On Partitioning, Error telling to Format disk

Hi! I recently upgraded my previously Tiger Macbook Pro to Leopard over the weekend and decided to install a boot camp partition now that it came free with the new OS. After selecting my size and letting it load for a bit, I received this error:
"Back up the disk and use Disk Utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using Boot Camp Assistant again."
I don't understand this because according to Disk Utility it is Mac OS extended journaled. I'm not very experienced with this error but it didn't happen when I installed XP on my iMac. What can I do to install my boot camp partition?
Thanks,
Ian

hey there
i just had to do the same thing. back up the disk, time machine is really convenient. mine appeared to be formatted correctly too.
i eventually backed it up and reformatted the hard drive with the installer disk that came with the computer. then i restored from the time machine and partitioned the hard drive; it worked.
i'm still having problems because of xp "disk error" issues, but there's a bunch of threads on that here already.
i don't know what causes the error. but as long as you can back up your data, just follow the prompts and it should work

    My macbook air (OS x lion ) hard disk got crashed. now it starts with a grey screen and MAC OS X utilities. in the disk utility, the hard disk icon became inactive. when i erased the disk it became active again but i am still not able to partition it. it showed -- "Partition Error". "Couldn't unmount disk". now the disk icon became inactive again. when i click on mount it becomes active again but partioning is not done after many attempts.

  • Partitioning error in bootcamp

    also why do i get a partitioning error that says "The disk cannot be partitioned because some files connot be moved"
    the seubtext says "Back up the disk and use Disk Utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using Boot Camp Assistant again."
    ps sorry about the link, its the only way to copy and paste

    It means one of two things:
    1. You are trying to create too large a partition and are running into a part of the drive OS X is currently using.
    2. Your request needs contiguous space, but the drive is slightly fragmented and Boot Camp Assistant cannot allocate the amount of contiguous space requested.
    You can try configuring a smaller Windows partition if that's feasible. Otherwise, you need to defragment your hard drive.
    Defragmenting a Drive
    1. Get an empty external hard drive and clone your internal drive to the external one.
    2. Boot from the external hard drive.
    3. Erase the internal hard drive.
    4. Restore the external clone to the internal hard drive.
    Clone the internal drive to the external drive
    1. Open Disk Utility from the Utilities folder.
    2. Select the destination volume from the left side list.
    3. Click on the Restore tab in the DU main window.
    4. Check the box labeled Erase destination.
    5. Select the destination volume from the left side list and drag it to the Destination entry field.
    6. Select the 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.
    Destination means the external backup drive. Source means the internal startup drive.
    Restart the computer and after the chime press and hold down the OPTION key until the boot manager appears.  Select the icon for the external drive and click on the downward pointing arrow button.
    After startup do the following:
    Erase internal hard drive
    1.  Open Disk Utility in your Utilities folder.
    2. After DU loads select your internal hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area.  If it does not say "Verified" then the drive is failing or has failed and will need replacing.  SMART info will not be reported  on external drives. Otherwise, click on the Partition tab in the DU main window.
    3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.  Do not quit Disk Utility.
    Restore the clone to the internal hard drive
    1. Select the destination volume from the left side list.
    2. Click on the Restore tab in the DU main window.
    3. Check the box labeled Erase destination.
    4. Select the destination volume from the left side list and drag it to the Destination entry field.
    5. Select the source volume from the left side list and drag it to the Source entry field.
    6. Double-check you got it right, then click on the Restore button.
    Destination means the internal hard drive. Source means the external startup drive.
    Note that the Source and Destination drives are swapped for this last procedure.

  • BootCamp Assistant Error : Your bootable USB drive could not be created. "An error occurred while formatting the disk."

    I have a Windows 7 Ultimate .iso file saved onto a "Mac OS Extended (Journal)" formatted USB flash drive. I am trying to install it with BootCamp Assistant and I keep getting the error message : Your bootable USB drive could not be created. "An error occurred while formatting the disk."
    I have previously installed Windows 7 on my Mac (and it worked flawlessly - same .iso file), but I uninstalled it because I didn't partition enough space on my hard drive. I have used several flash drive to try and install and none have worked.
    Some help would be greatly appreciated.

  • Can I format only one partition on an external hard disk?

    I have partitioned my external Hard drive into three different partitions, each of different formats. Two partitions for backing up my macbooks and one to copy to and from my windows PC. I would just like to know if in any way is it possible for me to be able to re-partition one of the partitions, without affecting my Time machine partitions, in case the need be in future.

    Yes, provided the partition has sufficient free space.
    Open Disk Utility, select the drive's main entry in the list then click on the Partition tab in the main window. Click in the partition you wish to change, then click on the Add [+] button. The partition should divide in half. You can the resize as you need. The blue area you see in each partition represents what is in use. When you have it as you want click on the Apply button.

  • Help needed with delete of bootcamp partition, error message 'Couldn't unmount disk'

    Hello all
    Sorry if this issue has been repeated elsewhere, I did search but there wasn't a discussion relating to my specific issue.
    When we bought the iMac a couple of years ago, my husband partitioned the hard drive to run Windows via Bootcamp. Having got used to the Mac and experiencing the frustration between having to reboot to access each partition I have decided to restore the Mac to factory settings and install Parallels 8 so I can continue to use Office and Coreldraw).
    So having backed up all of my files, I started the Mac up holding the 'Alt' key and then loaded the Recovery HD mode followed by Disk Utility. I then selected Bootcamp and erased all data from the partition. [Note: there are 2 files left which it won't allow me to erase through this method]
    I then selected the main drive and the tab 'Partition', from the layout I then selected Bootcamp and clicked the minus button. I get the message confirming which partition I am about to delete and hit remove. I then get the error message 'Partition failed: couldn't unmount disk'.
    I would be very grateful for some help please? I am not the best techy person but happy to give anything a go.
    Just to mention there is nothing left on the Mac that I want to keep, therefore if there is an easier way than having to delete the partition then happy to hear it.
    Thanks

  • Partition Error - target disk too small

    On my 3.1Ghz iMac running OSX 10.8.5 I'm trying to Partition my Hard drive so I can setup a second boot.
    Currently my Macintosh HD has 404.07GB USED and 707.75 AVAILABLE.
    I'm trying to add a partition that is about 350GB.  But when I do so, it gives an error that the Target Disk Is Too Small.
    Why is this?  How can I get around this?
    I have included screenshots from my Disk Utility:

    You can't resize a Core Storage logical volume. You would have to start up in Recovery mode and destroy the logical volume group (also destroying all data in the process), partition, and then restore the data from a backup. Almost certainly this is not a good idea unless you need to dual boot, but that wasn't your question.

  • Stumped On How To Fix HFS+Partition Error!! Help!

    WEll hello and i am having so much trouble with my mac software. My current setup is as follows.
    -Windows XP Home Edition Installed As Base OS
    -80GB Hard Drive Partitioned
    -65GB Windows NTFS Partition
    -15GB Mac Partition
    -Intel Celeron Processor
    -Multiboot Software Set Up As Well
    Here's my problem. I made all the partitions correctly and installed the Mac software onto my pc with already had Windows XP installed on it. The install went smoothly and the disk was mounted and formatted correctly. But after the install of the Mac OS I restart my pc and boot into Mac. Immediatly a message comes up saying HFS+ Partition Error. I have tried tons of things to fix it but everywhere I go it tells you have to fix erros related to intalling Windows onto a Mac. But luckily my Windows Xp still boots up fine. Someone out please help me!!
    Great appreciation if ya do

  • Is my HD Dead? Reformat Disk Utility Error: secure disk erase failed with the error could not open disk.

    Hi,
    Fed up with seeing the spinning beach ball I decided to reformat my MacBook Pro...
    After backing up everything on an external hard drive I put in the OSX install DVD, restarted the machine and held down 'C'.
    I followed the install prcedure, clicking next a few times etc...
    I then went into Utilities > Disk Utility. I chose 7-Pass to erase the Macintosh HD and set it off erasing.
    I checked the process an hour in and message on screen read:
    Secure disk erase failed with the error:
    could not open disk
    The internal hard drive no longer exists in the disk utility so I cant retry erasing it.
    The only thing that appears in disk utility is the OSX install DVD.
    I can't even shut down the mac as everything under the apple tab is greyed out!
    I'm guessing this means my hard drive is broken right?
    If anyone has any other ideas of what to try I'd really appreciate that.
    How do I turn the machine off?
    If my hard drive is gone then should I consider getting an SSD drive?
    Any recommendations for such a drive would be great.
    Hope you can help!

    Did you partition the drive?
    Extended Hard Drive Preparation
    1. Open Disk Utility in your Utilities folder. If you need to reformat your startup volume, then you must boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger or Leopard.)
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
    3. Click on the Options button, set the partition scheme to GUID (only required for Intel Macs) then click on the OK button. Set the number of partitions from the dropdown menu (use 1 partition unless you wish to make more.) Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the volume(s) mount on the Desktop.
    4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
    5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
    6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
    Steps 4-6 are optional but should be used on a drive that has never been formatted before, if the format type is not Mac OS Extended, if the partition scheme has been changed, or if a different operating system (not OS X) has been installed on the drive.

  • SL install error: "Can't use disk to start up"

    I've spent some time searching the forums but haven't come across a solution that works yet. I currently have 10.5.8 and have a family pack for SL. I've installed it on a 24" iMac just fine and a 17" MBP. I'm now trying to install on a 15" late-2008 MBP and am getting the error that says snow leopard can't install to my Macintosh HD because that disk can't be used to start the computer. That's funny because it seems to be able to start just fine and I'm not experiencing any nagging issues with my Leopard install. I'll mention that I use Boot Camp and have a Win7 partition on the same drive.
    Per one of the other posts I've tried the following:
    1. Zap the Pram- No change
    2. Resize Mac partition- Disk Utility won't let me change the Mac partition for some reason. It says that it needs to be HFS+ Journaled, which it is. That's a bit confusing.
    3. Repair Permissions- I've repaired permissions on the Mac HD, but no change. I've heard that I need to repair permissions at the root drive level in Disk Utility, but when I click on the "whole drive" icon, Repair Permission is grayed out.
    For insurance sake, I've cloned both my BootCamp partition and my Mac Partition ( I also have an up-to-date TM backup and everything's backed up to Mozy as well). So I could format the drive and try a fresh install of SL. Then I would have the choice of using Migration Assistant or something of the like to pull in apps and Docs from TM right? I don't mind doing a fresh install but it would certainly save time to simply upgrade.
    Are there any performance issues that I might encounter by using Migration Assistant to pull the info from my TM backup?
    Any way to address the issue so I can do a simple upgrade?
    Thx.
    Jonathan

    When I look I see GPT/GUID 200MB partition, then one 128MB, followed by HFS+, and a second 128MB at the end.
    Maybe things have changed and the docs on rEFIt doesn't acknowledge Apple's use of UEFI 2.x that began in 2008.
    Quote from their web site:
    *Myth: Mac OS X requires GPT*
    +This is mostly a myth. Mac OS X boots and runs just fine from disks using MBR partitioning, or even APM (Apple Partition Map, used on PowerPC Macs).+
    +However, the Mac OS X Installer will refuse to put a fresh copy of Mac OS X on a disk that’s not using GPT. You can work around this using cloning tools like SuperDuper! or Carbon Copy Cloner. Install Mac OS X on a GPT-partitioned disk first, then clone it onto the disk of your choice.+
    +Apple’s firmware updates are another issue. The exact requirements are not known at this time, but they are known to not work if you don’t have GPT and you don’t have a EFI System Partition.+
    +Myth: Mac OS X requires a hidden EFI System Partition+
    +Every GPT-formatted disk is supposed to have an EFI System Partition, and Apple’s tools create one at the beginning of the disk. However, Mac OS X doesn’t actually use it; the EFI System Partition is completely empty on a standard Intel Mac. Apple has added a HFS+ file system driver to its firmware, and the firmware boots Mac OS X directly from the partition it is installed on.+
    +Also see above; Mac OS X can boot from a MBR-only disk with no trace of an EFI System Partition.+
    +There is still some uncertainty about firmware updates, though. So far no one has investigated how they work in detail, and some people believe they require the EFI System Partition to be present.+
    +Myth: EFI requires GPT+
    +The GPT specification is part of the EFI specification. However, all parts and features of EFI are just as well-defined for MBR-partitioned disks.+
    http://refit.sourceforge.net/myths/
    I've never used rEFIt but obviously seen it discussed and used a number of times.

  • GPT partition error

    My laptop is Hp pavilion 15 . The original system is windows8 which is already installed.
    But i formatted the disk c where the windows installed while installing the windows 7 just because flashing the desktop . But i cant install the error becomes "The Selected disk is of the GPT partition style" . Then i inserted the windows 8 cd the Same Error became.
    So Anybody can tel me What can i do now?
    I have no windows in my latop

    Thanks for the idea of booting in EFI mode. After looking around, though, it seems that I read as many "it didn't work/screwed up my drive" complaints as successes. Since I really know so little about it, I'm not that comfortable just trying to muddle my way through it. I'll keep looking into it though.
    Should I gather at this point that the real problem is that BootCamp doesn't work correctly on Fusion Drives, or it's possibly a Mavericks or Windows 8 problem, and people here are just coming up with workarounds until Apple fixes it? Or is everything fine as far as Apple is concerned? I know I had no trouble installing BootCamp on my previous computer, a mid-2010 iMac running Mountain Lion and Windows 7.
    Unfortunately, the Windows 7 I have is an upgrade from XP, and the BootCamp/Mavericks documentation said I couldn't use an upgrade, so I went out and bought Windows 8. Hate spending money on Windows, but especially when I can't use it!
    Any other suggestions to get BootCamp up and running would still be appreciated!

  • Boot/Partition Error

    After partitioning my hard drive, first using Disk Utility and then GParted (to change the format of this new partition to something besides Mac Extended Journaled) and then an incomplete install of FreeBSD onto this new partition (note, the partition containing my OS X still worked fine until I began the actual installation of FreeBSD) my MacBook will not boot. Using ubuntu LiveCD, I was still able to mount the partition containing OS X and explore the file system, and all the files were still there; however, it seems the boot partition has some error with it, and also the OS X partition has lost whatever makes it able to be recognized by OS X's Disk Utility.
    If I boot to the setup DVD for Leopard, the Disk Utility does not even recognize that there is a valid Mac (hfs+) formatted partition on the hard drive, though it can find a second partition which should be listed as unallocated space.
    Is there any way to simply fix the boot partition and make the valid hfs+ partition recognized again without formatting and making a clean install?

    I have the rEFIt boot utility installed, which blocks the automatic EFI boot of OS X and allows you to choose boot options. Apparently, the problem with the boot partition was that it wanted something to be in the unallocated space (the mysterious second partition) when there wasn't anything. I just did a basic install of ubuntu Linux onto the free space (giving it a partition and OS where it wanted one) and everything works fine again.
