Increase startup disk partition size

Greetings,
I need a simple way to increase the size of my startup drive.  Currently my SSD drive has 2 equal partitions of approximately 250GB.  The top partition has no data or applications, it is empty and can be eliminated.  The lower partition is 95% full with applications only.  The operating system is 10.8.5.
Can I simply copy everything from my Home Folder (all my applications and operating system) to a secondary drive, then reformat the impacted original startup drive to one partition, then copy the Home Folder back?  Will the operating system work properly?  Will applications work properly?  Sorry for these basic questions, but I would sincerely appreciate any knowledge on this topic.
Thanks, Scott

Use a program such as the Disk Utility, Carbon Copy Cloner, or SuperDuper to clone the contents of the bottom partition to the top one, restart from the top one, delete the bottom one, and then resize the remaining partition to the size of the drive.

  • Increase System Volume/Startup Disk Partition Size

    Hi,
    I don't know much about Macs or OSX so bear with me.. I have been searching for a simple way to increase the size of the System Volume on my daughters MacBook running Maverick. She keeps getting a warning to say that the start-up disk is full or nearly full. I have used drive magic to clear some of the temp files and also used monolingual which has helped.
    The trouble is that the System Volume only has 74 MB of free space whilst the User Data partition has 172GB of free space. I have tried to clean the disk using utilities and have moved the User folder to the User Data partition but that is not really helping..
    Is there a way to expand/extend the System Volume area so that it doesn’t constantly run out of space without losing the User Data?
    I can’t update applications because if I try I get told there is not enough disk space available…
    I have uploaded some screenshots that may help:
    System Volume:
    https://dl.dropboxusercontent.com/u/7548959/sv.jpg
    User Data:
    https://dl.dropboxusercontent.com/u/7548959/ud.jpg
    If there is some software that I can purchased that could be used to do this then let me know.
    Cheers
    M

    Everything there looks ok in that screenshot (I was looking to see if there was any [Backup] data, but you only have 400MB in the User Data partition)
    I would suggest that you just have one partiton (usually named Macistosh HD, but you can name is anything you want. (Is there a reason why you have it partitoned this way?)
    To expand the System Volume partiton, you first need to delete the User Data partiton.
    BACK UP ALL DATA
    Copy all files from the User Data Partion to an external HD (or flash drive)
    In Disk Utility, select the Partiton Tab, click the User Data Partiton and click [-] to Remove
    Drag the Right Corner of the System Data partiton to expand the partiton
    OPTIONAL
               a) Click [+] to Add Back the User Data partiton
               b) Move the slider between the partitons to re-size
        6. Click [Apply]
        7. Copy back the User Data from the External Drive (or flash drive]

    Done. Thank you, Allan.
    The sparse image article you sent a link to needs a little updating (or there's some variability in prompts (no password was required) with my OS and/or Disk Utility version), but it worked.
    Phew! It would have been much more time consuming to use Time Machine to recover all my photos after repartitioning the drive. 

  • Hard time for selecting Startup Disk (partition) in Mac Classic II.

    Dear coleagues, I'd like your help to understand and solve a tricky trouble. I'm sorry for the long text, but the issue is probably living in a small detail.
    The issue regards a Mac Classic II with internal and external HDDs. Internal HDD has two partitions, a smaller with System 7.1 (first) and a larger with System 7.5.3 (second). This one is installed there since 5 years ago, working fine.
    The (just installed) external HDD has 6 partitions (because of its size 9 Gb). It has been formated runing VCP in this Classic II itself and all partitions are initialized with HFS. It is intended to be a backup for my Classic II as well as my Mac Plus. I've started Installing System 7.5.3 in its third partition. Other partitions remain still empty.
    Using only internal HDD I can already perceive that "Startup Disk" control panel is unable to change the boot partition attribute between partitions in the same drive. When I open "Startup Disk" it usualy both partitions of internal HDD are highlighted. I can select a Zip Drive, for instance, and it will boot from Zip. But, when I switch it back to HDD, doesn't bother wich partition I select, it will always boot with the same partition (usually 7.5.3). Then, If i open Startup Disk CP again, both partitions are again highlighted.
    To switch between partitions in the same drive, I use Lido 7.5.6 PMount and there I select the boot partition. Then every time I select my HDD, that'll be the default boot partition.
    My conclusion is that in Mac Classic II the Startup Disk CP is unable to set a partition within a drive, it selects the drive only. The boot will obey the drive's partition table flag. That's why I can do it whith Lido, writing directly at HDD's flags.
    Now, attaching the external HDD, I can see all its partitions in Startup Disk CP and then I select one of them (the 3rd, with 7.5.3). Before rebooting, I close and open again the Startup Disk CP, then I can see all its 6 partitions highlighted. Just like I've been doing with the internal HDD, probably the solution to set a specific boot partition would be through Lido 7.5.6 PMount again. But Lido is unable to handle this drive. It appears gray in the drives list.
    What does it sound to you? What would you recommend to test? Is there an alternative for Startup Disk CP?
    Thank you.
    Regards, Ciro (Brazil)

    Dear Jan, good Evening.
    Thank you for your time.
    In fact I can select a specific partition, but by closing and reopenning Startup Disk CP I realize that the selection has been attributed to the physical drive (all partitions highlighted).
    I have tried Startup Disk CP in both System 7.1 and System 7.5.3. They do the same way.
    Internal HDD has been formated, partitioned and initialized with Apple HD CS Setup.
    This external HDD in a different way. Apple HD SC Setup hasn't been able to "see" it, probably because of its prior format system. Lido neither. That's why I went to VCP. Moreover, as it is too big for 68030, I had to format it attached to a Performa 6360. After formating, I've let VCP make set the partitions in HFS mode (partitions with 512, 1024 and 2032 Mb).
    I've mounted VCP in Mini VMac to get some screenshots for you:
    Bringing it back to Mac Classic II, it could be mounted with Lido, but System 7 has asked to initialize all partitions again. I've accepted, installed system 7 on it, and it didn't boot. Then I've repeated the partitioning and initializing procedures using Apple HD SC Setup (since now there's a Mac HDD with "small" logical drives). Nothing changed.
    I'm following your tip about System Picker. I've downloaded the sit file and read about it. It seems to be able to overlay the problem. I'm gonna try it and report back here.
    But I feel still uncomfortable not to be able to do things the regular way. As far as I know, the boot partition is an attribute of a drive partition in partition map, just like the "Active Partition" found in FAT systems. I should be able to write there as I can do with Lido in internal HDD.
    Thank you, Jan.
    Best regards,
    Ciro Bruno.

  • Need to increase startup disk memory

    My hard drive is full so I installed the time machine so I can backup my files.
    Now, i frequently get a message that i need to make more space for my startup disk.
    How can I safely make space and what are some of the files or application I can remove to increase space?

    Well, you're addressing two separate issues here. First, running backups with Time Machine is very sensible, but do understand that it's intended as a backup, not an archive. That is, you should always have two copies of your files - the original, and the backup. Therefore, don't delete any important files from your main drive, since you will then only have one copy (which is NOT a safe backup!)
    Second, your hard drive space. How large is your current drive? You may benefit from simply installing a larger drive. It's a technical operation on a PowerBook, so you may want to find a local tech if you're not comfortable disassembling your Mac. If you don't want to take that step yet, run OmniDiskSweeper to find out which files and folders are taking up the most space. If you have iDVD and/or GarageBand installed, and don't use them, you can remove their large template/loop files from the /Library/Application Support folder. You might also shave off a couple of GB running MonoLingual. But these are really stopgap solutions, and ultimately, a larger HD may well be the solution.

  • Disk Partition Sizes - Best Practices

    In the old days of SunOs 4.x we used to spend a lot of time figuring out disk slice sizes to make sure that we maximized the space on the old 200 meg disks.
    Then once we started using the 1 to 4 gig disk we used just make it one big slice and not worry about things filling up because when it was full, it was full.
    Now, we have these huge 32 gig to 100+ gig drives and things become tricky again. I was wondering how other large companies are slicing up their drives and what thie best practices are.
    The size I was interested in were for:
    8,18,36,72,146 G disk
    My thought is that the 8 gig is still small enough to do the complete disk, but the others may need some thought.
    If some people could let me know what they do for:
    /var
    /opt
    /usr
    I know that we should handle non DB machines different than DB machines so any advice on that would be great.
    Thanks in advance.

    well normally when I setup systems I don't like /usr or /var or anything so I lump everything into root "/", since you don't have any other filesystems your space dun get "locked" and wasted it also makes it easier to do manual backups like ufsdumps also.
    But if you do want to partition the exception would be /var and /opt as a lot of patches and software normally defaults to these 2 as the base installation directory but as I said normally I throw everything into "/".
    Then there's slice 2, 3, 4 and 7 which normally I don't install anything on them
    slice 2 is "backup" represents the entire disk, it can be used but normally nobody touches this. if you use it, I think there will be a problem if you wanna do things like 'dd'
    not sure now but In the old days when you used things like volume manager, vm will take slice 3 and 4 as a private/public region if you have data on it prior to encapsulation it will move the data to other slices for you, but if there are no free slices to move data to from slice 3 and 4 then vm install will fail or if you want to unencapsulate the rootdisk later on you will have a confusing problem as orignally your data from slice 3 and 4 was moved elsewhere during vm encapsulation.
    slice 7 by default with I first install os I will either leave it blank for future or allocate 10mb to it, this is in case I wanna mirror the disk using disksuite so I normally designate slice 7 of all the disks as my metadb, if you use up all the space and leave slice 7 blank you can still allocate space to it for metadb by allocating a few sectors to it from the "swap" area in cdrom single user mode.

  • Startup disk partition map repair difficulties

    Disk Utility is reporting that "The partition map needs to be repaired because there's a problem with the EFI system partition's file system." However, after booting into the Recovery HD and attempting to repair this, I keep getting the error, "Live file system repair is not supported." And yet I can verify that I am definitely not booting from the startup disk so I don't know why or how this is happening. Any ideas on next steps short of backing up, reformatting and wiping the drive?
    Thanks in advance for any guidance!

    Hi Richard,
    If you are having issues resolving a disk issue when booted to the Recovery partition on the internal hard drive, especially issues regarding partitions themselves, you may want to try creating a Recovery System on an external volume, as outlined in the following article:

  • Increase external drive partition size

    I partititioned a portable drive into 2 equal sizes  MAC OS Extended (Journaled).  Is there a way to resize these drives after they are done.  I can't seem to figure it out under Disk Utility.  Thanks.

    It appears i am out of luck.  The bottom partition  is a time machine backup.  The top is just data.  I wanted to reduce the top and increase time machine.  Is there a way to temporarily move TM backups and then reformat drive?   Simple as copying to HD then a reformat of the portable HD?
    That will work, but a much better solution is to back up to a separate external HD.
    If you do that, then you can also back up the other partition on the current drive, along with your internal HD. 
    If you want, you can copy the backups to the new drive, via the Restore tab of Disk Utility, or the Finder.  Or, let Time Machine start fresh on the new drive.  You can always view and restore from the old ones, per #17 in Time Machine - Frequently Asked Questions.  When you don't need them anymore, just erase the partition.
    To copy them, see section 1 in #18 of the FAQ.

  • INCREASING RECOVERY DISK PARTITION

    HI, New to this forum and was wondering if anyone can help me; I have a refurbished HP Pavilion DV6-6c35dx laptop and everything is running great for now. The problem i am having is that i have only 1.43GB of free space on my recovery partition and i need to now if it is safe to increase the size of it using either the Windows 7 disk management or i do have the free edition of EaseUS Partition Master Home Edition program. The partition that i will be allocating the space from is my C: Main Drive; it has 393.17GB of free space available.
    Thanks for any help with this.
    Mike

    The recovery partition shouldn't really be adjusted.  If it is, then there is a good chance that the the F11 recovery, should you ever need to reinstall the original OS and software it came with, won't function. 
    If you need more space to store files, I would advise looking into other storage options such as an external drive.  The recovery partition will intentionally have just enough room for the recovery files and not much extra beyond that.  This is by design. 
    Good catch on the system protection option.  That is actually quite common and it eventually results in the drive being marked as nearing full capacity and then Windows displays a frequent message about it which can be a nuisance.  It's common enough for there to be an HP document regarding it.

  • How to Increase disk image size of SAM

    Hello,
    I am trying to increase the disk image size. I am trying to increase to about 6G, but SAM just refused to load the image.
    So, is there a limit in SAM about the virtual disk size? Or is it limited to the physical memory of the system?
    I have read the thread http://forums.sun.com/thread.jspa?threadID=5239257&tstart=30 and http://forums.sun.com/thread.jspa?forumID=837&threadID=5286038 about enlarging the disk image.
    I am using OpenSparc T2 Arch 1.2 and the int12 boot bundle. I am wondering if I should change to the sasdisk for a try.
    It is strange, that I previously ran the simulator on a Solaris Express (actually 5.11), and it worked fine.
    But now I changed to the Solaris 10, then it failed.
    Thank you.
    Jim

    As it turns out, the way to make the image appear larger on the page is to edit and increase the size of the signature "box" on the pdf (under Forms > Add or Edit Fields), to considerably larger than the form might indicate.  Otherwise, the signature is constrained to the just the size of the small field on the pdf.  Interestingly, as soon as you do so, the signature appears "bolder", likely just because there is more of it.  Thanks for your suggestions!

  • Mac Mini 10.6 Server startup disk size increase problem.

    Mac Mini 10.6 Server shows system startup disk sized 50GB with 20GB free. Disk utility shows partition sized 500GB with 470GB free. How can I increase size of startup volume without complete reinstall?

    Is the disk partitioned?
    Boot the operating system DVD, use Disk Utility from the Utilities menu (second screen of the installation process, just before you start the actual install) to ake a complete backup to an external disk, make a second backup (in case there's a problem with the first), wipe and repartition the internal disk (using Disk Utility), and reload.
    You'll want to consider whether you want to mirror the two disks within the box, too; to set up RAID-1 across both of the 500 GB drives in the box.  That mirroring can be established when you're wiping and repartitioning the disks.

  • Trying to get rid of error "The startup disk cannot be partitioned or restored to a single partition". Recovery HD visible.

    Hello,
    I've been stuck for some hours now trying different things to install Windows 7 on my Macbook Air, and I think now is the time to call for some custom help.
    I'm using OS X 10.9.5 Mavericks.
    So some months ago I just wanted to run Linux on my laptop so I installed rEFInd, shrunk the Macintosh HD partition by 25GB and booted on a linux live USB flash I burned using dd.
    Then I used gparted to create my linux partitions.
    It worked just fine, even though disk utility from OS X seemed quite unhappy about this (it seemed to have incorrect informations about the filesystem on these partitions, seeing them as journaled Mac OS while they were clearly not). At this point already, the Recovery HD from mac showed up in disk utility, which I found weird but didn't bother me.
    But recently I needed windows on my Mac. So after a few tries for the triple boot, I managed to create a bootable USB stick with boot camp, which already showed me the message "The startup disk cannot be partitioned or restored to a single partition" and hence refused to partition/install himself.
    So I thought "OK, that's no big issue, I can just partition with disk utility and then boot on the USB stick and everything will work fine". But when EFI booting on the USB flash drive I got stuck at the beginning of Windows installer with no keyboard or mouse support.
    After some hours spent googling, I was unable to find a working fix for that, and as there was no support for my case (where I used bootcamp to create the bootable flash but NOT to partition/reboot) I decided to give bootcamp a try.
    So I erased my linux partitions, and cleaned up everything I could on the HD with disk utility. That means I now have two partitions showing in disk utility : Macintosh HD and Recovery HD.
    When using disk utility from terminal, the list is :
    /dev/disk0
       #:                       TYPE NAME                    SIZE       IDENTIFIER
       0:      GUID_partition_scheme                        *121.3 GB   disk0
       1:                        EFI EFI                     209.7 MB   disk0s1
       2:                  Apple_HFS Macintosh HD            80.0 GB    disk0s2
       3:                  Apple_HFS Recovery HD             650.1 MB   disk0s3
    But boot camp still isn't happy, and the message "The startup disk cannot be partitioned or restored to a single partition" keeps popping after the intro and I can't partition/boot from bootcamp.
    So, as I don't understand what is wrong here anymore, any help would be greatly appreciated!
    I will be watching the thread a lot because I really would like this resolved (or windows installed one way or another) this weekend; so any questions on my past manipulations or config just ask!
    Thank you.

    keyboard issues are also something of a common issue.
    I wish the best threads were voted to the top of forums, something! Me, I literally burned out here, but after installing 10 Preview, wanted to "see what was going on" after hiatus of a couple years and see if anything had changed (no, not really!)
    Also, these new Communities are not putting "more like this" and failing to help too.
    I think rewriting Boot Camp Assistant's built in help and pdf would help a lot, and needs to be clearer and go into details. And Yosemite was not it seems tested against Boot Camp, and drivers for new Macs + new OS also lag behind. Again, common and no sign of improvement or change.
    One of the tricks to the "can't partition" is rather simple - of course backup is step #1 and is spelled out - SHRINK the main HFS+ partition! then stretch it back to full length. Sometimes a reboot is needed, and sometimes even do a Safe Boot - not sure what but Recovry Mode might be a good option too. That does seem to consolidate free space, move files that are locked and cannot be moved otherwise, and allow BCA to partition, jusst be sure to have enough space left and large enough for a proper Windows install (and fudge factor).

  • I'm getting this error with bootcamp "The startup disk does not have enough space to be partitioned"

    Here's the story...
    I had a dual boot configuration on my mac with Mac OS X Lion and Windows XP (made with bootcamp).
    I decided to reinstall windows.
    I deleted the windows partition using BootCamp.
    Tried to recreate the Windows partition with Boot Camp and got: "The startup disk does not have enough space to be partitioned  You must have at least 10 GB of free space available"
    After reading several posts on this forum I decided to defrag the hard drive and try again. 
    The defrag did not work and I'm still getting the error, I have 22 gb of free space on my drive.
    Any suggestions?
    Also, I tried repair disk and repair permissions
    Hmm, my external harddrive says on the box "OS X 10.5.8 or higher (32-bit kernel only)"  Could the 32-bit requirement be an issue? Is lion 64-bit?

    Boot Camp must be able to allocate a contiguous block of space on the drive. If it cannot find 10 GBs of contiguous space, then you cannot create the Windows partition.
    You will have to backup your OS X partition to an external drive, boot from the external drive, use Disk Utility to repartition and reformat your hard drive back to a single volume, then restore your backup to the internal hard drive.
    Get an empty external hard drive and clone your internal drive to the external one.
    Boot from the external hard drive.
    Erase the internal hard drive.
    Restore the external clone to the internal hard drive.
    Clone the internal drive to the external drive
    Open Disk Utility from the Utilities folder.
    Select the destination volume from the left side list.
    Click on the Restore tab in the DU main window.
    Check the box labeled Erase destination.
    Select the destination volume from the left side list and drag it to the Destination entry field.
    Select the source volume from the left side list and drag it to the Source entry field.
    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
    Open Disk Utility in your Utilities folder.
    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.
    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
    Select the destination volume from the left side list.
    Click on the Restore tab in the DU main window.
    Check the box labeled Erase destination.
    Select the destination volume from the left side list and drag it to the Destination entry field.
    Select the source volume from the left side list and drag it to the Source entry field.
    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.
