drive, or defragment without having to erase the entire disk and reinstall. i do not have the backup capabilities to move all my data at this point.
Thanks for your help

How do i create a clone?
first, you need an external drive. then use CCCloner http://www.bombich.com/index.html
or Superduper http://www.shirt-pocket.com/SuperDuper/SuperDuperDescription.html
to clone the OS X partition to the external. make sure that the external is formatted with GUID partition scheme before cloning. if needed reformat it first with disk utility.

  • Disk Utility has been Shrinking disk for several hours....

    I have an external HD (FW800/GUID) that has 2 partitions in it that I'm trying to reduce the size of one of the partitions to make room for a third without deleting anything on the drive. Disk Utility has been 'shrinking disk' for several hours and I'm debating if it's hanging. I see no activity on the drive, so I'm not sure what's going on.
    How long should this typically take to finish?
    the partition in question has about 1.3T of data on it and I'm trying to free up about 300G that's unused.
    Should I be concerned? How long should I let this go before bailing the app?

    What's the chance that the data will be corrupt if I force quit disk utility?
    In the middle of repartitioning that has apparently hung? I would guess it would range somewhere from high to certain. You should immediately use Disk Utility to repair both partitions after force-quitting.
    I didn't make a backup
    I hope you're lucky, but I have the feeling you're about to learn your lesson about not having backups in a very severe way. If the drive cannot be repaired at this point, you may need a file recovery utility like [Data Rescue|http://www.prosofteng.com> or [File Salvage|http://subrosasoft.com/OSXSoftware/index.php?mainpage=product_info&productsid=1].
    In the future, you absolutely must have a minimum of two backups (three copies) of any data you can't afford to lose.

  • Disk utility unable to repair disk. What next?

    Disk utility unable to repair disk. What next?

    I encountered the same problem. After verify disk, I got the message to repair the disk. But it was unable to complete the repair. Rather than purchase Disk Warrior, I tried something else.
    What I did was reinstall the OSX (this iMac is still on Leopard). I backed up everything, naturally, before doing the reinstall. I chose the "Archive and Install" option, along with "Preserve Users and Network Settings". This method moves  existing files to a folder named "Previous System" and imports existing user accounts, network settings, and home folders into the new OSX.
    After the successful reinstall, I ran Disk Utility. It checked AND repaired Permissions. It verified that the disk was fine and no longer needed repair.
    If this didn't work, my plan "B" was to reinstall the OSX again, this time with the "Erase and Install" option. Fortunately, I didn't have to go to plan "B".

  • Disk Utility - "Unable to create 'Desktop' -  error 49168" - What's this?

    I try to create a compressed disk image of my Desktop using Disk Utility and get the following error:

    Does anyone know what that means?

  • Disk Utility "Unable to create" Disk Image "error -39"

    I am trying to create a disk image using Disk Utility of my wife's user area for backup. Everytime I try, I get the same result. Disk Utility spends several hours creating the archive, then at the very end it generates an error message and terminates the process. The error message is always "unable to create "user" - error -39".
    The problem follows her data and not her computer. I backed up her user to an external drive and did the image creation on another computer. Same result.
    When I do the same on my computer, the process completes fine.
    What problem is Disk Utility having? Where can I find the meaning of Disk Utilitility's -39 error?
    PowerBook G4   Mac OS X (10.4.5)  

    I am still experimenting. To narrow the problem, I decided to create individual disk images of the folders in the User folder. The first one I tried was 7 GB and worked fine. Overnight, I tried one that is 13 GB. It failed with an out of room message on the startup disk! The startup disk has 17 GB free. Nothing should have been written to the startup disk!
    This time, I configured Disk Utility to read from the startup disk and write to an external disk. The destination disk had more than enough space. But, I ran out of space on the source. It appears that Disk Utility is writing all or a portion of the compressed file to either the startup or the source disk and running out of room.
    Previously, when I created the image of my user folder (instead of my wife's), the source was my user folder on the startup disk and the destinaion for the image was on an external disk. The difference I see is that my startup disk has enough free space for the entire compressed image file.
    In my first attempt that gave me the -39, both the source and the destination disks were external. So maybe Disk Utility is creating the image on the source and at the end copying it to the destination. This would explain the difference in the error messages.
    I'll try to confirm all of this in the next few days and report my findings.

  • Disk Utility unable to verify disk (Error -9972)

    Please help! I downloaded the Security Update 2007-004 and my comp crashed! When I turn my computer on I get a folder icon in the middle of the screen and it won't start.
    I tried using Disk 1 to get to my harddrive. I got to Disk Utility and tried to verify disk. But I got the following message.
    Invalid B-tree node size.
    Volume check failed.
    Error: The underlying task reported failure on exit. (-9972)
    So I can't verify and therefore can't repair my disk. I need my computer for my school assignment. Please please help.

    Welcome To Discussions jo*!
    Do you know what size the Hard Drive is, and how much space is available?
    Although that error is not exactly good news, it is not necessarily a death knell.
    DiskWarrior, does indeed, have a high success rate at rebuilding when Disk Utility reports "Underlying task reported failure" when repairing a volume (Error -9972).
    In the above link it states;
    *Back up as much of your important data and files as you can, then try using a third-party disk utility to repair the drive. Be sure that you use one that works with your version of Mac OS X."
    DiskWarrior, also linked above, is just such a third-party utility.
    But just in case it is unsuccessful, and you need to perform an Erase & Install, I suggest that if possible, you back up the system, or at least any data that you cannot afford to lose.
    If you have access to another Mac that is Firewire enabled, you might be able to backup, or retrieve data, using Firewire Target Disk Mode.
    Good Luck!

  • Disk Utility unable to repair disk

    My IMAC started to freeze up for a couple of minutes while running Word for Mac 2004 and Entourage. Microsoft tech support suggested running rebuild database for Entourage. Rebuild database did not execute citing I/O problem. Ran Disk Utility from Install Disk and it was unable to repair one volume after repeated attempts. Also tried ckfs but that found no errors. Some posts recommend Disk Warrior or other recovery software. Any suggestions before the trip to the Genius Bar?

    Disk Warrior repaired the disk on its first pass. Disk Utility confirmed the repair. No symptoms any more in Word for MAC and Entourage 2004. Still could not rebuild database. Will back up to be safe.

    Ladies,
    Gentlemen,
    I used Disk Utility to backup the internal hard drive of my iMac G5 iSight.

    Can any one help?

    If you want to create a backup of your system volume, then do not use disc images. They are not bootable. Here's a far better solution:
    How to Clone Using Restore Option of Disk Utility
    1. Open Disk Utility from the Utilities folder.
    2. Select the backup or destination volume from the left side list.
    3. Click on the Erase tab in the DU main window. Set the format type to Mac OS Extended (journaled, if available) and click on the Erase button. This step can be skipped if the destination has already been freshly erased.
    4. Click on the Restore tab in the DU main window.
    5. Select the backup or destination volume from the left side list and drag it to the Destination entry field.
    6. Select the startup or source volume from the left side list and drag it to the Source entry field.
    7. Double-check you got it right, then click on the Restore button.
    You can also do the same using other backup utilities that can create bootable backups:
    Backup Software Recommendations
    My personal recommendations are (order is not significant):
    1. Retrospect Desktop (Commercial - not yet universal binary)
    2. Synchronize! Pro X (Commercial)
    3. Synk (Backup, Standard, or Pro)
    4. Deja Vu (Shareware)
    5. Carbon Copy Cloner (Donationware)
    6. SuperDuper! (Commercial)
    7. Intego Personal Backup (Commercial)
    8. Data Backup (Commercial)

    Hi, I am trying to install some programs (on mac book pro mac osx 10.6.8) that are downloaded in "dmg" file format.  These are antivirus and security related programs.  Unfortunately when I try to open the downloaded file, this does not open and I get message it is not recognised.  I have also tried using Disk Utility but I get an error "unable to attach"l.  This just started recently.  I have downloaded the file several times but same problem recurs.  Thanks for your help
    PS: Other files directly downloaded from apple work fine.

    They screwed up the first Flashback removal tool very badly, locking several users out of their accounts permanently. It took a day or so for them to react and post a revised tool, but the damage had been done.
    They are one of several formerly PC only vendors who rushed to the Mac front back in the spring after the Flashback scare. I would advise giving all of those folks time to prove they really understand OS X before installing it on any of my Macs. There are several others who have proven themselves.
    Since you are running what I assume to be a fully up-to-date OS X 10.6.8 you are not vulnerable to any currently known malware capable of impacting OS X or other Mac software. That's no guarantee there won't be something new show up tomorrow, but the chances of any commercial anti-malware software catching it before Apple can react is pretty slim, IMHO.
    Now if you are concerned about Windows malware, that's a different story.

  • HT203176 i have a slow macbook, i ran live disk utilities and said I need to repair disk from a cd. did that, I got volume repaired from the external disk. when I reboot from hdd, then run disk utility, I get the same error message i did b4 repair

    i have a slow macbook, i ran live disk utilities (from hard drive), turned out I needed to repair disk from a installation disk. Did that, I got the volume (Hard drive) repaired from the installation disk disk. To this point, great!
    When I reboot from hdd, then run disk utility, I get the same error message i did b4 repair. I went thru two rounds of this.....
    Can anyone help? thanks

    Sorry guys, I don't see how to reply to you so I use reply to "me" basically.
    So the error I get is "volume header needs minor repair" and then you need to perform repair from the installation disk message.
    I did repair not verify from the disk twice. Every time ending in the "the volume had ha been successfully repaired". Then I reboot from the internal disk. Run disk utilities from it, do verify and get the same error message I got before repair. I hope this can shed some light fr you guys. Sorry I didn't include details in the original

    Thanks for any help!

    Lot's of problems there.  Hope DU can fix them.  You don't want to continue using that drive in the state it is in now.  Nothing wrong physically with the drive (I believe).  Just what's on it.
    You cannot repair the disk you are booted from, only verify it.  That's why repair was grayed out and that why its telling you to boot from another bootable disk.  If you don't have one then boot from your installer dvd which has a copy of DU on it.  Then try to repair your boot disk and hope it's successful.
    If it isn't successful, then you may have to try to use Disk Warrior (which has it's fans and detractors as to how "good" it is).
    Of course if you have a backup you could just erase the drive and recreate from your backup.  This is one of the reasons to always have backups.  Alternatively if you do have a backup, then you could boot from it as I mentioned above to run DU from there (hold down option key hear the boot beep to be able to select a bootable drive).

  • Macbook Pro not booting after update. ''Disk Utility can't repair disk''. Help needed!

    I have recently updated my macbook pro as I had some pending software updates. I left it to do the job over night and the next day I noticed it was not letting me sign in to my account session as usual.
    I restarted the computer and ever since then when I boot it, it just shows the apple grey screen with a bar that loads to about a 3rd and then it turns off again. I have contacted apple but they were unable to help me with this.
    So far I have tried to:
    1. Re-install OS X 10.8 - but it says the disk is locked or OS X cannot be installed on Recovery HD.
    2. Verify and Repair the disk and I errors but it cannot fix them. Some are:
                   'invalid leaf count''
                   ''missing thread record''
                   ''incorrect number of file hard links''
                   ''overlapped extent allocation''
              and it finally says ''the volume Macintosh HD cannot be repaired'' Error: ''Disk Utility can't repair this disk.. disk, and restore your backed up files.
    I would like to know a way to back up my files so that i can completely restore the disk without any data loss as I havent backed up for a while!
    If anyone has any solution to this issue it would be much appreciated!

  • Disk Utility can't repair disk

    Hi, I just saw that the amount of memory left on my HD just dropped around 60GB, so I used the "Verify Disk" option on Disk Utility, and the output was:

    Error: This disk needs to be repaired. Start up your computer with another disk (such as your Mac OS X installation disc), and then use Disk Utility to repair this disk.
    I don't have the disk right now, so is there some other way I can repair it, get another install disk, or anything else? I've been thinking of booting up with a Linux livecd, but can it access the HFS+ filesystem?
    Thanks.

    Try this: from http://support.apple.com/kb/TS1417
    Start up your computer in single-user mode to reach the command line.
    Note: If necessary, perform a forced restart as described in the Emergency Troubleshooting Handbook that came with your computer. On desktop computers, you can do this by pressing the reset/interrupt button (if there is one) or holding down the power button for several seconds. On portable computers, simultaneously press the Command-Control-power keys. If your portable computer doesn't restart with this method, you may need to reset the Power Manager.
    At the command-line prompt type:
    /sbin/fsck -fy
    Press Return. fsck will go through five "phases" and then return information about your disk's use and fragmentation. Once it finishes, it'll display this message if no issue is found:
    ** The volume (name_of_volume) appears to be OKIf fsck found issues and has altered, repaired, or fixed anything, it will display this message:
    ***** FILE SYSTEM WAS MODIFIED *****
    Important: If this message appears, repeat the fsck command you typed in step 2 until fsck tells you that your volume appears to be OK (first-pass repairs may uncover additional issues, so this is a normal thing to do).
    When fsck reports that your volume is OK, typerebootat the prompt and then press Return.
    Your computer should start up normally and allow you to log in.
    If you can't find your original install disk, you could always buy another Snow Leopard disk. It's only $29.

  • Lion Install thinks that the system disk "Macintosh HD" is not Mac OS Extended (journaled); it is. Exactly what do I do in Disk Utility to "reformat" the disk, I don't see that listed on the menus.

    Error Message, during installation of Lion; “This disk is not formatted as Mac OS Extended (journaled). Use Disk Utility to enable journaling or reformat the disk.”  The disk I selected to install OS X on, was the only one listed, “Macintosh HD”. The results of a Disk Utility check are; Format: Mac OS Extended (journaled), Name: Macintosh HD. There is a fresh Time Machine backup. The computer was Restarted and installation attempted again - same result. I have downloaded Lion a second time, and tired install again, same results. The computer is a December 2007, iMac 24” with 2.4 GHz Intel Core 2 Duo, 4 GB Memory, s/w version 10.7.5; Disk Capacity 319 GB, Available 117 GB. Macintosh HD has alway been the system disk, does it now have an identity crisis? Would reformatting the disk mean Erasing it? Exactly what do I do in Disk Utility to “reformat” the disk, I don’t see that listed on the menus. This computer is getting cranky, I no longer Shut Down at night, only Sleep. If it’s Shut Down, the next morning I am treated to a white screen, for a long time, before it finally shows me the Log On Screen.  Suggestions would be appreciated.

    RRFS - This took me a long time to finally get to a fix. Your reply led me to investigate the Repair Disk Partition - as it turned out there wasn't one; the HardDrive was going bad slowly. The 10 to 40 minutes it took to startup in the morning, was the HD trying to find it's way. I had the 320GB HD replaced with a 2TB HD. All is OK now. Thank You very much!!  Also, the Apple store geeks couldn't make it better but the locally owned Apple retailer did just great with it. from San Luis Obispo County - Peace.
