Using Disk Utility to fix disk/Startup disk

Hi,
I'm trying to use Disk Utility to repair my hardrive. I have tried starting up with the mac os x dvd that came with my computer, and holding C. However when it gets to the loading screen with the grey apple, the disk ejects.
I've also tried holding down the option key, but its not recognising the disk, just the harddrive.
My dvd drive is working with other disks, and the disk is on good condition.
I'm on a mac book pro, running 10.6.8. The disk is for mac os x 10.6, and is the original one the mac came with.
Can anybody help?

The disk may be damaged. Have it checked at an Apple store and if needed order a new one. In the meanwhile try a safe boot.
Try a Safe Boot
If you're using Mac OS X 10.2 or later, you can start up your computer in Safe Mode, which includes an automatic disk check and repair. If you're using Mac OS X 10.1.5 or earlier, skip to the next section. A Safe Boot, which starts up your computer into Safe Mode, may allow you to start up your computer successfully using a reduced version of the system software. To do this, follow these steps:
Start up in Safe Mode.
After the system has fully started up, restart your computer again normally.

I accidently used Disk Utility to fix a partition. I cant boot in with any USB drive. Help.

I accidentally used Disk Utility to fix a partition. It erased it. I desperately need to restore it.
I have an imac without a cdrom. How do I create a bootable usb with testdisk as for some bizarre reason it seems impossible to create a bootable usb drive for osx. I tried GParted and the ultimate boot disk that both have test disk.
I am stumped. Why can't I boot into my imac with a usb? I have a mac air that I just cant seem to create a usb drive with testdrive thats bootable. I even tried rEFit but no luck.
Anyone have an idea? How do I fix my system ?

I have an imac OSX 10.8.
I tried creating a usb drive of testdisk on my mac air so that I could use it to boot into the iMAC and restore the partition table.
I created it using:
hdiutil convert -format UDRW -o target.img ~/Desktop/ubcd530.iso
dd if=./target.img.dmg of=/dev/rdisk1 bs=1m
It did not work. It would not boot. I also tried Gnome Partition tool and that did not boot either. I need my old system as it has important data
Any tips? Thanks!

How do you fix bad blocks on an external hard drive without using disk utility

so basically does anyone know how to fix bad blocks on a external hard drive without using disk utlility please

Oh...if you have data you are trying to save then its best to try cloning the drive to another one, which should save its data as-is to another drive. Hopefully you can do so without there being hangups around the bad blocks and keep at least most of your data intact. I'd recommend you try using Carbon Copy Cloner to do this, but you will need a secondary drive that is at least the size of the data on the problematic drive.

I have an MacBook Pro 10.6, using disk utility I tried to verify my disk, but it came up with the message, please use your start up disk, I tried this, starting the computer up and pressing C, but it ejected the disk, the same thing happened while I running the computer. Is the hard drive damaged as laptop doesn't seem to recognize the start up disk ? If so, I presume I will have to put in a new one.
There haven't been any problems with the computer, apart from a sticky curser,I have run a permissions programme from disk utility, there were a lot of different ones, but it seem to be able to fix them.
Any comments or ideas ?
Thank you in anticipation.

First backup your users files off the machine to a external storage drive (not TimeMachine!)
Most commonly used backup methods
Next to startup from the disk, have it inserted, hold c or option/alt (wired or built in keyboard) and then boot the computer and or select the disk when it appears and click the arrow.
Disk Utility is under the Utilities menu on the second screen.
Step by Step to fix your Mac
If you used the wrong 10.6 disk, it will spit it out or have issues, use the one that came with that machine or if it's defective, call Apple for a new one.

TS2570 Question re: "Start from your Mac OS X Install disc; use Disk Utility"

I've worked my way through the step-by-step trouble shooting in the TS2570 article up to "Start from your Mac OS X Install disc; use Disk Utility". So far, every step results in the same outcome - my formerly trusty 2007 Intel duo core iMac (24") will not start up, freezing on a grey screen with a blinking question mark on a folder. I don't completely understand this next step. I have both a Leopard and a Snow Leopard disc. I'm not positive whether these were for the iMac, or my old Macbook Pro. I assume this makes a difference.

Question (?) Mark, Blinking Folder, or Gray Screen at Startup
These are related but not identical issues. Their causes are outlined in Intel-based Mac- Startup sequence and error codes, symbols. Solutions may be found in:
A flashing question mark appears when you start your Mac
A flashing question mark or globe appears when you start your Mac
Mac OS X- Gray screen appears during startup
In most cases the problems may be caused by one or more of these:
a. Problem with the computer's PRAM - See Resetting your Mac's PRAM and NVRAM.
b. Boot drive's directory has been corrupted - Repair with Disk Utility.
c. Critical system files are damaged or deleted - Reinstall OS X.
d. The disk drive is physically non-functional - Replace the hard drive.
Note that the information I have provided is what Apple recommends, If other users suggest different solutions than found here, then be sure what they recommend does not impact on your warranty, if any, or ability to get continuing Apple service.
Please don't start removing drives or changing cables unless you know what you are doing and have exhausted other non-invasive alternatives outlined here. If you perform any work yourself that is unapproved by Apple, then you will void any warranty you may have and lose all further Apple Support.
Repair the Hard Drive and Permissions
Boot from your Snow Leopard 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 Utilities menu. After DU loads select your 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 click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
The main difference if you are using Lion or Mountain Lion is that you must first boot from the Recovery HD. Simply boot from the Recovery HD to perform the above.
Reinstall Snow Leopard Without Erasing The drive

Unable to use Disk Utility to repair disk.

Hi all
I have been having some problems trying to transfer movies from computer to my iPod. Someone just suggested that I use Disk Utility to verify disk permissions, as well as the disk. I was able to verify disk permissions and repair them. Noticed the some had something to do with iTunes, so that might fix my problem with transferring movies to my iPod. I then tried to verify the disk, but I got the following error "Error: The underlying task reported failure on exit." Also this program shows that the following "Checking volume bitmap.
Volume Bit Map needs minor repair
Checking volume information.
The volume Macintosh HD needs to be repaired.
Error: The underlying task reported failure on exit
1 HFS volume checked
Volume needs repair"
The <Repair Disk> button is not darkened, but is grey, such that is not an option. Any other way to repair this disk.
Thanks
Michael

The startup drive can only be repaired from another drive.
You have to boot from the install disk.
To do this: Insert the Install Disk 1 into the drive and then select Restart; when you hear the chime hold down C key until the apple logo appears.
This will take you to the installation software, but you do not want to install.
Select your language, then go up to the top menu bar to Utilities in 10.4 and navigate to the Disk Utility application.
Select the start up drive, then go to the First Aid pane where you can click on Repair Disk.
If it finds errors, repeat the process until it reports no errors.
After these repairs, quit the application, and restart normally.
Once restarted normally run Repair Permissions from the Disk Utility application found on your hard drive in Application/Utilities.

Problems erasing window bootcamp partion using Disk Utility

Hi guys, ive removed my windows partion before in the past without any hiccups, but this time i seem to have run into some problems.
If i go into boot camp assistant, it wont let me proceed beyond the start menu. When i click continue it says
"The startup disk cannot be partitioned or restored to a single partition.
Back up the disk and use Disk Utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using Boot Camp Assistant again."
So i went into Disk utility to erase the Windows partion, only now i get this message
"Volume Erase failed
Volume Erase failed with the error:
MediaKit reports checksum operation failure."
I dont have any other programs such as diskwarrior, and in the past Disk utilitiy served me well. Im just wondering whats going on here, and if anyone is able to help fix this problem? Thanks in advance

Hi thanks for your help man, but i still cant get it to restore the partion. If i go into the partion tab i see my two partions under the Volume scheme... but i cant do anything as it is all greyed out. Would you or anyone else have any recommendations... or should i invest in Diskwarrior? at the moment disk utility is just not working out for me. Thanks

MacBook stuck on apple logo. Repaired disk using disk utility, but when I restart, I'm still stuck on apple logo. Please help!

My MacBook is stuck on apple logo and heats up. I tried restarting in safe mode but it's still stuck. I also tried to repair the disk using disk utility. It says that HD is ok, so when I restart, I'm still stuck on the logo. Is there a way I could fix this without loosing my files?

Restart your Mac while holding down the Command + R keys so you can access OS X: About OS X Recovery
From there you can reinstall OS X, repair the startup disk, and restore from a Time Machine backup.
FYI ... wiht ML installed, the only way to repair the startup disk is OS X Recovery, not the Disk Utility app installed on your Mac. You can verify but not repair.

Transferring data from one HDD to a new HDD using disk utility?

I do not have a time machine backup of my HDD. I was wondering if it is posssible to use disk utility to restore data from the old HDD to the new HDD. Will I need the system disks to partition the new HDD first or is this even possible. If it is possible, will everything transfer using the Restore in disk utility?

How to replace or upgrade a drive in a laptop
Step One: Repair the Hard Drive and Permissions
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, Leopard or Snow Leopard.) After DU loads select your 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 click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
Step Two: Remove the old drive and install the new drive. Place the old drive in an external USB enclosure. You can buy one at OWC who is also a good vendor for drives.
Step Three: Boot from the external drive. Restart the computer and after the chime press and hold down the OPTION key until the boot manager appears. Select the icon for the external drive then click on the downward pointing arrow button.
Step Four: New Hard Drive Preparation
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your new 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. Otherwise, click on the
      Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from
      the drop down menu to one. Set the format type to Mac OS Extended
      (Journaled.) Click on the Options button, set the partition scheme to
      GUID then click on the OK button. Click on the Partition button and
      wait until the process has completed.
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 can take up to several
      hours depending upon the drive size.
Step Five: Clone the old drive to the new drive
1. Open Disk Utility from the Utilities folder.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Check the box labeled Erase destination.
5. Select the destination volume from the left side list and drag it to the
      Destination entry field.
6. Select the source volume from the left side list and drag it to the
      Source entry field.
7. Double-check you got it right, then click on the Restore button.
Destination means the new internal drive. Source means the old external drive.
Step Six: Open the Startup Disk preferences and select the new internal volume. Click on the Restart button. You should boot from the new drive. Eject the external drive and disconnect it from the computer.

Clone Drive using Disk Utility

Greetings,
Recently my 15, Aluminum FW800 has had the black screen of death. where I can only make out the faintest images on the screen. I took it to my local Genius bar, where he suggested that I send it in for the flat fee of 320 to get it fixed. I figured thats a good deal, so I agreed.
The problem, however, is that he said they may replace the hard drive... thus I need a complete backup of my drive. I used the backup utility in Tiger and selected the entire drive, and 4 hours later I had it copied to an external drive. However, I have also heard that you can clone a drive using disk utility. I figure if this is possible, i might as well try, since I have the space and redundancy is the key to an effective backup.
As mentioned above, though, I can only barely make out the screen, and have no instructions on how to do this backup. Does anyone know of a link that will guide me step by step through this process? I would hate to press the wrong button and erase my drive before its necessary.
Any help would be appreciated.
Thanks

Don't forget that applications have Help menu and Disk Utility has Restore feature (tab).
Before you start, make sure to do Get Info on the drive you want to restore to (target) and turn OFF the "Ignore Ownership" first.
Click on the left side icon for the volume you want to backup (source) and drag it into the appropriate field. Same for target volume.
Apply and sit back while it copies.
When done, use First Aid to Repair Permissions on the target (I would also do same for your source before you begin).
If you don't see and can't repair permissions on the target, something isn't right.
Now make sure you can boot from the target. Make sure it shows up in Startup Disk and try.

Cannot repair disk errors for OSX boot volume using Disk Utility while booted from different disk

I have tried three times to repair my boot volume (OSX 10.6.8 Snow Leopard) permissions using Disk Utility while booted up on a different volume (running Snow Leopard 10.6.4). After hours of Disk Utility reporting that it HAD fixed the problems, an immediate click of "Verify permissions" immediately results in the apparently same continuous stream of permission errors.

Then better luck next time around. Here are some ideas for then:
How to Install Lion Successfully - You must have Snow Leopard 10.6.7 or 10.6.8 Installed
A. Repair the Hard Drive and Permissions:
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. Then select Disk Utility from the Utilities. After DU loads select your 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 click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.3.) if DW cannot fix the drive, then you will need to reformat the drive and reinstall Snow Leopard.
B. Make a Bootable Backup Using Restore Option of Disk Utility:
Open Disk Utility from the Utilities folder.
Select the destination volume from the left side list.
Click on the Restore tab in the DU main window.
Check the box labeled Erase destination.
Select the destination volume from the left side list and drag it to the Destination entry field.
Select the source volume from the left side list and drag it to the Source entry field.
Double-check you got it right, then click on the Restore button.
Destination means the backup volume. Source means the internal startup volume.
C. Important: Please read before installing:
If you have a FireWire hard drive connected, disconnect it before installing the update unless you will boot from this drive and install the update on it. Reconnect it and turn it back on after installation is complete and you've restarted.
You may experience unexpected results if you have installed third-party system software modifications, or if you have modified the operating system through other means. (This does not apply to normal application software installation.)
The installation process should not be interrupted. If a power outage or other interruption occurs during installation, use the standalone installer (see below) from Apple Downloads to update. While the installation is in progress do not use the computer.
D. To upgrade to Lion:
Purchase the Lion Installer from the Mac App Store. The download will start quickly. Lion is nearly 4 GBs so a fast internet connection is essential. Download time could run upwards of 4 hours depending upon network conditions and server demands at the time.
Boot From The Lion Installer which is located in your Applications folder.
Follow instructions for installation.

HT1553 Does using Disk Utility also backup MSOffice 2008 (Mac) software already installed on my Macbook Pro with Snow Leopard? If not, how would I do that?

Hi,
I'm looking to upgrade from Snow Leapord (10.6.8) to the new Mountain Lion. Have a lot of applications and softwares that I would like to back up when installing the new OS, such as MS Office, Adobe Photoshop and Illustrator. Any ideas on what is the best way to do that.
I'm not too tech savvy, so a simple solution would be appreciated.
Thanks,
Shyam

If your not very tech savvy, I would have someone assist you in the upgrade process as your about to inflict major change on your life and computer.
There are some things to consider before you upgrade.
1: The age of your machine:
My advice has been if your Mac is less than two years old and has a dedicated graphics (not all only Intel HD 3000 or 4000 CPU graphics like the 13" has)) then you stand a very good chance of 10.8 (or 10.7) running fine on your machine.
In either case you need to check the specifications of your machine to see if it meets Apple's requirements, and unfortunately those requirements are a bit low, resulting in a slower machine when you upgrade.
https://en.wikipedia.org/wiki/OS_X_Mountain_Lion
https://en.wikipedia.org/wiki/Mac_OS_X_Lion
(note: 10.7 is no longer being sold via the AppStore, you should upgrade to 10.8, however some machines can't, you can call Apple Sales to upgrade to 10.7)
If your machine originally came with 10.5, I would say forget it. Mac's don't last forever and laptops usually have a life of about 4 years with normal use. Desktops last longer of course and can withstand more OS X upgrades if Apple allows it.
2: The age of your software.
10.7 and 10.8 will not run PPC based software of old like 10.6 does, also upgrading to 10.8/10.7 may require expensive software upgrades that can hit you unexpected. Consult this site and your other needed software and hardware drivers/software (for printers/scanners,custom keyboards/mice etc) BEFORE you upgrade the operating system.
http://roaringapps.com/apps:table
3: Carbon Copy Cloner or SuperDuper "clone" (payware)
Your OS X boot partition to a new/reliable, blank powered external drive and use Disk Utility to Repair Permissions on both afterwards. You can hold the option key down and boot from this clone drive to use the computer like before if your OS X upgrade fails and the machine gets bricked. You can also use Disk Utility to erase the entire internal drive and reverse clone if you find out the OS X upgrade is not to your liking.
Make sure all other drives are disconnected, like TimeMachine when cloning or upgrading OS X, thus when you reboot TimeMachine doesn't self update itself, which can lock you out from going back in time to restore from.
Note: If you have Bootcamp, you can clone that with WinClone (payware) to another drive and recreate Bootcamp later and restore it.
4: Some firmware updates can possibly "BRICK" your hardware
Firmware updates progress in a forward manner and can't be downgraded, so what sometimes occurs is a software error by programmers or a hardware glitch on your machine won't 100% cooperate with the firmware update and thus your machine will fail to function. Sometimes even a interruption in the OS X upgrade or firmware update process will cause the problem. When this occurs, a trip to a Apple Repair is in order and if your machine is out of AppleCare (3 years) or the 1 years standard warranty your looking at a very expensive logicboard replacement. At this time you usually consider the cost not worth it and rather spend the money on the newer machine, especially if it's 2-3 years old. This can come as quite a shock as you expected to pay $20 for a OS X upgrade and now have to buy a whole new machine.
You can't not upgrade the operating system for security and bug fixes, however you make sure you have AppleCare that will protect you for three years if such a hardware bricking occurs. If you don't have AppleCare you might want to reconsider taking the chance upgrading the operating system and thus the firmware.
AppleCare can be purchased within one year of the original machine purchase, it gives one 3 years of care from the date of machine purchase, not from the date of AppleCare purchase.
5: Market share of OS x versions (apx)
10.4 4.5% security updates > no
10.5 15% security updates > no
10.6 52% security updates > yes
10.7 30% security updates > yes
10.8 2 million upgraded so far, just released
6: Your decision to upgrade or not
It depends upon your computer technical ability, the age of your machine, your software investment and your budget.
Can you afford to pay for professional assistance if your upgrade doesn't go as expected? Are you in AppleCare?
Can you afford to pay for upgrades to third party software?
Can you afford the downtime while your machine is being repaired?
Can you live without the "new features" newer OS versions provide?
Does your hardware even support the newer features?
You might decide the upgrade is not worth it for your older machine and decide to ease yourself into a new machine gradually. I took this approach with my 2006 MacBook Pro, buying a Early 2011 model. I then upgrade to 10.7 on the older 2006 machine and glad I did, because it got bricked. Turned out 10.7 was a pretty awful upgrade and I was out of AppleCare, however 10.8 seems to be "normal" far as OS X upgrades go, some problems but not mass bricking of machines.

I need help with boot camp. "Back up the disk and use Disk Utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using Boot Camp Assistant again."

This message appears every time I try to partition my disk:
"Back up the disk and use Disk Utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using Boot Camp Assistant again."
I verified my Macintosh HD disk on Disk utility and then tried to repair it, but I am unable to click the repair button.
It says it's not available because the startup disk is selected.
I don't know what to do or how to go about both these problems.
Please, any suggestions?

AND MORE TOO MUCH TO COPY N PASTE HELP PLEASE!!!!!

Reset the PRAM
Reinstall the operating system from the dvd (you will not loose your data)

Hi, I have a hard disk failure so to recover my data I am using disk utility to restore the data on an external drive while booting from a second external hard drive. When I perform the operation it gives me an input/output error and stops. Any tips?

Hi, I have a hard disk failure so to recover my data I am using disk utility to restore the data on an external drive while booting from a second external hard drive. When I perform the operation and after having selected both my destination and source drives, the operation begins but soon fails due to input/output error. If I try to create an image of the drive it gives me the same error message. Any help would be much appreciated.

Disk Utility only creates a image of the drive, so it's no help getting exactly what you want, which is your files. If the file structure is messed up or the drive is failing then it's no help.
If you have a external boot drive and you can't access the internal non-booting drive though the typical Finder and windows to transfer your files via drag and drop methods, then you need to install Data Rescue on the external boot drive and it will do as best as it can to recover your files. (works on non-encrypted/non-Filevaulted drives only)
.Create a data recovery/undelete external boot drive
Are you sure you have hard drive failure, or that OS X isn't merely not booting?
Because if the drive is working physically, then there is a host of fixes
