Repair volume from Disc

Hi all...
I'm trying to repair my internal HD by using the SL disc, but my iMac will not let the computer boot with the disc in place. Is there something I'm missing? It just gets hung up on the start screen (white) with the Apple logo. I'm currently running 10.6.6, so I'm not sure if there's a bug in there that prevents this from happening. I do have another Mac but would need clearer directions on how to repair the volume on my 27" using my 24" as the host.

You went too long, or it is now way too severe.
When the system boots, no matter from which drive or device, it scans for other volumes with a system out there.
And in some cases the directory is too corrupt.
Might want to try Single User Mode and FSCK -fy command first and hope that helps.
Normally I'd also add: open case, disconnect the drive. Should then boot and tells you that is where the problem lies.
Of course you also want to rule out and disconnect any cables and devices.
See if you have a spare 30GB on one of your external drives you can shrink and add, and install OS X there.
Do you have a case and pull your hard drive and put in USB/FW case?
Someone should be able to walk you through Target Disk Mode if Google and Apple Search of support articles doesn't. Should be easy enough to find.
And some background on why I swear by Alsoft Disk Warrior (along with CCC or SuperDuper):

Having that external emergency boot drive is useful, to recover, boot from, system maintenance, and so you can run Data Rescue 3 if needed.
So, do you have Disk Warrior? Drive Genius 3? TechTool Pro 5? spare backup drive space?

Repairing permissions from disc -not

Just to put it out there I own 4 mac's currently and have been using them for 10 years and I'm pretty stumped right now. I updated to 10.4.5, decided to repair permissions from disc and I boot up (from a 10.4.x disc probably like 10.4.2 or 3) and I get a diagram of a mouse with an arrow pointing at it showing that it needs batteries! I've never seen this before and I don't use an external mouse so what the heck is this? I read that you're not supposed to use install discs to repair permissions after you upgrade beyond that version. Never heard that before but that's fine. I can't even boot up beyond this mouse diagram thing to repair the disc. Is it the PB or what? Beyond that if you aren't supposed to use a boot disc, how do you repair permissions? Using disc utility in "utilities" doesn't do everything. Maybe someone can straighten me out here.
I've upgraded to 10.4.4 on my dual 2.5 ghz and use the same tiger install disc and or update disc (I have both) and have no problem.
thanks in advance
powerbook 1.67 high rez 15" Mac OS X (10.4.5) 2 gigs ram

thanks for the reply, my understanding is that repairing from disc doesn't get everything, that you need to boot from a dvd or external disc.
any idea why my PB wont boot from either disc? what if I wanted to reinstall, I cant even do that!!
thanks

Won´t repair volume from disk! any ideas?

I´ve tried to install Tiger on my iBook G4 (from 10.3.9). unfortunately it didn´t work "because of an error" (I love this detailed information). I used diskUtility from the tiger-DVD to repair my volume (it says it needs to) - but it stops the process because "an error occured while quitting" ...
What else can I do to repair the volume without erasing the whole thing (with data, software and all) to finally install Tiger? need quick help.
thanks.

An error occurred while quitting?
When you quit the Install disc by backing out with menus, you must change the boot disk in Open Firmware to your hard disk by clicking on the hard disk, one of the choices given you. Did you do this?
When did this error occur.
Logs are great, but you need to get to them. If you've access to another computer, you can create an optical boot disc that starts only Darwin, and has some command-line utilities.
If you were doing a clean install, in the absence of a possible diagnosis, why not just erase your disk; or reformat it as HFS+ Journaled, or just choose these options at the beginning of a clean install and start again?

HT203176 i have a slow macbook, i ran live disk utilities and said I need to repair disk from a cd. did that, I got volume repaired from the external disk. when I reboot from hdd, then run disk utility, I get the same error message i did b4 repair

i have a slow macbook, i ran live disk utilities (from hard drive), turned out I needed to repair disk from a installation disk. Did that, I got the volume (Hard drive) repaired from the installation disk disk. To this point, great!
When I reboot from hdd, then run disk utility, I get the same error message i did b4 repair. I went thru two rounds of this.....
Can anyone help? thanks

Sorry guys, I don't see how to reply to you so I use reply to "me" basically.
So the error I get is "volume header needs minor repair" and then you need to perform repair from the installation disk message.
I did repair not verify from the disk twice. Every time ending in the "the volume had ha been successfully repaired". Then I reboot from the internal disk. Run disk utilities from it, do verify and get the same error message I got before repair. I hope this can shed some light fr you guys. Sorry I didn't include details in the original
MEssage.

HT4904 I need to repair my start up disc so I have to start up from installation disc. In doing so, my computer restarts, I hear the mac sound, then a grey screen and then turns off and goes on in this cycle endlessly. Why can't I restart from disc?

Booting From An OS X Installer Disc
1. Insert OS X Installer Disc into the optical drive.
2. Restart the computer.
3. Immediately after the chime press and hold down the "C" key.
4. Release the key when the spinning gear below the dark gray Apple
logo appears.
5. Wait for installer to finish loading.

How to repair volume

I am using Onyx to fix up my Mac. It is running slow. When I installed Onyx, it stopped and gave me a box that said something about needing to repair volume. It told me to get my Mac install CD, go to Utilities and then to Repair Disc. But when I inserted my install CD all I can do is install. How else can I do this. And oddly, when I inserted the CD, the Onyx box appeared offering my Onyx choices. So I'm not sure what I should be doing at this point. It also instructed me to back up. So not sure how to proceed. Thanks
Running OSX 10.6.8

Insert the Install DVD and boot from it by holding down the C key prior to the startup chime. Then, in the menu options you will find lots of goodies like password reset and the much desired Disk Repair. Run that so you can do a Repair Disk instead of just a Verify Disk. If errors are found, as will probably be the case given OnyX's warnings, repeat the Repair Disk activity until no more are found. Should also do a Repair Disk Permissions for good measure, although you only need to do this once.
The reason you need to restart with the DVD's mini-OS is that the hard disk has to be modified to do the repairs. And this can't be done if the Mac is using it as the boot source. Note that booting from an optical disk takes LOTS of time. Be patient.

Cannot boot from disc

Holding down "C" does not boot from disc. Computer does boot normally. After entering password -- which is accepted -- there is no dock or access to apps.
Reset PRAM does not work.

I just found another possibility:
So you cannot get to single user mode... can you get to open firmware, and reset the non-volatile RAM?
Cmd-Opt-O-F at boot
reset-nvram
set-defaults
reset-all
(each line exactly as shown, followed by <return>)
I'm now able to repair the volumes. Waiting for it to finish and reboot.

Repairing volume with techtool deluxe

My MBP is on the protection plan which means I have techtool deluxe. The software has found an error in the volume. The directions for the software state to restart the mac from the appple menu and hold down the C key while starting the MBP with the cd in the drive. This supposedly is going to start the MBP from the cd and start techtool deluxe's repair programs. My problem is that when I restart holding the C key my MBP just starts up normally. Am I not doing it correctly? Does C key mean the apple/cmd key? Does C key mean the ctrl key?
Has anybody ever used techtool deluxe to repair a bad volume?

Do not use TT Deluxe to repair your drive. It is not compatible with Intel Macs. Instead use Disk Utility. Do the following:
Repairing the Hard Drive and Permissions
Boot from your 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. Now shutdown the computer for a couple of minutes and then restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.1 for Leopard) and/or TechTool Pro (4.6.1 for Leopard) 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.

Repairing volume for 2 hours in Disk Utility?

I recently got the flashing question mark on startup on my MacBook. I booted from the OS X Install Disk and am trying to repair the HD in Disk Utility's First Aid. It's been showing "Repairing volume" in green and "Look for missing items in lost+found directory" with the status bar nearly complete for the past 2 hours - would it ever really take that long?
I'm perfectly content to let it repair and look all night if it's actually doing something but I'm worried that it's not.
My warranty runs out tomorrow so if my hard drive is toast, I'd like to know soon!
Any help would be appreciated.

You might have to invest in a more thorough program like [DiskWarrior|http://www.alsoft.com/DiskWarrior> or [TechTool Pro|http://www.micromat.com/index.php?option=com_content&task=view&id=31&Itemid =83]. Disk Utility is somewhat limited in it's ability to repair damaged volumes (which is why you get the flashing question mark).

TechTool 3.03 Unmounted Hard Drive After Repairing Volume Structure

Hi Apple Discussions! Any help, advice or information anyone can share will be greatly appreciated. So here's what happened:
I have a 17" imac Flat Panel. *After using TechTool 3.03 to repair the Volume Structure (had gotten a 92 Error Message) Techtool would not quit.* I turned off the computer and *when I restarted I heard the foghorn sound instead of the regular start up chimes and then got a* *Kernel Panic (You have to restart your computer.)* Since the computer was a gift I didn't know if it was still under warranty but I called AppleCare anyhow. Even though the warranty has expired the rep stayed on the phone with me and tried to help. She had me eject the TechTool disk by holding down the mouse (who knew?) and insert the OSX disc....*Long story short the Hard Drive is no longer mounted.* She set me up with an appointment at a Genius Bar.
I hooked the imac up to an old ibook via Firewire and accessed the imac's hard drive (can't use my new MacBook Pro because it has a different Firewire pin.)
*I also zapped the PRAM and know it chimes on as usual but I still get the Kernel Panic.*
I was curious so I continued to research and I see *Apple warns to not use TechTool 3.03 to repair Volume Structure errors for OSX 10.4 which is what the imac is running.* Of course, if I knew ahead a time....Is this why the Apple rep helped me even though my warranty expired? *She said they just need to remount the Hard Drive. I'm wondering what that entails and can I do it myself?* I'm not looking forward to lugging my imac down to the Apple Store on 5th Ave. in NYC!
Thank you and sorry for the very long story!

Hi Dale, Thank you for your response. When I use DU to Verify or Repair I get this message:
*Invalid b-tree node size*
That's a pretty serious error. I'm pretty sure even the updated version of TechTool could not repair it.
If I wanted to download the TechTool updater and use it on the imac how would I do that since I can't log on?
I was thinking you could use your iBook at the time. But the TechTool disk is machine specific so that may not work.
I'm taking it in today to a Genius Bar so we'll see.
Hopefully they will run DiskWarrior on it. Otherwise it's an +Erase and Install+. hope you have a backup!
Thank you for your help. I also just learned that it is an imac G5 (oops!)
You are quite welcome! Good Luck!

HT1291 my start up disc is almost full, can i migrate from disc 1 to disc 4 in the same mac pro desktop machine

I have a mac pro quad 8, my start up disc is 500 gig, my time mach disc is 500 gig, i have these in position 1 and 2 in my comp, i have 2terra byt disc in possy 3 and possy 4 in the mac pro, can i migrate in the same mach. from start up disc to disc 4 and once completed can i then change disc 4 to strt up disc bay one position. as such then have a start up disc wich is two terra bytes? and if so how do i go about that. your help is much apreciated , thanks.

Yes, you can. Use Disk Utility to clone one disk to the other:
Clone Lion/Mountain Lion using Restore Option of Disk Utility
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.
     1. Select Disk Utility from the main menu then press the Continue
         button.
     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 Disk 4. Source means the current startup drive - Disk 1.
Note that a Time Machine backup drive needs to be a minimum of twice the capacity of the drive it backs up. If you have a 1 TB startup drive, then you need a 2 TB backup drive if you use Time Machine.

MSI NF980-G65 freezes when trying to boot from disc

I just recently purchased and received an MSI NF980-G65 motherboard to work with my AMD Phenom II x6 1055T, but sadly I have had nothing but trouble.
So far the motherboard posts its bios and has the ability to detect any (and all) of my hard drives when I have them plugged in. The hard drive that has Windows installed on it currently informs me that I need to put in my Windows disc and run the repair utility, which makes sense since I was using a completely different motherboard and CPU before.
It is when I try to press any key to boot from disc that the problem arises. When I press a key on my keyboard while that prompt is on screen, the cursor jumps as if I had hit the tab key and does nothing further.
I have a total of three copies of Windows 7 at my disposal to use, two are DVDs I had burned from using my student discount to get them, and one set (32-bit and 64-bit) were in a retail copy of home premium, all of the discs performed the same action. I had tried using different SATA cables, different power adapters, and even different DVD players to try and remedy the situation.
The hard drive with windows is an IDE hard drive, but I have tried my other SATA hard drives just to be sure, none of which fixed the problem.
I have heard briefly about m-flash, but as far as I can tell, it would appear this new motherboard did come with the latest bios version (1.4).

For the boot, I have tried both setting up the DVD player as the initial boot, and I have tried just selecting it in the boot menu.
As per the posting guide, here are more specific information:
Processor: AMD Phenom II X6 2.8 GHz, 9.0 MB Total Cache, AM3 Socket
Motherboard: MSI NF980-G65 v. 1.2 bios (I'm going to try and flash this to a later now, I didn't know where to look for it before) , 601-7612-010B1004183389
RAM: G. Skill Ripjaw DDR3-1600 PC3-12800 2gb x 1 until I get this working, then it will be x4
Power Supply: Tagan BZ Series 700W
DVD: Samsung SH-S223 DVD burner with Lightscribe
HDD: Western Digital 250GB IDE drive

Grey loading screen when start up + unable to start from disc

When I start up my MBP I get a very slow grey loading screen. After a while it starts up my mac and it runs like normal. So no i finally got sick of the 10 min waiting before start up, I decided to re-instal from disc. When i normally insert the disc it starts. then I select the Instal and it rebooths. But it stays on a grey screen when reboothing.
I also tryed to start it up with C and with holding alt and then selecting the cd. With C i get the same grey screen(Without loading bar and mac logo) and with Alt it just get stuck at selecting the cd.
When I go to Disk Utility then I can use Check disk but not the delete one.
I don't need to back up, just want it to work fine again.
I hope you can help me out.

Hi Arthur, and welcome to Apple Discussions.
While booted from the install disc, have you opened Disk Utility and checked SMART status and run Repair Disk?

'Macintosh HD' missing from Disc Utility

Have 2013 MacBook Pro. Had some minor issues, so checked disc utility. Told to reinstall OS X, as the directories weren't reparable. Tried reinstalling via disc that came with the computer, but could never get back to desktop screen. Tried one last time and the 'Macintosh HD' was missing from Disc Utility screen. Called Apple who said the HD might need to be replaced, which is really unacceptable after 2 years of light use. Ran Apple Diagnostics on Hardware, came back 'no problems found." Two questions: can I get back to HD and how do I get from the reinstallation to desktop? Thanks!!

Boot the MBP with the OPTION + COMMAND + R keys.
If successful, you should see a revolving globe.
This will connect you to the Apple servers.
Follow the instructions and you should see a 4 option menu.
Select Disk Utility and then First Aid. Run Verify and Repair.
Then you can select the OSX reinstall option. It will reinstall the original OSX that the MBP came with.
If no success, then the best option is an Apple store genius bar appointment. The evaluation will be FREE.
Ciao.

Now every time my computer goes into sleep it won't wake up.
The only way it will restart is to pull the mains lead out of the imac, put it back and try until it will start.
This only happened after reinstalling. Only Apple OS was on the imac and so it must be an issue with the software I believe.....
Anyone know how to cure this problem please?
Thanks
paul

This isn't a fix, more a workaround I used when I had wake from sleep problems that lasted from some point in 10.6.x, through 10.7 and into 10.8 (got fixed for me in 10.8.2). It seems to be connected with Bluetooth failing to wake up properly:
System Preferences>Energy Saver and set 'computer sleep' to 'never'.
