Resizing an existing partition

I have cloned my old SATA disk to a new bigger one.
But when I booted, I did not see the extra space on the disk. I then used the Disk Utility to try to increase the partition. In the partition window, I saw the full capacity of the disk and also that the partition was as the size of the old disk. I dragged out the partition and the pushed the key to use it. After a while I got an error message from the mediaKit about that the "partition (map) was to small".
The second trial was to add another partition in the free space, which seemed to work until I started the partitioning. After a while I got another error "The selected size is not valid for the selected file system"
Any ideas?

Yes, that must be the equivalent of "Journaled."
This disk is a new disk which i have cloned from the original disk that was installed when I bought my MacBook. The new one is twice as big as the original one, but it seems that there are some information somewhere on the disk, which make DU to think it is just half the size. Although when I select the disk in DU, it displays the right size and it seems to work to add an extra partition in the empty space using the same format as partition 1 (MacOS ...), but when hitting the Use key, I get the error message after a while
It sounds like it has the wrong +Partition Map Scheme,+ but if it did, it wouldn't start up your Mac.
Or is it an external? If it's an external, select the top line for the drive, and see what it shows at the bottom of the window:
It should be GUID, like the sample.

  • Cannot resize Time Machine partition

    Hello all,
    I currently have a hard drive split into 2 partitions (both Mac OS Extended (Journaled)). One of the Time Machine partitions is far too big (for the backups it contains) and I want to reclaim some space as a regular data partition (for my windows PC). Unfortunately I can find no way to resize the existing partitions. There is no "corner to drag" in my disk utility. 617GB are free in the 697GB partition.

    Time Machine likes to be the first partition, otherwise it will continually ask you where?

  • How do you resize existing partitions on an external hard-drive without deleting their contents?

    Hi, I've got an external hard drive (1 GB Western digital) Which I bought with a view to both storage and time-machine functions.
    Initially, I partitioned the hard drive such that I had 750 GB for the time-machine segment, and 250 GB for the storage segment.
    Now that my storage is approaching the 250 GB limit, and my time machine is only taking up 80 of the alloted 750 GB, I want to transfer some of that space across so that I'll have more room for storage.
    When attempting this on disk utility, I can reduce the size of the time machine partition, but I am unable to increase the size of the storage partition.
    Can someone please advise what I should do to sort this out without deleting the contents of each partition.
    Regards,
    Josh

    Well, this is not easily answered. You can shrink existing partitions in order to add additional ones. But in order to add space from one partition to another that can only be done by first removing the lower partition first. If that partition has data, then it will be lost. Unfortunately, Disk Utility cannot manipulate partitions in place. You need a third-party utility for that, iPartition 3.4.1.
    Now with that said I'll pass on a bit of advice. Do not us your Time Machine backup drive for extra storage. External storage and backups should be kept on separate drives. I suggest you get a separate drive for your storage or Time Machine backups.
    If you use Disk Utility you can shrink your Time Machine partition, but the only way to put that space in another partition is to first delete the storage partition, then recreate it with a larger capacity.

  • Increasing size of existing partition

    My curent Windows XP bootcamp partition is 35 Gigs using FAT. I would like to increase the size to 90 Gigs. I underdstand this requires the NTFS format. Can I increase the existing partition size without starting over? I don't want to reinstall Windows and all the Applications.
    Thanks for any help you can provide.

    Hi and welcome to Discussions,
    to my knowledge the resizing can only be done with NTFS Windows partitions not with FAT32 partitions.
    CampTune http://www.paragon-software.com/home/camptune/ would be my choice for the resizing.
    You can convert your FAT32 partition to NTFS before doing the resize using these instructions http://support.microsoft.com/?scid=kb%3Ben-us%3B307881&x=3&y=15
    For safety reasons you might backup your valuable files from your current Windows before resizing.

  • Resizing a logical partition with a LUKS container

    I have a logical partition that contains LUKS which holds an LVM2 schema.  My goal is to resize the existing logical partition so I can create other partitions in their own LUKS-encrypted container.  So far, the LVM2 PV is resized and I'm looking for advice on how to handle shrinking the LUKS container and the logical partition it lives on.
    I heard rumors that LUKS containers don't need to be resized and that I can change the size of the block device it lives on without problems.  Is this true?  If so, it seems like I should be able to delete the logical partition and replace it with a smaller one as usual.  How can I calculate the blocks/sectors/etc for the new partition with the LUKS & LVM2 data on there?

  • After resizing a disc partition using disk utilities, I can no longer boot windows. HELP! what is the best thing that I can do to fix this

    Bare with me as Im no computer genius but ... This afternoon I wanted to create more disc space on my Windows partition as I am using CAD software and wanted to free up as much space as possible. So, I went into disk utility and reduced the size of the Mac partition, then clicked apply.
    When I came to reboot the computer to use windows the windows OS, the option to use windows was no longer there.
    After looking at some online forums, I've found that most people suggest reformatting the hard drive and re-installing mac OS and also windows from back up data.
    Is there no easier way for which I will not lose any data? Please help! I really need to use Windows ASAP!

    The only apps I know of that can backup a Windows partition and or resize a windows parttition on a Mac so you don't have to go through the wipeing out, resizing and reinstall is WinClone for backing it up and WinTune (I think that is the name) for resizing a Windows partition on a Mac.
    Once you create a Windows partition, install Windows in that partition, you can't fool around with any partition on your drive with either Windows Disk Management or OS X Disk Utility and expect Windows to boot.
    The only thing you can try is to run Boot Camp Assistant.app again and remove the Windows partition and then run it again to create a larger partition and then reinstall Windows. Once you remove the windows partition put all the space back into the OS X partition and start fresh.

  • Is it possible to resize a mac partition from windows?

    Here's what's going on. I originally wanted to use Disk Utility to do this, which is clearly the easy way to do things, but my computer is so slow that Disk Utility immediately becomes unresponsive upon wanting to resize -any- partition. The windows side works fine though, it isn't slow as crap. Is there a way to resize the mac partition from windows (HFS+)? Any possible way? Even crazy ones? I'm open to suggestions.
    Oh yeah, and in case you want to know...my Mac Mini just randomly started getting really, really slow, so slow in fact, that now my old iMac from 1999 is faster (it doesn't even have ANY RAM!). I tried resetting the PRAM/NVRAM, multiple times, booting into safe mode takes forever, but I left it for awhile and it finished. Almost worked, the finder showed up quicker than usual, but then it reverted back to it's slow self again once I opened Disk Utility. I tried booting into single user mode and typing /sbin/fsck -fy, and it's so slow, that it couldn't even do that! It got stuck at checking libraries or something, for hours, and i could type things in still, but it wouldn't recognize any commands (ie fsk - fy). I also cannot replace the RAM because it is an older mac mini and those things are hard as f*** to repair, trust me, i've tried. The weirdest part of all of this has to be that this is the computer that we DON'T download many apps onto, so it most likely isn't bloatware, adware, a virus or something else. We download most stuff to our MacBook, and go to the sketchy websites on it as well (it really should be the other way around, the mac mini would be around 3x less expensive to replace, it's just that it's the family computer). And that's always slow, but this surpassed it (btw, the laptop is a year or so older). I do not have the installation disk.
    Can someone help? Mainly about the first thing...please. The second thing is hopeless, I will need to get a new computer pretty soon, and these macs don't last as long as they used to I guess, we'd most likely get a quality Windows PC to replace it, this has been a disappointment. I'm just trying to get a little more life out of it with Linux, maybe a year or two. That's what i've done with my old iMac. Runs GREAT. Especially for a 13 year old computer. The thing is, my folks don't want me to completely eliminate the mac partition even though it's virtually unusuable.

    I'm not really understanding what the end goal was. But in case anyone else comes across the thread, neither the built-in Windows volume resizing utility nor any 3rd party Windows resizing utility should be used to resize either the Windows partition or the Mac OS partition. Invariably they all manipulate the NTFS volume in such a way that the secondary GPT is corrupt, the primary GPT is rendered invalid, and only correctly alter the MBR. It's a recipe for data loss.
    Conversely, while Disk Utility can resize a Mac OS volume, it cannot resize an NTFS volume. With Lion and Mountain Lion, upon using Boot Camp Assistant there are already four partitions: EFI System, Mac OS, Recovery HD, and Windows. There is no more room for a fifth partition in the MBR partition scheme, and if you try to add one, Disk Utility will apparently let you and render Windows unbootable (because Disk Utility adds the fifth partition to the GPT, but can't add it to the MBR, and instead removes the hybrid MBR needed for Windows support and replaces it with a PMBR.)
    So in effect this is not to be done except with 3rd party utilities.

  • I was trying to resize my bootcamp partition and it got deleted now I have 217 GB of free space that I cant use and I want to rejoin it with my macbook partiton.

    So I was trying to resize my bootcamp partition with Paragon and it was taking forever so I decided to use iPartition the Paragon started doing something and it was almost done when my macbook began to shut down. It was shutting down becuase I though the paragon wouldnt work. Anyway it shut down and I wasnt able to boot to the iPartition CD, so I decided to just screw it and just stick with Mac osx. Then while in the iPartition app once I booted up back into OSX it said I had 217 gigs of free space and my hardrive/mac os partition can only use like 270 gigs. But I desparetely need these 215 gigs back becuase I do things that require alot of memory. Does anybody have any idea how I can rejoin this free space with my mac partition. I already tried it in disk utility and it kept failing with a couldnt unmount disk error everytime I tried to resize back to its full size! PLEASE HELP! Heres a pic of what iPartiton shows me.

    You need an external disk that is formated as HFS+ with a GUID partition map.
    You can use either Carbon Copy Cloner or SuperDuper to create the clone.
    Once ypu have the clone you can boot from my holding down the option key ater power on.
    Once booted from the clone open Disk Utility.
    Select the internal drive.
    Click partition.
    Select single partition.
    Once drive has bee formated, restore the clone nack with the application used to make the original clone.
    Boot from internal drive.

  • Why can't you encrypt an existing partition?

    I've looked around for a tool like ccrypt for partitions but to no avail. In fact I came across a thread on this forum that simply stated it wasn't possible. Why can't you encrypt existing partitions? Or is there a way to do it?

    You should look at TrueCrypt. You can use encrypted containers where are essentially encrypted partitions that can also be hidden. TrueCrypt supports on-the-fly disk encryption, this may be what you are looking for.

  • Dynamic resize of FAT32 partition with disk utility?

    Hi there.
    I have a 1TB external FAT32 drive with 300GB of data on it.
    I want to convert it to HFS+, but I know there's no easy way to do that.
    What I want to know is can I resize my FAT32 partition to 500MB and keep all the data?
    Then I'll move it to the new HFS+ 500MB partition, delete the original partition and resize the HFS+ partition.
    Or do I have no hope of that?
    Thanks
    Greg

    Greg,
    You're probably out of luck on this one. If the drive was partitioned and formatted by a PC (every drive has a partition map, whether there are multiple partitions or only one), it almost certainly has an "MBR" partition map. This would preclude a dynamic resizing by Disk Utility. It will need to be partitioned using either GUID (Intel) or APM (PPC).

  • Problems Resizing "Macintosh HD" Partition

    I recently bought a macbook with Leopard installed on it. I wanted to install XP on it, and with bootcamp, created a 32GB partition. (I had 232GB of internal hard drive space altogether) After concluding the first XP install stage (blue screens with partitions and creating files) there was a mishap. I decided to merely delete the second 32GB partition and resize my original. While I was able to delete the second one (BOOTCAMP), I was not able to resize my original. I tried to resize it from Disk Utility. I used the First Aid option to try to repair it, but it did not allow me. When I verified the permissions and disks there were errors. My question is, how can I resize my primary partition (currently 200GB and labeled Macintosh HD) to be 232GB?
    Thank you.

    IIRC you can't resize an active partition - that is, the partition you're currently booted from.
    You'll need to boot from some other device - either an external hard drive, or the Leopard Installer DVD in order to resize the partition.

    Hello tw
    Like I said in my explanation If you want to install OS on a partition please use Expert mode. In this case the software can be installed onto an existing partition. You can also make one by yourself.
    If you want to install the OS on existing partition make it on this way:
    1) put Recovery CD or DVD in DVD drive
    2) pres power button and after that press and hold down C button
    3) after short time there is an menu and choose Expert mode pressing number 2
    4) Approve OK pressing ENTER button
    5) Choose LOCAL > PARTITION > FROM IMAGE
    6) Look in: must be selected to CD-ROM drive and In the middle window choose GHO file and press ENTER
    7) The information about drive will be shown > press ENTER again
    8) The local destination drive will be shown > press ENTER again
    9) The next window show both partition if you have two of them. On this place you must chose the destination partition (the first one is under Part 1)
    10) The OS will be installed on marked partition (you can change it using UP and DOWN buttons)
    11) If the partition is selected press ENTER button
    12) The small Information window appear with follow content: Proceed with partition load? Destination partition will be permanently overwritten.
    13) Confirm with OK
    I hope that your installation will be successful.
    If you have more questions please write again and I hope that we will find an solution.
    Good luck!
