Disk Utility not transferring ACL info during restore

I'm having internal drive problems on a MacBook Pro laptop - had to boot from another USB disk where I used Disk Utility (DU from here on) on OS X 10.5.4, to create a backup of internal disk onto a newly created "sparse" volume located on a different drive than than the original, and when I looked closely at the two there were some differences with them. When I did a "ls -l" to look at both the new copy and the original, there was no ACL info - ie there was no "+", but on the original there was. Very few of the folders/files had a "+" but it seems puzzling that this information did not get transferred to what I thought was a clone of the original.
For example here are a couple of entries from the output of a "ls -laR" on the original:
drwxrwxr-x+ 204 root admin 6936 Aug 18 12:40 Applications
drwxr-xr-x 3 root admin 102 Mar 17 2009 Documents
drwxrwxr-t+ 70 root admin 2380 Aug 17 09:35 Library
and here are the same things in the new image copy:
drwxrwxr-x 204 root admin 6936 Aug 18 12:40 Applications
drwxr-xr-x 3 root admin 102 Mar 17 2009 Documents
drwxrwxr-t 70 root admin 2380 Aug 17 09:35 Library
So notice neither the Applications nor the Library folders have the "+" in the new version. Both these listings are portions of the top level of each volume.
Doesn't DU copy this ACL info when "restore"ing to the backup copy? What other info doesn't get copied when DU does a "restore" to create a copy? Is there a way to make an exact "clone" of a volume using DU or some other OS X utility?
Is there some way to tell DU to copy all this special ACL info?
Thanks...
-Bob

Don't know. However, Carbon Copy Cloner preserves ACLs.

I have an external hard drive from my time capsule that stopped working on me. I am attempting to access the data with a hard drive reader on my MAC. I am able to see the drive in disk utility and under system info USB. But I am unable to access the data.

I have an external hard drive from my time capsule that stopped working on me. I am attempting to access the data with a hard drive reader on my MAC. I am able to see the drive in disk utility and under system info USB. But I am unable to access the data and it does not show on the desktop when connected.

Ok if disk utility was able to verify the drive I doubt there is any problem.. are you trying to open a TM backup??
You need to mount the sparsebundle then check the actual info inside the bundle.
Don't use disk warrior.. if the disk has verified then unless you deliberately deleted files there is nothing that is going to do.
Pondini has a lot of stuff about getting access to the sparsebundle.

But if you have copied info to the TC that is now gone.. and the disk is ok.. I am not sure.. the TC will not have deleted the files itself.

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.

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?

Disk Utility not showing same disk space as get info on HD

Hi,
My Macbook Pro was really slow and i did Repair Disk and it seems to work much better. the problem is that when i get info on my HD it shows me that there is 200 GB free but when i go to Disk Utility it only shows me that there is 73 GB free???
How can this be?
Please help. thanks

OmniDiskSweeper is a free utility that checks HD space.

My Bootcamp partition will not boot. It won't mount either. It shows up grey in Disk Utility and cannot be mounted or restored.

It appears some sort of hybrid GPT MBR error. It was the resut of of partition editing. I have programs installed that were liscensed through a robotics program. I would not like to format it. I would like to atleast be able to mount it, and hopefuly boot it.
I looked at this but don't quite understand it.
http://apple.stackexchange.com/questions/59118/how-can-i-mount-partition-disk0s4 -that-became-inaccessible-after-a-clean-install

Hello bechardj,
I would use the disk utility to verify and/or if needed repair the partition to help troubleshoot the issue
From the help menu item: https://help.apple.com/diskutility/mac/10.8/help/index.html
You can check a disk for problems without repairing it. If you used the disk to start up your Mac, verifying means that you don’t need to restart your computer unless you need to repair your disk.
As Disk Utility checks a disk for problems, your computer may become slow or unresponsive.
Open Disk Utility from Applications.
Select a disk or partition and then click First Aid.If you run First Aid on a disk, Disk Utility checks the partition maps on the disk and performs some additional diskwide checks. If you run First Aid on a partition, Disk Utility verifies the all the contents of that partition.
If Disk Utility tells you the disk or partition is about to fail, back it up and replace it. You can’t repair it.
Click Verify Disk. If Disk Utility reports that it appears to be OK, you’re done. Otherwise, you need to repair it Repair a disk.
All the very best,
Sterling

External hard drive error / disk utility not repairing

I am having problems with a particular external hard drive. Device is a Transcend StoreJet 25M (640GB) currently formatted in Mac OS Extended (Journaled). It was previously formatted in FAT32, exFat, and also Mac OS Extended (Journaled). It started giving me problems when I used it to store all my music on it. My iTunes library and music files were all stored on it, and at one point iTunes started acting funny - it would play a song for a few seconds, pause, play for a further few seconds, pause again, and so forth. I decided to stop using it and when I shifted the iTunes library to the Mac internal hard drive and the music file into another external hard drive, iTunes worked fine. So I figured it must be a problem with the external hard drive itself.
I recently reformatted it to Mac OS Extended (Journaled) and transfered some data on to it (include a back up of the music folder). I noticed that Spotlight keeps trying to index the drive but never actually managed. Times indicated for indexing runs into days. The hard drive tends to be slow to load files expecially when there are multiple folders and tiers, and is generally unreliable. It occasionally unmounts, or when I try to unmount it I get an error saying it cannot unmount because it is being used (but no indication as to which app is using it even if all apps are closed except for Finder).
I tried repairing it using disk utility. The attached image shows the results. It seems that it can't be repaired by disk utility. At this point, and after much deliberation, I would have to questions:
1. Should I just smash the thing on the floor?
2. Is there another application I could try and repair it with?
3. Even though I have reformatted it several times, it keeps giving me the same problem. When I do a disk verification of the hard rive itself it all seems fine, however when I do a disk verification or repair of the volume I get the error shown in the image. Is this a problem being caused during formatting?
Any help would be much appreciated.

Oh, I forgot to attach image....

'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?

DisK Utility Not Repairing Permissions

Hello, I have a problem with my iMac.
The problem is as following: I cannot repair permission using Disk Utility.
What happened first was that I wanted to install a program from a mounted drive, however a Pop up occurred and said the framework of installer was incorrect.
After that, I went to Disk Utility and clicked repair permissions when a Pop up like this came up:
http://img219.imageshack.us/img219/2582/picture1mt4.png
What is the problem?
Thank you for any help,
Daniel

-are you running Disk Utility from the HD or booted to the instal disk?
-what are the affected files?
If the file(s) was not installed by the mac OS X installer, Repair Permissions will not fix the issue
Tip:
If the files are located in your home folder,
boot to instal disk#1,
choose Reset Password Utility from the menu bar
and "Reset Home Directory Permissions and ACLs".

Disk Utility not working under cmd R mode

I upgraded my OS to 10.8.2. After doing so, when I do my normal system backup with Disk Utility, the system goes into sleep mode and the backup stops. I've done this many times in the past so I am not new to this. I've read a few articles/posts with people having the same issue. Why is apple not fixing this important bug? I can't backup my system. I have "verified disk" and it has no errors so that's not the issue. The backup image starts to backup to my usb external drive then the screen dims and the system goes to sleep after about 5% and the flash drive stops flashing so it's not longer backing up. When I press escape or any key, it resumes the backup but this takes hours. I can't sit in front of the computer to keep moving my mouse. HELP!!!
I use Disk Utility 13. I reboot and press Command R and then use the Disk Utility from there. I don't want to use Time Machine. It slows my system too much.

You need automatic, frequent backups that don't require you to shut down the system, and that preserve some history. Using Disk Utility in Recovery is good for backing up a system that won't boot, or when preparing to erase and restore a volume, but what happens if you delete a file and then decide a week or a month later that you needed it?

Disk utility not showing volume

I was having boot issues on a mac mini running OS 10.5 so decided to boot off the DVD and run Disk Utility. When Disk Utility came up it listed the hard drive and the DVD drive but it did not list the volume under the hard drive. This means the volume could not be selected thus all the repair/verify buttons are grayed out. Any next steps? Would rather not have to erase the entire drive.
Thanks,
Jim

James,
I don't know for sure but looking into TestDisk may be of help to your situation. http://www.cgsecurity.org/wiki/TestDisk It claims to be able to restore a bad partition table.
I hope that helps

Disk Utility won't allow me to restore from image

I've been keeping pretty good backups for a while now and I have started using SuperDuper to keep whole DMGs as well as using Time Machine. Today I planned on restoring from an image I had made. However, when I go to use the Restore function in Disk Utility, it lets me choose the disk image but will not let me drag the volume on the destination field.
I've been having startup problems all day and I eventually got a 9972 error in Disk Utility.
I'm having trouble finding my install disks and this is my only real option for today. I can't find much about this on Google either.

There's no point in using a disc image for a backup. Better to simply clone to a backup drive then maintain the clone with incremental updates. Use a normal backup utility such as Carbon Copy Cloner or Super Duper.
As for the 9972 error you will find it's a really difficult error to correct. See the following:
How to Deal with a -9972 Error
Contributed by Fumiaki Kawashima
The error message, "Error: The underlying task reported failure on exit (-9972)" is a serious filesystem error in the Mac OS X Core Foundation. The problem can also lead to other critical errors such as "Keys Out of Order," "Invalid node structure" and/or "Invalid sibling link." The causes and scenarios vary. Troubleshooting a solution may depend upon computer configuration and whether the -9972 error is accompanied by other critical errors. This issue can also lead up to a kernel panic. If the error occurs when an external FireWire device is connected, disconnect it until you verify the device's compatibility.
Symptoms:
In most cases, you are unable to restart from Mac OS X.
* A volume is grayed out or not mounted with or without a kernel panic.
* A folder with a flashing question mark may appear.
* A bad partition map may be reported.
* A target disk mode solution may not work.
* Most likely, Disk Utility, Norton Utilities, TechTool and DiskWarrior cannot fix the issues.
* The high level disk format (Standard format) may unable to perform.
* You may unable to re-initialize the hard drive.
* A disk physically malfunctions in the worst case.
Example of an accompanied error message:
DiskWarrior normally fixes 1 to 6, but cannot fix errors 7 to 10 if the symptoms are very bad. There is no definite case.
01. Volume check failed
02. Invalid B-tree Header
03. Invalid map node
04. Invalid extents entry
05. Invalid clump size
06. Incorrect block count file
07. Invalid node structure
08. Overlapped extent allocation
09. Keys Out of Order
10. Invalid sibling link
Related documents:
What to Do When It Finds an Error
Technical overview of disk volume structures
Possible causes:
* Third-party FireWire device or enclosure, or other peripheral devices.
* Third-party mass storage drives or PCI card issues.
* Incompatible third-party kernel extensions.
* Mac OS X installer disc is improperly treated.
Solutions:
If possible and needed, back up data before troubleshooting. Methods (4) and (5) are for Power Mac desktop computers other than G5 models. The best bet is method (4) if you encounter multiple bad errors.
1. Unplug the power cord. Disconnect all third-party hardware except Apple keyboard and mouse before you start.
2. Do NOT re-install any third-party software/hardware until you completely solve the issue(s) and carefully investigate the compatibility with Mac OS X 10.3.x you install.
3. If another critical error "Invalid sibling link" is detected at any phases, disconnect and reconnect all internal power cords and data cables for hard drives and any ATAPI device. To do so, you may need to read the computer's CIP Instructions in advance. Normally, you do not need to remove third-party RAMs.
Method 1:
(1) Start up from Mac OS X 10.3.x Panther Full Install CD or DVD.
(2) Re-initialize and re-partition the hard drive. RECOMMENDATION: Select "Zero all data" option if "Invalid node structure" or "Keys Out of Order" error is detected.
If this method is of avail, go to Method 2 or greater.
Method 2:
(1) Start up in Mac OS 9.2.2 and shut down the computer.
(2) Start up from a copy of a Disk Warrior bootable CD for Mac OS 9.2.2.
(3) Run DW to fix the damage(s).
Method 3:
(1) Unplug the computer.
(2) Find a second ATA drive and jumper it as MASTER. Jumper the hard drive in question as SLAVE. Verify the jumper pin settings.
(3) Install Mac OS 9.2.x system on the MASTER drive, and update it to Mac OS 9.2.2.
(4) Start up from Mac OS 9.2.2. Re-initialize and re-partition the damaged hard drive with Drive Setup using the "Zero all data" option. Unplug the computer and reconfigure the jumper pin setting on the repaired drive for MASTER and the second drive for SLAVE.
(5) Restart from Mac OS X 10.3 Panther full install CD. Re-initialize and re-partition the repaired drive to install Mac OS X 10.3. Update to Mac OS X 10.3.7 via Software Update. Repair the disk permissions after each Mac OS X 10.3 installation and Mac OS X 10.3.7 update.
You may want to try starting up from Mac OS 9.2.x Full Install CD instead of from (2) to (4).
Method 4:
(1) Find a desktop computer that has an ATA controller PCI card (SCSI environment) and has two hard drive bays. This will make your damaged drive appear as a quasi-SCSI hard drive. Mac OS 9.2.2 must be pre-installed on the computer. I recommend a host computer that installs an Ultra DMA/xxx or xxx (ATA-x) interface equal to or better than the damaged drive with backwards compatible.
(2) Set the host computer's primary drive as MASTER and your damaged hard drive as SLAVE and install the damaged drive in the second drive bay of the host computer. Verify properly configured jumper pin settings in advance.
(3) Start up the host computer from Mac OS 9.2.2. Launch the "Drive Setup" utility. Re-initialize the damaged disk on the second drive using the "Low level format" option. It may take hours but less than "Zero all data" option. Note: Normally, a low level format with a quasi-SCSI drive takes much less (30 - 40%) time than an ATA configuration drive. Note that "Low level format" fixes all difficult logical damage.
(4) Put the fixed disk back in your computer's drive bay. Re-configure the jumper pin setting to MASTER before you place it into the drive bay of your computer.
(5) Restart from Mac OS X 10.3 Panther full install CD. Re-initialize and re-partition it to install Mac OS X 10.3. Update to Mac OS X 10.3.7 via Software Update. Repair the disk permissions after each Mac OS X 10.3 installation and Mac OS X 10.3.7 update.
Note that Panther's Disk Utility does not implement a "Low level format" option.
Method 5:
If Method 4 does not work or fix the damaged drive, let me know. You may need an advanced technique to fix it if the drive is physically not a problem.
OPTION:
Purchase a known good hard drive that conforms to your computer's ATA specification. Fix the damaged hard drive some other time. Nowadays, prices of hard drives are inexpensive.

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.

Emac disk utility not detecting ibook hardrive in Firewire mode

ok so i got this ibook g3 (800 mhz version) with no os on it so i hooked it up to my emac via firewire and booted the ibook in the firewire mode. i go into the emac disk utility to format the drive and its not there. i tried booting my emac in fire wire mode and the ibook finds the Emacs drive as a bootable drive. i tried booting the ibook from the drive but all that happed was getting the apple logo with the loading thing below it. i think the ibook is unable of booting since its 10.5.2. so any reason why the disk utility on the emac isnt finding the drive or is it a bad drive?

thanks for the help, i'm pretty sure its a bad drive or a lose connection now, i used my emac restore disk with 10.3 on it and was able to find the disk drive with a disk in it on the ibook in TDM but not the hard drive. guess im going to have to do the 20+ screw surgery on it to put in a new hard drive/look at the connection. i should just save and buy a macbook lol
