IMac Disk utility volume doesn't go away?

Hello! Could anyone please help me with this? (Please bear with me since this is my first post)
So a couple of days ago I tried to bootcamp my mac to install windows 7 while half way through the power went out...
It came back on to horror as when I booted up the Mac I had over 300GB of hard drive space eaten up and gone.
I spent the next few days fooling around with help related topics Ive found on the forum to try and get that space back.
But eventually I decided to just reinstall the OS since i messed up so badly, wasnt a problem for me since I back up everything.
Eventually I was able to clear a space for "internet recovery" mode to re-dowload mountain lion and install it.
But when I logged in and set everything up I was greeted with 2 Macintosh HD's
In disk utility it looks like this, which greatly confuses me:
How could I get this to be all one partiton again? To be able to install windows 7 on boot camp it says it needs to have the whole hard drive as one partition.
So Ive been stumped all day as to how to get it back together, Ive tried third party software, booting from a live USB and editing it, and still nothing has been able to change it.
The first Macintosh HD is around 700GB and the 2nd one is around 300GB but its a fusion drive (I think the SSD is 128GB hooked up to a 1TB HDD because it shows up as a 1.12TB drive)
I can read and write to both areas as they show up in finder as if they were hard drives.
But I get no option to shrink or expand them or combine them back together...
Technical Information:
iMac 27-inch late 2012
1TB Fusion Drive
OS X 10.8.4, Everything up to date
Thank you very much for your time in reading this and I hope you can help me, or well I hope someone knows how to fix this!

Welcome to Apple Support Communities
It looks like Fusion Drive messed up everything. In this case, I recommend you to make a backup of your data and format the whole Fusion Drive.
First, get an external drive and make a backup of your files with Time Machine > http://support.apple.com/kb/HT1427
When you have done that, hold Command, Option (Alt) and R keys while your Mac is starting to start up in Internet Recovery (not Recovery HD), so you can format the whole Fusion Drive. Open Disk Utility and follow these steps to format it > http://pondini.org/OSX/DU1.html
Finally, check that everything is OK in Disk Utility, close it, select the option to restore a Time Machine backup and follow the steps. Another thing you can try is to reinstall OS X as usual and restore the backup during the setup, which is safer

p.s i have no experience in apple imac's at all never used before, but im kinda windows nerd so computers i understand but this imac make my insane, cant seem to find any solutions anywhere on the WWW....

Your HD may be crashed, so you probably should use the oringinal install discs to run Apple Hardware Test in extended mode. If error codes appear this confirms a hardware failure. In addition you cannnot repair the HD using Disk Utility from the startup disk, you have to use the origninal Install discs that shipped with the computer or the most up-to-date version of OS X on a disc that you have.

My Disk Utility window doesn't look anything like the one in the Help file

My Disk Utility window doesn't look anything like the one in the Help file. It is missing the top row of icons (Burn etc.) What happened?

Nevermind - I found the "Show Toolbar" Command.

2nd Hand iMac wont boot. Tried "repairing drive" in recoveryHD disk utility but doesn't fully pass through. HELP! :(

I have just purchased a second hand mac from Gumtree as Im eager to get into the beauty that is OS X.
But when I try and boot it will just stay at the apple logo with the spinning bar.
I booted into the recoveryHD with COMMAND+R and launched disk utility, I then proceeded to click "repair disk" on Macintosh HD.
It hangs for a while but then says "The volume Macintosh HD could not be verified completely" and then says ERROR:Disk utility cant repair this disk, backup as many of your files as possible, reformat the disk and restore your backed-up files.
I then tried to "re-install OS X Mavericks" but I need an apple ID with Mavericks purchased (please note I am on a windows machine and cant do this).
I've tried calling 133 622 but apparently their phones aren't on from 9am-9pm as stated (It's currently 7:30pm).
This is turning me off Macs as this sort of stuff should not just "happen" and due to apples "no windows support" views I cant actually do anything.

Mavericks is a free OS yes? If theres a way I can get it as a purchase on my Apple ID I can download and restore. I was just wondering whether there was a way to restore from the recoveryHD
And as for the no windows support, their OS X utilities image for USB is only available as a .dmg so I cant use that tool to recover from the recovery partition

First Kernel Panic - failed Disk Utility volume repair - Help?

Hello!
Well, you've seen the subject. 2 nights ago, after a long day of iTunes, Photoshop, Final Cut Express, and Halo, my powerbook had it's first kernel panic. When? When I unplugged my Lexar JD Lightning flash drive. I had just copied about 200 MB of music onto it (to copy to my imac), and ejected it. Instant panic.
Well, after a reboot, I ran disk warrior on all of my external drives - 2 USB (Western Digital 120GB, Iomega Exite 80GB), my Seagate 400 GB combo drive (Firewire), with 2 volumes, and my 4G clickwheel iPod - well, it's FAT32, so it didn't check it. (For use copying files to our winbox)
It worked properly, until I tried to repair the Iomega drive. It froze. Force reboot.
So, now I ran disk utility on my internal drive. While it was running, Backup started, and everything locked up. Force reboot again.
It rebooted and loged in just fine, so I restarted to the OS X install DVD (the one that came with the Powerbook - 10.3.7). I ran disk utility on Macintosh HD (boot drive). Permissions verification showed a few "special permissions". Permissions repair worked just fine. Disk verification found issues, and repair didn't work. It gave the following error while running:
"Invalid leaf record count. Should be 1 instead of 302"
In big bold letters, repairs failed. Odd, it checked 2 volumes -
at the bottom, it said
"Repair attempted on 2 volumes: (green text) 1 HFS volume repaired. (next line, red) 1 volume could not be repaired.
Right above this, in the progress window, it stated:
"The volume Macintosh HD was repaired successfully"
So, what? Is the second volume the install DVD?
My powerbook is running just fine, so I ran backup again. (the .Mac backup application from Apple)
Then, I ran Tech Tool Deluxe (3.03) - included on the AppleCare CD that came with our Applecare subscription for my Powerbook. It found no issues at all.
So, i'm clueless. I have not noticed any other issues. At least, since the issue.
Before this happened, I've noticed a few glitches. One is that iTunes has slowed down, particularly when changing tracks. The other is the menu bar battery indicator - sometimes it disappears - rather, the indicator. The space that it occupies in the menu bar remains empty, until you click on it - then it shows up fine. What's odd is that it's only the text - it's otherwise just fine.
What happened before the issue began? Well, I installed a new PNY ram card back around Easter - if that's the culprit, shouldn't it have shown an issue before now? Second: Installs. A few widgets, and a couple of applications: OS 10.4.7 and all other updates Software Update had to offer, Toast 7.1 update, Comic Life's new Universal version (a minor update, actually), Microsoft Office update (heh, probably that), and the trial of Salling Clicker - it's quite cool - Macworld (Aug 06 - new issue) gave the right rating (5 mice!). I dont' run permission checks enough, I know.
A while back, (like 10 months ago) my Powerbook wouldn't go to sleep. It turned out that it was one particular USB 2.0 hub - disconnecting it solved the issue. Its not unlike how my Seagate FW drive will keep my iMac from booting properly every now and then.
So, here are the questions:
1. What is the "leaf record count"? Is it very critical? Is it part of the physical HDD, or the system?
2. Powerbook's running fine, and no other issues. Is it okay to run?
3. If I need to repair/reformat (eventually), will it be sooner or later?
4. This seems rather odd, and very intermittant. How do I find out what the issue is?
5. What is the second, mysterious volume? Macintosh HD is not partitioned. (Could it be Classic?)
6. if the SMART status of the internal drive reports just fine, could it be missing something?
Thanks,
Daniel

Techtool Deluxe you want to be running version 3.0.4. Version 3.0.3 is not compatible with 10.4 and may be causing the leaf count issues. Here's the link to get an updated Techtool Deluxe:
https://support.apple.com/techtooldeluxe/main?id=dl
My suggestion is to start to simplify everything here. Leave everything disconnected from the machine, and boot off the Disk Warrior 3.0.3 CD, and repair the internal drive first. Use the Option key to boot:
http://docs.info.apple.com/article.html?artnum=106178
Once you are able to do that, then see if you can repair the external drives.
RAM issues can crop up at anytime, and without warning. No test can detect all bad RAM, but once detected, then you know it is accurate.

IMac Disk Utility Prob/Reinstalling OSX?

Hi guys,
I would have been most grateful to you if you could give me some tips on the following situation.
I have got some sort of a bug in my iMac G5 Ambient Light Sensor: it turned off 2 times, and the Disk Utility said I had to repair the volume, well, the usual stuff, you know: 'The underlying task reported failure...' and blablabla... I have tried to startup from the OSX DVD from my MacBook, since it was the closest version to what I have on the iMac [10.4.8], but it gave me the Kernel Panic and asked to restart. Now I am thinking of reinstalling the whole system, since what I've got on my iMac isn't that vitally important and I can backup some files on my Book, but I would like to know what you could advise me. Maybe there's some way round? Is it normal to reinstall the OSX from my MacBook DVD? Will it be fine? The problem is that I don't have an original CD that came with the iMac. :-/
I can also try to startup from another person's MacBookPro and try to fix the problem with the Disk Utility, but perhaps it won't work? Can it be that I'll have more bugs in the future? Probably it's better to reinstall and all the bugs will be erased? Anyone had anything of a kind?
Oh, yes, and I would like to know if the Archieve option in the OSX Install does actually save the programs the way they are, and if they'd need any kind of installation afterwards, after the OSX installation.
Thanx for any possible assistance!
MacBook Mac OS X (10.4.8)

Welcome to Discussions - no, you cannot start up from your MacBook install disc, it has a totally different structure. You need an install disc for the G5 ambient light, Apple will sell you one, or perhaps you can find it on eBay, but it must be for the ambient light, and no other model.
You can start in target disk mode using your MacBook.
If you do an archive and install, and check "preserve user settings and preferences, all your apps and settings (well, most of them) will be saved, here are the instructions.
Pplease let us know how you make out,

Unresponsive iMac - disk utility repair unsuccessful

My iMac has been running slow for several months, but it got ridiculously slow recently, and now it will not start up - stuck on the screen with the spinning clock. So I stuck in the INstall Disk and did a 'hardware check' - it said all was ok. I tried the First Aid disk utility to repair it, and it said "Error: THe underlying task reported failure on exit". Before that, it said "Incorrect number of thread records", "invalid node structure" and "volume check failed".
Do I need to re-install the OS? I have a backup of the hard disk, but I haven't backed it up in about 2 months, so I would hate to lose 2 months worth of files.
Any ideas?

Hello es:
Welcome to Apple discussions.
If Apple's disk utility fails to fix problems you have two choices:
1. Use a robust third party utility. I have DiskWarrior (pricey at about $90 from Alsoft). DW is the +"gold standard"+ of directory repair.
2. Do an archive and install. Erase and install should be reserved for disasters. An archive and install will preserve your files, programs, and settings while installing a fresh OS X (you would, of course, need to run software update to bring everything to current levels).

bob:
Disk Utility reports "Underlying task reported failure" when repairing a volume is a serious directory error which Disk Utility cannot repair.
•I suggest you read through the article.
•Then, if you do not have an up-to-date backup, it will be a good idea to try to save as much as you can of your data.
•The article suggests using a third party utility. Disk Warrior and Tech Tool Pro are the best utilities for this job. You will need to get one of them and run it, by booting from the CD, or installing it on an external firewire drive or on a second Mac which you can then run in Firewire Target Disk Mode.
Please do post back with further questions or comments.
Good luck.

IMac disk utility not reading any FAT32/NTFS related partitions/CD/flash drives

Hi everyone!
I'm trying to access my drives and later on install bootcamp and windows on my iMac. At moment I can only start the iMac in safe mode (long story, if interested check out iMac 27" (late 2009), freezing - List of solutions tried). Any steps taken so far to read and format other drives has been in Safe Mode.
Problems:
- any formats except Mac OS X extended gets greyed out in Disk Utility.
- Not able to read/mount flash drives, external drives or CD's with any other formats.
Solutions tried:
- Tried to format using OSX on current iMac, MBP and PC and no change or luck.
- Tried on other machines and it works great. So it's related to my iMac.
- Disk Utility try to Mount drive/partition - getting error "The disk "BOOTCAMP" could not be mounted"
- Installed Paragon NTFS but no difference.
- Disk Utility no disk error reported
Searched on internet and forums for a solution w/o any luck. Haven't found anyone with similar problems or I'm using wrong keywords. Haven't found any Knowledge Base about other formats is disabled in Safe Mode state so it can't be that either. Below is a picture that shows any other partitions than mac is greyed out.
Any suggestions or anyone encounter with this wierd behavior?

Disk utility repair doesn't repair os disk

Disk utility (13) keeps saying
Invalid B-tree node size
The volume could not be verified completely.
and, once it has shown "updating boot support partitions for the volume as required", says "This disk needs to be repaired. Click Repair Disk."
But I'm getting the impression that clicking repair disk does not help - even after about ten times, the messages stay the same.
I can't re-partition the disk as all those options are grey, even though I'm booted from an external USB drive.
The machine is a MacPro, early 2009, OS X 10.9.3 (13D65), disk is encrypted journaled HFS+, used to have a Bootcamp partition a few years ago but is now a single partition.
I can probably no longer boot from this drive, each time takes longer and last time took almost thirty minutes, so I'm really looking of a good fix.
Any suggestions?
Regards,
Bob

Eric,
I've first tried Disk Utility when booted from the Recovery of the disk itself. Didn't help and also didn't offer a re-format option.
I've then made a USB bootable, booted from that and tried Disk Utility - didn't help.
I've then booted from the Recovery of the USB and tried Disk Utility - didn't help.
I've since used diskutil reformat on the command line and found to my surprise that the disk is now empty but the "Invalid B-tree node size" remains.
It seems reformatting does not reset the indexes of the disk
And every now and then I still see a remark about the "Windows boot.ini files" - which I also wouldn't expect after reformatting.

Disk Utility really doesn't repair disk

When repairing permissions disk utility finds and repairs permissions that are not correct.However,when the repair permissions utility is ran again it finds the same errors and says it fixes them again and again and again.What gives? Thanks.

Have you visited [Disk Utility's Repair Disk Permissions messages that you can safely ignore|http://support.apple.com/kb/TS1448]?
And, why are you repairing permissions? Do you have file access problems? Are applications reporting that they can't find or open some files?

Disk Utility Volume name issues in 10.10.1

Hi
I recently updated to 10.10.1 in the hopes that it would resolve the wi-fi issues, which it only partially did. Disregarding that, I did a usual disk verification that I tend to do after each major upgrade, and found that while verifying, the details box showed the volume name as what I believe to its unique identifier instead of its volume name.
So instead of showing: "The volume Macintosh HD appears to be OK"
It instead shows: "The volume (long string of numbers and letters)-(three shorts string of numbers and letters)-(a final long string of numbers and letters)" appears to be OK
I'm wondering if anyone else has encountered this, or if anyone knows if this is a problem.
Thanks

hello,
my personal opinion is that the Tasks part in BlackBerry10 serves only one purpose: bring compatibility with Outlook/Lotus through BES connectivity.
If your device is not linked to a BES server, I strongly advise you to look at the dozens of free and paid apps that manage tasks with much more efficiency than the Remember app.

Disk Utility doesn't see Time capsuleDisk

I'm trying to migrate a backup did with Time Machine to a brand new Airport Time Capsule Disk.
This is for don't loess the previous backups having ones new.
I got some information and it looks I should connect both disks (old HD and new Time capsule) to my Mac , then restore the new one using as source the old backups.
The matter is that DISK UTILITY APP doesn't see the Time Capsule disk .
Who may help me in doing this operation?
Many thanks
ivano

Niel, many thanks for your reply. I've gone trough the instructions you've indicated but I've not found my case.
Let me try to explain my situation
Till now I did the backups in an external Western Digital HD (MyBookLive) using Time Machine.
The disk was gonna be full so I bought a Time Capsule bigger than the WD I had.
My intention was to continue to do backups using TimeMachine on the new TimeCapsule KEEPING ONLINE the old backups.
I read that I should use DISK UTILITY APP and restore the old spares bundle file into a new one locate into the Time Capsule.
My problem is that using DISK UTILITY I cannot see both the WD Disk neither the Time Capsule .
Many thanks in advance for your support
ivano

Disk Utility hangs ("not responding") when attempting to Repair Disk on Time Capsule sparsebundle. Help.

I am trying to improve the performance of my Time Machine backup and retrievals via my 2nd Gen. Time Capsule from my iMac Core 2 Duo hard drive with SL 10.6.8. The incremental backups generally take 20 - 40 minutes each hour generally with fewer than 100 MB of data being backed up. I have read through numerous threads on these forums about Time Capsule and Time Machine issues as well as the very helpful Pondini site (http://web.me.com/pondini/Time_Machine/Home.html) and have tried many other suggestions (listed below), but have been unable to attempt a Disk Utility repair disk on the Time Capsule sparsebundle file.
After locating the sparsebundle 'file' in the finder under Shared/TC/Data, I am only sometimes able to drag the sparsebundle into the Disk Utility volumes and disk window. About fifty percent of the time, Disk Utility hangs when attempting to drag in the sparsebundle. If I am able to get it listed and click on "repair disk", then the beach ball begins to spin and nothing happens. This occurs whether or not I first use AirPort Utility to "Disconnect All Users" from the Time Capsule. I have given it over one hour to attempt the repair disk, but nothing happens, i.e., not a single message shows up in the detail window. The beach ball just spins, and Disk Utility shows up in red as "not responding" under the Force Quit menu.
Also note that on my new Macbook Air, Time Machine runs quite quickly via this same Time Capsule from my new Macbook Air using OS X Lion (which seems to indicate that the Time Capsule drive itself is OK).
I would appreciate any tips on getting Disk Utility to run "repair disk" on my sparsebundle, as I seem to have exhausted most other options (see below) for improving Time Capsule performance -- aside of course, from wiping the Time Capsule clean and starting all over.... (which I really don't want to do, and from what I've read, has not helped some people who've tried this anyway).
Many thanks!
Although I would like to focus this thread on the Disk Utility / sparsebundle "Repair Disk" problem, I should mention that I have tried the following other things:
1. Repaired disk permissions on my hard drive
2. Used Disk Utility to run "repair disk" on my hard drive after starting up from a SuperDuper external backup
3. Run DiskWarrior on my hard drive, again, from a separate startup disk
4. Did the "full reset of Time Machine", a la Pondini Troubleshooting #A4
5. Changed my computer and Time Capsule names to simple short names with only alphanumeric characters and no spaces
6. Ensured that my Time Capsule is being accessed only via ethernet
7. Relaunched the finder
8. And finally, attempting to use Disk Utility to repair the sparsebundle - thus the nature of this post

OK, no takers out there, but I answered my own question (sort of).
The answer is that even though Disk Utility shows up as "not responding" under the Force Quit menu and appears to hang, it is actually still working. A bit of patience shows that after about an hour, my Disk Utility was able to show the 1.44 TB Time Machine sparsebundle from Time Capsule in the disk window on the left hand side. Once this appeared, I was able to click on "Repair Disk" (note that prior to doing this, I had to "Disconnect All Users" from my Time Capsule using the Airport Utility program; otherwise you will get a "could not unmount disk" error). Again, the Repair Disk function appeared to hang Disk Utility as it showed up as "not responding" under the Force Quit menu. However, after about 8 hours, Disk Utility did run the entire Repair Disk protocol on the sparsebundle. The results DO NOT show up in the Disk Utility details window - so even if you are patient enough to let it complete, you will not see anything and may think that nothing happened. However, you can find the familiar results of the Repair Disk function by looking on Console - find the "DiskUtility.log" under Files: ˜/Library/Logs.
Unfortunately, I was hoping to find a problem that would have been subsequently repaired which would result in dramatically increased Time Capsule speed, but this was not the case. Disk Utility showed everything to be "OK" and I am stuck with a very slow Time Capsule....
(And of note, my new Macbook Air (OS Lion) Time Machine functions blazingly fast on both backup and retrieval to and from the very same Time Capsule - even though, these are occuring wirelessly via AirPort -- granted the size of this sparsebundle is an order of magnitude smaller at this point, i.e., only 10 GB right now)
Would still be happy to hear of any similar experiences or tips on getting Time Capsule to work more quickly.

Disk Utility will not verify disk because, "The underlying task reported failure on exit." Now what?

Disk utility will not verify disk because, " The underlying task reported failure on exit." The "repair disk" button does not light up. The report says that repairs need to be made to the hard drive. I have already checked permissions. What do I do next to get the repair process started? Also, I cannot find a defragmenting drive option in Disk Utility. Doesn't it exist?

You need to boot from the install DVD (or a clone of your internal) to run Repair Disk. Repair Disk will be grayed out, dimmed, because you can't repair from the same volume you are booted from.
EDIT: No, you do not yet need to use Disk Warrior or Tech Tool or do any reformatting. These steps might become necessary only if Repair Disk fails.
Unless you have very large video files, for example, there is no need to run any defragmenting utility. OS X does it all by itself on the fly.
Try Disk Utility
Start from your Mac OS X Install disc: Insert the installation disc, then restart the computer while holding the C key.
When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
Click the First Aid tab.
Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
Select your Mac OS X volume.
Click Repair. Disk Utility checks and repairs the disk.
If you don't have the install DVD, try a Safe Boot. Hold the Shift key down at startup and give it much more time to boot than usual. It's trying to repair the drive directory.
