Disk Utility not completing

Only since Mavericks has Disk Utility sometimes not completed (though it's probably simply just a display bug).
I'm not having a problem regarding my system.... it's just that sometimes the DU window doesn't show the completion for verification (only) of my boot partition. Normally it gives a line in green that says all is okay.... but sometimes this okay does not appear even though the progress bar has disappeared (i.e. the verification has probably completed since the bar is gone).
I did a search in this forum for any similar problem (prior to posting this), but couldn't find anything.
Anyone else seeing this?

You can run Disk Utility from Recovery with all features intact and accounted for.

Disk utility not completing, please help...

Hi everyone, I'm trying to erase an external drive I've had for a while. I formatted it once with no probs. I've hooked it all up via USB, gone to disk utility, clicked the volume, clicked erase, zero out all data, selected "journaled" from the drop down list, clicked erase. It get about 90% done, which takes about 2 hours (80gb drive) then just doesnt move and i have to force quit.
Any ideas?
Thanks
Phil

If that HD has a FireWire connection, try Disk Utility with that configuration.
If it doesn't have a FW connection, then you can try these steps. Unmount the ext HD, power it down, and disconnect it. Boot the computer with the install disk, select your language, and, when the menu bar pops up, select Utilities, and repair the disk and permissions. If you get a clean bill of health, then quit DU and select Utilities->Startup Disk->G5 boot volume and click Restart. Reinstall the 10.4.9 COMBO update, after restart, launch Disk Utility, and repair permissions. Shutdown the computer for at least 30 minutes. Restart it, hook up the ext HD, and give Disk Utility another whirl.
Another option is to get a FWHD. They're much faster and more reliable than USB.

Hi-
The last time I saw a similar problem to yours, he was also running Panther. I advised reinstalling the 10.3.9 combo update, and his woes were gone.

Another thought is to check System Preferences/CD's & DVD'S, and check your selection nuder "When you insert a blank CD" (or DVD).
Running Disk Utility from the install disk, and repairing permissions is also another possible fix.

OS X Disk Utility not recognizing Seagate 3TB drive in dock
Been scouring the webs and can't quite figure this one out.
I just purchased a Seagate 3TB drive intending on using it for Backup.
Ended up plugging it into a dock and couldn't get it to show up in Disk Utility..
Interesting enough, I plugged this into an HP laptop and it displays just fine.
Anyone know the solution?

How does Disk Utility estimate completion time?

I'm sending an external drive back to the vendor for troubleshooting, and want to make it more difficult for a curious tech to examine the data there. So I told Disk Utility to Zero Out Data and Erase Free Space. The drive was just initialized, so it's all free space. Did I mention it's a 2 TB FW800 drive?
Anyway, when I started this yesterday, the time estimate was 14 hours. (No hissing please.) Sleep is only enabled for the display: computer and HDs are set to "Never" sleep.
When I checked this afternoon (about 24 hours later) the estimate was "1 day, 5 hours."
How is this estimate calculated?
Thanks,
harv47

The estimate is based on how long it already took to do how many blocks, and how many blocks are left to do. If you told it to overwrite 35 times, it will be a long, long time before it completes.
The estimate is made grossly large by the presence of Bad Blocks that need to be Read during the test (not the case with Erase and Write Zeroes).
Each Block is written with some redundancy bits, so that small errors can be corrected on reading. A Bad Block causes the drive to re-read. and re-read, and re-read, in hopes of getting correctable data the next time. This should NOT be an issue in writing. But if the drive stops responding (which can and does happen with a bad drive) the Erase function will just sit there, thinking it is making progress, and stretching out the time.
Thanks, Grant.
If I read your reply correctly, Erase and Zero Out free space shouldn't elongate the process, because there's no read occurring.
The drive will not be Mounted while Disk Utility works on it, so it will not be on the Desktop. But ask Apple System Profiler \[ About this Mac > More Info > Serial ATA ] if the drive is still THERE . If it cannot be seen, you have your answer -- the drive dropped out of sight while being tested -- Bad Drive.
Well, now I am confused. It's a FW800 drive. It's on the Desktop. And it appears under FireWire in System Profiler. AND Disk Utility shows a mount point. But the Unmount and Eject buttons are grayed out.
Will the drive be mounted if it fails to respond to Disk Utility? That doesn't seem to make sense.
How do I determine its status? It appears to be stuck at "1 day, 5 hours" but it'll take an hour for that to change. I think it's been that long since I first noticed the time.

Disk Utility not finding Hard Drives after Updates

Howdy;
Updated my B&W G3 to 10.4.4 and itunes 6.0.2. After update and restart, ran Disk Utility (DU), which seem to just get into a loop "Gathering disk data". Force quit DU and tried running from Tiger DVD, but similar story.
I have done a little research and there has been many problems with DU linked to itunes 6.0.2 update, but not quite the same (no B&W G3 w/10.4.4 and different DU hang point).
I followed: http://discussions.apple.com/message.jspa?messageID=1505537#1505537
and even tried moving iTunes to desktop; trashing several iTunes.pkg files; restarting, all to no avail.
Any additional suggestions out there?

I doubt that any jumpers are needed, since this is the only (master) drive in the system. WD's site has pretty good info on this. Verify for yourself however.
Also, from their site:
How to partition and format an internal slave drive or an external drive in a Mac OS X (all versions).
Answer
In Mac OS X, you can use the built in Disk Utility to partition and initialize the drive so it will appear on the desktop.
1. Open the main drive (the drive that contains the operating system).
2. Open the Applications folder.
3. Open the Utilities folder.
4. Select Disk Utility.
5. The drives are displayed on the left side of the window. Click on the drive that you wish to partition (the top drive listing for the hard drive that you want to work with).
6. Once the drive is selected click on Partition.
7. Click on the Options button to select the partitioning scheme.
8. Click on Apple Partitioning Scheme or Apple Partitioning Map and then click on the OK button.
9. You will see several options for setting up the drive. Once you have selected the number of partitions, the format type you want, and a volume label, click the Partition button.
10. Following the completion of this process, the drive will appear on the desktop.

As long as the report ends up with 'Permissions repair complete' then, as far as permissions go, you are fine. You can ignore the various statements in the report:
Permissions you can ignore on 10.5 onwards:

Using 'should be -rw-r--r-- , they are lrw-r--r--' as an example, you will see the that the permissions are not changed, but the | indicates a different location. This is because an update to Leopard onwards changed the location of a number of system components.

Disk Utility Not Repair Permissions on OS 10.4- Are there other options?

How can I repair repair HD permissions when disk utility does not work? I have a powerpc g4 that I installed a second internal HD and then system would not boot up. Evidently the second drive was damaged and as a result something affected my boot on my main drive. I removed the 2nd hard drive, reset pram, nvram, and would not boot. Tried the usual reset commands and no boot up. (gets to the gray block screen instructing to restart and stops). Restarted trying to get to safe mode by holding down "shift" key but only gets to blue screen and goes no further with spinning circle looking for something. Used my os x install disk and tried disk utility and s.m.a.r.t indicated was ok and ran repair disk and passed with no problems with the file structure. Then ran disk permissions and disk utility would not run or would not complete. I left the computer on overnight to see if it would repair the permissions. Then I went ahead and reinstalled os x 4 again on the HD drive using the save last boot option and restarted and the computer booted up. The desktop came up looking like the old one but most items would not work properly and very slow or would close automaticly. Looked in system information and found spaces between items. I closed the computer down by restart again to see if it would correct the problem but went back to gray screen instructing a reboot. Reboots brought me back to the same gray screen. Is this drive now not usable, can be zeroed out and resued, or just replaced? Where do I go from here....thanks

I installed a second internal HD and then system would not boot up. Evidently the second drive was damaged
What makes you think this? It's not very often that a new hard drive is defective out of the box. More likely is that it was connected improperly. Don't jump to conclusions without evidence.
Then I went ahead and reinstalled os x 4 again on the HD drive using the save last boot option
What? No such thing. Do you mean Archive & Install?
Is this drive now not usable, can be zeroed out and resued, or just replaced?
If Disk Utility says the drive is good, then we have to assume that's true. It appears that you've somehow corrupted your entire OS X installation, so whether or not you have a backup from before this happened, your best option now is to completely erase that hard drive and reinstall OS X from scratch, along with all the Software Updates to bring it to 10.4.11, as well as your third-party applications.
Then, if that doesn't work, that may be an indication of a drive problem, or even a system hardware problem.
To prevent this kind of thing from happening again, you need to invest in at least one external backup drive to use for a bootable backup of your entire hard disk, and keep it updated every day before you shut down your Mac. You can use SuperDuper ($27.95) or Carbon Copy Cloner (donationware) for those.

Time Capsule hangs at end of full backup, Disk Utility "not responding"

I'm running a Mid 2011 iMac 27" with OSX 10.8.4 and using a WiFi connected 3TB Time Capsule (4th Gen).
I've noticed that the Time Capsule seems to get stuck at the end of a full back-up (let's say 260 GB of 260 GB) and won't end, even after hours of being left alone.
When I mount the Time Capsule Sparse Disk Image Bundle and then try to run Disk Utility, Disk Utility is shown as "Gathering Information," but the Finder and Activity Monitor list Disk Utility as "not responding." (No disk information is shown in Disk Utility.) This happens both when I connect via WiFi to the Time Capsule and when I connect directly using an Ethernet cable. If I don't mount the Sparse Disk Image Bundle, Disk Utility works fine, immediately showing my iMac's Hard Drive, so it only happens when the Time Capsule Sparse Disk Image Bundle is mounted.
1. Is Disk Utility truly "not responding" or is it just taking forever to load because of the 3TB hard drive?
2. If it truly isn't responding, what can I do to see if the TC needs to be "repaired"?
3. What's going on with my TC that it hangs up at the end of a full backup?
Thanks.

That's one of the causes of a deep traversal. The UUID (Universally Unique IDentifier, the long string of numbers and letters) for the Event Store on your internal HD doesn't match the one in TM's records from the previous backup, so it must do a deep traversal instead, comparing everything on your Mac to the latest (completed) backup.

Trouble talking to a disk. The first two probably involve the TC, the third one definitely does -- it's trying to create the new Event Store.

Most of that is also out of my area, but doesn't seem related to the TC or backups.
Hard to tell so far, but it looks like problem is on your network, or power, or with the TC. Trying backups to a directly-connected external HD would be a quick way to confirm that, and especially if these are your only backups, a wise thing to do anyhow.
It's always prudent to keep "secondary" backups, more so if your main ones are on a network, and especially if there's the slightest doubt about them. See Time Machine - Frequently Asked Question #27 for more info and some suggestions.
And/or, start through the list in the green box in #D2 of Time Machine - Troubleshooting.

Possible Workaround - AirPort Extreme Disk Utility not working in Windows

1) The only way I have managed to get Windows (in my case Vista) working with AE Disk Utility is to set it up using the "Assist Me" or "Manual Setup" with the Airport Utility with no special settings used to configure it.
2) Update the Station & let it restart.
3) On your Windows PC - Simply temporarily DISABLE your firewall until the next step is successfully completed. (I am using Norton 360).
4) Use the Airport Disk Utility to log on as either a Guest or User. (You should see the drive appear under Windows Explorer & see ALL the files it contains)
5) Re-enable the Firewall you have.
6) This works for me everytime & I am able to stay connected to my USB drive for as long as I want or I wish to disconnect it.
7) Repeat the above everytime you want to re-connect the drive to the Airport Extreme.
I am able to connect successfully using my MAC Mini & my Dell Laptop at the same time without conflict.
I know this is not an elegant solution, but until Apple get sort this out, it is failry easy to try.
I hope it works for you !
Enjoy :))
Mac Mini / PC Laptop Mac OS X (10.4.9) Windows Vista Ultimate

Well I fixed this. Get the AirPortBaseStationUpdate2007001.dmg update. I had installed this, but it didn't put in a few items that it should have. Mainly a little application in Core Servies. I used Pacifist to install the Airport Disk Utility again, and then restarted. I no longer got a beep when opening AD Utility, but I had to uncheck "Automatically discover disks" then turn off file sharing on the router, wait for it to restart, then turn file sharing back on, and then open AD Utility after restart and click Auto Discover. It then saw my disks. I also changed the name of the Windows Workgroup, I don't know if that had something to do with it. Good luck!

Repair permissions with disk utility not showing details

I've recently upgraded from Lion OSX 10.7.5 directly to Mountain Lion OSX 10.8.3.
1. Now, every time I use the Disk Utility to repair permissions, the details of the repair are missing. Not that I really need to see the repairs but the information confirmed that something was done. Now I see only what appears on the attached screen shot at the end of the repair.
When I had OSX 10.7, I always saw which files were repaired.
2. Also, the estimated time for repair is off. Under Mountain Lion OSX 10.8.3, the estimate says a fixed "1 minute" and remains so until finished. I just time the repair at 3.5 minutes and the estimate remained at 1 minute.
Under OSX 10.7 the repair time estimate would begin at 23 minutes or so then quickly work itself down in minutes until the repair was completed.
Can anyone tell me what's going with my iMac (27-inch Mid 2011), Mac OS X (10.8.3).

James --
Over the years, the function or understanding of Repair Permissions has changed drastically. When I first came here in 2004, lots of people thought RP was the "be all, and end all" of all Mac problems. (Myself included.) It was right up there with "take two aspirins, and call me in the morning." kind of response.
In fact, the notations you see are not in fact "errors." They're notations. And if you run them all day, you will almost always see the same ones over and over.
Every once in a while, if you experiences really wonky problems that seem unexplanable, the option to RP makes sense. Especially after a huge major application installation, especially Adobe apps
RP is not like a regular maintenance procedure. So, if you're not expelriencing very significant problems with your Mac, repairing permissions is probably not a good use of your time.

Copy of a CD (created by Disk Utility) not recognized by Windows or Linux

I created a copy of AutoCAD 2005 (not pirating it... just wanted a backup copy of the install CD).
I used Disk Utility (File > New > Disk Image From Folder) to successfully create a DMG file on my MacBook. I could mount the DMG and browse all the files on it.
I then burned a CD (Disk Utility > select DMG > click burn), which mounts fine on OSX. However, my Windows and Linux boxes will not recognize it (while they recognize the original CD just fine).
I tried again, this time setting the file format to DVD/CD master. It made a CDR file, which I burned to CD. Got the same result: Windows and Linux don't recognize it while OSX does.
So instead I burned the files to a CD ala drag and drop using Finder. This time the CD was recognized by Windows and I used it to install AutoCAD.
However, my understanding is that doing it this way won't work for a bootable CD, so I'd like to figure out why Disk Utility wasn't able to make an exact copy.
Any thoughts? Problem with copy protection? Problem with the CD's file system?

Yeah OS X's Disk Utility doesn't burn using the ISO 9660 file system while Finder does (I could swear I made a copy of an MS Office CD with Disk Utility, but maybe I'm remembering wrong). Anyway, Disco (a program I got in a MacHeist bundle) will make an exact copy of CDs. Anyone looking for a free solution, check out LiquidCD and burn, which may have the ability to copy Windows CDs (appears to be on their lists of features, but I haven't tried them myself).

'No' symbol on start-up, disk utility not recognizing internal drive

Need a little assistance.
Two days ago I was using the Macbook and it froze. Restarted and I was hit with the international no symbol. I've also gotten the blinking file folder at times when I've tried the holding down of various buttons on start-up.
I put a Hitachi 750 gb harddrive in last fall, it has been working fine up until now.
I do not have the system disk for Snow Leopard on hand, so until I can get it from my Dad, I decided to check on the system disk I actually have from the laptop purchase in 2007.
This allowed me to get to the start-up disk and disk utility area. I could not find my external harddrive in the list for a start-up, and it is the back-up using Time Machine. I also could not get the internal harddrive to be found in the utility so I could do a repair. It did seem to recognize that there is a drive, but not the actual named portion of it that contains the info.
I removed the internal and put it in an external case: my netbook recognizes that there is hardware, but does not let me access it. I attribute this to the fact that the drive is formatted for Mac and the Windows machine can't recognize the data.
My next step was to see if my old iMac would recognize the internal as an external, but since I don't know where the keyboard is and it is running an early version of OS X, figured it won't do me much good.
What is my next step? Will the Snow Leopard disk make a difference? Or is the reaction with the older system disk going to carry on the same way with Snow Leopard?
I was going to buy a Macbook Pro, but not for over another month, so I'm hoping I can figure something out with this and make it last a little longer.

I hooked my internal as an external up to my Mom's Macbook Pro and it recognized my HD. I'm thinking it is something internal with the hook-up, which is awesome, because maybe I can actually fix it!!!! Any thoughts?

Photo CD created by Disk Utility not seen by Windows

With my Disk Utility, I created a photo CD (appendable) - common .jpg, nothing special. When my daughter tried to print the pics with Windows, her PC said that the disk was blank.
