Disk Utility refuses to copy 164 GB to a 318 GB volume.

Hello,
I use Disk Utility (stand alone, on a USB key) to make backups of my system disk
to an external disk and then transfer it from my home system to a MacBook and
vice-versa when I need to travel.
Recently, I upgraded from 10.9.2 to 10.9.3 and, not long later, to 10.9.4. In
the same period, I also had an increase (not a very big one, just a few GB, less
than 15) in the occupied space of that system disk. The current amount of data
on it is 164.64 GB.
I'm not sure if my problem comes from the sub-version upgrade, from the increase
in data size, from both, or from something else. The home computer is an iMac
with a 318.88 GB internal disk. The MacBook has a 500 GB internal disk. The
partitions used on the external disk to make bootable backups are 400 GB big.
I can backup both internal disks to the external partitions (and boot on the
resulting external disk when I check that it is usable). I can also copy the
external backups to the MacBook system disk and boot on the result without
problem.
But, recently, Disk Utility has started to refuse copying the content of the
external backup partitions to the internal disk of the home system. It says
there is insufficient space on the target volume. If the error message is
correct, it means that I cannot backup 164.64 GB of data on a 318.88 GB volume!
For the record, the external backup partitions are OK when verified with SOS.
What's going wrong here and is there a solution?
Thanks for any hint.
Denis MAILLARD.

Unfortunately, OS X only provides Time Machine as a backup solution. Disk Utility is not a backup solution in the true sense of how backup should work. I think you will find that CCC is a better solution than Disk Utility. If you don't like it here are others you can check out:

Using Disk Utility to restore/copy disk - who is correct?

I had two long talks with two separate Apple Care people online today who both insisted what they were saying was right and the other person was wrong.
Hmm....
My question is this.
I have a MBP and the internal HD is currently empty. I've been running off of an external HD for about a year now.
I want to clone my external HD into my internal HD and use the internal HD as my system disk now.
One Apple Care person said to go into Disk Utility, select the source disk, from the tabs on the right hand side select Restore and then drag the source disk into the source field, drag the target disk into the target field and press restore. She said this will make a complete clone of the external HD in the internal HD.
The other Apple Care person said "No no no. You can't do that to clone a system disk that way." He said the best thing was to install a new system and then use the restore as a new system from Time Machine option (where I also have a backup.)
I believe the second method will work, but it's more cumbersome for me because I haven't been backing up everything in Time Machine. I have excluded items, such as podcasts and Parallels disk images.
If I could do this from the external system disk life would be easier.
But is the first Apple Support person right or wrong about this? Can I use Disk Utility to copy the system disk from one external HD to another that way?
Thanks,
doug
p.s. I am not in the market for 3rd party software to deal with this one-time issue, so if possible I would like to accomplish this using OS X included features...

The advantage is CCC has built in routines that "bless" (see the Terminal.app command "bless") the
os x installation so it will boot properly on the new volume it is being installed on.
Disk Utility simply copies (restores) files from one volume to another. Many times this works just fine.
Sometimes it won't boot afterwards. Most of the time (as long as there are no system files missing
or corrupted) a person may "bless" the drive and restore it to working condition.
CCC is not a "magical" application, it is in fact a front end to applications that already exist separately
in OS X (asr, hdiutil, diskutil, bless, etc.).
It doesn't matter to me how you do it. It's your time not mine. Everyone should spend some time
behind the command line in terminal. I do many tasks using the command line, including and not
limited to complete system restores, backing up data, disk partitioning, installing software, disk
repair, permissions repair, ACL management, restoring data, managing disk images, network
management, user management, file management, etc. Many people are fearful of the command
line. I feel just the opposite, I'm fearful without it.

Disk Utility refuses to work because of Lion!

I want to resize and add a partition (i.e. split a partition into two smaller partitions) on my hard drive, and I get the following error:
“Partition failed with the error: This operation requires a newer version of Mac OS X for this disk”
This is interesting (and annoying) because I used this exact computer and OS X version, 10.6.8, to format and partition this drive in the first place.
The reason must be the copy of Lion and/or the copy of the Lion installer (the full, “offline”-enabled installer that I made with the help of instructions) that I cloned onto the drive with Carbon Copy Cloner. I also cloned the Lion Recovery partition over. It probably also matters that I booted from all three partitions once (to test that they worked).
So...
what did Lion do to the partition map or whatever that causes the 10.6.8 Disk Utility app to no longer be able to change it and why?!
how do I undo this so I can use 10.6.8 Disk Utility to modify the partitions again?
I know I could just use 10.7's Disk Utility to get the job done now, but I don't want to be dependent on “OS X Vista” in the future.

You do not have to erase the HD. The problem is almost certainly the presence of the hidden "Lion Recovery" partition -- the Snow Leopard version of Disk Utility doesn't understand what it is so for safety's sake it won't let you change the partition map.
If you are willing to sacrifice that partition, you should be able to use Snow Leopard's Disk Utility to do what you want, although I can't guarantee this will work, or that it won't cause some unexpected problems with Lion. However, I have done this with a drive that originally had both Snow Leopard & Lion on separate partitions that I wanted to dedicate to Snow Leopard only, & it works fine for that.
With that understood, you can do this in Terminal. First, use "diskutil list" to get the IDENTIFIER value for the Lion Recovery partition. An example would be:
3: Apple_Boot Recovery HD 650.0 MB disk1s3
The IDENTIFIER value here would be disk1s3.
Now, erase the partition, converting it to a normal HFS+ volume Snow Leopard's Disk Utility will understand, with the following command, replacing {IDENTIFIER value} with what you got from the list command:
diskutil eraseVolume HFS+ Blank /dev/{IDENTIFIER value}
An example would be:
diskutil eraseVolume HFS+ Blank /dev/disk1s3
IMPORTANT!! The previous step erases the contents of the partition. If you use the wrong IDENTIFIER value, you will erase the wrong partition, leaving you with a drive that won't start up your Mac, no data, etc. If you are not sure about this, don't try it! You really shouldn't be doing this OR resizing partitions without a backup, but if you are unable or unwilling to back things up, this is your only alternative.
At this point, quit Terminal, launch Snow Leopard's Disk Utility & confirm that it shows a new partition named "Blank," which should be about 650 MB. You should now be able to use Snow Leopard's Disk Utility to resize partitions, delete the "Blank" partition, etc.

Disk Utility failing to copy a disk

I am trying to copy a disk using restore on disk utility. The disk verified just fine, and it says it is copying files but nothing is happening.
I know something is breaking in my computer because It won't boot up normally. and I just want to get my files from the disk. What do I do?

Ok, so you have a external drive your trying to transfer files too, can it be erased?
Becuase while c booted off the 10.5/10.6 disk (you didn't mention your OS X version or hardware) you can set up the external drive (under the partition tab)
Options: GUID Format: OS X Extended (J) and click apply.
Then Erase with Security option Zero all Data to eliminate any poential bad sectors (takes a bit to complete)
Then install 10.5/10.6 onto the external drive and reboot holding the option key down, you can select the external to boot from
While booted from the external drive, you can access the internal drive and recover your files.

Disk Utility Refuses to Format drive to GUID

I purchased a 1 TB wd 10eavs external hard drive, and have tried numerous things to get it to format. Every single time, Disk Utility comes up with an error saying "File system formatter failed" after about 2 minutes. I can format it to NTFS but that is useless as I want to be able to boot with it. Just so everyone knows, I tried many times at each of the following: Erase to Mac OS Extended, Partition to GUID and Mac OS Extended, Partition to Apple Partition Map and Mac OS Extended, and even partition to GUID and NTFS, which also failed, not surprisingly. The only time it successfully worked was when I used Erase to NTFS. Please help as the deadline is approaching to return and I need to know if I need to return it or not. Thank you all!

I am in the same boat. Picked up a 1TB Samsung 2.5" SATA and have been unable to reformat or partition just as bduff9.
Can you format to NTFS and then reformat to MacOS Extended?
I tried using Disc Utility to repair the disc and continue to get the same "File System formatter failed."
Is this just a bad hard drive?
Help me if you can
I'm feeling down
This new 1TB Hard drive won't spin round
Help me back up the files I have found
Won't you please

My disk utility refuses to erase my hard drive

I've been trying for a few years to find some way to reset my mac to factory settings. Every last thing I've tried has failed. I was hoping the disk utility thing to erase it would work but the erase button never lets me to click on it

If you previously encrypted your hard drive (FileVault2) then your drive was enrolled in apple's CoreStorage format. If so, diskutility won't let you perform certain operations, and you'd first need to use advanced diskutil options from the command line ( $ diskutil cs delete ... ) to trash the CoreStorage volume.

Disk Utility can see my drive but not mount/repair a volume on that drive.

Situation:
During a permissions repair on an external drive, the power went out.
Since then, it won't mount. It spins up, lights on etc, and the drive itself shows up in Disk Utility.
The volume is greyed out.
When I select the greyed out volume and select INFO, I get:
     OWNERS ENABLED: NO
     CAN TURN OWNERS OFF: YES
I would think it was a permissions issue since the power went off during repair, and I'm hoping to force-repair permissions.
Tried Disk Warrior (v 4.4)... it mounted but I got this message (despite hardware being fine):
          The directory cannot be rebuilt due to disk hardware failure (-36, 2747)
It's not a hardware issue; the drive is fine, it just won't mount.
What I've done:
Unplugged/replugged drive
Swapped out cables from a similar drive
Attempted Disk Utility on two laptops with same results
Booted from startup disk, ran DU, same results
Ran Disk Warrior
The only way to get the drive to show up in Disk Utility is to open DU, then plug in USB. It shows up every time, but once I attempt something, I have to pull/replug USB.
I cannot make a disk image in Disk Utility.
I have another completely empty 3TB drive that I could back everything up to.
Specs:
External drive, 3TB Western Digital, USB, HFS, no partitions.
Lion, 10.7.3
Mac Pro, 6GB memory, Intel processor
Drive name "WD My Book 1130 Media", Volume "Big Boy"
Suggestions?
Any force-repair terminal stuff?
Any software I'm not trying?
Any tricks?
Let me know if I'm missing some helpful info; I've done screenshots of every message screen; two are included below.
Thanks for any help!

Try this:
Repair the Hard Drive - Lion
Boot from your Lion Recovery HD. When the recovery menu appears select Disk Utility. After DU loads select the desired hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then click on the Repair Permissions button. Wait until the process is completed, then quit DU and return to the main menu. Select Restart from the Apple menu.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.

Disk Utility is refusing to open

Hi,
I recently decided to upgrade to Mountain Lion but I was planning on doing a clean install. The thing is that my disk utility refuses to open. I checked and its saved under application-utilities but the logo is the one of the paper, ruler, pencil and pen one (the one that usually appears when the program hasnt been recognized) and when i try to open it my dock moves a bit and but nothing else happens, their is no jumping logo, nothing. What do you think might have happened? How can I fix it? Could it be something dangerous? Also do you recommend doing the clean install? i am using a Macbook pro 13 inches from mid 2010 with Snow leopard 10.6.8 on it.
Thanks alot for all your help1

Try this;
In FInder go to the Go Menu
HOLD down the Option key to show the hidden Library Folder and mouse click on it at the SAME time.
The finder window will open the hidden folder.
Now navigate to the preferences folder and click to open.
Look for the following files
com.apple.ActivityMonitor.plist
com.apple.ActivityMonitor.plist.lockfile
Move both to the trash.
Reboot Mac and try to launch Activity Monitor again. those files will be recreated and the icon should have returned to normal.

Disk Utility: Restore Failure

I'm trying to restore my laptop from a dmg file. I have the laptop connected to another computer in target disk mode. When I try to restore, just after it starts copying I get this error:
Restore Failure
An error (2) occured while copying. (No such file or directory)
I created the image with Carbon Copy Cloner and hdiuti to make it UDRO formatted. The computer I'm using to try and restore it is a G5 tower running Mac OS 10.4.7 and I'm using Disk Utility version 10.5.6. Does anyone know why I'm getting this error? Should I convert it to some other format? Are there other ways to restore the disk that might work, if Disk Utility refuses to?

Sure you can... You mount the disk image on your Desktop. Run CCC. Select the disk image as Source Disk. Select the hard drive as Target Disk. Go (or Clone).
(also, CCC does not make disk images; it clones)

I want to make a .iso to backup my computer - disk utility won't let me

Just like the title says - disk utility refuses to back up my computer as a disk image. I've tried the hard disk, and the Mac HD volume, but it both cases disk utility tells me "resource busy"...***? What should I do to get around this problem? I thought it might be errors on my hard disk or hd volume, but disk utility seems impotent to take any action saying:
"Verifying volume “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.
Volume Header needs minor repair
The volume Macintosh HD needs to be repaired.
Error: The underlying task reported failure on exit
1 HFS volume checked
Volume needs repair
Are these processes related? Are errors on my HD volume causing disk utility to not backup my computer?
Any and all help is appreciated!
Vincenso

Vincenso, you need to repair that error first, but it can't be done while booted from it.
"Try Disk Utility
1. Insert the Tiger Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk."

External Hard Disc won't mount - Partition Map error. Can't repair with Disk Utility

Happy New Year all and thanks in advance for any support/advise.
I have some important data on an external drive that does not seem to want to mount. The drive is a 500 GB Seagate connected via USB. I am currently on an iMac 3.06 GHz Intel Core 2 Duo running Yosemity 10.10.1
What I've tried:
Multiple computers - connected the drive to various apple computers with the same result.
New enclosure: I have removed the actual HD from the enclosure and connected it using a new one.
Disk Utility: Verifying Disc reports the following error: 'Error: Partition map check failed because no slices were found.' Screenshot below:
I have searched this and other forums and run a few commands in Terminal that seem relevant to the issue, but am out of my depth in terms of interpreting the results. Thank again for your attention!!!
Commands run in Terminal:
diskutil list
diskutil cs list
mount
diskutil info disk1

Select the disk1s1 volume under the main drive entry, then click on the Mount icon in the Disk Utility toolbar if it goes active and see if a volume then mounts on your Desktop. If it does not, then you need to reformat the drive. And, you cannot access the volume in order to copy your data somewhere else. If you are willing to spend money on the problem, then you can always try using a software recovery utility:
General File Recovery
If you stop using the drive it's possible to recover deleted files that have not been overwritten by using recovery software such as MAC Data Recovery, Data Rescue II, File Salvage or TechTool Pro. Each of the preceding come on bootable CDs to enable usage without risk of writing more data to the hard drive. Two free alternatives are Disk Drill and TestDisk. Look for them and demos at MacUpdate or CNET Downloads. Recovery software usually provide trial versions that enable you to determine if the software would help before actually paying for it. Beyond this or if the drive has completely failed, then you would need to send the drive to a recovery service which is very expensive.
The longer the hard drive remains in use and data are written to it, the greater the risk your deleted files will be overwritten.

Time Machine, Disk Utility, and clearing out corrupted snapshots

Hi, all. I've been having some troubling issues with Time Machine and could use your collective insight.
I have a 500GiB external USB2 disk that I've been using for Time Machine since December (the oldest snapshot in Backups.backupdb is named 2007-12-13-222250). Everything worked fine until sometime in late January, when Time Machine decided to ax 2/3 of my Applications directory. Time Machine's logging is terse, so I wasn't able to determine what caused the corruption. The fact that this error wasn't caught and flagged by Time Machine bothers me.
Especially because I discovered this in the process of needing to recover from a crash on my laptop's hard drive -- I had to roll back to a previous, complete snapshot to get all my applications back.
After that I had to engage in some jiggery-pokery to get Time Machine to re-snapshot everything, but things proceeded normally until I received my new copy of DiskWarrior 4.1 last night (although DiskWarrior is an innocent bystander here). I tried to use DiskWarrior to rebuild the directory on the Time Machine disk, but it failed before trying to write anything.
(For those who care: after some back and forth with Alsoft tech support, we determined this was likely because my Time Machine volume has 6.2GB of catalog data, and DiskWarrior works by rebuilding the directory in memory, so it has to be able to fit the whole catalog into virtual memory.)
I was a little paranoid that something might be wrong with the disk after that, so I fired up Disk Utility and told it to repair the disk. It churned for about 6 hours and repaired an extraordinarily large number of hardlink reference count errors, but completed by claiming that the disk had been repaired.
When I next told Time Machine to run, instead of copying over a couple GB of data like it usually does, it started copying 38GB! ***? I took a look at the previous Time Machine snapshots, and discovered that Disk Utility had totally corrupted every snapshot I'd made since last month's fandango. Most of the root-level directories in the snapshots now look like this:

That is clearly, completely wrong, and it alarms me that Disk Utility could cause so much damage to a Time Machine volume.
Since I also use SuperDuper! to regularly clone this disk, it's not as big a nightmare as it could be, but this means that I'm going to have to clear out every snapshot for the last month by hand, both because I obviously can't trust them anymore, and because I keep getting messages like this in the logs:

I'd like to keep the old snapshots if I can. What's likely to happen if I just go and clear out the b0rked backup sessions by hand?
(Hmm... it appears yes, because I just deleted them all and the disk didn't recover the freed space.)
Here's the important question: has anyone else had issues using Disk Utility on a Time Machine volume, and does anyone at Apple have any plans to add integrity checking to Time Machine? As it stands, I don't really feel like I can trust it in its present form, as convenient as it is...

I have trouble with disk utility on my new (1 TB Lacie) as well as on my old (500 GB WD) drive. After doing a backup, du tells me a never ending list of errors like
HasFolderCount flag needs to be set (id = 599567)
(it should be 0x10 instead of 0)
Everything was O.K. before doing the backup; so is the disk to be backupped, according to du.
Up to now, no other problem occurred, but I´d like to clear this issue before my trust in time machine is restored.

Disk Utility can't repair disk; unable to create image

Hi all,
I had posted a couple days ago because my MBP (2011, 1 2.3 GHz Intel Core i5) was running very slow. I ran EtreCheck, and it turned out that my HD had a number of errors. The next day, before I could back everything up, I had the grey screen on both safe mode and regular mode.
I tried Command+Option+P+R and it brought me to the Utility screen where I was able to run Disk Utility. I tried to repair, but the disk was unrepairable. I then tried to create an image of the HD on a new 1TB external drive, but when the progress bar got to about 50%, it failed. I tried this three times and it failed each time. The error message each time was "Input/Output error." Does anyone have any suggestions on how I could possibly back up my HD, or is all lost?
Here's a pic:

Booted into the Recovery Partition, try Disk Utility/Restore to copy the files to an external drive. Note the warning that this will reformat the drive, meaning any data on the drive will be erased.

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

IMac cannot repair disk in Disk Utility

My computer started slowing down when I initially installed Snow Leopard. Eventually it stopped starting up at all, leaving only the white screen of death. I tried without the perioherals and I reset the P-RAM and nothing changed.
The most success I had came when I booted using the Snow Leopard disk. I went to disk utility to repair the disk, but it says "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." I would be willing to but I can't even get that far along to back anything up. Please help! I keep trying different things. Will I lose everything, including my software if I restore??
Thanks!

8. Back up a drive
Looking for a free way to back up a drive? Well, you’ve already got one—Disk Utility’s Restore tab. It’s a somewhat crude tool, but it does work. Launch Disk Utility and choose the Restore tab. Next, select the volume you want to back up in the left column, and drag it to the Source text field. Select the volume that will hold the copy, and drag it to the Destination text field.
If you want to erase the contents of the destination volume before storing your backup files there, select the Erase Destination option. Otherwise, the newly stored data is simply added to the existing files. Click on Restore to make a copy, and the backup process is complete. If you need to use your backup files later, simply reverse the Source and Destination directions.
