My Mac's Recovery HD Comes Up In Disk Utility

When I Turned My Mac On Today I Noticed That My Recovery Partition Was Showing On My Desktop And Disk Utility What Do I Do?

It Also Stops Me From Being Able To partition My Drives.

Mac Pro not recognizing bootable DVDs and Disk Utility giving odd results.

My issue is complex, but I'll try my best to explain it as I can.
One has been resolved it seems, but I am including it so that the whole issue can be seen in context.
Friday, May 16, 2014
Last night, after rebooting my Mac Pro from my Bootcamp partition (I'm using Windows 7 Professional if that information is helpful) I received a kernel panic upon Mac OS X booting (Mac OS X 10.6.8).
My first action was to launch Disk Utility to verify the Mac HD, verify was stopped by disk utility citing that I should insert my Mac OS X install DVD and repair the disk.
I tried booting from my Snow Leopard install DVD. After the grey Apple logo appeared with the gear spinning below it remained for roughly ten to fifteen seconds (a little long) — then the Apple logo changed to. A grey prohibitory sign (circle with a diagonal line through it, the spinning gear remained. — I tried booting from the Snow Leopard DVD a few time, same result.
Following this I tried booting using Disk Warrior, same result again.
I tried booting both the Snow Leopard and Disk Warrior DVDs in both my upper and lower optical drives, with no change.
I decided to leave the issue and call Apple Support in the morning
Saturday, May 17, 2014
This morning I woke my Mac Pro from sleep, opened Disk Utility and tried verifying the hard drive to see if it was temporary — same result, 'please insert the Mac OS X install DVD and repair the drive.' — I also tried booting the install DVD again with no result.
I then booted my Mac into Safe Mode to check my hardware.
Upon opening Disk Utility and verifying my Mac HD — the result "Macintosh HD appears to be OK", rand the test again to see if this was an anomaly, but disk returned another pass.
I performed a normal restart of my system, although Finder was a little slower to load than normal, the system booted correctly. — I then launched Disk Utility and verified the Mac HD, it returned another pass.
This confused me, after a call to Apple Support the tech explained that 'sometime a Safe Mode boot will fix problems because it disables all non-essential processes when booting. — That makes sense to me.
However.
The issue of my Mac not recognizing bootable DVDs remains — it reads disks correctly, it just will not boot them.
Other steps I have taken to try and resolve this remaining issue.
1. a PRAM reset. — No change.
2. an SMC reset. — No change.
3. Removal of newly installed RAM. — I have tried both running the old and new RAM separately, no change using either combination.
4. Running bootable DVDs in different optical bays. — No change from both bays.
a. My upper drive is an MCE Blu-Ray/DVD combo drive, but I have booted from this drive before. (Less than six months old.)
b. My lower drive is LG DVD-RAM combo drive, I have also booted from this drive before. (Over one year old, replacement for an Apple optical drive.)
None of the above steps have helped, I still cannot boot from my optical drives — I always receive a prohibitory sign shortly after the Apple logo.
Other system information:
Mac OS X 10.6.8
8GB of RAM (4 x 2GB)
500GB Western Digital Caviar Blue HDD (less than a year old, boot drive for Mac OS X 10.6.8)
1TB Samsung HDD (for data storage and also containing Bootcamp partition)
2TB HDD (cannot remember manufacturer, contains Time Machine backups, as well as data storage)
ATI Radeon HD 5770 with 1GB of VRAM
Sorry for the long post but I really need to be able to boot from my optical drives.

Update: found an old Mountain Lion installation USB flash drive I created a while back.
I am able to boot from the ML USB flash drive, but am still unable to boot from my either my Snow Leopard Install DVD or my Disk Warrior DVD. — I have verified both DVD and they pass verification tests.
This leads me to believe that the problem resides either in the Mac, or in BOTH the Snow Leopard and Disk Warrior DVDs.
Since I am able to boot from a USB drive, I will look into the possibility of creating a bootable Snow Leopard drive, and perhaps also a Disk Warrior drive — at least until I can resolve the 'not able to boot from DVD' issue.

Mac OS X 10.4. 11 Disk Utility - Cannot find Brand New HardDrive

I've recently swapped Computers with my sister, and I felt a little "upgrading" was in need of the PowerMac. I went and got a brand new HD, and Ram. When I went and changed everything around, I got to the disk Utility and now it wont even pull up my HD. - Long story shot

From your computer info posted and the fact that you're planning on installing OS 10.4.11, I assume that you have a Blue & White G3. If so, there is a potential problem, if you've connected a large capacity drive to the onboard IDE controller in a B&W G3 having the first revision motherboard. Drives larger than 30-40 GBs can have stability issues, so that a Mac-compatible ATA controller PCI card must be used, such as the (now-discontinued) Acard AEC-6280M. Although a separate issue, an ATA-133 controller card also takes care of the 128 GB limit mentioned by Grant in his post, by recognizing the entire capacity of large drives. If you have a Blue & White G3, post back for a link to an article that can be helpful in determining whether you have the first or second revision motherboard. Incidentally, the dedicated Forum for the Power Mac G3s can be found here.

Mac-formatted external HD only access with Disk Utility

Hello!
I read a lot about problems with Mavericks and WD harddrives. But i did not found anything about my problem:
- bought a new HD and formatted with Disk Utility
- copied all important data to it, all fine
- next day for my surprise i couldn´t see this HD in Finder
- looked in Disk Utility and the HD is there
- if i click on the drive and "open" then i can see it in finder and have access to all data, but if i click on "reveal in finder" i can´t see it!
- i started CarbonCopyCloner and did a complete backup to a new second backup HD, CCC recognized the HD and everything worked fine
- now the backup HD has the same problem, i can see it only in Disk Utility
- it seems that the error moved from one drive to the other, so my guess is it has nothing to do with brands or a hardware failure
- i´m searching now for hours but i don´t find a solution
- i now have one (very important) data HD and a backup HD as a clone with the same problem
- all other HD´s i have are showing correctly in finder!
Does anyone have any ideas?

After hours of searching this is the solution:
Open Terminal, then
defaults write com.apple.finder AppleShowAllFiles TRUE
killall Finder
sudo chflags nohidden /Volumes/"Name Of Drive"
killall Finder
defaults write com.apple.finder AppleShowAllFiles FALSE
killall Finder

Mac sees iPod as external hd in disk utility???

(10-3-06)
Note: I also posted this in the iTunes discussion, but no one responded.
(10-2-06)
I've been having problems w/my iPod recently. I'd plug in my iPod into the dock i have and my mac wouldn't recognize it. and since it says "do not disconnect", i was scared to unplug and check out what was going on.
Long story short: i've done all the recommendation steps: resetting it does help, but still doesn't get recognized in iTunes or my desktop. Yestersay, i took it in ym car as usual and was listening to it. no problem, plugged it in, no problem,. Today, i was messing w/my computer and had to reset it. the iPod was already plugged in, but nothing came on the desktop. checked disk utility and the ipod looked like it was one of my external hds, but nothing came up on iTunes or my desktop still.
Note: Because of iTunes 7.0 being an utter failure, i switched back to 6.0.4.
right now, it's plugged into my AC adapter. I'm just wondering i what i did wrong, if anything and if the NON-Recognition will continue if i plug it into my computer. plus, if i plug it in and the "do not disconnect" continues, but nothing shows up on iTunes or desktop. any help is appreciated.

any thoughts? i'm afraid of syncing my music cause i'll never get my iPod off my comp b/c "do not disconnect" warning.

I already upgrade to lion.Now I want to reformat it using recovery hd.There,I use disk utility to erase disk as usually done.Then,I click install mac osxlion,after validation done,it appear dwnld,but stuck..is that because i erase disk?wht shld i do?

plss, now my mbp running no os, help me is the problem is because i erase disk? what i should do right now?

Wow, thanks. It did the trick. So now I am confused, do you think I still need to take in my Mac to see if there are some problems with the hard drive, or do you think I'm in the clear. I was going to get a new hard drive installed, because I thought that was the issue seeing as I couldn't access it during safe mode.

Help! Disk Utility failed to restore my 750gb Mac HD

Here's the story. A couple weeks ago I successfully installed Windows 7 Home as a bootcamp partition using Disk Utility, not Bootcamp Assisstant, I clicked on my 750gb mac drive, clicked on partition, clicked the "+" symbol to split the HDD into a second partition, allocated 200gb for this Windows 7 partition remaining 550gb for Mac HD, made it into MS-Dos Format so I can format it into NTSF during the Windows installation; everything was working fine, I even was successfully running Parallels 7 with it.
So here's my problem, the other day I purchased Windows 7 Professional, decided I wanted to do a complete new installation so I went into my Mac OS X Lion and went into Disk Utility, deleted the Windows partition, then dragged the corner of my Mac HD putting it back to 750gb. Now my bootcamp partition of Windows 7 HD is deleted so I went ahead and hit the "+" to create a partition for Windows 7 Pro HD, it gave me a Failed Error message, so I went into my Mac OS HD and repaired Disk, even hit the set permissions button), those both didnt fix my problem of creating a partition.
So i go into bootcamp assistant and went through the process, i already have the mac drives, hit continue, then it showed me what i can allocate for Windows. It tells me I only have 345gb to allocate a Windows partition, but I should have 200gb ontop of that. My total HDD is 750gb and I only have 550gb available for me to use :(. How do I get the remaining 200gb i used from my old windows partiton I already deleted. By the way, I already allocated 750gb to my Mac HDD freeing up all the free space.
Can anyone help? I can send screenshots if needed.
Thank you!

Carbon Copy Cloner your Lion partition to a HFS+ Journaled formatted external powered drive, "hold option boot" from it, check it out and then use Disk Utility there to erase the entire drive and reformat, reverse clone.
You'll loose the Lion Recovery Partition, but you got clones on external drives.
You have to reformat the whole drive, as the GUID partition map is off and needs to be updated correctly.
Also you can download the Lion Recovery Disk Assistant in advance and/or create "hold c" Lion boot DVD's from the MacAppStore Lion installer by holding option key and clicking on Purchases and downloading the Lion installer again and following these instructions.
http://eggfreckles.net/notes/burning-a-lion-boot-disc/
Also just in case you need it as you can always boot your Snow Leopard disk and install then upgrade to Lion on a blank drive without a Lion Recovery Partition.
http://www.walterjessen.com/make-a-bootable-backup-snow-leopard-install-disc/
Once you got Lion up, then Bootcamp the Windows 7 Pro.
You can try WinClone to clone Windows, I don't know how well it will work with Lion, it hasn't been updated recently, your best bet would be to fresh install.

Your backups may be hopelessly corrupted, but there's a chance an (expensive) 3rd-party Disk Repair utility might be able to fix them. For the moment, eject and disconnect the TM drive and try to repair the internal.

Do that first.

"Disk Utility has lost its connection with the Disk Management Tool and cannot continue. Please quit and relaunch Disk Utility." Trying to format my iomega external HD for use with Mac

Hi. Trying to connect iomega ext. HD. i have to reformat for Mac. When i plug in & go to Disk Utility,the external shows up and i'm supposed to click "partition". When i do, a box comes up saying ""Disk Utility has lost its connection with the Disk Management Tool and cannot continue. Please quit and relaunch Disk Utility." I quit and relaunched, same results. After googling my question, i came up with this:
"Disk Utility has lost its connection with the Disk Management Tool and cannot continue. Please quit and relaunch Disk Utility."
(Quitting and reopening Disk Utility does not help.)
The following also appears in Console log:
*** malloc[419]: Deallocation of a pointer not malloced: 0x290a410; This could be a double free(), or free() called with the middle of an allocated block; Try setting environment variable MallocHelp to see tools to help debug : for architecture i386 object: ./Applications/iTunes.app/Contents/MacOS/iTunes malformed object (unknown flavor for flavor number 0 in LC_UNIXTHREAD command 27 can't byte swap it)
Workaround
Quit Disk Utility.
From the Finder's Go menu, choose Go to Folder....
Type the following, then click OK: /Library/Receipts
Temporarily remove these iTunes receipts from /Library/Receipts (sort the folder alphabetically as a list):
iTunes.pkg
iTunes4.pkg
You can put them on the desktop, for example. Do not remove iTunesX.pkg or iTunes Phone Driver.pkg.
Open Disk Utility and repair disk permissions again.
Quit Disk Utility.
Put the removed iTunes receipts back in /Library/Receipts.
Note: This issue does not affect Disk Utility's verify or repair disk features.
All seemed good, for a moment, until, upon going back to Disk Utility after removing itunes4.pkg and putting on desktop (i did not have itunes.pkg to remove) the same thing was happening. When i highlite my iomega ext. on left of page, disk perrmissions is grayed and does not allow me to click on it. Same problem from the start. Can somebody please help me out here? That would soooo awesome. Thanx!

i'm just scared i will do something wrong on my own and lose my data.
You shouldn't be scared of that, because you should already have backups. If you don't have backups, then backing up is the first priority.
Insert the Snow Leopard DVD and restart. When you hear the chime, hold down the C key and keep holding it until the Apple logo appears on the display. You should now see the language selection screen. Select your language, then choose Utilities > Disk Utility from the menu bar. In the Disk Utility window, select the external drive (not the internal). The drive may already have a data partition, in which case there will be another icon below the drive icon. Choose the drive icon, then select the Partition tab. Create a single partition with the default options (GUID partition table, Mac OS X Extended Journaled).
When the partitioning is done, select the startup volume on your internal drive in the DU window. Select the Restore tab. Drag the icon of the startup volume to the "Source" field. Then drag the icon of the newly-created volume on the external drive to the "Destination" field. Make sure you have this right. Then click the Restore button, and the data on your startup volume will be copied to the external drive.

Why can't I select Disk Utility when I start in recovery mode?

Disk utility varification of HD detects requirement for repair and directs recovery mode startup. When I startup in recovery mode I cannot select Disk Utility or any of the other options. Likewise, I cannot select File, Edit, or any other options across the top of the screen? Any ideas?

The menu comes up, but I can't select any of the options or the continue button. I can move the arrow by moving my finger on the touch pad, but nothing is touch sensitive.
The menu box has a blue line around the inside of it when it comes up, as though it has been selected. I'm not at means anything.

Perhaps, since you are under warranty, they may have a boot disk to attempt to run disk utility and see if the problem can be repaired before resorting to reformatting. Disk error may occur because of a number of issues (installed software, crashes, shutdowns, physical movement of the drive while disks spinning, etc.)
In addition you may want to boot in the single user mode to access the FSCK command as follows: The following is from the Apple support site
Mac OS X: How to Start up in Single-User or Verbose Mode
You may use a key combination when starting up the computer to enter single-user mode or verbose mode, either of which can be used for troubleshooting and in software development. This document applies to Mac OS X and Mac OS X Server versions 10.0 and later.
Steps to Enter Single-User or Verbose Mode
1. Shut down the computer if it is on.
2. Press the power button to start the computer.
3. Immediately press and hold the Command (Apple) key and one of the following:
the "s" key for single-user mode.
the "v" key for verbose mode.
4. To exit single-user mode type: reboot
5. Press Return.
You have successfully entered single-user or verbose mode when you see white text appear on the screen.
Then you may try to repair as follows using the FSCK
fsck is a command-line utility that may be able to verify and repair a disk. If you can successfully start up in Safe Mode or use Disk Utility while started up from a disc, you don't need to use fsck. However, here are some situations in which fsck may be necessary.
Your Mac OS X disc isn't available.
Your optical drive isn't available.
You can't start with a Safe Boot.
Tip: If you use a Mac OS X Extended (Journaled) formatted volume, such as with Mac OS X 10.3 or later, you probably won't need to use fsck. If you do use it for any reason, please be aware that benign error messages can appear.
If you're not sure how your volume is formatted and you can't start up from your Mac OS X volume to find out, type the following command in a command-line interface and then press Return: diskutil info /
If you see "File System: Journaled HFS+" returned, you have a Journaled volume.
To use fsck, you must run it from the command line. Unlike using your mouse to open an application to do something, you'll need to type a text command at the prompt (#) to tell fsck what to do. The Terminal application (/Applications/Utilities) and single-user mode are two examples of command-line interfaces in which you can type such commands. To use fsck:
Start up your computer in single-user mode to reach the command line.
Note: If necessary, perform a forced restart as described in the Emergency Troubleshooting Handbook that came with your computer. On desktop computers, you can do this by pressing the reset/interrupt button (if there is one) or holding down the power button for several seconds. On portable computers, simultaneously press the Command-Control-power keys. If your portable computer doesn't restart with this method, you may need to reset the Power Manager.
At the command-line prompt, type /sbin/fsck -fy
Press Return. fsck will go through five "phases" and then return information about your disk's use and fragmentation. Once it finishes, it'll display this message if no issue is found:
** The volume (nameofvolume) appears to be OK
If fsck found issues and has altered, repaired, or fixed anything, it will display this message:
*** FILE SYSTEM WAS MODIFIED ***
Important: If this message appears, repeat the fsck command you typed in step 2 until fsck tells you that your volume appears to be OK (first-pass repairs may uncover additional issues, so this is a normal thing to do).
When fsck reports that your volume is OK, type reboot at the prompt and then press Return.
Your computer should start up normally and allow you to log in.
About live verification in Mac OS X 10.4.3 or later
In Mac OS X 10.4.3 or later, you can verify your Mac OS X volume while started from it. This is known as live verification, and can be used in three different ways.
Option 1: Verify your disk using Disk Utility while started from the startup disk. To find out how to do this, see this article. Please note that live verification does not involve any disk repair, so if verification finds something that should be repaired, start up from your Mac OS X Install disc and use Disk Utility as described above in "Try Disk Utility."
Option 2 (advanced): Use the command line and the command-line utility, diskutil.
Start up your computer and log in as an administrator.
Open Terminal (/Applications/Utilities).
At the prompt, type the following command and then press Return:
diskutil verify /
Note: Don't use this method to check non-startup volumes.
You should see messages such as the following during the disk check:
Could not unmount disk for verification, attempting live verify
Started verify/repair on volume disk0s3 Macintosh HD
Checking HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Checking multi-linked files.
Checking Catalog hierarchy.
Checking Extended Attributes file.
Checking volume bitmap.
Checking volume information.
The volume Macintosh HD appears to be OK.
Mounting Disk
Verify/repair finished on volume disk0s3 Macintosh HD
Option 3 (advanced): Use the command line and the fsck_hfs -l command.
Start up your computer and log in as an administrator.
Open Terminal (/Applications/Utilities).
At the prompt, type the following command and then press Return to determine your filesytem ID:
df -hl
Look for some lines of text that look like this:
Filesystem Size Used Avail Capacity Mounted on
/dev/disk0s3 37G 20G 17G 55% /
/dev/disk0s5 37G 37G 641M 98% /Volumes/Storage
Make a note of the first "disk" name that appears after /dev/, such as "disk0s3." This is your filesystem ID for your startup volume.
At the prompt, type the following command and then press Return:
df -hl
Then type the following command, where "disk0s3" is your filesystem ID you noted in step 4, then press Return:
sudo fsck_hfs -l /dev/disk0s3
When prompted, enter your admin password, then press Return to begin the verification.
You should see messages like these during the disk check:
** /dev/rdisk0s3 (NO WRITE)
** Root file system
** Checking HFS Plus volume.
** Checking Extents Overflow file.
** Checking Catalog file.
** Checking multi-linked files.
** Checking Catalog hierarchy.
** Checking Extended Attributes file.
** Checking volume bitmap.
** Checking volume information.
** The volume Macintosh HD appears to be OK.
Additional Information
If you're interested in UNIX-style command-line syntax, here's a look at how a couple of flags used in our instruction can influence fsck:
The -y flag: Tells fsck that you want to answer "yes" to all questions about fixing, repairing, or salvaging information. This is the optimal approach, as answering "no" to any question causes fsck to stop. You cannot determine that all necessary repairs have been made until fsck completes and gives its final report.
The -f flag: Forces fsck to check "clean" filesystems when preening.

Does Your Disk Utility App Stop Running Under Mac OS 10.9 - Mavericks

I am using a 2012 MacBook Air running Mac OS 10.9 - Mavericks. The Disk Utility app Verify function stops running, most often during the "Checking Volume Information" part of the test, and does not display any results. The app does not crash: I can run Verify over and over. The app simply stops running. Does anyone else have this problem?

I have a Drobo (2nd Gen) attached to my early 2009 Mac Pro via Firewire and it consistently has this problem with the Disk Utility app on Mavericks.
Maybe there's a timeout on the Disk Utility.
It seems that diskutil and fsck on the command line work.
First, get the device identifier for the volume you want to check:
bash-3.2$ diskutil list /Volumes/Drobo
/dev/disk5
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *17.6 TB    disk5
   1:                        EFI EFI                     209.7 MB   disk5s1
   2:                  Apple_HFS Drobo                   17.6 TB    disk5s2
then, use diskutil to verify the volume:
bash-3.2$ sudo diskutil verifyVolume /dev/disk5s2
Started file system verification on disk5s2 Drobo
Checking file system
Checking Journaled HFS Plus volume
Checking extents overflow file
Checking catalog file
Checking multi-linked files
Checking catalog hierarchy
Checking extended attributes file
Checking volume bitmap
Checking volume information
The volume Drobo appears to be OK
Finished file system verification on disk5s2 Drobo
You can also use fsck in debug mode if you like more verbose output. Here I first unmount and then use the raw device:
root# diskutil umount /Volumes/Drobo
Volume Drobo on disk5s2 unmounted
root# fsck_hfs -d -l -f /dev/rdisk5s2
** /dev/rdisk5s2 (NO WRITE)
        Using cacheBlockSize=32K cacheTotalBlock=98304 cacheSize=3145728K.
   Executing fsck_hfs (version hfs-226.1.1).
** Performing live verification.
** Checking Journaled HFS Plus volume.
   The volume name is Drobo
** Checking extents overflow file.
** Checking catalog file.
** Checking multi-linked files.
** Checking catalog hierarchy.
** Checking extended attributes file.
** Checking volume bitmap.
** Checking volume information.
** The volume Drobo appears to be OK.
        CheckHFS returned 0, fsmodified = 0
Then remount:
root# diskutil mount /dev/disk5s2
Volume Drobo on /dev/disk5s2 mounted
You should really read the fsck man page if you go this route. There are many options and many ways you could accidentally do something you don't intend to do.
Enjoy!

Disk Utility works for FAT but fails for Mac OS Extended

Hi Folks,
I have a 2TB WD My Book drive that I am trying to format as Mac OS Extended for Time Machine. Disk Utility will cheerfully format it as FAT (the FAT drive shows up in finder and seems to work fine), but won't format it as Mac OS Extended. I'm trying to figure out whether this is a hardware error, or whether I am doing something wrong.
To format it for Mac OS Extended, I am going into the partition tab, removing the current (FAT) partition, and adding a new Mac OS Extended partition. When I do this, Disk Utility shows the new partition as "grayed out" and it does not mount in Finder.
If I run Verify and Repair, I get the following errors:
Verify and Repair volume “Untitled 1”
Checking Journaled HFS Plus volume.
Invalid node structure
Invalid B-tree node size
Invalid record count
Invalid B-tree node size
The volume could not be verified completely.
Volume repair complete.Updating boot support partitions for the volume as required.Error: Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
Am I doing something wrong here, or does this sound more like a hardware failure?
Thanks!

@kbd1: Yes, if I erase the disk from the erase tab and format it as MS-DOS (FAT) the disk works just fine. If I erase and format it as Mac OS Extended, I get the same errors listed above and it doesn't mount.
@Thomas: Yes, if I set the format to GUID I get the same errors. I've even tried setting up two partitions: one FAT and one GUID and the FAT one mounts and the GUID one doesn’t.
So, from both of your responses it sounds like hardware, which makes sense. What is strange to me is that it works as a FAT drive...

Guitar21,
your MacBook Pro has booted into its Recovery mode. From the OS X Utilities menu, select Disk Utility. On the left-hand side of the Disk Utility window, select your internal disk’s boot partition (typically called “Macintosh HD”). On the right-hand side, press the Verify Disk button if it’s not greyed out; if it is greyed out, or if it reports that errors were found, press the Repair Disk button. Once the verification/repair is completed, exit Disk Utility and select Restart from the Apple menu to restart in normal mode. Does it get to the login screen now?

TS4036 where does icloud store my mac osx recovery key?

where does icloud store my mac osx recovery key for file vault?

Note that you have to have specifically chosen to store the key with Apple at the time you created the FileVault encryption, and chosen security questions so that you can identify yourself when you come to retrieve it. If you did not store it with Apple in this way and do not have a record of it elsewhere then you cannot proceed. All this has nothing to do with iCloud and the process is not automatic.
