Disk Utility is refusing to open

Hi,
I recently decided to upgrade to Mountain Lion but I was planning on doing a clean install. The thing is that my disk utility refuses to open. I checked and its saved under application-utilities but the logo is the one of the paper, ruler, pencil and pen one (the one that usually appears when the program hasnt been recognized) and when i try to open it my dock moves a bit and but nothing else happens, their is no jumping logo, nothing. What do you think might have happened? How can I fix it? Could it be something dangerous? Also do you recommend doing the clean install? i am using a Macbook pro 13 inches from mid 2010 with Snow leopard 10.6.8 on it.
Thanks alot for all your help1

Try this;
In FInder go to the Go Menu
HOLD down the Option key to show the hidden Library Folder and mouse click on it at the SAME time.
The finder window will open the hidden folder.
Now navigate to the preferences folder and click to open.
Look for the following files
com.apple.ActivityMonitor.plist
com.apple.ActivityMonitor.plist.lockfile
Move both to the trash.
Reboot Mac and try to launch Activity Monitor again. those files will be recreated and the icon should have returned to normal.

Disk Utility: Application Fails To Open / Must Force Quit

Hi-
My Disk Utility application opens but hangs on the "Gathering Disk Information" screen and I get the spinning wheel of doom. I let it spin for minutes/hours and it doesn't seem to matter. I have to Force Quit to get out of it.
I searced for a preference file to try trashing it and creating a new one but no luck in my search by name.
Any help would be great. Thanks!

It sounds like it's hanging on the disk check.

Disk utility Failure/Unable to open Hard drive with a double click

After trying to use Disk Warrior for maintanance last week my entire hard drive crashed.
I've spent the last week rebuilding only to encounter a new problem..i can not open the hard drive with a double click.
I attempted to run Disk utility to diagnose the problem and was told that the "program had lost connection and was unable to verify/repair disk permissions...and was told to shut down disk utility, which i ran from the install disk...
Any suggestions aside from erasing and rebuilding the hard drive?
Any assistance would be greatly appreciated.
Thanks,
Victoria

Disk Utility App will not open

Attempting to initialize new Lacie External Hard drive and/or if I wish to fix Premissions, opening the disk utility does not complete its disk gathering info, thus recycling. I left it on for days, no completion.
Could this be due to not enough RAM?

Possibly if you had less than 256 and had Classic open at the same time.
If this Mac is the one with 512 in your tag-line, you should look elsewhere for the source of the problem.
There is a guaranteed-good version of Disk Utilities on the install CD, hidden on the menus inside the installer program. You boot from the CD (with XPostFacto if required for your set-up) and rather than choosing English as the default language, choose Disk Utility off the menus.

Disk read error, and Disk Utility won't open

Have a PowerMac G4 dual 800mhz, with two hard drives. Mac OS X 10.3.9 is installed on HD1. I use HD2 for miscellaneous files.
Using the Azureus bittorrent client, I'm getting "Error: Disk read error - Input/output error, read fails" in the Status column when trying to download something to HD2.
However, I'm able to upload files from HD2 for other users, and I'm also able to play video files that are stored on HD2 without problem.
The real issue is that when I went to see if I could fix anything by opening Disk Utility, it won't open. It goes into an immediate state of Not Responding. It won't listen to me when I tell it to Force Quit... I have to wait a long time, or restart the computer, to get it to stop showing up in the dock.
Any advice would be appreciated.

To repair a startup volume you must do the following:
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. Then select Disk Utility from the Installer menu (Utilities menu for Tiger.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now shutdown the computer for a couple of minutes and then restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger) and/or TechTool Pro (4.5.2 for Tiger) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.

Why does good disk utility image generate error message?

I created a disk image of a data cd using disk utility. When I open the dmg file I get the message:
"The disk image you are opening may be damaged and could damage you system. Are you sure you want to open this image?"
When I open the image there are no issues and the content is correct. Why is this message being generated and what can I do to keep it from happening?

Hi Burkely,
"The disk image you are opening may be damaged and could damage you system. Are you sure you want to open this image?"
This is a standard message ...

DISK Utility issue..Please HELP

OK I had a 200 GB Hard Disk that I was using on my Windows machine. Since I am a Mac Guy now, I decided to buy an external USB enclosure, and use this as extra storage space. I am using DISK Utility to first partition the drive (1 partition) and then proceeded to Erase with zeros (1 time). Last night when I started this process it estimated a completion time of 3 hours. A few hours later it estimated at 1 hour and 16 mins. That was 8 hours ago. I hear the disk making noise as if it is writing, but I do not see any progress.
I was doing a Mac OS Extended (Journaled) and had the Install Mac OS 9 Disk Driver option checked. Not sure what difference this makes as all I want to use this disk is for storing photographs.
Has the process failed and am I in an eternal wait state? Does it normally take this long? Should I keep it running for the next 24 hours just to see? Suggestions please...
Thx in advance.

Well it sounds like Disk Utility has hanged. Open up Activity Monitor Applications/Utilities. If it is hung it will be in red...I'm pretty sure, I don't really remember the last time an app hung on my machine.
If everything is fine, it might just be that it's a big drive and it takes along time.
BTW, it seems sort of backwards to me to partition and then erase. If I were I would erase the disk FIRST, using the format you described, and THEN partition.

Disk Utility's "Verify Disk" does not work

For some reason I am not able to run the "Verify Disk" option in the Disk Utility application. I open up Disk Utility, I can click on the button, and it begins. However, while it says it is verifying the disk, and the status bar appears (just shows it working, doesn't show a time remaining), it continues like this for an inordinate amount of time. Eventually, the entire computer freezes up; I can move the mouse, but nothing responds to keyboard or mouse clicks. I am forced to hold down the power button to shut-down.
To get more information I decided to run this command in the Terminal. This is what I get:
+mycomputername~ root# diskutil verifyVolume /+
+Started verify/repair on volume disk0s2 Macintosh HD+
When I press enter after typing the first line, the second line appears, and it appears but nothing else shows up. Eventually, like in Disk Utility (which makes sense), the entire computer freezes up. (I've waited hours)
Does anyone know why this tool might not be working? I know, when using the terminal, more dialog should show what it is working on, which is why I find it strange it doesn't even get past the "Started verify" point. For example, the following is supposed to show up eventually, but doesn't:
+Checking HFS Plus volume.+
+Checking Extents Overflow file.+
+Checking Catalog file.+
etc...
I used the command line to verify with fsck too. +(sudo fsck_hfs -l /dev/disk0s2)+ This worked. From what I can tell, the problems it generated were benign.
On a different note, the reason I want to do this is because I am trying to use Bootcamp Assistant 1.4 Beta to create an XP Partition (after I had to get rid of it due to a virus), but it gets stuck on the "Partitioning Disk", and the status (which doesn't show remaining time) just continues to stay the same after a few hours, eventually freezing the computer in the same way the Verify Disk does. See a theme here? I'm not sure if this is related or not.
So why does the Verify Disk tool not work for me? Anyone have any ideas? I'm hesitant to try to use the Disk Repair tool, without the Verify Disk tool working.
Thanks for any help! Oh, and Happy New Year!
Michael

For some reason that didn't cross my mind. I booted with the OSX installer disk, and used DU and the Verify Disk worked!
Oddly enough when it finished I got an error message. Maybe that's just because the Verify encountered errors. It said:
+First Aid failed+
+Disk Utility stopped verifying "Macintosh HD" beause the following error was encountered: The underlying task reported failure on exit+
Here's the results of the scan:
+Checking Catalog file.+
+Resereved fields in the catalog record have incorrect data+

+Invalid volume free block count+
+(It should be 13585467 instead of 13578598)+
+The Volume Macintosh HD needs to be repaired.+
+Error: The underlying task reported failure on exit.+
I'm going to repair the disk, only after I backup my data. Not sure if these problems are 'benign' or not. Maybe that will solve my Boot Camp problems, maybe not. If not, well, it's either a complete reformat of the drive, or I'll have to buy Leopard so I can get Boot Camp support.
Thanks for your help again! So nice to see something working right on my Mac, finally
Michael

Leopard and Disk Utility

Since installing Leopard 2 days ago, I find that "Disk Utility" will no longer open. has anyone else come across this problem? Does anyone have any advice on how to correct the problem? I use this frequently in order to carry out repairs to the permissions.
Thanks in advance
Diane

After upgrading to leopard I couldn't open disk utility from utility folder alias in finder, but found I was able to open it in the utility folder in the application stack in the dock. I replaced the utility folder alias in the finder and it opened fine after that... but there seem to be some bugs with disk utility and leopard... i.e. - it's very slow, doesn't show progress bar, and doesn't seem to be actually repairing anything at all. Hope this helps and hope the first leopard update comes soon.

Disk Utility Crashing - Dyld error

This is a FYI for a problem I solved...
Symptoms: Disk utility would crash when opened (crash report below).
Also opening hwmond or emond from terminal resulted in this error:
Referenced from: /usr/sbin/hwmond
Reason: no suitable image found. Did find:
          /System/Library/PrivateFrameworks/PlatformHardwareManagement.framework/Ver sions/A/PlatformHardwareManagement: no matching architecture in universal wrapper
Trace/BPT trap: 5
The fix I found was to remove "/System/Library/PrivateFrameworks/PlatformHardwareManagement.framework" and restore a fresh copy from OSInstall.mpkg (found within the OS X installer) using Pacifist. I had to resort to this because re-applying the latest OS X combo update didn't fix it. Neither did resetting dyld cache or repair permissions. I'm not sure why the PlatformHardwareManagement framework broke.... But after replacing that framework Disk Utility is launching fine now. I thought I'd post this in case others are googing a similar error. Hope this helps!

As Doug has said, & indeed you have tried....you need to run diskutility from the OS install disk. Or more accurately, you need to run diskutility when booted from the install disk.
The following ( from diskutility help) should explain it clearly.
Start up your computer using another disk.
To use the Install Mac OS X disc, insert the disc and restart your computer holding down the Option key, then select the Install Mac OS X disc and click the arrow.
Open Disk Utility.
If you're using the Mac OS X Install disk, follow the onscreen instructions until the menu bar appears with the Utilities menu in it., and then choose Utilities > Open Disk Utility.
Select the startup disk in the list of disks and volumes, then click First Aid.
Check the S.M.A.R.T. Status at the bottom of the window. If you can't see it, be sure you selected the hard disk your volume is on, and not the volume itself.
If the S.M.A.R.T. Status is "About to Fail," back up your files on the disk as soon as possible and replace the disk.
If the S.M.A.R.T. Status is "Verified" or "Not supported," click Repair Disk to repair the disk.
If Disk Utility tells you to look for links to corrupt files in the DamagedFiles directory, two or more files occupy the same space on your hard disk and at least one of them is likely to be corrupt. Examine each affected file in the DamagedFiles folder, which at the top-level of the affected disk. If you can replace it or recreate the file, delete it. If it contains necessary information, open it and examine its data to make sure it has not been corrupted.
If Disk Utility reports "The underlying task reported failure," Disk Utility encountered a problem it could not repair. Back up as much of your data as possible, reformat your disk, reinstall Mac OS X, and restore your backed up data.

Help with 10.8.1 Disk Utility... doesn't work.

I Just bought a new macbook pro. It has ver 10.8.1. I get this when trying to open disk utility:
"You can’t open the application “Disk Utility” because it may be damaged or incomplete."
Normally, if the machine came with a disc, I could restore from the disc. But this one, no disc. Just a pretty pamphlet.

Or pack it back up in the box it came in, Take it back to the store you bought it from and get a full refund. Then buy another that works correctly right out of the box.

Crucial m4 256 GB internal SSD not showing in disk utility on MacBook Pro a1226 (late 2007) 2.4 ghz.

After the original Fujitsu 160gb hd died in my MacBook Pro (model A1226), I was advised at the Mac store to upgrade to a SSD. I installed the crucial m4 256gb internal SSD and powered on MacBook Pro from the Snow Leopard install disk so I could use disk utility to erase and reformat the new SSD.
The problem is the SSD is not showing up in disk utility. I have opened the computer twice and checked cable connections and still no luck. I have powered off computer and let sit for a while and tried again. I check compatability on crucial site before ordering SSD so I don't know what the problem is. Bad disk?

You were given bad advice.
Return/Sell the SSD and buy a 7,200 RPM hard drive instead, it should work fine and a more of a match for your older machine.
Your Mac doesn't have the faster SATA connections for a SSD also 10.6 isn't equipped for SSD's only hard drives, your basically putting a Ferrari engine in a Yugo, it can't handle it.
The 7,200 RPM drive will give you the performance and more drive space than a SSD anyway.
Follow these instructions when you erase and install 10.6, it will give the best results.

Problem with external harddrive and disk utility

I have just about ran out of room on my iMac G3 so I went to walmart and bought a FreeAgent 320 GB external hard drive. On the bottom it says its compatible with my iMac G3 you just have to format it using disk utility.
So I open up disk utility and I see my hard drive. I click on it and then go to erase so I can format it to work on my mac. However everything on the erase page of disk utility is greyed out and and I can't click on anything.
What do I do? Thanks.

I recall that the old imacs could not use a HD over 130G or so unless they are partitioned. So you may need to make three partitions first with your disk utilities. It should format it at the same time.

Mounting .dmg updates using Disk Utility?

Hello Apple Forum,
I've got a problem you might be able to solve.
Adobe Illustrator CS is crashing. I have posted the prob here and at the Adobe forum. The Adobe forum has advised me to install the 11.0.2. Illustrator update.
Can you tell me how to mount the .dmg file after downloading with Disk Utility? It's not just double click is it?

I concur with Alex that something is amiss with your system. Normally, double-clicking on a .dmg file will invoke DiskImageMounter which decompresses the .dmg image and puts a virtual drive on the Desktop, from which you can copy files or run an installer (this is what 'mounting' the .dmg disk image means). If you open a .dmg using Disk Utility, either via the 'Open Disk Image' command from Disk Utility's File menu of by control-clicking the .dmg file and selection Open With... to call up Disk Utility, you see a message window about "attaching disk image" while Disk Utility is mounting the mage.
That you're mounting a .dmg image, briefly seeing the mounted image on the Desktop, only to have the mounted image disappear, suggests you either have the Finder Preferences of the System Preferences> CDs&DVDs set to ignore the mounted hard drive images, or the sysytem prefernces are corrupted and think that's what they should be doing. Alex's suggestion on running Disk Utility> Repair Disk and Repair Permissions is the first step in troubleshooting the issue.
You can also check preferences by logging in to a different user account (if necessary, create a new, troubleshooting only account to work with a fresh set of default permissions and preferences) and seeing if that different account shows the same behavior; you can download and run Preferential Treatment; or launch Applications> Utilities> Terminal, then copy and paste the following exactly into Terminal and press return:
find ~/Library -name '*.plist' -exec /usr/bin/plutil -lint {} \;
The refernce to using ther Finder's Go menu was to look for the mounted disk image in the leftmost pane of the Finder window that opens; e.g., if I doble-click "gc593x.dmg", after a few seconds I'll see a hard drive icon "GraphicConverter" in the Finder window and also on the Desktop. If I click on the GraphicConverter hard drive icon in the Finder window, I see that mounted drive's contents. What happens when you click on the mounted drive's icon on your Mac?

Disk Utility fails to launch

disk utility just won't open in my new Leopard install (Archive & Install).
Any ideas. Just one bounce in the dock and that's it.
Also when I print anything, the printer shows in the dock then crashes. The doc still prints though.
Thanks
Matt

Hi, I'm having the same problem. Every time I launch Disk Utility it says that it 'quit unexpectedly'
I ran the unix executable in the terminal and the startup gave this output:
/Applications/Disk\ Utility.app/Contents/MacOS/Disk\ Utility ; exit;
hbt-leibundgut-m-02:~ fmeggers$ /Applications/Disk\ Utility.app/Contents/MacOS/Disk\ Utility ; exit;

Is this a permission problem in the /usr folder with this dylib file? I'll try to restart in Safe Mode as suggested now.
