Repairing disk with another installation disk??

My startup disk is almost full so I tried to repair disk in Disk Utility but only 'verify disk' was available, which led to the following error message: "This disk needs to be repaired. Start up your computer with another disk (such as your Mac OS X installation disc), and then use Disk Utility to repair this disk." I have recently moved countries and cannot seem to find my installation disk anywhere (stupid, I know). Is there another option, such as using someone else's installation disk (since nothing is actually installed from the installation disk in this process, right?) or does it have to be my own installation disk? It is an old MacBook (2007), running OSX 10.6.3. Thanks in advance!

Okay so I got my hands on another installation disk, inserted the disk and restarted the computer while holding down the 'c' key. But when the computer started up an error message appeared saying "Mac OS X can't be installed on this computer. If you want to restore from a Time Machine backup, click 'Restore from Backup.'" When I started down that path of restoring from my time machine backups it warned me that everything on my startup disk would be wiped, and that seemed like a bad idea, so I backed out of that process and am now not sure how to proceed. I have read that with OS X newer than 10.5 I should be able to do it via wifi, without having to use an installation disk...?

Repair HD with original Installation disks

Help, I ran Disk Utility on my startup disk (iMac HD) to be advised it was corrupt and I need to start up my iMac with another disk (such as your mac os x installation disk) and then use the disk utility to repair the disk.
My original os x installation disks (2 off that came with imac at purchase) are for os x 10.4.10 - I am currently using os x 10.6.8. If I do the above with the 10.4.10 disks will it change my os x level back to 10.4.10 or just use it to repair the HD and leave 10.6.8 and my data as is?
I'm doing this as my imac has slowed considerably for all apps and stating up - my best guesss is this corrupted startup HD is a major contributing factor.
Can anyone advise if I should go ahead and what the results will be.
Thanks.

You should be able to check and hopefully repair the drive with grey Disk 1 that came with the Mac. This doesn't alter the version of OSX you have installed.
Although you hopefully won't need it do you have backup you can restore from if it turns out the disk is unrepairable?
Restart with grey Disk 1 in the drive whilst holding down the 'c' key. (You're not going to re-install the OS) At the first screen choose your language, at the next scree, from the menu bar select Utilities>Disk Utility, select Macintosh HD on the left and click on 'repair disk'. If anything gets fixed/changed click on repair disk again until you get a clean pass. Restart as normal from the Apple menu.
A common cause of slowdowns seems to be caused by some anti-virus programs, Trusteer's Rapport (banking security software) and apps that claim to 'speed up. enhance, boost, etc. your Mac'. The worst offender seems to be MacKeeper - do you have any such software installed?
Also, lack of RAM can cause similar slowdowns - how much do you have installed?

Any way to repair disks without the installation CD?

I have the latest version of snow leopard and haven't used my laptop in awhile because I needed to get repairs done on it. Finally repaired it at the apple store, took it home, ran the updates, but disk utility is saying my drive is corrupted and to repair it with the installation disk. I have been looking everywhere and only found the TechTool deluxe CD but can't find my actual installation disks.
Anyone know how I would go about repairing my disk ?
Thank you in advance.

You need an installer disc or an external drive from which you can boot the computer. Otherwise you cn try:
File System Maint. - fsck
Boot into single-user mode. After startup is completed you will be in command line mode and should see a prompt with a cursor positioned after it. At the prompt enter the following then press RETURN:
/sbin/fsck -fy
If you receive a message that says "***** FILE SYSTEM WAS MODIFIED *****" then re-run the command until you receive a message that says "** The volume (name_of_volume) appears to be OK." If you re-run the command more than seven times and do not get the OK message, then the drive cannot be repaired this way. If you were successful then enter:
reboot
and press RETURN to restart the computer.

How do I do this: "This disk needs to be repaired. Start up your computer with another disk (such as your Mac OS X installation disc), and then use Disk Utility to repair this disk?"

"This disk needs to be repaired. Start up your computer with another disk (such as your Mac OS X installation disc), and then use Disk Utility to repair this disk."

Stick the disk in, reboot holding c.
Disk Utility is a menu option about the 2 or 3rd screen in the installer. (don't install OS X!)
Because your booted form the installer disk, you can repair the disk.
Quit and exit the installer and reboot.
If your drive is not repaired, make a note of all what it says, for Apple to use.
Reboot and get your files off to a external drive,
Take the note and your comptuer to Apple for a warranty/Apple care call, they will replace the drive.

The DVDs that came with your computer have got a special Mac OS X version that can only be used with your computer.
You have a Mid 2009 MacBook Pro that originally came with Mac OS X Leopard. As you upgraded to Snow Leopard, you can use the Snow Leopard DVD to reinstall OS X. If your computer already came with Snow Leopard, you can use the Snow Leopard retail DVD > http://store.apple.com/us/product/MC573Z/A/mac-os-x-106-snow-leopard
If you want the second OS X DVD too, call Apple to get replacement discs > http://support.apple.com/kb/HE57 They will send you the DVDs that came with the Mac

Must repair disk, can't find installation disks!

Hi,
My macpro 10.6.4 has been running slow (but correctly) so I downloaded onyx to do some maintenance work on it. unfortunately it found that there are problems on the startup disk and advised me to insert the installation disks, and press C while restarting. Then go to disk utility and repair disk. Unfortunately I cannot find the 10.6 disks, I can only lay me hands on the 10.4.7 disks. Will this work? Or should I just keep working with a faulty disk (I have time machine backups) and request replacement disks form apple (I have my receipt)...
Many thanks for any advice

Ah, the rule I would adhere to: never modify / download or install something on a drive that is in needs of repair.
Mac Pro: there is NO reason in that setup to not have a small emergency system volume, a good bootable clone backup.
Rule #2: never use older versions, even within the same OS family.
#3: pick up Disk Warrior; backup hard drive.
#4: Apple $29 Snow Leopard DVD 10.6
What you can use though is fsck, which is one part of Applejack (it has others like cache cleaning which is very useful), check for corrupt prefs and 3-4 other features. Snow Leopard Cache Cleaner is almost identical, they rely on Apple's command line diskutil / fsck from Single User Mode.
There is also Shift key and SAFE BOOT.
Depends on the severity of the error.

I would not download an app/utility in such a situation.
Running slow is not normal or healthy.
And I keep seeing problems lately from (a few) using Onyx, obviously with underlying problems to begin with.
Do a favor, invest in Disk Warrior and setup OS X on another drive.
Disk Utility RESTORE can copy your system to another hard drive and allow you to boot from there. Use that.
Make sure "Ignore Ownership" is not selected first (with internal drives, it wont but with USB/FW it usually is).
In future, SuperDuper or CCC can keep your backup clone current and up to date.
For now, DU Restore will give you another drive to boot from and use; and to repair your current system drive. But I would not put off getting Disk WArrior and a better maintenance and recovery procedure. Rather than waiting for slowdown or issues and focus on prevention.

27" iMac freezes, but mouse moves. 10.6.8. For 2 days, same error with volume info. Repaired disk from install disk twice.

Here's more info. Bought the iMac in Nov. 2009. It's been one with lots of problems, including a new mother board. Haven't had any big troubles lately until now. The exact error is:
Invalid volume file count
(It should be 888333 instead of 888334)
Invalid volume directory count
(Should be 221900 instead of 221899)
These were the only error messages. I did use Disk Utility to repair the disk, twice in two days.
2.66 GHz Intel Core i%
12 GB 1067 MHz DDR3
(219.55 GB available)
I'm not sure what else would be helpful to know.
Can someone tell me what's up, please?
Thanks! Jane

It would appear Disk Utility cannot repair the problem. This is not a big problem, but fixing it will require you to purchase and use Disk Warrior. Alternatively, you can backup your files, erase the drive, reinstall Snow Leopard, then restore your files.
Clean Install of Snow Leopard
Be sure to make a backup first because the following procedure will erase
the drive and everything on it.
     1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
         with your computer. Insert the disc into the optical drive and restart the computer.
         After the chime press and hold down the "C" key. Release the key when you see
         a small spinning gear appear below the dark gray Apple logo.
     2. After the installer loads select your language and click on the Continue
         button. When the menu bar appears select Disk Utility from the Utilities menu.
         After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
         size.) Click on the Partition tab in the DU main window. Set the number of
         partitions to one (1) from the Partitions drop down menu, click on Options button
         and select GUID, click on OK, then set the format type to MacOS Extended
         (Journaled, if supported), then click on the Apply button.
     3. When the formatting has completed quit DU and return to the installer. Proceed
         with the OS X installation and follow the directions included with the installer.
     4. When the installation has completed your computer will Restart into the Setup
         Assistant. Be sure you configure your initial admin account with the exact same
         username and password that you used on your old drive. After you finish Setup
         Assistant will complete the installation after which you will be running a fresh
         install of OS X. You can now begin the update process by opening Software
         Update and installing all recommended updates to bring your installation current.
Download and install Mac OS X 10.6.8 Update Combo v1.1.

No Disks that meet the citeria in the Solaris installer documentation found. Please check the system or try another installation option #

I'm tring to install this on an IBM netfinity 5100 server which has ultra 160 scsi drives.I get this message
"No Disks that meet the citeria in the Solaris installer documentation found. Please check the system or try another installation option #"
Please help me. I new to UNIX and SOLARIS.Thanks!

You are probably using the INSTALL CD that comes with Solaris x86.
Don't use it but use the Software CD 1/1 to boot and install the system instead. The INSTALL CD is supposed to be used on a completely blank system (no other OS's) although even there I think Software CD 1/1 does the job.
Also, if you are new to Solaris I advice you to get the FAQ (you can find it on e.g. http://www.science.uva.nl/pub/solaris/solaris2- it should be really helpfull during the first few weeks/months on Solaris

New Prpblem with Repairing disk

When one of my apps ( from an external HD ) wouldn't open, I ran Disc Utilty on this HD and got the following message:
*Repairing disk failed with error Could not unmount disk*
Can someone explain what this means, and suggest a course of action to remedy this ? Yesterday, I installed a new part to this programme, though I ran Disc Utilty afterwards and everything was OK, and i had the programme up and running without any problems.
Thanks, SeaDream

You were booted from the HD and repairing the external? Usually, when I get that message, I just try again and it unmounts. DU can't do repairs without the disc being unmounted. That's why the Repair button on the drive you're booted from will be dimmed and unavailable. Very crude medical analogy: like disconnecting your heart and trying to work on it without having another heart in its place to keep you alive.

Repairing Permissions with Disk Utility on PowerPC

I was just wanting to check this.
If I want to repair permissions on a powerpc G5, can I do this from the copy of disk utility installed on the machine or do I need to do it from the Start up disk.
I have unfortunately misplaced the install disk copy of leopard and was also having an issue with the copy I had being read on my superdrive.
I feel need to do a permissions repair to resolve some minor issues.
I have tried using Target Disk Mode with another Powerpc but this does not allow permissions repair but only disk repair.
Any clarification on this would be most helpful.

Thanks for your response.
I recall reading somewhere that such repairs had to be done from a separate disk which is why for years I have always done it in this manner.
So it turns out then that I can do this from the Disk Utility on the hard drive already, which makes life a lot easier.
Is there any procedure required to do this such as shutting down open applications or anything?

Is anyone else having problems with Verifying and Repairing Disk permissions?

Hey folks, every time I try to verify and repair disk permissions lately, this is all I get...
Verifying permissions for “Macintosh HD”Group differs on “Library/Printers/InstalledPrinters.plist”; should be 80; group is 0.Permissions differ on “Library/Printers/InstalledPrinters.plist”; should be -rw-rw-rw- ; they are -rw-r--r-- .Warning: SUID file “System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAg ent” has been modified and will not be repaired.
I usually get a long list, then repair it, and it seems to keep things clean.
I'm having trouble with my address book.
When I move the mouse down the bottom of the page my dock doesn't come up right away, sometimes it won't - I have to command tab to go to another program.
So I'm wondering if these are related. Thanks for any help!

Can't repair disk with Disk Utility

I had the spinning wheel of death on my G5 Imac so booted from instal disk and ran Disk Utility and got this message :-
First Aid failed
Disk utility stopped repairing disk 1 because the following error was encountered:
The underlying task reported failure on exit
In the list window when it got to checking catalog file I got
checking catalog file.
-Invalid sibling link
Rebuilding catalog B-tree.
-The volume disk could not be repaired
Error: The underlying task reported failure on exit
1 HFS volume checked
1 volume could not be repaired because of an error
Repair attempted on 1 volume
1 volume could not be repaired
Any suggestions? or is this the end of the road for my Hard Disk?
Would another disk repair program be able to repair this problem?
Thanks
John

Hi
I tried diskwarrior but but couldn't get to the rebuild directory page.
When I hit the agree button the screen goes grey with a spinning wheel then Imac reboots itself.
Tech support at D.warrior suggested resetting pram and open firmware but this makes no difference I'm awaiting further suggestions from them.
Any ideas here?
I ran a hardware test which showed nothing wrong.
Just read about target disk mode can link up and access my imac from my Ibook and repair the Imac with diskwarrior through the Ibook?

Repair permissions with disk utility

I have tried all the suggestions about permissions repair and have recently reinstalled the combo upgrade to x.5.2 twice. I am still unable to repair permissions with the disk utility. It stalls at one minute for 20 minutes and completes after at least an hour repeating the usual messages, as reported in other posts,

Another possibility... the first time I ran Disk Utility after the upgrade it ran easily for an hour before finishing. Now it takes a few minutes, with the usual "ACL found not found" garbage.
Try leaving your computer on overnight. Most of the Cocktail functions replicate the standard Mac clean up functions that occur in the early hours of the morning. The next day, restart, run Disk Utility - Verify. If that comes up clean, try Permissions again. Let it run until it finishes even if that is well over an hour. BTW... make sure that your machine is updated to 10.5.2, disconnect any external drives, USB or Firewire devices and make sure that there are no programs open. You may even have to check System Preferences>Accounts>Login Items to see if something is running in the background that can be temporarily turned off.

Problems after repairing disk with Mac OS X install Discs

Having been experiencing slowness in my iMac, I tried to verify disk and found that my HD Volume needed to be repaired. However, the "Repair Disk" button was gray. I later learned from online mac discussions that I should reboot my iMac with the Mac OSx install Disc. I followed the steps and then got the answer that there was nothing to be repaired.
The next thing I knew was that I could not get out of there. By choosing "Restart", I was bought back to choosing the language and installing the disc. Not wanting to do that I went around and around and finally had no choice but installing the Disc 1 and then 2. At one point, I was asked if I wanted to move previous files to the new location (don't remember the exact words), I said no. I was astonished to find out very soon that my computer was put back at its original state, meaning all the applications were empty.
I managed to get my safari and email (Microsoft Entourage) back. I transfered all photos from the "Previous System" folder to the present iPhoto. However, they are only sorted by year. all the categories and sub-categories that I so painstakingly created were gone, so were the keywords.
Among other problems, my iTune wouldn't open unless I have Mac OS X 10.4.9 (mine is 10.4.4). I am quite desperate at this moment. I know the previous settings are somewhere but have no idea how to bring them back.
I hope someone can help me get out of this mess. Thank in advance.
P.S. my iMac is much faster now. That is the only good news.

There is an option to +select the drive to restart from+ (don't remember the exact wording) in the Installer's menu. If you previously set the startup disk to be the disc in the optical drive, it will continue to restart from the Mac OS X installation disk until you change it. Alternately, you could press and hold the Option key at startup to bring up Startup Manager. This will allow you to select the disk to use for startup. For future reference...
If you did a complete reinstallation of the OS, you need to select Software Update from the Apple menu. This will get to you to the latest version of Tiger, which is 10.4.11.

Repair Disk from CD Installer?

Hi
I been having problem with my mac mini for a while now; stalling, not responding and quieting applications. Repairing permission don't help and the Repair Disk 'button' seem to inactive so I click Verify disk and it told me my disk is corrupted and need to repair disk from installer cd. That what I don't know how.
I had upgraded from Leopard to Snow Leopard last year. Which cd - leopard or snow leopard I should use and how to do it.
Please help. Thanks
JVale

Thomas. I thought I should answer your mentally ******** attack on my grandma (JVale). My grandma was truly thankful that you help her to do what she wanted to do and she did printed your Mac Backup Guide link from your ‘last’ reply for her to read later thinking she'll learn something useful from it.
But when my grandma answer The Hatter respond to her question and advising her to use Disk Warrior and SuperDuper and told him its too complicated for her as a ‘simple computer user’ and worried she may end up not be able to use her mac at all. You jump in and attack her to her reply to The Hatter. If she doesn’t want to use Disk Warrior and SuperDuper its her choice. Being old and still learning about her computer, of course, she won’t feel safe to try to do or use things that she don't know or understand. Why would she want to complicate things when she’s happy with her external drive and back up cd. And what is your right to attack her when her reply was not even for you - it for The Hatter????
My grandma (JVale) maybe a ‘simple computer user’ but for her age she did very well of keeping up with today's technology and not let herself left behind. She bought a mac computer and learn how to use it after someone told her apple computer is easy to learn to use for beginners. Now she’s happy that with her mac she could keep in touch with her relatives overseas through skype, yahoo messenger and yahoo mail and telling us all that we should change from pc to mac.
Why it offend you Thomas that my grandma is just a ‘simple computer user’?!! Tell me. Is your own grandparents or parents understand and can do what you could to computer. Of course, not. Its not their generation. DUMMY! Its a shame that with your superior brain never occur to you the possibility that maybe some of the member of the forum are simple computer user oldies who just want a simple solution to their mac problem. So. Who’s mentally disable now - or as you said yourself, the attitude just plain stinks. Yes. You are mentally disable and stinks! What you said TOTALLY APPLY TO YOU.
