Disk Utility- why two lines per disk?

Can anyone answer me as to why there are two lines for each disk in Disk Utility-one is the hard disk type, and the other is the info?

The first line represents the physical disk; the second (and third, fourth, etc.) line represents the volume or partition. A single physical disk could have multiple volumes, hence the outline-type display in Disk Utility.

Why can't disk utility repair iTunes in "Repair Disk Permission"?

Having issues with Disk Utility's not fixing iTunes "Disk Permissions". Have run "Disk Repair Permission" repeatedly to no avail. Same statements keep coming up. None of them ever go away.

Unless you receive a message that states you could not access a file, you don't need to repair permissions. Regardless of what repairing permissions reports, there aren't any problems unless it states it could not repair permissions. Even a fresh permissions database doesn't know what the current permissions should be. It uses what was current at the time the system is installed, and it rarely gets updated.
As updates change things, the permissions database becomes more and more out of date.
Now, if you are having a problem with iTunes hanging up, then that is not normally caused by permission problems.
Do you have any plug-ins or extenstions for iTunes?
Does it occur in another account?
Does it occur in Safe Mode? http://support.apple.com/kb/HT1455

Disk Utility sees problem invisible to Disk Warrior?

Hi all,
In brief: Disk Utility seems to think I've got a big problem, Disk Warrior seems to be unable to fix it.
More detail: I ran verify disk from Disk Utility and was told I needed to repair my startup volume. So I ran Disk Utility's repair disk function from the install CD and it was unable to repair the disk. It was also unable to repair permissions.
So I reached for trusty Disk Warrior and ran that. It rebuilt the directory, reporting various changes, eventually ending with zero errors. That should have fixed it, right?
But then I re-ran Disk Utilty and was told, again, that the disk needed to be repaired.
Here's what happened when I ran DU's repair function from the install CD:
- I selected only the volume containing Mac OS X for repair and Disk Utility reported there's an "invalid leaf record count (it should be 3 instead of 525) and also that '1 HFS volume repaired' but '1 HFS volume could not be repaired'. (I'd selected only my startup volume).
- The verify disk function reports the same
- The repair disk permissions function cannot complete its task. Its error message reads: "Disk Utility internal error: disk utility has lost its connection with the disk management tool and cannot continue. Please quit and relaunch disk utility."
So, I ran Disk Warrior AGAIN (2nd time) and sure enough, it reports that it successfully rebuilt the directory but that the rebuilt version has no changes from the original version (meaning it's ok, right?).
Needless to say, if my startup disk DOES need repair, I want to do something about it. But does it need repair? And if Disk Warrior can't fix it, what can? Could it be that Disk Utility is seeing a problem that's invisible to Disk Warrior?
By the way, I ran DW's manual diagnostic and it said the drive itself was operating normally.
Very grateful if any of you can give me some insight into this.

Hi Allan,
Sure thing. Here's the business.
Disk Warrior (v3.0.3)
DW reports that it's successfully rebuilt a new directory each time I run it. I've run it three times now. The first time, there were differences between the original directory and the rebuilt version and it displayed a message coloured red describing this. On the subsequent two occasions, it has displayed a message coloured green and said there are "no changes to the number or contents of the files and folders" in the rebuilt directory.
DW's manual diagnostic reports that the drive itself is "operating normally."
DU
Running DU internally (from the volume that also contains 10.4.9), it can only 'verify', of course. The volume's name is 'G5 hard drive'. The full message is:
Verifying volume “G5 hard drive”
Checking HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Checking multi-linked files.
Checking Catalog hierarchy.
Checking Extended Attributes file.
Incorrect number of Extended Attributes
Checking volume bitmap.
Checking volume information.
d.",1)
G5 hard drive
Error: The underlying task reported failure on exit
1 HFS volume checked
Volume needs repair
Running DU (repair disk) from the install CD (for Powermac G5, OS X 10.3.5) produces the following report:
Repairing disk for "G5 hard drive"
Checking HFS plus volume
Checking extents overflow file
Checking catalog file
Checking multi-linked files
Checking catalog hierachy
Checking extent attributes file
Invalid leaf record count
(It should be 3 instead of 422)
Repairing volume
The volume G5 hard drive was repaired successfully
Repair attempted on 2 volumes
1 HFS volume repaired
1 HFS volume could not be repaired
So let's say that DW is doing it all right, and the copy of DU on the install CD (10.3.5) is producing an inaccurate result because it doesn't match up with Tiger, I can understand that. But why would the same problem come up with DU run internally from (in the course of the last 24 hours) both 10.4.8 and 10.4.9 (because the problem survived my upgrade)?
On the other hand, Allan, possibly DW isn't the right tool for the job. In that case, do you know what is?
Thanks,
Jason

Time machine: An error occurred while copying files. The problem could be temporary. If the problem persists, use Disk Utility to repair your backup disk.

Time machine backups are failing. I've followed the instructions I found on the Time Machine troubleshooting page (http://pondini.org/TM/Troubleshooting.html) but have gotten to where I don't know what to do next.
Sequence of events:
The main error message is always:

Yesterday, I opened Disk Utility and verified the disk. Got this error:
Error: This disk needs to be repaired using the Recovery HD. Restart your computer, holding down the Command key and the R key until you see the Apple logo. When the OS X Utilities window appears, choose Disk Utility.
I ran Disk Utility and repaired the hard drive. Then I manually started the backup before going to bed, figuring it was going to take a long time to run. When I got up this morning, the backup had failed with the same "could be temporary" error. I checked the log, which says:

You have repaired your boot drive (which is good) but have you repaired your time machine drive? I don't own a Time Capsule so I don't know if disk utility can operate on it. If it can, you should repair it as well. You may need to erase it and start a new backup. That happens to time machine volumes from time to time and is why people who are serious about their data never rely on a single source of backup.

Can I fix a disk with this message?-Disk Utility can't repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.

Can I fix a disk with this message?
Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.

Some problems can indeed be fixed this way. But working from Recovery_HD or Disk Warrior DVDs and working in the restricted environment those provide can be difficult. You can literally spend days working on this problem (while your regular work is unavailable) only to discover the old drive is unsalvageable.
There is no way to know up front whether you are facing a major Hardware failure or a minor software glitch, or something in between. Often you are forced to work from the drive you no longer trust. I continue to recommend you do this work from a different, fully functioning Mac OS X booted from a different drive.
If you have had the foresight to (as The hatter often recommends) clone your virgin install onto another drive for use in such situations, you will be able to recover from such problems in record time. If not, my previous recommendations stands:
Buy a new Drive. Or two. Install Mac OS X from scratch on a new drive, and get your Mac running again. Later, you can use the full power of Mac OS X to attempt to rescue your data, if needed. Then Zero the old drive, to see if it can hold data again reliably.
If the old drive eventually provides some needed data, and is salvageable, Merry Christmas.

Partition errors - "Disk Utility can't repair this disk"

I partitioned my external 1TB WD HD into two drives (950GB + 50GB) using Disk Utility (OS X Mavericks 10.9.1). However the 950GB partition will no longer mount. It is recognised in Disk Utility, but grayed out. "Verify Disk" and "Repair Disk" in Disk Utility lead to the worrying error message "Disk Utility can't repair this disk."
From the Disk Utility logs, the initial partition was successful:
Partition 1:
Name: “Media Centre”
Size: 948.13 GB
File system: Mac OS Extended (Journaled)
Do not erase contents
Partition 2:
Name: “Media Centre 2”
Size: 50.03 GB
File system: Mac OS Extended (Journaled)
Do not erase contents
Mounting disk
Partition complete
Afterwards, I changed the name of the second partition “Media Centre 2” to "BOOTCAMP" (I was going to try to install Windows 7), but then changed my mind and tried to remove the second partition. At that point the log gives the error "Mount of “Media Centre” failed".
Partition 1 ("Media Centre") now seems to be in limbo, stuck as 950GB, and "Verify Disk" and "Repair Disk" in Disk Utility lead to the worrying error message "Disk Utility can't repair this disk". Also in Disk Utility, Partition 1 ("Media Centre") now has the format classification "Mac OS Extended" rather than "Mac OS Extended (Journaled)".
Any idea how I can get my hard drive to mount and get the data back?

In Disk Utility select the Top most entry on the left, the drive model and or manufacturer name and size entry, then click the Partition tab and Repartition it to your liking. If that fails the drive is bad.

what does this mean?? why can't i backup before i have to get my hard drive replaced?!!? arghh

I don't have a TC but rather an external drive, which is twice the size of my harddisc, and it still has plenty of free space. The problem has lasted for 5 days. I even used a different external drive -- still same error message. Needless to say that I have run Disc Utility several times. Can anybody help? Thanks
I am having issues with some USB drives on Mountain Lion.. work perfectly on another computer with Snow Leopard.. not even recognised by ML.
Is the disk recognised?
If so and TM cannot pick it up.. do a full reset of TM and try again.

Clean Install of Snow Leopard
Be sure to make a backup first because the following procedure will erase
the drive and everything on it. See below for how to clone a drive.
     1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
         with your computer. Insert the disc into the optical drive and restart the computer.
         After the chime press and hold down the "C" key. Release the key when you see
         a small spinning gear appear below the dark gray Apple logo.
     2. After the installer loads select your language and click on the Continue
         button. When the menu bar appears select Disk Utility from the Utilities menu.
         After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
         size.) Click on the Partition tab in the DU main window. Set the number of
         partitions to one (1) from the Partitions drop down menu, click on Options button
         and select GUID, click on OK, then set the format type to MacOS Extended
         (Journaled, if supported), then click on the Apply button.
     3. When the formatting has completed quit DU and return to the installer. Proceed
         with the OS X installation and follow the directions included with the installer.
     4. When the installation has completed your computer will Restart into the Setup
         Assistant. Be sure you configure your initial admin account with the exact same
         username and password that you used on your old drive. After you finish Setup
         Assistant will complete the installation after which you will be running a fresh
         install of OS X. You can now begin the update process by opening Software
         Update and installing all recommended updates to bring your installation current.
Download and install Mac OS X 10.6.8 Update Combo v1.1.
You may be able to backup your data if you have an erased external drive you can use. Before you do the above but after you have opened Disk Utility you can try to clone your drive:
Clone using Restore Option of Disk Utility
1. Open Disk Utility.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Select the destination volume from the left side list and drag
       it to the Destination entry field.
5. Select the source volume from the left side list and drag it to
      the Source entry field.
6. Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal startup drive.
Now this will only work if the drive is accessible and can be cloned by Disk Utility. Otherwise, you would need to access your drive from another Mac that you can connect via Firewire - Target Disk Mode.

Error disk utility can't repair this disk...disk and restore your backed-up files

I have been working on a project using an external hard disk. I used my Macbook Pro (2010) to create this project and files (about 31 GB). Now I am trying to open the disk on my iMac (2014) and it doesn't show up. I can see the HDD when I use disk utility but get this message when I try to repair/restore the disc:
"error disk utility can't repair this disk...disk and restore your backed-up files"
The funny thing is that the disk works absolutely fine with my Macbook Pro. What am I missing?
Imac :OSX 10.9.4 , 2.7 GHz Intel Core i5, 8 Gb Ram.

Nico,
Did you find a way?
This just happened to me too.

"Disk Utility can't repair this disk...and restore the backed up files"

Hello, my macbook crashed a few days a go as well and after going to the recovery drive and OX Utilities tried to verify and repair disk it gives me this error "Disk Utility can't repair this disk...and restore the backed up files" is the second time that occurs after replacing the hard drive for a new SSD, i thought my problem was solved and is not. Any Ideas? the only other thing i can think of is the logic board?

Backup your files and arrange for an appointment at an Apple store genius bar for a free evaluation.
Ciao.

My computer is shutting down before fully booting up. I am running the disk utilities program and have this message: Error: Disk Utility can't repair this disk . . . disk, and restore your backed-up files. Can anyone suggest what I should do next?

So, you can't Install OSX to the external?
Or you can't boot from it when you do?
You're not the only one wondering... I'm reminded of the Goose that laid the Golden Egg story.

You can't have received an error message "Disk Utility can't repair this disk...disk, and restore your backuped-up file." since that is pure gobbledegook and isn't even good English.
What may have happened is that
(a) your hard drive has become so full that the operating system can't find any space in which to.... operate.
(b) as macjack says, it has crashed - possibly as a result of (a).
(c) you have been allowing Time Machine to back up to your internal hard drive instead of to a backup disk, which has caused (a) to happen.

External Hard Drive Disk Utility Can't Repair the Disk

Hi,
I have a Seagate 1 TB Backup Plus Drive which was working perfectly fine until I plugged it into a USB hub. It detected it while in the hub and I was able to get files off of it, but when I ejected it from the hub and put it back into the USB slot on the computer it was not detected by finder. It shows up in the disk utility and I clicked verify and repair and it says:
Verify and Repair volume “Seagate Backup Plus Drive”
Checking file system
Volume repair complete.
Updating boot support partitions for the volume as required.
Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
Is there any way to get this to work properly again? Or if not is there a way for me to recover my files on the external hard drive?
Thanks
I have a Macbook PRO late 2011 running OS X Mavericks.

Use a more powerful utility such as DiskWarrior, or a product such as those listed here.

Disk Utility can't repair this disk

I have been having trouble booting. It started when I connected a router to it. It seemed to eat up the free disk space and I only have 77 MB left or something around that.
Anyway, I tried deleting files with command-s commands, and it worked one time and it freed up 2 GB of space. I restarted the computer and when I tried to start it up, it still got stuck in the gray screen with the whirly thing at the bottom. I checked the space and it was 77MB now.
I decided to boot from the Install Disk (Snow Leopard 10.6.0).
I checked Disk Utility first and verified the disk. It came up with the message:
"Error: Disk Utility can't repair this disk .... disk, and restore your backed-up files."
What should I do now?
I have the Mac HD volume on backup already so I don't have to do the back up stage.
Should I erase the disk while I am in Disk Utility?
And format it to Mac OS Extended Journal?
And then install the operating system again?
Thanks.

To answer your questions, first, some other options...
If you fill your disk up that far, you are going to have problems. Don't ever do this, 10% is a bare minimum, you may need even more, depending on the size of your disc.
I have seen before where a disc repair utility couldn't perform its function simply because there was not enough slack space available on the drive. While I have never seen this with disc utility, it is possible that the disc is repairable as-is, if you could just free up a couple more gigs of space first.
Secondly, you could also try Disk Warrior, or to a lesser extent, Techtool Pro, or even iDefrag. I have personally never had Techtool Pro fix anything that Disk Utility or Disk Warrior couldn't fix, so I hesitate to even mention it, but I have had Disk Warrior and iDefrag clear up problems that Disk Utility either couldn't detect, or couldn't fix.
If you are still in dire straits, you should re-partition the drive using disk utility. This is the safest route, then go from there.
good luck!
