Network Installer: Can't run Disk Utility

Hi, all.
Just created a net install image. SIU's log did not report anything out of the ordinary, however for some reason I can't run Disk Utility, and I need to as the automated installation options frequently don't work.
I select Disk Utility from the Utilities menu and nothing happens.
I run the Terminal and try hdiutil and get
dyld: Library not loaded: /usr/lib/libbz2.1.0.dylib
Referenced from: /System/Library/PrivateFrameworks/DiskImages.framework/Versions/A/DiskImages
Reason: image not found
Trace/BPT Trap
Now, if we mount that image on a running Mac we can see the following
bash$ ls -l /usr/lib/libbz*
-rwxr-xr-x 1 root wheel 138436 Nov 1 11:33 /usr/lib/libbz2.1.0.2.dylib
-rwxr-xr-x 1 root wheel 138444 Mar 4 10:19 /usr/lib/libbz2.1.0.3.dylib
lrwxr-xr-x 1 root wheel 18 Nov 29 14:50 /usr/lib/libbz2.1.0.dylib -> libbz2.1.0.3.dylib
lrwxr-xr-x 1 root wheel 18 Nov 29 14:50 /usr/lib/libbz2.dylib -> libbz2.1.0.3.dylib
If we run the same command on the netbooted machine
bash# ls -l /usr/lib/libbz*
-rwxr-xr-x 1 root wheel 138436 Nov 1 11:33 /usr/lib/libbz2.1.0.2.dylib
lrwxr-xr-x 1 root wheel 18 Nov 29 14:50 /usr/lib/libbz2.1.0.dylib -> libbz2.1.0.3.dylib
lrwxr-xr-x 1 root wheel 18 Nov 29 14:50 /usr/lib/libbz2.dylib -> libbz2.1.0.3.dylib
So it looks like libbz2.1.0.dylib is symlink'd to libbz2.1.0.3.dylib, except libbz2.1.0.3.dylib doesn't exist in the netbooted image. But it does exist in the image when it isn't netbooted! Yes, they are the same image!
I also have two "Help" menus, just for kicks.
Does anybody know what's going on? I guess I'll re-create the image, but it'd be nice to understand what's going on and know if it's something I can somehow avoid in the future.
On the lighter side, this is the first time in nearly a year I haven't had to manually insert the CoreVideo.framework to get the image to boot!

Ah, forget what I said about it being the same image. I didn't notice that my chroot hadn't worked when I was checking... I was checking the live system instead. Good thing, too, 'cause that was just TOO weird.
Still doesn't explain why there's a link to a non-existent file. To test I created a symlink for libbz2.1.0.3.dylib which just points at the previous version. Guess what: Disk Utility works now.
I'm re-creating the image anyway and we'll see if the problem exists on that one as well. If it does, I won't be pleased. That'll be two repeatable bugs that break the NetInstall function for me in a year. Not cool.
Anybody else getting weird output if they type hdiutil in to Terminal at the Network Installer? Or do you have a non-working Disk Utility?

Can't run disk utility on Time Capsule

I hope someone can help. First, my time machine stoppped backing up to my time capsule about a month ago. After some research it appeared that the thing to do was use disk utility to repair it. I got a message "Disk Utility stopped repairing "Time Machine Backups" can't unmount disk. I tried to run Verify permissions and got this message "Warning: SUID file "System/Library/CoreServices/RemoteManagement/ARDAgent.apps/Contents/MacOS/ARDA gent" has been modified and will not be repaired.
Huh? Can anyone help me get back on track? Sally

You an also ignore the SUID warnings per Apple document.

Can one PPC Mac run Disk Utility for another's HD?

I have a PPC PowerBook that needs help. The Admin users are getting corrupted for some reason. I can still use other Users in Safe Mode.
I have another good PPC G3 desktop. Both running 10.5.8.
I can mount the bad HD on the good Mac's desktop but I can't run Disk Utility for it.
I've mounted with Ethernet and USB. Do I need Firewire? Do I need do try to use Target Mode?
Basically, I'm trying to use the good Mac as a startup disk for the bad one, I think.
Easy way? Thanks! JP
ps: My hunch is Firewire. I don't have any so I'm going to buy a cable soon. Unless someone here stops me! : )

Yes, you need Target Mode Firewire on both, a FW cable, then Disk Utility should be fine from one to the other.
Target mode...
http://support.apple.com/kb/HT1661
Sometimes Laptops need to have the FW cable unplugged & replugged after they'e in t mode to have it finally show up.

15in Macbook Pro early 2011 won't shutoff nor can I run disk utilities. Any suggestions?

Situation:
I have a 15in Macbook Pro early 2011 that I can not shutdown nor can I run disk utility to repair any issues. I recently had it serviced to replace a failing hard drive.
Known issues:
     - Disk Utility: Will not respond. A couple days ago I had to run it to repair some damage to harddrive. When I try to open it, it is frozen with the rainbow ball.
     - Shutdown: I can not shutdown or restart my computer as it freezes during shutdown with grey screen. I can manually turn it on and off by holding down the      power button.
     - Disc Drive: This may not be related but I can not eject DVD in the disc drive.
Any thoughts or advice would be greatly appreciated. I currently live overseas (for school) so just going to an Apple store is not really a realistic option for me at this time. Thanks

Take it back to where you had it serviced, there is usually a ~90 day guarantee
you can force a shutdown by holding the power button for longer than usual.

Raided xserve raid boot volume, OK to run disk utility?

I have been asked to assist another site in our organization, and they have an older g5 xserve and xserve raid. They have the xserve booting off a raided boot volume on the xserve raid (2 drives in a raid 1 config)
They have started having some issues, so I thought I would check the obvious stuff first (i.e. disk util > repair drives)....Just wanted to check here first and make sure that I can SAFELY run disk util on a raided boot volume that is hosted on the xserve raid...
also, does anyone know if diskwarrior will also work in this config? (again, safety being an issue)
Thanks in advance...

Yes, you can run Disk Utility to check the disk, or Disk Warrior or TechTool Pro and any other tool that checks the HD.
That is the point of RAID, it changes nothing of what an OS understands of a HD. If there are any problems and the drive/data is somehow 'lost' it is not due to RAID.
Safety would expect that you ahve a backup of this drive already, so running a disk check would only enhance and not reduce your safety by confirming reliability.

Cannot run Disk Utility, use terminal, or boot from CD, all HDs locked

I have a Mac Pro with 4 internal drives and 3 of them suddenly locked themselves. I can't run Disk Utility -- I get "underlying task reported failure on exit."
I can't boot from Disk Warrior CD. I hold down the C key til the Apple logo appears, and then the computer just restarts into my regular system on my hard drive.
I can run some apps from my startup drive, (obviously I can get on the internet). I downloaded Drive Genius but it will not install.
I cannot use the terminal to try any of those fancy tricks I read about here.
Here's what I get when I try Terminal:
login: PAM Error (line 396): System error
login: Could not determine audit condition
[Process completed]
And after that, I cannot type in the Terminal window.
Man, this is crazy. 2 of my other internal drives have backup systems on them, but they will not show up as choices in the startup disk section of my system preferences - cuz they are locked.
Any suggestions? I'm about to install a new drive and try and clone my working system on it and put Disk Warrior on it.

Wait, can I use Terminal from another computer in target mode?
yes, but do you mean you can boot it in target mode but not from a DVD? this is very strange. try booting fro a DVD in a different way. reboot and hold "option" at the chime. this should boot you into startup disk manager. normally you can insert the DVd at the point and choose to boot from it.

Can't get disk utility to work with leopard - iBook running super slow

I have an iBook G4 and it's running ssuuppeerr slow but I can't get disk utility to come up after I press C down. I don't know if I'm pressing it at the wrong time but I restart with the C pressed and it gets to the apple screen and it won't go anywhere else. It will restart normally but not with the C key. I've been trying for an hour and I can't get it to get to disk utility!
Any help is greatly appreciated!
Thanks

Welcome to Apple Discussions!
Do you want Disk Utility on your iBook or do you want Disk Utility on your install disc?
For Disk Utility on your iBook, go to Finder>Applications>Utilities and look in the Utilities folder. You will find Disk Utility there, and drag it to your dock where it will be handy to have it.
For Disk Utility on your install disc, insert the install disc and then restart and hold down "C" as you boot up so that you will boot from the install disc. Then choose your language, and then look for Disk Utility in the menu bar--I don't remember if it says "Utilities" or "Disk Utility". If you need to repair your startup disk (i.e. your internal hard drive), you would boot up from the install disc to do this.
However, I am wondering if you have enough RAM to run Leopard. You will get a big boost in performance if you max out your RAM. Leopard will run best if you can put a 1 GB RAM stick in your RAM slot.
If you want to repair permissions after installing and updating Leopard, you can do this with Disk Utility on your iBook. Repair permissions until there is nothing left to repair.
If you have more questions, please post back. Also, which ibook G4 do you have?
Good luck!

In the far left hand column, Devices keeps disappearing. I can get it back by downloading iTunes again but disappears again after I run disk utility.

With a Device plugged in - place your mouse cursor over DEVICES - you should see 'show' or 'hide'. Click on 'show'.

I think I goofed when running disk utility, and unmounted at the end and restarted. Now I can't get the disk to mount. What am I missing?

Which disk won't mount? What version of OS X? Your post is impossible to answer with no useful information.

HT203176 i have a slow macbook, i ran live disk utilities and said I need to repair disk from a cd. did that, I got volume repaired from the external disk. when I reboot from hdd, then run disk utility, I get the same error message i did b4 repair

i have a slow macbook, i ran live disk utilities (from hard drive), turned out I needed to repair disk from a installation disk. Did that, I got the volume (Hard drive) repaired from the installation disk disk. To this point, great!
When I reboot from hdd, then run disk utility, I get the same error message i did b4 repair. I went thru two rounds of this.....
Can anyone help? thanks

Sorry guys, I don't see how to reply to you so I use reply to "me" basically.
So the error I get is "volume header needs minor repair" and then you need to perform repair from the installation disk message.
I did repair not verify from the disk twice. Every time ending in the "the volume had ha been successfully repaired". Then I reboot from the internal disk. Run disk utilities from it, do verify and get the same error message I got before repair. I hope this can shed some light fr you guys. Sorry I didn't include details in the original

Unable to reload os or Run Disk utility off osx dvd

Late 2007 Macbook Pro ( 2.53 , 4gb Ram, 320 GB hd) Will Load into osx but has the grey status bar at every boot ( Approximate 10 Mins for full boot) Ran disk utility in osx found issues and says run off DVD to repair the disk. Ran disk utility off the original DVD that came with the mac, wont find the hard drive to run disk utility. try to reinstall the OS. The installer wont find the hard drive? any idea how to resolve the issue so I can re install the OS to remove the grey status bar.

I can make a partition on the HD.
You'll have to decide which works best for you:
-boot from install disc, partition the external HD, install OS X on it, boot from it and see if HD shows up there so you can try to repair it (make sure you don't wipe out your TM data; your internal HD may not be reliable).
-get DiskWarrior or TechTool Pro or another disk repair utility and see what it can repair (note that these are more expensive than a new HD, but can come in handy to have around).
-get one of the SMART utilities that supposedly tell you more about your HD (I'm not a fan of either of the ones I've seen/tried and am far from confident in their results).
-get a new HD and try restoring from your TM backup.
-get an external enclosure (15 bucks or so for a USB model from newegg, amazon, macsales and others).

Running Disk Utility off External Hard drive

To run "repair disk" in disk utility on my internal hard drive I'm supposed to insert my Install DVD, restart my mac and run disk utility - however running this program off the disk is much slower than running it off my 800firewire external hard drive. I've tried a few different ways of going about this:
1) Partitioning my hard drive in two (both HFS+) with more than enough room for the DVD, I've tried both making a Disk Image of the Install DVD and dragging it into the source field in the "restore" tab and dragged my Install partition into the destination field, after that was complete, I restarted my computer while holding the "alt" key I wasn't even offered the option to boot to my external hard drive
2) I've also tried after partitioning the external drive, in the restore tab just dragging the Install DVD (not the disk image) from the left of the disk utility window into the "source field" and again the partition into the destination field, and when restarting both with the "alt" key and by going to system preferences -> start up disk and choosing my external drive to boot from, I was still unable to boot off my drive.
Please let me know if anyone has any suggestions! This would be such a big help for me since I'm constantly helping people with diagnostic issues with their macs and this would save me so much time. Thanks in advance

I'm not sure why you can't make a bootable copy of the installer DVD using Disk Utility but as Niel suggests, it is much better to install the OS on a partition on the external drive using the DVD & then use that instead of a 'clone' of the DVD as a boot source to run utilities. There are several reasons for this:
1. You can update the installed version of the OS on the external to take advantage of any improvements, including to Disk Utility, that may be released in the future.
2. The version of Snow Leopard that runs from the DVD is a special one that among other things is optimized for read-only media. For instance, it doesn't write log files to the startup disk since it doesn't expect that to be possible.
3. You can include other utilities on the external & easily customize it to your liking. For instance, configure it for automatic login to an admin user account, drop Disk Utility into that account's login items & it will automatically launch at the end of the boot process. You can do the same with shell scripts or Applescript applications for just about as much automation as your scripting skills & imagination can dream up.
However, one thing to keep in mind: since a HD is not read-only but a DVD is, you can never be as certain that your external is as reliable as the DVD, since it is possible for something to change or corrupt files on the HD but short of physical damage the DVD is immutable.

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.

[10.3] Is it necessary to run Disk Utility as a preventive measure

I have here a small Mac environment of about 50 Mac's all running 10.3.9
A certain user now says that I should run Disk Utility regularly on all machine's since it gives a performance boost and fixes errors.
I think that as long as a user doesn't display any weird errors, the disk utility should stay where it is.
Does anybody have any good or bad experiences with this?

Hi Guru Evi,
The only two things that are required for a healthy Mac OS X are:
- Backup
- Enough free hard drive space on the boot volume (at least 10 or 15%)
Then some further precaution, safe, quick and easy:
- Run Disk Utility (from the Utilities folder) "Repair Permissions" feature, after using an Apple installer or Software Update.
- Manually run the nightly automatic maintenance: Once a month, open Terminal and paste this command:
sudo periodic daily weekly monthly
If you have more time, another safe and good precaution:
- Before any important software update, upgrade or reinstallation, or say twice a year,
run Disk Utility (from the Mac OS X install DVD or CD) "Repair Disk" feature.
Rerun it if errors found, again and again until it finds all was clear.
Good or bad experiences:
Using Disk Utility is completely harmless, you can do it as often as you wish (although it would be just useless of course).
Good luck!
