OS X Mavericks :: Disk Utility Crashed Whilst Creating Partition And Now Missing Hard Drive Space
Jun 3, 2014
Disk Utility Crashed whilst creating a Partition, and I now have ~100GB missing, which was the amount I had allocated to the new partition.
The new partition didn't get created, and I now have 100GB missing from the Hard drive. I have a 1TB hard drive, and when I go to Disk Utility, it says: Â Capacity : 999.35 GB (999,345,127,424 Bytes)Available : 586.1 GB (586,103,844,864 Bytes)Used : 310.52 GB (310,524,317,696 Bytes)Â
Which adds up to about ~900GB.
I tried Repairing Disk in Disk Utility, booting into Recovery Mode and Repairing Disk there, but neither made a difference.Â

I'm getting ready to sell my old Powerbook G4 so booted up from the installation CD, and ran Disk Utility to do a 8 Way Random Write pass on the Mac hard drive before I did a clean install (the disc is Mac OS X 10.3.7).
I selected the top option in the drive panel of Disk Utility (the one saying 92.2GB Hitatchi blablabla) rather than the indented disk beneath it.
All went fine doing the overwrite, however it seems to have become stuck on "Creating Partition Map" - it's been like that for half a day now. Any thoughts? Should I have chosen the indented drive underneath the main description?

I have a 2TB Western Digital My Book Studio FW800 external that has 5 partitions, connected to my 2011 iMac. I had help doing the partitions and don't really remember the reasoning, but one is just for my SuperDuper! backup, one is Miscellaneous, one for movie clips off my camcorder, one for misc scanned photo's and one for my genealogy research. I back up using Time Machine to a Time Capsule and also to this WD hard drive with SuperDuper!Â
Recently I'm getting a pop up message that "Mac OS X can't repair the disk "Genealogy"'. And it needs to be reformatted. It's become a read only disk. When I look in Disk Utility it shows all the partitions as "Mac OS Extended (Journaled)" EXCEPT for the one in question. I also noticed that there are a lot of files with "date created" being the same date in 1969! These files may be letters I've written or photo's I added to that partition within the last few years.Â
I think I have to completely reformat the entire external hard drive to repair this, but I want to make sure. Because it's going to be a major hassle backing it all up to another external (having to get one first) and then figuring out how to make the files that have turned "read only" in that one partition, back to their original state!  Does this sound right, that I have to reformat the entire external hard drive? And how do I get the read-only files back to their original state.

My 500gb iMac (purchased April 2010) is about at capacity. 350gb of space is taken up by home movies (.mov) in iMovie. I bought an external hard drive and have moved about 200gb over to that drive.Â
After transfer, I deleted the original Events off iMovie and emptied the trash. I checked in both iMovie and in Finder and no longer see those files present on the Mac. Â
I thought this was going smooth and everything worked perfectly, but….when i went to check how much storage space i created on the Mac, the amount of available space barely budged (i moved 200gb of data to the new drive and i created about 30gb of space on the Mac).Â
Are these "deleted" files hidden somewhere and I need to go delete from somewhere else? How do I make sure I get back the storage that i need?Â

I wish to change partition scheme, sizes, in an external drive. All the partitions are MacOS extended (Journaled) and they map, according to the layout in Disk Utility, as follows: Partion 1, 2, 3,4 where 1 is at the top and 4, the bottom. I want to make partition 2 larger, so I decreased partition 1 by half. Now the layout is 1 a, 1b, 2,3,4., where 1b is now free space. Disk Utility will not allow me to increase the size of partition 2 by dragging the corner. Which of the following options (if any) will allow me to increase the size of partition 2, without erasing the data, using Disk Utility:Select partition 2 and manually writing a new value in the size box, equal to the present partition’s size plus the free space?If I delete partition 1 completely, will I then be able to increase the size of partition 2?If I delete partitions 1, 3, and 4, will I then be allowed to increase the size of partion 2?Is there another option?
(Actually, partition 3 is an eDrive, a data recovery utility created by TechTool Pro 7, so I don’t really know how it’s formatted.)

I was making a partition on my USB external drive in order to put a disk image of Snow Leopard on it, so I could boot off of it.
I added a 10GB partition to the drive, and clicked Apply. The following dialogue box came up:
Partitioning this disk will change some of the volumes. No volumes will be erased.
This volume will be added:
"Snow Leopard"
This volume will be resized:
"XXX HDD"
I clicked Partition, and it finished very quickly. I checked Finder, and the entire drive, BOTH partitions are completely empty.

i am trying to format a brand new 120 GB hard drive via an external USB 2.0 enclosure. About 25 minutes ago, I selected the "erase" option and slected the Mac OS Extended (Journal) Volume format. For the last 25 minutes, disk utility has been saying that it's creating a partition map. It's doing nothing.
I have reason to believe my enclosure may be faulty. (I had a similar problem on an old hard disk and thought that the problem was with the disk; now I know.) I need to know: How do I disconnect/eject the hard disk without damaging it? The eject option in Disk Utility is grayed out. If I attempt to quit Disk Utility I get a warning telling me I could leave my disk inoperable.

I've been running a Toshiba 1TB external drive on my Mac Pro tower and it's been working fine. But yesterday it wouldn't mount. I could see the drive in Disc Utility, but the partition wouldn't mount. I brought it into work where I'm running an iMac and it mounted just fine. Why would it stop working on one computer (where it was previously fine) yet work okay on another? And how do I get it working on the tower?

I have an external 750GB hard drive that I previously formatted as FAT 32 because I wanted to be able to plug it into Windows computers as well. I was not very thoughtful at the beginning and I just created one big 750GB partition. I currently have 450GB used and about 300GB free.
I would like to create a new partition in the free space without losing the data I have in the disk, and format the new partition as Mac OS Extended to use it for Time Machine backups. Presumably Disk Utility can do it, but when I go to the "Partition" tab it says "This partition cannot be modified" and the "+" sign below it is grayed.

The hard drive is a 1TB Western Digital my book I bought it in January I think. I tried to format it to Mac OS Extended (Journaled) when I got it but for some reason every time I try to erase the part thats named disk3s2 or partition the main one it stops a little before half way through. I don't think its the hard drives fault so I called apple about it one day and they helped a little but it didn't work. Thanks in advance if you can help me. Also a few times I waited about seven hours for it while I was at school and when I came home it didn't move.

I have a 1/3 full external drive that is currently formatted for MAC OS External.
I want to partition the drive in half and use the 2nd partition for Windows FAT32.
However, when I try to do this with Disk Utility it does not give me the FAT32 option.

I recently tried installing Ubuntu on my MBP. After never really using it, I deleted it and removed all the partitions. My problem is that there is still some 'empty space' (about 5 GB worth) that I cannot re-add to the main HD's partition. The space is not a partition of it's own, I can resize the partition box down to it in Disk Utility, but I get an error.
The error message is...
Partition Failed
Partition failed with the error:
Mediakit reports the partition (map) to small.
While it's not a big issue (314 out of 319 GB)

Can anyone explain to me why, on my iMac's 500GB hard drive, the displayed size of the only 4 items on it is 207GB, that the info box on the HD itself says 393GB used? Unless I failed grade 1 math, 500GB - 207GB = 293GB, right? So where's the missing ~100GB? That's a lot of space I know I haven't filled up.Â

I tried yesterday to make a Boot Camp partition on my MacBook Pro 17"s 500GB hard drive, but something seems to have gone wrong while installing Windows 7. And the new partition was inaccessible from Disk Utility, so I deleted it by booting from the Windows 7 disk. But now the unallocated space from the deleted partition isn't showing up in disk utility, and I have now idea how to remerge it with my main Snow Leopard partition.

I have a new iMac using OS 10.9.4. I got an external HD for backup purposes and successfully formatted it. Now I want to create partitions; however, my Disk Utilities app does not contain any tab or command for creating partitions. Where should I be looking?Â

Model - Macbook Pro 2013 Retina
Issue - In the disk utility, the free space under partition and Macintosh HD do not reflect on each other. There is the difference of about 10GB between these two.

My hard drive crashed and corrupted some of my iMovie MOVs. When launching iMovie, I get a series of alerts (attached image). I'm trying to find what is making iMovie look for these files so I can clear out the reference. I tried searching for the file name and nothing comes up. I already know the file is missing, I'd just like iMove to stop looking for it.

I just used Disk Utility to make a backup of a MBA (65GB) onto a 500GB external drive (Restore from internal HDD to external HDD). I then reformatted the internal hard disk and proceeded to restore my backup (external HDD to internal HDD). I soon received an error message stating "Restore Failure - not enough space". I guess that means Disk Utility backups are a one-way operation, since you can't restore from a larger drive to a smaller one? Is there something I am overlooking? I ended up using Carbon Copy Cloner to do the job, but I'm wondering how (if?) restoring from a larger backup drive is possible using Disk Utility?

I'm running out of hard disk space on my MacBook pro running OS X Lion. I have a 500 GB hard drive and at the moment the finder says I only have 16 GB available. Checking the total of all my files with the finder as well as Apps such as WhatSize and Disk Inventory X only adds up to aproximately 420 GB of files. Therefore I should have about 80 GB free so I am missing 64 GB of hard disk space.
The problem is not the local backup storage as I have had this problem before and have turned off local backups. I have also run disk utility and shut down and re-started. The available disk space is not decreasing with time either like other people have experienced, its fixed at the current availabilty of 16 GB free, and adjust normally as I add and remove files. So there really is a hidden file or something that is using around 64 GB of space.
I noted that a previous post with a similar problem said that DiskTools pro had fixed the problem. However as this application is reltively expensive and there is no explanation of how it soved the problem I don't want to pay for it without some guarantee of results.

I have a 3 TB disk that I used for video files that I now want to use for backup. So I wanted to erase and partition the drive to wipe it clean. So after going into Disk Utility and "trying" to erase and partition the drive, it now only shows the drive and no volumes.I cannot create or partition volumes. I tried verifying and repairing the disc but that didn't do anything. The only buttons available are Verify, Info and Burn. What do I do to use the drive again?

Did a fresh Bootcamp install of Windows 7 on my MBA running 10.9.4, switched back and forth a few times and now the BOOTCAMP partition doesn't show up in the left pane in Finder. I hopped into Disk Utility to see what was going on and it was there, just not mounted, so I clicked mount, was told it couldn't be mounted, and it suggested I run first aid on it. I clicked Verify, nothing useful to me, then Repair, and got quite a lot of feedback that I do not understand, and then after that it was still unmountable.Â
I tried to copy everything it said into a pastebin because it was very long with lots of starting and stopping and counting percents inbetween, but it was over 500kb and that's the limit for free users on pastebin, so here's a trimmed version. [URL] .... I tried booting into Windows after that, and it jumped into System Repair. Apparently, according to Windows, my Boot Manager is missing or corrupt... and since I still can't access it from the Mac side of things, I thought I'd just wipe the partition in BootCamp Utility and start over.
Except instead, I get this error: "Your disk could not be restored to a single partition.An error occurred while restoring the disk to a single partition."Â
Disk Utility let me wipe it but I still can't mount it, either, again suggesting I run first aid on it (this does nothing). I can't boot into the Mac's Recovery mode either. It just jumps straight to Internet Recovery. When I hold option upon boot, all three partitions show up (Mac, Recovery, Windows), but when I click the recovery one it loads for a bit and then the laptop just instantly shuts off.... Have I corrupted my internal harddrive perchance?

I've been backing up my Powerbook G4 for a few months using Time Machine to an external firewire drive with two partitions; one for the backups, and a much larger one for all my music, video, pictures, etc. I got a new mac mini over the weekend and I want to format the Time Machine partition without erasing the one with all my other files so I can start backing up the Mini.
Is this possible using Disk Utility? If so, how?
Both computers are running Leopard.

I'm having a pretty serious problem. I attempted to erase the free space on my HD, as I do from time to time, except this time it appeared to hang/freeze at the end, when it gets to the part where it creates a temporary file. I waited for several minutes and it didn't move. I tried clicking the skip button, but that did nothing either, so I force quit Disk Utility.
The problem is, it left the disk at "Zero KB" of free space, effectively making my computer inoperable. I was in the process of studying for a huge exam tomorrow, and am currently flipping out.
If it matters, I'm on a Macbook Pro 2.33 GHz Core 2 Duo, running 10.4.
I really don't want to have to reinstall the OS and import the old files, but my real fear is that I will have to do a fresh install of the OS.

Trying to resize and existing volume using disk utility on Leopard. Have a 1TB internal Drive with 1 Partition (extended Journal), not a boot drive this is just for data, now want to add another partition (2 Volumes), in effect shrinking the size of the original so I have 2 equal sizes.
So Far I have used 450GB, so there should be enough room to do this right? Although when I go through the process, I get the message 'not enough space on drive'.

Fortunately I got a time machine backup. And its restoring the drive while in Lion recovery mode. Here's what happened... I dont have a router a my place at the moment and so my two phones (iphone 4 and htc android) connect to my internet using my MBP's wifi via internet sharig. For some reason they were not able to get an IP from the mbp. After doing some wifi swtich toggles and forgettig & rejoining the network, i decided to reboot all my devices. I shut down my modem, phones and restarted my mbp. On reboot, after the chime, it showed an unsusal 'progress bar' under the apple logo. The bar progressed to about 10% and then the mbp just powered off. This happened several times even after PRAM and SMC reset. Â
So now i booted with cmd+r pressed and in recovery mode ran a 'verify disk'. It said the verification stopped and that i should repair the disk. When i tried to do that it said the disk cannot be repaird and that i should back up as many files as possible and attempt to format the disk and restore it with time machine. It is precisely what im doing at the moment. Â
1. Mbp wont sleep even when internet sharing is off
2. Mbp wont lit the onboard display upon opening it in clamshell mode until i removed the 3.5mm audio cable of my speakers from the audio out port!Â

I've done some searching on the forums, but I cannot find exactly what I need. I currently have a Maxtor external hard drive partitioned into two sections; one for time machine, the other for music, movies, etc. Normally, the two separate partitions would show up on my desktop (labeled "Music" and "Time Machine") but as of lately the Time Machine partition fails to show. I cannot find the volume anywhere, but the Music partition still reads perfectly fine. how I can relocated the Time Machine partition?

I have a mid 2011 21.5" 2.7 GHZ I5 IMac with a 1 TB HDD. It is reporting that the startup disk is full (<8gb left). I have surveyed the hard drive and found the "users" folder is using 972GB.The sole "user" folder (me) is using 972 GB An exploration and sum of "folder size" of each of the underlying folders (there are 8: Audio books, Desktop, Documents, Download, Movies, Music, Picture and Public) collectively sums to 316,6GB. The system tool in "about the iMac" (storage tab) shows "other" allocated a 893,97GB. Where is the missing 640GB plus of space? Please can anyone advise me how to identify where space has been allocated and how to rectify the problem? Â
I have done the following: All updates are installedVerified the partition - no faultsTimemachine - never been activatedre-indexed spotlight as suggested in a support article.deleted a dormant user (6GB) and deleted their dataI have emptied the trash. What else can i do?
