Disk Utility hangs - found a solution

When I opened Disk Utility, it displayed "Gathering disk information..." but never got beyond that point. I have an external La Cie drive which I use for occasional backups, which was turned off a that point. When I turned it on and launched Disk Utility again it behaved normally. Not wanting to keep the external drive on all the time, or even turn it on when I want to use Disk Utility, I looked in the Disk Utility preferences and found under "Mounting", a checkbox that said "skip on remote volumes". I checked the box. I dismounted the external drive, turned it off, and tried Disk Utility again. Voila! It all worked. Maybe that's the solution for this problem in general.

Hi Donald, and a warm welcome to the forums!
Great tip, thanks... I never knew about that pref in all this time!
That doesn't exist in 10.5.8 it seems though.

Disk Utility Hangs during format

Yes, I've seen a hundred other posts on this but all have been archived with no solution.
It seems very likely there is a 10.4 problem. When I try to format a 160GB drive connected via USB Disk Utility hangs and never completes. I have tried to partition it as well with no luck.
Is there a fix? Is Apple working on the problem? Is there a workaround? Even a commandline fix would be acceptable.

This is ridiculous. I have tried 4 different physical drives in 4 different physical enclosures (3 different brands) and it still hangs Disk Utility.
I know I'm not the only one with this problem. What the **** is going on? I can't format a disk and therefore I can't use it. This is absolutely unacceptable.
Sometimes my machine hangs in such a way that I can't even reboot it, it requires a physical power down.
I have been forced to format these on a Windows machine with FAT32 (using a 3rd party app to get past the GB limitation MS sets). I don't want FAT32, I want HFS+. But I can find no other way to do this in Tiger as it ALWAYS hangs regardless of drive, enclosure, filesystem type, size, number of partitions, etc, etc.
Is OS X truly this bad that it can't even format a drive properly? Am I really going to have to rely on Windows and FAT32 whenever I want to format?

Disk Utility hangs attempting to erase SimpleTech 100gb external USB disk

I'm attempting to erase and format a SimpleTech 100gb external USB disk. Disk Utility hangs. The system error log says:
"AppleUSBEHCI[0x1d59000]::Found a transaction past the completion deadline on bus 91, timing out!
Jul 21 17:30:35 Kari-Hohnbaums-Computer-2 kernel[0]: USBF:"
The console log (and Disk Utility log) shows:
Preparing to erase : “PBEX1”
Creating Partition Map
error writing partition map: Device not configured (6)
Disk Erase failed with the error:
What is the problem? This disk is recognized by Tiger but only as read-only as it ships as an NTFS volume and must be erased and reformatted before it can be used by a MAC.
All help appreciated.

I tried the partition approach and it unfortunately failed as well. The same "hung" symptoms as before. The green light (disk activity) on the disk flashed several times at the initial request, but that was all. I eventually interrupted it after a hourn which generated the same system log message: AppleUSBEHCI[0x1d59000]::Found a transaction past the completion deadline on bus 91, timing out!
The disk utility log says:

I don't have easy access to a Window's box. I do have access to a Linux system. Perhaps I can configure it there and it will work on my PB.

Disk Warrior/Disk Utility Hangs with External HD

okay, so i will try to make this as quick as possible.
last year, i had an external hard drive that i had been saving all my audio work on. one day i had to restart (i was having a lot of problems with my then IBook G4) so i did, and the drive was no where to be found. made sure there was no connection problems (ie my USB ports) and everything seemed fine. let it sit for a while, thinking maybe it was just tired or something. tried again, same story, and it also made disk utility hang. tried it on a friends mac, same issue.
i also had a a lot of video/music that i watched with my xbox 360. i could still access those files with the xbox, which was weird.
so then my ibook eventually died, and here i am with a newer G5 quad. i tried it again, and still the disk utility hangs, and ive also tried Disk warrior 4. this also hangs.
also, i have tried switching the enclosure to no avail.
its not the end of the world if i cant get the data back, but i would REALLY like to.
any suggestions?

System Profiler shows the same thing: "Manufacturer: PI-236" for each of these HDs. I'm not sure how to rename these drives (I'm not talking about the partitions on them, which I've given descriptive names).
The strange thing is that on my MacBook Air (upgraded to Lion) one of these HDs (now connected via USB) shows up in Disk Utility as "Ext Hard Disk Media" instead of "PI-236". Still not a whole lot of information, you'll notice.
Another external HD (partitioned earlier under Snow Leopard) is shown correctly as "SAMSUNG HD501LJ Media" on both computers.

Disk utility hangs MAC G4?

Why does Disk Utility hang when starting? ~ Doug

Hi, Doug.
A little more detail on how you are launching Disk Utility on the stated "G4" would help. Some more details about the specific G4, and the problems that may have led to you attempting to run Disk Utility on it would also be useful.
Try running steps 1-2 of the Procedure specified in my "Resolving Disk, Permission, and Cache Corruption" FAQ.
Good luck!

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

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

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

Disk utility hangs during disk verify

Initially 'disk verify' registered errors on exit - minor error/issue it said,some kind of header problem, so I ran disk utility off the install disk. Now the machine's native version of disk utility hangs during disk verify, blue & white spirals forever.
This coincidentally straight after my gmail/google address/account was hacked a couple of days ago.

Have you tried booting in SafeBoot mode (shift key held on start
until login screen appears) then launch Disk Utility and then run
its 'repair disk permissions' item, selecting the Macintosh HD;
and then note the repair window. It should fix something.
And when Disk Utility is done, quit it, and restart the Mac normally.
{...It is unlikely something from gmail affected your computer unless
you open up unknown sourced emails or go to odd web sites where
something may be downloaded from there, which you would almost
have to install (as admin, etc) for malware to work. You can get and
try ClamXAV for free to see if it sees any malware virus content.}
If you use Gmail, and do not log in using the https:// (secure http)
you should change the habit and bookmark the secure login site.
And when booted from the Installer disk and running Disk Utility
from there, see about running "repair disk" and not verify. The
repair choice will verify; but verify will not repair. Could be if
you cannot use the Utility to Repair the issues, and the other
SafeBoot mode and the computer's Disk Utility to get it working
you may need to further troubleshoot and/or get third-party tools.
In any event...
Good luck & happy computing!

Disk Utility hangs up

Running a G5 IMac with 10.5.1. Tried to repair permissions and Disk Utility hangs up at about 25% of the way through the process. Ran Disk Warrior. Still hangs up. Started up form Leopard Install and tried to repair permissions. Still hangs up. Otherwise the system seems to be running OK. Any help or thoughts would be appreciated.

Disk Warrior is NOT compatible with Leopard at this time.
I would not use my Disk Warrior.
Permissions take from 10 to 30 minutes with 10.5.1
Give it time.
It seems like it just sits there on "Less than 1 minute" but it will eventually finish.
Again, give it time.

Disk Utility hangs when erasing external disk

In Time Machine I wasn't able to figure out how to attach an external drive via USB. I guessed that it probably wouldn't work on a MS-DOS filesystem, so I started Disk Utility, which I never have used before. I have formatted disks before on Linux and on Windows, so it's nice to see a great app for this.
In the Time Machine brief help text, there is not mentioned what kind of filesystem that is required or if it work with any filesystem. So I searched, and it seems as if HFS+ journaled case-insensitive is the filesystem that one should choose. Can anyone confirm this?
When I click erase then the Disk Utility program hangs and I see the spinning beachball. The Activity Monitor program shows that disk activity stops after a few seconds. There is no more activity, so after 5 minutes I stop the program.
I have tried several times, and I see the same behavior. I even tried restarting the computer. But no luck.
Now my external disk no longer shows that it's a MS-DOS filesystem, but shows that it's HFS+ journaled case-insensitive. Probably not ok so far. I try creating a single patition, with format: HFS+ journaled case-insensitive, without OS 9 drivers installed. When I click apply then spinning beachball again and diskactivity stops after a few seconds, and I stop the program after some minutes where it has been inactive.
My guess is that the disk-erasing task failed and has left the disk in a broken state. During this task Disk Utility began to hang for a reason that I don't know.
My second guess to why the create-partition task failed, is that the disk is in a broken state, and thus the partition cannot be created, and Disk Utility hangs.
How do I format the external disk from the command line?

In Disk Utility, select the drive mechanism (not the volume on it) and click the Partition button. Use the Options button to choose the GUID partition scheme, then make one HFS+ (Journaled) volume.
There is no point in using the command line for this task, because if Disk Utility cannot deal properly with the disk, Mac OS X will not either. Disk Utility is using diskutil to do the partitioning and formatting.

Disk Utility hanging on all user accounts

Hi,
I suspect that my son applied new permissions to enclosed items somewhere and that this is the reason that Disk Utility hangs (doesn't respond) when I start it. As a remedy I repaired permissions while started from an external disk and then applied some command lines that I learned for resetting user account permission (http://discussions.apple.com/thread.jspa?threadID=1655174&tstart=0). But still DU is unresponsive and must be force quit. Additionally I cannot open the DVD tray and Firefox tells me "...update available but you do not have the systems permissions required to install it....".
So I think my user permissions reset was not successful. My question is: did the command line language change from Leopard to SnowLeopard because Terminal gave me some feedback that "-H makes sense only with R" or something to that effect.
Do you have any idea about these things? What's the best way to proceed? Thanks.

Has command line language changed in SnowLeo compared to Leopard?
There are a few changes that reflect the differences between the two OS versions but the vast majority of commands are the same. There are hundreds of commands. Including the flags, switches, & options available for them there are thousands of variations. Plus, characters like spaces, slashes, dashes, & quote marks have special meaning depending on where they appear in the command line so even a minor typo can dramatically change a command into something other than what you want.
Because of this, you should not use a command unless it is specifically recommended for an issue you have explained completely or you have at least a fundamental understanding of command line syntax & the options for a command you are going to use. Each command has a manual page ("man page" for short) that you can access in Terminal by typing the word "man" followed by a space followed by the command name. For example, try "man man" to see the manual page explaining that command.
It would help greatly if you could provide the exact command & flags you used, plus any error messages they generated. Also, "standard procedures" doesn't tell us much since different users consider different things standard.
I suspect your problem is not caused by mis-set permissions, although they may have lead to the condition that caused it. But without more info it is hard to say what the problem is or how to fix it. It might be simplest just to reinstall the OS (which for Snow Leopard is not that big a deal), let Software Update bring it up to current versions, & then deal with any remaining user level permission issues separately.

Disk Utility hangs during DMG file creation

I use disk utility to create DMG files from folders (with the corresponding command from the File -> New menu). Every now and then (and quite often, really), Disk Utility will not complete this process, but instead hang forever. It seems that something in the kernel gets stuck, because the machine can get increasingly unresponsive after the hang has started (for instance, I wanted to look in the system log right now, but running less on /var/log/system.log would create long hangs on the whole UI). The only way out is a reboot.
The machine is otherwise very stable.
(Ah, and Time Machine started at the same time now, and doesn't seem to be able to run - maybe disk utility and time machine are creating some deadlock situation?)
Anyone who has seen similar behaviour?

I haven't had this issue this since upgrading to Snow Leopard, so I assume it has been fixed.

Disk Utility hangs

My drive is partitioned into 3 logical drives.
1 - boot and appliactions (Disk Utility repairs permissions OK)
2 - CD scratch disk - Disk Utility verifies the disk OK
3 - data - Disk utility displays Verifying Disk Data but then hangs with no activity. Error log says that D cannot be unmounted.

Sounds like there's some file that's being used on the third volume. Try this. Restart, launch Disk Utility, select that volume, and click on the unmount button. If that works, then select the volume, select File->Mount Volume, and repair the volume.

Disk utility hanging/ not responding.

so i've been having some drive issues recently. one of the manifestations of this is while trying to open Disk Utility to repair permissions, verify disk, etc. it hangs as soon as the superdrive makes it's noise. it's usually fixed by a restart, but invariably happens again. it's usually coupled by some other funkiness when accessing a disk internal or external (ex. reconnecting media in FCP or choosing system settings in FCP)
i have had slight quirks from the super drive. it wont read blank CDs or DVD-DL. DVDs and blank DVDs have been fine, CDs with media on them have been fine too.
as far as disk maintenance, i recently reformatted my startup disk and reinstalled SL and restored from a back up. have run disk warrior, repaired the disk from SL install disk and permission repairs.
any help appreciated

Disk Utility hanging on Erase/Partition OR Howto backup a dual boot Mactel?

I'm trying to use Disk Utility to format an external usb hd as HFS+ for backing up my Macbook. Running 10.4.7 and Disk Util 10.5.6 (latest version afaik)
Problem is whenever I try to either Erase format a hard drive using my usb2 external enclosure, Disk Util just kinda freaks, not really doing anything, and after a minute or so becomes the program becomes unresponsive. Luckily the rest of my system keeps on working, and I can just force quite disk util. But when I try to shutdown/restart my system I'm forced to do a hard power down.
I've tried leaving Disk Util running overnight, thinking it was just needing a little extra time to get thru the process, but nothing changed when I woke. And a gave the macbook a good hour to shutdown cleanly, but it stays stuck with the blue screen and the spinning gray wheel at the very end of teh shutdown cycle.
Looking at the disk util log (after force quiting and restarting the util) it will simply say:
Aug 12 03:24:09: Disk Utility started.
Preparing to erase : “Mb”
Creating Partition Map
Aug 12 03:25:50: Disk Utility started.
I've also tried running disk util off the osx install cd (tiger 10.4.6), but i get what seems to be identical behavior, and i have to manually turn off the macbook.
I've tried this with two hard drives with identical results. In Windows (boot camp) im able to format the partition fine, but it only does ntfs because of the drive's size (and I'm not trying to use a windows fs anyway).
I plugged the usb hd into a powerbook, and used a 10.4.0 retail cd to run disk util (no hd in the powerbook) and its able to erase/partition the disks just fine. I can then plug them back into the macbook and theyre recognized just fine. But its PPC system and doesnt offer for gtp partitioning which I'm thinking will be a problem because ultimately I'm trying to use this drive to do bootable backups of my macbook.
I'd like to figure out what is wrong with Disk Util. But even if i get the partitioning working, i have the larger problem of -how- to backup the macbook's hd onto an identical sized hd (80 gigs), that will make both osx and windows bootable backups that I can restore off of.
One thought was to use the unix utility dd, and just do a bitwise copy of one disk to another. Any idea if this would work?
Another option would be manually creating the partitions myself, and then backing up each of the drives seperately. Not sure if I could even make a bootable backup of windows from within osx.
I know I'm not the only one running boot camp and looking to have reliable backups. What are other people doing to address this issue.
Ideally I would like to find a solution that:
*creates an identical disk with two bootable partitions
*can be automated, or at best a few simple steps that can be done once and then walked away from

Can't format ssd... Disk Utility Hangs

Hi all!
Too long; didn't read: I need a way of formatting clean SSD for installing OS X, as the apple Disk Utility doesn't seem to be up to the task!?
A bit of background (UNRELEVANT for question, here to make thread useful to others when searching): A couple of days ago I upgraded my MacBook Pro mid 2010 from OS X 10.7 Lion to 10.9 Mavericks.
It's a standard 13" Macbook Pro mid 2010, cheap edition, except for the HDD to SSD upgrade (upgrade ordered while ordering computer, this it's an Apple SSD).
Suddenly yesterday my computer would not wake from sleep. I closed it by a long press on the power button, restarted it, it used a lot of time to show the Apple logo on white background along with the "working wheel" (around 10 or 15 minutes), then replaced the Apple logo with a "No Access"-logo.
While runnig a Disk Repair un Disk Utilities from a Lion Setup DVD fixed the startup issue in the first attempt, the the computer just froze when I logged in, and I choose to reinstall from scratch.
The SystemsRescueCD (small Linux with a lot of file-system support) proved very useful for making a backup of my data.
Attempts at formatting: The Apple Disk Utility (no matter if it's run from Lion DVD or Apple Internet Recovery) is extremely slow at formatting the SSD. Sometimes it will hang for 10 to 20 minutes, and it only completed the formatting once... kinda...
it took around 6 hours, but after trying to unmount the disk for 4 hours, I choose to kill the computer (and restart), as the partitioning step was complete. OS X could not be installed to the disk.
Since the Apple Disk Utility couldn't format the SSD, I tried formatting in GParted (using SystemsRescueCD) to HFS+ with Master Boot Record GPT (GUID Partitioning Table). It took around one second to complete.
When rebooting and starting the OS X installation, it did "see" the partition, but complained that the file system wasn't journaled. I used the Apple Disk Utility to enable journaling (it seemed to work!), but when I restarted the installation, it froze when it had to deal with the filesystem.
To check if the SSD was able to boot a operation system, I installed Linux Mint. Besides from the usual driver issues with Linux, it worked.
I really hope someone can help -- my Bs.C. thesis is due quite soon, and this computer crash couldn't happen at a worse time

Longtallsally28
I was thinking that same thing but it said it only applied to MacBook Airs.
Not so,...any and all SSD can fail.
#1) Why does the computer not recognize SSD partitions? (i.e. revert to Disk0s1)
A likely failed SSD
#2) Is there a possible component within the computer causing the continued failure? ( Is there a diagram showing all the components within the MBP?)
Yes, the SSD controller on the SSD module
#3) What do I have to do to make this computer work?
