Cannot resize partitions on yosemite !!

cannot resize partitions on yosemite !!

Do they have data on them? Are these partitions you could resize before? Is this a new machine? Is it formatted GPT or something else? Are you using boot camp?
It would be helpful, also, if you would phrase your question in the form of a question

Cannot resize partition...

Before mods delete/close/move my post 'cause I'm sure there exist hundred of related problems to this let me explain.
I study Engineering in Computational Systems, for my Digital Design class I need some software that only exist for Windows (I've been searching the web looking for alternatives for Mac without success)... So I decided I'd install BootCamp and Windows 7, but I got the **** "cannot resize partition" error...
So here's the deal... I CAN'T make a backup, my external hard drive is damaged, I've been searching and I found that this problem is 'cause BootCamp can't move big files or stuff like that so to fix the problem I have to defrag the hard disk and here comes another problem, I can't afford iDefrag neither...
Any help for defrag or resize my Mac OS X partition?

Usually when I see "Cannot resize..." it is because the Windows partition was too small, or they need more room for OS X files. Not because they got the error message from Boot Camp Assistant (which tells you to reformat and restore after you have a backup).
Step #1 is (always) backup before making changes.
Real easy... buy an external, you will need backups for Mac OS and probably Windows. you will want to be able to run OS X off external too at some point.
It isn't because there are big files, it is that they can't be moved.
The free space has to be contiguous, not fragmented, also, in order to create a slice for Windows.
I assume it won't work with a VM running under/inside OS X so you need to run Windows natively.
Some people have bought iDefrag ($49?) and results are anywhere from good to mixed to didn't work.
You are right, the question has been asked... about 999 times in the last two years.

Cannot resize partitions

Hi.
I have an external usb hard drive. And it has been partitioned previously into 2 partitions. Approx. 500 GB each.
I open DU, choose my HD and go to Partition tab. Then it says:"To resize the volumes on the selected disk, drag the dividers between them and click Apply".
For some reason there is no divider between my partitions.
I have no way to copy all my info somewhere else. When I click and drag that little corners it doesn't work out.
All I want to do is to increase the size of the TM backups up to 800GB and decrease the size of the Server down to 200GB.
Any suggestions ?

I think you misunderstood the instructions. Grab the sizing gadget in the lower right corner of the Server volume and slide upwards until you have reduced its size by the amount you want to add to the TM volume. Click on the Apply button and wait until the process finishes. Then select the TM volume by clicking anywhere inside its rectangle and click on the Delete [-] button to remove it. Then click on the Add[+] button to add a new partition in the free space. Click on the Apply button and wait until the process finishes. You should now have a resized volume for your TM backup. Be aware that this process will remove your existing backup, so you will need to reconfigure TM and start a whole new backup.

Can't resize partition after upgrading to Yosemite (using SSD drive)

I upgraded to 10.10 and using SSD drive now. When I was using OS X 10.8.5, I could freely resize partition but not anymore. I guess because of the SSD drive and the new version of OS X, and Logical Volume Group could be involved. I don't want to waste 80 GB of SSD drive so really looking for a solution now. Thanks in advance.

Yes, that's exactly what I did. I had to go back to my old snow leopard install DVD, use the disk utility on that to repartition the drive. I made 2 partitions, installed Snow Leopard on one, used that to install Yosemite on the other partition and trashed the snow leopard install.
I haven't yet tried the Yosemite USB install method which would have probably been faster as I could have avoided installing SL.

Yosemite, Boot Camp, Windows 8.1 - Resizing Partition Guide

Hey everyone, I had some success with this so I thought I would share:
What you Need:
0) familiarity with the command line, HD partitioning, linux, and lots of nerve.
1) Yosemite
2) A successful installation of Windows via Boot Camp (I was using 8.1 and I did the installation after I upgraded to Yosemite, i.e., I did not have a Boot Camp partition before upgrading to Yosemite) <-- Any other type of config may not work with this guide!!
3) A Linux live usb/cd with gparted (I assume you're familiar with linux and gparted and things like that, I'm not going to go into too many details on how to use that OS or its tools)
4) patience and luck
Disclaimer: This can really screw up your system if you fail to follow the directions or you have made the storage gods angry... use at your own risk!
So initially I created a boot camp partition to install Windows 8.1 and after the installation realized I should have allocated more space for Windows. On the OS X side, I opened the graphical diskutil and discovered I could not resize or change either of the partitions - the only thing I could do was delete the boot camp partition which was not a handy option considering the time I put into installing Windows and its subsequent updates.
After some careful googling I found this:
http://apple.stackexchange.com/questions/134498/unable-to-resize-partitions
Which led me to the solution. From a terminal run: 'diskutil corestorage list' (without the quotes) to get a list of the logical volumes, groups, and physical disks that OS X created after using boot camp. The information you will need is the UUID of the logical volume (not the logical volume group or family). You are then going to use the undocumented command 'diskutil corestorage resizeStack' with the UUID of the logical volume in order to change the size of the volumes and physical disk. In my case, I wanted to shrink my remaining OS X partition by 40GB and give that to Windows. Again from the terminal run:
'diskutil corestorage resizeStack UUID XXXg' where UUID is the 32 digit identifier of the logical volume and XXX is the desired new size of the disk (e.g., 350g for 350 GB).
After a few moments, it will finish and in diskutil you should see an amount of unallocated space. You still can't do anything with it here, but at least it's visible. Reboot into OS X again just to feel confident that you haven't screwed anything up, yet. It did seem to take slightly longer to reboot into OS X this one time, but everything turned out ok
Now using a linux live usb drive, boot into your favorite brand of linux and run gparted. You should see your unallocated space sandwiched between your OS X partition (which gparted may or may not formally 'see') and the NTFS Windows partition. Simply move the Windows partition over to occupy the unallocated space and extend it to the end of drive and you're done. My version of gparted warned me that Windows may not boot after I do this, but for me, it worked fine and booted into Windows properly the first time. If Windows doesn't boot, you'll need a Windows install on a usb stick (you should have one from your boot camp installation right?) and then you'll need to repair the disk (there are many helpful guides that go through this very thing - just google it).
It worked for me flawlessly, good luck!

Everything has worked so far, I have freed up about 75GB that is in between OSX and my 8.1 Bootcamp Partition, however I can't for the life of me seem to make a working Linux USB. How can you make a BOOTABLE (from this retina macbook pro) Live CD with Gparted. What tools/ISO did you use?

Cannot resize system partition due to recovery partition

Hello.
I have a 500GB HD (momentus XT) that replaced my default 320GB HD.
i cannot resize the system partition due to the recovery partition. System keeps on telling me that "map is too small".
Tried diskutil under osx, under lion bootable recovery usb stick, under diskutil through console.
Here is what diskutil tells me.

Resizing
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? ;-)

Bootcamp Yosemite 10.10.1 "The startup disk cannot be partitioned or restored to a single partition."

I'm trying to install Windows on my Mac via Bootcamp. I start up Boot Camp Assistant, the introduction pops up, I press continue and then I get this error message.
"The startup disk cannot be partitioned or restored to a single partition.
The startup disk must be formatted as a single Mac OS Extended (Journaled) volume or already partitioned by Boot Camp Assistant for installing Windows."
So I head over to Disk Utility, the only partitions I have are Macintosh HD and EFI. I thought there might be some hidden partition, so I went into debug mode in Disk Util and there's nothing (Also used terminal, I'll put results below*). So that brings me to my current problem; it's already "formatted as a single Mac OS Extended (Journaled) volume" and I can't make it "partitioned by Boot Camp Assistant for installing Windows." because this error message prevents me from doing that. Maybe there's an easy fix, but the information provided is so unhelpful/circular it makes me want to laugh and punch something at the same time. I saw that someone fixed this problem by merging their partitions, but as I already have the minimum number of partitions so that wouldn't fix anything (unless EFI is unnecessary, which I'm fairly sure it isn't).

Thanks for your help in advance ;3, I hope this is an easy fix

I had a similar issue after doing a fresh install of Yosemite. Bootcamp assistant seems to want a Core Storage scenario before it will continue.
To convert your drive use the following command in Terminal:
diskutil cs convert disk0s2
Bootcamp will then let you proceed as normal. Be warned though!
After the windows install completes you may end up with something like my situation:

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?

Cannot resize the partition C

Hi,
I have a problem with resizing my partition C on Windows 8.1. It only has 28 GB and I have run out of every space. The Disc manager for resizing partitions is not working (every option for a Disc C is greyed out). I downloaded three partition managers: Paragon,
Aomei and one more (don't remember the name, cause I deleted it already). All of them were supported by Windows 8.1 32 bit. And still it was not possible to do anything with the disk C, even though I have a lot of unallocated space to use.
I also deleted disk D, so that only Disk C was left, and still I couldn't allocate any space to it, only to shrink it.
Can anyone tell me what else can I do?
It is driving me crazy already. Help please.
Marta

Hello,
I used aomei partition assistant before in my windows 8.1, it worked well. do you use "resize partition" in aomei partition assistant to extend you c drive? if you do like this, the unallocated space on your hard disk should be contiguous behind
the partition c, or you can't extend partition. but if the unallocated space is not contigous behind partition c, you an use extend partition wizard or merge partitions to extend partitionc
extend partition wizard: http://www.disk-partition.com/windows-8/change-partition-size-windows-8.html
merge partitions: http://www.disk-partition.com/help/merge-partition.html
hope can help you

Can't resize partitions anymore

Firstly, thank you so much for the tips Loner T. I decided to take the plunge and upgraded to Yosemite. Like everyone else, after the upgrade, my Windows didn't work anymore. I followed your instructions in other threads and am able to boot into Windows again.
The problem I have now is that I cannot resize the Mac or Bootcamp partitions. I was able to do this before the upgrade to Yosemite.
I suspect it may be because I have unallocated space sandwiched between my recovery and bootcamp partitions. Is that true?
Here's how gpt looks like:
Here's how disk utility looks like:
Also, I noticed I have some disk space left at the end of the bootcamp partition as well. Can I just use gdisk to specify the end of my bootcamp partition to be 977105026?
Thanks

You can stretch the partition, but it can cause potential problems later. There are backup blocks stored in specific locations, including MFTs. If the primary such blocks are corrupted, recovery will use back up blocks. For example chkdsk uses this technique, among others. If you move the end marker of the partition, you also need to ensure that the the OS recognizes it properly. If you really want to do this correctly, my suggestion would be to use GParted or similar tools found on Linux Live CDs.
The 1936 sector offset is 968KB which is the boundary alignment offset, the other (716938 sectors) is 350MB. The return on investment is not commensurate with the effort involved, but it is a good learning tool.

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).

Resize-partition PowerShell - using a variable for size

Hello.
I'm trying to user the PowerShell command resize-partition as part of a RunBook task so I need to be able to specify the size as a variable. The -size element requires that you also add on the size type (e.g. kb, mb, gb, tb etc.) but this makes the command
fail as its then passed as a string and it looks like it wants to be a UInt64.
I have tried various different ways such as:
$size = 300 + "gb"
$size = "300" + "gb" etc.
The error I get is:
PS C:\Windows\system32> Resize-Partition -DriveLetter E -Size $Size
Resize-Partition : Cannot process argument transformation on parameter 'Size'. Cannot convert value "300GB" to
type "System.UInt64". Error: "Input string was not in a correct format."
The only way I can get it working is to hardcode it in: '-size (300gb)'
Would anyone have any idea how to get this working? It must be possible.
Thanks, Joe

Bootcamp - The disk cannot be partitioned because some files cannot be moved.

I know what you're thinking; this question has been posed before. But my circumstances are different.
Sooo I bought a brand new Macbook Pro 15" Retina, late-2014 model on Monday. After some initial setup (moving my music, downloading programs etc.) I moved onto the last thing I needed to do - set up bootcamp (primarily for gaming I admit).
Specs: 2.8GHz Quad-core Intel Core i7, Turbo Boost up to 4.0GHz
16GB 1600MHz DDR3L SDRAM
1TB PCIe-based Flash Storage - In total the files I moved onto it left me with about 890GB free on the HD.
At this point I had made sure everything was updated as far as I was aware.
I received the error message "The disk cannot be partitioned because some files cannot be moved." I was trying to make a 151GB partition but also tried going down to 40GB and received the same message. I tried several solutions I found online including booting in cmd+s and typing in some codes, I checked the disk with disk utility and it was fine.
Nothing much for it and I was feeling lazy, I backed up with Carbon Copy Cloner (I much prefer this program to time machine) and reformatted. Clean install of OSX Yosemite and the Macbook looked like it had just come out of the box. Before I even attempted to restore using CCC I started up bootcamp again: same error. With essentially a brand new Macbook Pro right out of the box, near to 1TB HD space free.
I've taken it to the local Apple store but they "Don't have any support for bootcamp in-store" and I'm out of the house for 12 hours a day with work (I'm actually at work now). Plus you know, I require food and such, so I don't get much time to get in touch with Apple support directly.
The guy at the Apple store recommended Parallels or Visualbox; note that I want to use bootcamp. I like the extra power and I have a copy of Windows 8.1 from a previous Macbook Pro that worked wonderfully through bootcamp. This should work as far as I am concerned and I don't want to accept anything less to be honest.
Any ideas?

Hi Loner T,
Thanks for your suggestion, however I did a step wrong and I am facing another bigger problem.
Step 1 was to use time machine to backup OSX, looks like I failed to do that, and only backed up the data instead. Because after I erase my internal disk, I cant restore from TM.
So now the situation is that I can't access my HD, can't reinstall Mac to that hard disk (it is not detected), Cant use DU to repartition the hard disk as well, option not selectable.
What can I do now?

Cannot increase partition size

I originally had three two partitions one called BOOT and one called FILES. I ran out of room on my boot drive and I was told to clone it, add a partition with a larger size and clone it back to the larger parttion. I crteated BOOT 2 and then once cloned back I deleted BOOT.
Now I cannot increase the size of FILES to its original size and cannot seem to recover any of the space from the original BOOT parttiion. Neither BOOT 2 or FILES can be increased. How do I acheive this?
Here is a screen capture of what is going on.......

You can not do that with Disk Utility. While it can be used to create and resize partitions, it can not be used to regain the space between partitions if there is data on the second partition.
You might try something like > iPartition for Mac - Smart hard disk partitioning utility.
But personally if I were in that boat. I would Clone the data from the 2nd and 3rd Partitions to partitions on an external drive. Then start over by reformatting the internal drive into 1 or 2 new partitions using Disk Utility and then clone the partitions back onto the internal drive.
In addition: In OS X it is not necessary to have a boot partition and a file partition, OS X does quite well at managing everything including quite large user libraries in one partition.

Resizing partition

When I added arch to my system dual booting with Windows 8 I only gave it a total of 32GB, but now I would like to have more space. Is it okay to use Window's partition tool to expand the partitions, or will Arch freak out that the partition is bigger than it expected?

@Arctus, I think that you are thinking of this as a single thing. But there are actually a couple distinct things going on here. There is the partition itself, which is the container. Within that, there is the filesystem that actually is the structure that holds the data. So while I agree with you that you cannot resize Linux filesystems with windows, it could most certainly deal with the ms-dos partition table (MBR) no problem. Also, no one in their right mind would try to use FAT or NTFS for a Linux filesystem. They are both not POSIX compliant, and the necessary permissions would not be retained, which would likely prevent the computer from really running at all (not to mention NTFS-3g is a fuse filesystem, and I'm really not sure about using that for a rootfs).
@OP, Typically, in my head, and in other places I have read, the first partition is though of as being to the left, and the last to the right (like how you would read a line of text). So assuming this notion of HDD layout, you could shrink your windows partition, then boot into a live linux distribution and use gparted to move sda3 to the left. But this is what I was saying was dangerous above. It can be done, but there are great risks to your data involved. So if you do this, you should back up your data first.
But if you are going to back up your data first, then you could simply rsync the entire system to a backup HDD. Then simply delete all sda{3,4,5,6}. Shrink the windows partition and then create the layout you want with new partitions. Go back into Linux, make the filesystems and mount them after creating the necessary mountpoints for them (as though you were doing a new installation). Then simply rsync the data back to this new filesystem.
A third option would be to actually create a new rootfs in the new space taken from windows. So you would make a new partition all the way to the "left" and then simply rsync or dd the current sda3 to this new space. You would then keep moving all the partitions over to the "left" and then extend what you needed to. The only problem with this is that since you use ms-dos (MBR) partitioning, you are going to probably not be able to create more partitions since you already have 4 primary (well 3 primary and one extended).
I would use the rsync method. I have used it many times in the past and it is very reliable. The neat thing about Linux (*nix in general) is that everything is a file. So you can actually just move all the files to a new location, and you *should* have a copy of the original.
