Boot Camp and Disk Utility giving Error for my Hard Drive Volume

When trying to partition my Hard Drive with Boot Camp, I get an error message after a while saying that it can't be partitioned because there is an error in the volume and that I should check it in Disk Utility. After running Verify Disk, it had told me that the file count was wrong and that I should repair my Disk. I have leopard installed, but only had access to a Tiger Install Disc, so after booting to that and apparently repairing successfully, I booted back onto my Hard Drive and ran Disk Utility's Verify Disk again. Now it said that my Volume Header needs minor repair. I still get the same message in Boot Camp. Running Verify and Repair Disk from the Tiger Install Disc tells me that everything is alright and the Hard Drive doesn' need repairing. I read on an Apple article that verifying a disk that's booted can produce inaccurate results, and that it shouldn't be worried about, but I can't install Windows because of this! What should I do?

Hi,
you have to boot from the Leopard OSX DVD in order to repair the Leopard OSX volume on your harddisk.
Using Disk Utility from an OSX version that is prior to the one you want to repair can indeed cause more errors than before.
So, search for the Leopard DVD.

Stefan

Can I use Disk Utility to erase Apple TV hard drive?

Can I use Disk Utility to erase Apple TV hard drive?

I don't know, but I doubt it can be done using Disk Utility. I suggest you consult the user manual for it or see if there is a Reset option in the onscreen menues. If you don't have a manual, then you will find one at http://support.apple.com/manuals.

Boot Camp Hangs, Disk Utility is very slow and gives an error.

Hello,
I would like to install Windows for some games.
But my problem is that when I try to make the boot camp partition it just freezes/hangs 50% in. I have repaired my Disk and it says it is OK.
Got a tip that I could resize my current partition to a smaller size then, make it bigger. This would help bootcamp, but it did not it just hangs around 50% again... I let it say over night, and when I woke up I got a error saying something like
"partition failed at checking archives".
Now I am lost, and do not know what the next step is, this is very annoying and not as easy as I imagned.
Hope you can guide me.

I assume this was the "slow boat to China" syndrome using TimeMachine over USB.
Sorry 'bout that, #1 before beginnng partitioning and the rest was "backup before beginning with Boot Camp Assistant"
Disk Utilty RESTORE is a clone style backup (or there are other programs but not on OS X DVD so you need to boot from something), and of course a different interface (eSATA wold be nice, so would TB or FW800) which should have cut it down to less than a day to backup.
60GB per hour and 500GB?

Boot Camp Assistant / Disk Utility Stuck during Partitioning

Hello Apple / Apple customers,
I have a 15" MacBook Pro (Mid-2010) with a 320GB hard drive. I recently partitioned my hard drive to install Windows 7 in order to install and play a Windows game. Everything installed fine, but I discovered that I didn't have enough space partitioned to fit the game (I did not anticipate it taking 14 GB to install). So I deleted the partition. Now I'm attempting to make a larger partition and restore a Winclone image that I made of the previous partition on that new partition. The problem I am receiving occurs when I attempt to make a new partition in both Boot Camp Assistant and Disk Utility. During the partitioning process, Boot Camp Assistant stalls at about 30% and stays that way for hours, and Disk Utility also stalls during the "shrinking disk" part at about 30% as well. Is there anyway that I can fix this? I already tried repairing my hard drive by running Disk Utility via the Installation Disc, and it says that my hard drive is fine. Thanks in advance for the help.

Reinstall Leopard, but first use the Leopard install DVD Disk Utility to reformat the HD to one partition. See:

It's for Tiger, but applies for Leopard as well.

Disk Utility won't recognize new hard drive

Hello,
Thanks for taking the time to read this.
The original hard drive (80 GB) went bad, so I replaced with a new 160 GB Western Digital one. I formatted the hard drive using Disk Utility from the Mac OS X Disk. It worked the first time I booted into Leopard (I just booted up to make sure the OS loaded...didn't install any new software and/or hardware).
Then I shut it down and started it back up, and the computer didn't recognize the hard drive. I inserted the Mac OS X disk and ran Disk Utility, but the hard drive was not recognized.
So now I'm thinking the new hard drive was also bad. So, I ordered another one (Seagate 160 GB) and it to was not recognized when I ran Disk Utility from the Mac OS X disk.
When replacing all of them, I followed directions I found here and other websites. They all said to do it the same way, so I'm assuming the directions for replacing a hard drive in a laptop were correct.
I searched Google and found several posts suggesting using an application called Disk Warrior, but from my understanding, you cannot run it from a disk, it needs to be installed, which is obviously impossible since the hard drive isn't recognized.
Then I ran Open Firmware and did "devalias" from the prompt. From what I can tell in the list of hardware, the hard drive is recognized, but I am not sure. I took a picture of the screen printout but do not see an option to attached it to this post. Therefore, I'll just tell what it said for now and will create an image hosting account so I can add a URL for it later.
In the list, "hd" is in the left column and in the right column of the same line is "/pci@f4000000/ata-6@d/disk@0" (without quotes).
If anybody has any suggestions, they would be greatly appreciated.

Welcome to the Apple discussions.
I've replaced a few hard drives, and in instances where it's not recognized, it's either been a cable connection issue or I've seen others with a jumper issue. Either the hard drive to logic board cable isn't properly set, typically on the logic board side, or a jumper was left on the drive, where typically you can just remove it. I haven't personally had the cable fail, however, that's possible too.
When you pulled the large plug from the back of the original hard drive, did you do it very carefully? It's not like a desktop hard drive plug that you can just pull out ... it needs to be wiggled out, gently. I have a hard time believing two new drives would be essentially DOA, although the first one worked for a bit, which leads me to wonder about the physical connections.
Since you have your original OS X disks, you could try running the Apple hardware test to see if it gives you any error message(s).

Disk utility can't find iMac hard drive

I had to power off my iMac by Pressing the power key and holding it several times over the last few weeks. The last time it wouldn't reboot - I'd just get an apple icon. When I tried a safe boot I'd get the icon and it would change to a no entry sign.
Next I started up from the snow leopard installation disk with the intent of repairing the iMac disk. The installation disk worked but when I opened disk utility it only found the installation disk. It didn't find the iMac disk.
Do I need to make a trip to the Apple store or is there something else to try?

Version:1.0 StartHTML:0000000105 EndHTML:0000004136 StartFragment:0000001438 EndFragment:0000004100
Oh Gosh, I am having this same problem too. I normally do not shut down ever, I reboot often because I have to due to bad wireless reception. Last month, I did a full shut down and unplug due to a terrible storm coming in. When I went to boot up, it took very long and I had booted from my external bootable drive. My saving grace is that since crashing my emac in 2006, I am a rabid "backerupper" (made up my own word). I have been using lacie’s Silverkeeper to make bootable back ups just in case. So When I tried disk utility, it did not see my drive. I used my third party software "Disk Warrior" by Alsoft, it saw my drive, and then I unplugged my external and then booted again from the Snow Leopard DVD and was able to repair. All was well until this weekend. We had a storm come trough quickly and we lost power, now I have the same problem you do but this time Disk Warrior does not see the disk either. I am going to dig around for a while before I hit the Genius bar. I fear the drive is fried. And for me I am not certain this will be worth the dollar amount to replace since this is a 2006 and not upgradeable, but I will check with an outside vendor for price for the drive so I know what I want to do if in fact the Genius bar cannot see the drive either. I do hope you have a back up version, and would suggest having third party software to take a chance to see if you can find your disk. My imac is an Intel duo core 2 GHZ and from what I can tell model number A1174. To get help from the smart people here it would be useful for you to post the rest of your specs. If you don't know the exact model, you can check everymac.com and plug in your serial number. Under the computer stand you will find the serial number and the emc number and you can find out from everymac.com what exact model you have. If I find anything I will come back to this thread and report in. Good luck to you.

Disk Utility not finding new internal hard drive

Hi All
My internal hard drive died recently and I replaced with a western digital drive from newegg..
All the cables are hooked up correctly, including the orange cable attached to the hard drive. Problem is that when I go to install OS X, Disk Utility doesn't even list the drive. Is there something I need to do beforehand? Anyone have any ideas as to why Disk Utility isn't even seeing the drive? Jumpers maybe?
Thanks in advance.
-Aaron

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.

Cannot read partition created by Boot Camp in Disk Utility

Ok, so in trying to get a larger Boot Camp drive, I used disk utility to make a back up og my previous drive onto USB, and then removed the Boot Camp drive from OSX. This afternoon, I tried using Boot Camp Assistant to create a new partition to install windows onto, hoping to restore from the disk image on the USB drive.
HOWEVER, when restarting the computer when Boot Camp Asst. told me to, and it booted to WInXP sp2 disk, I can see 3 partitions on my drive. 1 partition being most of the 160g drive, 2nd partition being 116g of the mac drive, and the 35g of the 3rd partition (what I asked Boot camp to make) However, it doesn't say boot camp partition. I cannot install XP onto any of the partitions I see in the startup disk.
After spending nearly two hours on the phone with a very nice and helpful tech rep from Apple, my cell phone died, leaving us knowing that there is more space reportedly being used on my Mac HD than i have folders using space (only using about 73gigs of space before any of this partition work, now reports using 116 GB). I went back into the XP disk and deleted the 3rd partition, and now there is no gain in space on my Mac HD. We're re-verified and repaired disk permissions, and used the Leopard disk to repair the disk itself. Restored from Time Machine, and still no regained HD space.
Essentially I'm missing 35G of hard drive space now, and I can't install Windows.
I can only see the Mac HD partition on my hard drive. Anyone have a suggestion?!?!

Mac Pro not recognizing bootable DVDs and Disk Utility giving odd results.

My issue is complex, but I'll try my best to explain it as I can.
One has been resolved it seems, but I am including it so that the whole issue can be seen in context.
Friday, May 16, 2014
Last night, after rebooting my Mac Pro from my Bootcamp partition (I'm using Windows 7 Professional if that information is helpful) I received a kernel panic upon Mac OS X booting (Mac OS X 10.6.8).
My first action was to launch Disk Utility to verify the Mac HD, verify was stopped by disk utility citing that I should insert my Mac OS X install DVD and repair the disk.
I tried booting from my Snow Leopard install DVD. After the grey Apple logo appeared with the gear spinning below it remained for roughly ten to fifteen seconds (a little long) — then the Apple logo changed to. A grey prohibitory sign (circle with a diagonal line through it, the spinning gear remained. — I tried booting from the Snow Leopard DVD a few time, same result.
Following this I tried booting using Disk Warrior, same result again.
I tried booting both the Snow Leopard and Disk Warrior DVDs in both my upper and lower optical drives, with no change.
I decided to leave the issue and call Apple Support in the morning
Saturday, May 17, 2014
This morning I woke my Mac Pro from sleep, opened Disk Utility and tried verifying the hard drive to see if it was temporary — same result, 'please insert the Mac OS X install DVD and repair the drive.' — I also tried booting the install DVD again with no result.
I then booted my Mac into Safe Mode to check my hardware.
Upon opening Disk Utility and verifying my Mac HD — the result "Macintosh HD appears to be OK", rand the test again to see if this was an anomaly, but disk returned another pass.
I performed a normal restart of my system, although Finder was a little slower to load than normal, the system booted correctly. — I then launched Disk Utility and verified the Mac HD, it returned another pass.
This confused me, after a call to Apple Support the tech explained that 'sometime a Safe Mode boot will fix problems because it disables all non-essential processes when booting. — That makes sense to me.
However.
The issue of my Mac not recognizing bootable DVDs remains — it reads disks correctly, it just will not boot them.
Other steps I have taken to try and resolve this remaining issue.
1. a PRAM reset. — No change.
2. an SMC reset. — No change.
3. Removal of newly installed RAM. — I have tried both running the old and new RAM separately, no change using either combination.
4. Running bootable DVDs in different optical bays. — No change from both bays.
a. My upper drive is an MCE Blu-Ray/DVD combo drive, but I have booted from this drive before. (Less than six months old.)
b. My lower drive is LG DVD-RAM combo drive, I have also booted from this drive before. (Over one year old, replacement for an Apple optical drive.)
None of the above steps have helped, I still cannot boot from my optical drives — I always receive a prohibitory sign shortly after the Apple logo.
Other system information:
Mac OS X 10.6.8
8GB of RAM (4 x 2GB)
500GB Western Digital Caviar Blue HDD (less than a year old, boot drive for Mac OS X 10.6.8)
1TB Samsung HDD (for data storage and also containing Bootcamp partition)
2TB HDD (cannot remember manufacturer, contains Time Machine backups, as well as data storage)
ATI Radeon HD 5770 with 1GB of VRAM
Sorry for the long post but I really need to be able to boot from my optical drives.

Update: found an old Mountain Lion installation USB flash drive I created a while back.
I am able to boot from the ML USB flash drive, but am still unable to boot from my either my Snow Leopard Install DVD or my Disk Warrior DVD. — I have verified both DVD and they pass verification tests.
This leads me to believe that the problem resides either in the Mac, or in BOTH the Snow Leopard and Disk Warrior DVDs.
Since I am able to boot from a USB drive, I will look into the possibility of creating a bootable Snow Leopard drive, and perhaps also a Disk Warrior drive — at least until I can resolve the 'not able to boot from DVD' issue.

Disk Utility not formatting new internal hard drive

My 2011 mac book pro recently crashed giving me a gray screen with a folder(question mark). I tried reinstalling Yosemite, with no success. I bought a 2tb seagate hard drive, placed it into my macbook, however it's in master boot record. I tried partitioning it under GUID, but it is giving me error signs, as well "waiting for disks to reappear". I am currently erasing the hard drive, I understand that a 2tb hard drive is a huge hard drive and it takes time for it to be reformatted, but it's been over 12 hours and the estimate time remaining just continues to increase. What is happening? What am I doing wrong?

Just returned it, got the new one and same thing happened...I'm pretty confused with this right now. I used it as an external hard drive and it formatted fine. I installed Yosemite on it and ran fine as the operating system as an External Hard drive. However, as soon as I switch i put it into my laptop, it does not pick up or read. I just formatted the hard drive again and trying to install it, but now it is giving me a different error "this disk cannot be used to startup your computer yosemite". It's actually running as my internal hard drive right now and that's is what my computer is giving me.

Disk utility can't repair external hard drive

A couple months back, I had to get a whole new hard drive case for my external because the power cord broke. Anyway, It's worked fine until now...
The hard drive doesn't show up with the other volumes.
It does show up on Disk Utility. When I try to repair or verify the drive, it works up until the end, but then it automatically quits and it says this:
Verifying volume “FIREWIRE”
** /dev/disk1s1
** Phase 1 - Read FAT
** Phase 2 - Check Cluster Chains
** Phase 3 - Checking Directories
Unable to read directory (Input/output error)
Error: The underlying task reported failure on exit
1 non HFS volume checked
Volume needs repair
Anyway, I have 45GB of music as well as movies and photographs that mean a lot to me so I hope I don't have to erase the drive or anything...
Thanks to anyone who helps me out.

Hmm, I can't seem to find anything on Windows (XP) that will fix my exact problem...
Then again, I am the crappiest Windows user ever so, once again, any help would be great.
I searched "disk repair" on the help and support center, and it gave me a bunch of ways to fix the drive depending on the problem. The thing is, none of the problems seemed to match mine...
Your personal data files are missing or have been corrupted, or you want to revert to a previous version of a file.
After updating a device driver, you can log on, but the system is unstable.
After installing a new device, the system is unstable.
Changes made to your system or application settings are causing your computer to run poorly and you do not know how to restore the previous settings.

I'm not really sure what the exact problem is, I just know that it isn't working on the Mac, but it is on the PC.

Disk Utility cant repair my external hard drive?!

I'm using a 1 TB WD external hard drive on my Macbook Pro (OS is still Snow Leopard).
It was working just fine until a few days ago the hard drive does not show on finder. I tried to repair it with disk utility but it gave the following 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."
Of course I cant back up my files, it doesn't even show on finder! It doesn't show on other macs and PCs either!
I did my research on the internet and tried the following commands on Terminal
mount /dev/disk1
and it says "unknown special file or file system."
mount force /dev/disk1
and it says "/System/Library/Extensions/ufs.kext failed to load - (libkern/kext) not privileged; check the system/kernel logs for errors or try kextutil(8).
UFS filesystem is not available."
What does that mean??
I can reformat my hard drive but it has 500 GB worth of files and I'd rather not loose them if possible.. Is it possible?
I'm also trying to save my files using this software Disk Drill, but it takes forever and the showing files doesn't have the proper name.
Is there anything else I could try? I'll really appreciate any kind of help. Thanks!

Use a product such as DiskWarrior to repair the drive; you’re supposed to make backups to guard against future trouble and not while having it.

Using Disk Utility to Clone/Duplicate entire hard drive.

I have read many post that touch on this question but none have cleared up my questions, and many have just lead to more questions on my part.
I want to use the included Disk Utility program to copy my entire hard drive to another.
Because I only plan on backing up the entire drive once or twice a year, I do not feel I need Carbon Copy Cloner or Super Duper. Also I would like to understand how to accomplish this with the application I already have.
Having read all the help pages and posts I can find, I understand the general concept of using the "Restore" function in DU, but have these questions still:
1. My current HD is a 250GB partitioned with one volume "Macintosh HD" I am going to install another 250GB hard drive into bay 2. Do I need to partition this drive first?
2. Do I need to format this drive?
3. Do I need to erase this drive?
4. Do I need to use the security feature to "Zero" this drive?
5. It seems to me that if I am doing a bit for bit clone the partitioning and format from the source drive would just come over in the copy...no?
6. As the source for the "Restore" do I want to select the parent 250GB disk drive, or should I select the "Macintosh HD" volume?
7. As the destination for the "Restore" (if I had to partition and format) do I want the new 250GB drive or the "Backup" volume?
8. If I have to partition and format the new drive first, I understand that I want the GUID partition table and the MAC OS Extended (journaled), can someone explain what the heck that means?

I apologize for missing that part of the intro.
For a new drive here's the modified procedure I suggest:
Extended Hard Drive Preparation
1. Open Disk Utility in your Utilities folder. If you need to reformat your startup volume, then you must boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger or Leopard.)
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Click on the Options button, set the partition scheme to GUID (only required for Intel Macs) then click on the OK button. Set the number of partitions from the dropdown menu (use 1 partition unless you wish to make more.) Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the volume(s) mount on the Desktop.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process will take 30 minutes to an hour or more depending upon the drive size.
Steps 4-6 are optional but should be used on a drive that has never been formatted before, if the format type is not Mac OS Extended, if the partition scheme has been changed, or if a different operating system (not OS X) has been installed on the drive.
