Disk Repair Concern

Hello,should any of this be of concern after running "Verify Disk Permissions"I then Repair Disk Permissions and Verify Disk says seems to be o.k. but is it really?
Warning: SUID file "System/Library/CoreServices/Finder.app/Contents/Resources/OwnerGroupTool" has been modified and will not be repaired.
Permissions differ on "private/var/spool/cups/cache/rss", should be drwxr-xr-x , they are drwxrwxr-x .
Group differs on "private/etc/cups", should be 0, group is 26.
ACL found but not expected on "private/var/root".
ACL found but not expected on "private/var/root/Library".
ACL found but not expected on "private/var/root/Library/Preferences".
Thanks and HAPPY HOLIDAYS!

No. These are well-known messages that are completely innocuous. There's nothing to worry about.
See Mac OS X 10.5- Disk Utility's Repair Disk Permissions reports issues with SUID files.
ACL errors may occur if you've upgraded from Tiger to Leopard using the Upgrade Install option or if a particular program has used the older Tiger method of assigning permissions instead of the newer method used in Leopard.

Disk Utility, Verify Disk & Repair Disk unavailable

Hi there!
I want to check my Hard Disk with Disk Utility, but none of the two buttons (Verify Disk & Repair Disk) are available, I started up from my Mac OS X installation disc, and once, it told me that the disk had errors and needed to backup my files, so I went back and backed up with Time Machine, then out of curiosity went again and I started up from my Mac OS X installation disc, and this time it told me that the disk was fine and there wasn't any errors, but when I open Disk Utility with my Mac, none of the buttons are available, is this normal?
What should I do?
Context: Before all this, I installed a program called Tuxera to create a NTFS partition but my Mac started to act weird, so I deactivate and uninstalled this program, that's when I went to verify the disk.
Any Help would be gratefully appreciated

I hope I'm wrong but it sounds very much like Tuxera did something to your startup disk. I would also be somewhat concerned about the integrity of any Time Machine Backups you made after you ran Tuxera.
The safest thing to do would be to start up from your Snow Leopard disk and see if you can *restore your system and data from your Time Machine backups to an +external HD+* formatted using Mac OS Extended (Journaled) and GUID Partitioning. Formatting will erase all the data on that disk. *If you try to restore to the internal and it doesn't work you will probably lose most of your data.*
Startup your Mac using the external and check very carefully to see that you have all your data and that everything works as it should. If it does you can safely reformat your internal drive from Disk Utility on the Leopard disk using Mac OS Extended (Journaled) and GUID Partitioning. After that you can clone the external drive to your Mac's internal drive or install from the Time Machine backups.
If the Time Machine backup doesn't work you will need to run a disk data recovery utility to see if you can salvage your data from your internal drive.
I don't use PC's so someone may be along with much better advice. However, unless and until someone more knowledgeable about PC file formats comes along to help *don't reformat your internal drive until you know your Time Machine backups are OK.*

Repair Disk / Repair Permissions -- which first

If I want to run repair permissions or repair disk, which should I do first?
Does it matter?

"Repair disk" makes modifications to the structure of data on the disk itself. If there is an error, this really needs to be done first since the errors could manifest themselves as botched permissions, mangled files, etc. If the disk's integrity is actually compromised, the highest priority is to repair it. One thing to keep in mind is that certain repairs cannot be made on a mounted disk (such as the one you boot from), so for the disk repair procedure to work, you should boot of another disk (your OS installation disk, a bootable external hard disk, etc.). Even then, Apple's disk repair is curiously basic -- there's many errors it simply does not detect or fix and for that you need something like DiskWarrior. Mind you, disk errors like that shouldn't occur, and if they do you may have hardware issues to be concerned about.
"Repair permissions" compares file ownership and permissions in a directory to a list stored in the package bundles in /Library/Receipts. If there's a difference between what it finds in the file list stored in the receipt package, and the files on disk, it attempts to set the permissions and ownership of the file to what appears in the list (which should reflect the state of the file when installed). It doesn't do anything at all to preferences, user preferences, user files, logs, file created after and application is installed, etc.
Contrary to popular belief, repairing permissions doesn't generally do much for you. It should be pretty rare that it finds a difference unless you've really been mucking about, and generally when it does find something it's either because you explicitly changed the permissions or because there's some other problem where an application or disk issue is changing the permissions. The one time where it really makes sense, actually, is after you repair a disk issue.
It's common advice that people tell you to repair permissions as a step to address problems, but mostly because it's an easy thing to do. Similarly, zapping your PRAM is frequently advised when trouble-shooting, though the process of a cold-boot (complete power-off, then power back on a few seconds later) is generally the portion of that procedure that actually produces the desired result.

Unsuccessful install - HD Disk Repair - what's the safe/smart way?

Thank you in advance.
I'm trying to update my OS from Leopard to Snow Leopard, but the install is unsuccessful. I have an intel based iMac on which I initially used Tiger and then upgraded to Leopard without any trouble. In the Snow Leopard installation instructions, I read that I should try a few hard drive maintenance measures, but none of those have led to a successful update. Upon trying to verify the disk, Disk Utility reports that the disk does need repair, which is the next troubleshooting step according to the Snow Leopard install guide. Apparently, I can only do so by booting up the computer off an OS installation disc. Naturally, this is a bit disconcerting because I am under the impression that when I repair the disk, it will wipe my hard drive clean; thus, I will have to restore all of my hard drive from a backup or some sort of copy of my iMac hard drive. Unfortunately, I do not fully understand what actually occurs in a hard disk repair and what the potential ramifications are nor do I fully understand what a hard drive restore or re-copying it back to my computer does.
My goal is to update the OS to Snow Leopard so that CS4 is compatible with my computer. Also, I have had trouble using Canon codecs in Final Cut Pro; in fact, I can't even transcode them using the log and transfer option, and I read that an OS update to Snow Leopard may fix the issue. Of course, my ideal scenario is to update the OS while maintaining or easily restoring/copying my iMac Hard Drive volume back to my computer with the updated OS, without having to reinstall apps/software or even redoing all of my preferences or the setup, settings and shortcuts on my desktop and dock. Is this possible? Do you have any suggestions for a better way to go about all of this?
Here are some of my concerns more specifically:
Ordinarily, I try to backup my iMac Hard Drive with QRecall to an external hard drive regularly, but I have never actually had to restore any of the content, thankfully. For the purposes of what I am trying to do, would it be more sensible to just do a drag and drop copy of the iMac Hard Drive volume to an external and then back to the iMac after repairing the iMac hard drive disk and updating the OS or is it smarter to restore from the QRecall archive?
Assuming the hard drive disk repair solves the problem, when should I update the OS, before or after restoring my iMac hard drive? Or is the OS update something that I will do during the iMac hard drive disk repair?
Maybe this is a stupid question, but when I restore or copy (not sure of proper terminology) my current iMac Hard Drive Volume back to my computer, is the old OS not a part of that? Is it possible that I'd update the OS, then restore or copy the hard drive volume back to the computer, and then it would revert back to the older OS Leopard?
Again, thank you very much.

I am under the impression that when I repair the disk, it will wipe my hard drive clean;
That is an incorrect assumption. A disk repair will not erase the hard drive. See:
http://support.apple.com/kb/HT1782
It may, however, be the case that Disk Utility cannot repair the drive catalog. If that occurs, you can try a third-party disk repair tool - Alsoft's Disk Warrior is the one most often recommended - and if that fails then you will have to erase or, if erasing fails, replace the hard drive.
My goal is to update the OS to Snow Leopard so that CS4 is compatible with my computer.
Snow Leopard is not necessary for CS4 compatibility. CS4 predates Snow Leopard by quite a while and is and always has been compatible with 10.5 Leopard. CS5 is necessary for full Snow Leopard support.
would it be more sensible to just do a drag and drop copy of the iMac Hard Drive volume to an external
You cannot do a drag-and-drop backup of your hard drive. There are many hidden files and linkages that would not be copied.
when I restore or copy (not sure of proper terminology) my current iMac Hard Drive Volume back to my computer, is the old OS not a part of that?
Your backup has whatever OS version was on your computer when you made the backup. So if you restore that backup (assuming you backed up the entire drive and restore that same entire drive), you'll be going back to that version of Mac OS X.
I'm complete unclear on when you've made a backup and what got backed up, so without more information I can't say the steps I would take in your situation. Post back with details on your backup and we'll go from there.
Regards.

Disk repair failed / should I reformat my drive / how to format and restore

I have a MacBook Pro late 2011 model and upgraded to Yosemite. The performance on my MB is ok, but just out of curiousity I ran a disk verify, and was told I needed to reboot, hold down CMD / R and run disk repair. I did so and the repair failed. I was promoted to backup and reformat/restore.
Now, I do backup everything using time machine (not sure though if Parallels image is backed up). I do not however have any install disks for Mac OS.
My questions:
1. Should I even bother reformatting my HD?
2. How do I go about formatting the HD and then re-installing the OS and all of my apps, particularly given that I have no DVD
Any thoughts are appreciated. Thank you

If you have extra external HDD, make clone backup with Carbon Copy Cloner or SuperDuper!, then,
1) boot from external clone backup drive.
2) reformat internal HDD.
3) restore from clone backup drive with Carbon Copy Cloner or SuperDuper!.

Disk repair and startup\dvd drive issues

i'm running 10.6 on a 2ghz macpro - disk repair has found problems on the startup disk. i know i need to boot from another disc to repair the system drive, but i'm having problems doing so.
the dvd drive won't startup from either my original installation discs (tiger) nor my snow leopard dvd. restarting and pressing 'C' does nothing, then the tray opens and the mac starts from my HD.
I have a superduper backup on an internal drive, i can start from this but disk utility won't allow the repair of the main HD, saying it can't unmount it. I'm sure i've done yhis before by creating a temporary admin account and running dick utility from there, but even this isn't working this time.

First, under no circumstances should you try to use a Tiger install disk to repair problems on a Snow Leopard system. You need to use a Snow Leopard disk.
Second, make sure that you are using the disk that you used to install SL on the Mac Pro. It must be a disk that has a system newer or equal to the one that shipped with your machine. If your machine originally shipped with Tiger, but is currently running Snow Leopard, then any retail Snow Leopard disk should be able to boot the machine.
If the machine won't boot from a legit disk that it should be able to boot from, then either the disk itself is damaged or you have a hardware problem. Or, very rarely (I've only ever heard one first-hand report of such a thing), you could have such a severely-corrupted hard drive that it actually prevents you from booting from anything.
Are you able to load DVDs in your machine at all? What happens if you put in the SL disk when the machine is booted from another drive? Are you able to boot into [Apple Hardware Test|http://support.apple.com/kb/HT1509]? If so, run the extended tests.
I'm not sure why you'd be unable to repair the drive when booted from a backup on a different internal drive. Does that backup drive have the same version of the OS? Are you running Disk Utility from the backup drive or from the drive you're trying to repair?
You could try booting into single-user mode (hold down command-s at startup), then type "fsck -fy" at the command line. When fsck is done, run it again. Continue until either no problems are found or until you're reasonably sure it'll never manage to fix them all.
You could also try getting a copy of [DiskWarrior|http://www.alsoft.com/DiskWarrior/index.html] or [TechTool Pro|http://www.micromat.com>, which can fix some things that Disk Utility can't.

Trying to do Disk Repair but get beeping.

I need to do a Disk Repair through the Disk Utility function off my Snow Leopard Installation disc. However, once my Macbook Pro restarts, it won't take me to the OSX installation window. Instead, I remain stuck at the startup grey Apple screen, and get 3 beeps repeatedly. These beeps have only happened when I try to open the Installation disc. It has never happened to me when I turn on my computer normally without the installation disc.
I've also noticed that my laptop will randomly freeze sometimes with a spinning cursor when I barely even have an internet window open, no other applications running. I don't know if this problem is related to the issue above.
This is a 2011 model. Don't know if these specs will help at all (total tech newb here).
Processor: 2.2 GHz Intel Core i7
Memory: 4GB 1333 MHz DDR3
Any suggestions are greatly appreciated!

1) 3 long tones, 3 short tones, 3 long tones = Firmware restoration from CD in process.
2) 3 successive tones, a 5-second pause, 3 successive tones = RAM does not pass data integrity check
Which one?

Need disk repair help fast!

My internal CD drive broke so I bought an external one. Problem is that the computer is in need of serious Norton repair and when using the Sony external CD/DVD drive to run the Norton disk the computer does not recognize the hard drive so I can't repair anything. In other words, I put in the Norton cd and it shows up just fine on the desktop but when Norton opens up and I am supposed to choose a disk to repair nothing shows up to choose from. Nothing at all, just a big blank space. The external drive works because I've burned from it although when I try to burn directly from, say iTunes, it goes to the origional disk drive which is broken so I have to use the toast light program to burn. Maybe there is someway I can make my external drive the default one? It is taking forever to load each program and I'm feeling doom with the way the computer has been acting lately and I really can't afford to be without it as I run my business from it. thanks

Hi again, Donna,
Happy to hear you got rid of Norton!
You say your Mac has not panicked since you got rid of Norton, right? If so, you may have already fixed the kernel panic problem. I have not had a single kernel panic since I uninstalled Norton years ago.
If you do experience another kernel panic, the advice about kernel panics that you got from mrtotes is about the best that most Mac users can do for themselves. As explained in those suggestions, kernel panics are often hardware related. Be sure to disconnect all external devices that are not absolutely necessary when checking for and attempting to solve kernel panics.
You should not need to take your Mac to an Apple Service Technician for kernel panics if you can fix it yourself with the advice you have already been given.
<hr width="85%">
Next issue: You mention that your Mac runs slow (the beach ball spins for a long time.)
If you multiple applications running, close all but one and see if the problem goes away. If so, you may just be working your Mac too hard. Run fewer apps at a time.
If you have any external devices, including your external CD/DVD drive, connected, unhook them all and check to see if the beach ball goes away. If so, one or more of your devices may be the source of the problem. You can find which by reconnecting only one at a time and then checking to find whether the beach ball comes back. If no one device causes the beach-ball to reappear, try connecting two at once to see if any of your external devices might be conflicting with each other.
Your Mac may need basic Mac OS X maintenance. You have already done a Safe Boot, (and perhaps a disk repair), so try a permissions repair next.
Unless you have set the slider for your computer to "Never" sleep in System Preferences > Energy Saver > Sleep, you should also force background maintenance tasks as explained in
http://docs.info.apple.com/article.html?artnum=107388
The article lists several equally effective ways you can do this, I personally use MacJanitor, which is free and very simple to use.
FileVault slows disk operation and adds processor tasks to your Mac. If you have enabled FileVault, turn it off (turning FileVault off can take a while) to see if your beach-ball problem goes away.
One other thing that can cause slow (beach-ball) operation is that your startup disk may be too full. Check free (Available) space with Finder > File > Get Info. If you do not have at least 10 GB of free space, try Increasing available space on your hard disk.
For more comprehensive suggestions on OS X Maintenance, see Gulliver's

Disk repair utility & printer issue

I will admit right now that until last night, have never touched an iMac but I have a friend that due to health issues, needs a hand. Can I ask a couple of questions of this forum?
1: She has an external Lacie H/D that is making wierd noises after being knocked over. Her backup software says to run the Disk Repair Utility. I haven't the slightest idea where to find this Disk Repair Utility, nor if I can run it on an external drive.
2: Her printer, mac book and iMac were recently moved from one location to another home. I need her printer connected wirelessly to both computers. I was able to get her Macbook connected but I am having issues with iMac. Can I uninstall her printer and reinstall? Not even sure how to do that basic process so advice would be appreciated.

Disk Utility should be able to check the LaCie - whether it will be able to complete any repairs that may be needed will become obvious when it's attempted. Disk Utility is normally in the Utilities folder within the Applications folder.
Regarding the printer, yes you can uninstall it in System Preferences>Printers & Scanners (or similar wording depending on version of OS X). The +/- buttons add/remove printers.
If you still have problems, post back.

After getting the dreaded gray/blue screen, I tried to run disk repair on the internal disk. I got an error message saying "Disk Utility can't repair this disk and restore your backed-up files. The volume Macintosh HD could not be verified completely

After getting the dreaded gray/blue screen, I tried to run disk repair on the internal disk. I got an error message saying "Disk Utility can't repair this disk and restore your backed-up files. The volume Macintosh HD could not be verified completely." What do I do now? This is an iMac and I'm running 10.6.8.

Clean Install of Snow Leopard
Be sure to make a backup first because the following procedure will erase
the drive and everything on it. See below for how to clone a drive.
     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.
You may be able to backup your data if you have an erased external drive you can use. Before you do the above but after you have opened Disk Utility you can try to clone your drive:
Clone using Restore Option of Disk Utility
1. Open Disk Utility.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Select the destination volume from the left side list and drag
       it to the Destination entry field.
5. Select the source volume from the left side list and drag it to
      the Source entry field.
6. Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal startup drive.
Now this will only work if the drive is accessible and can be cloned by Disk Utility. Otherwise, you would need to access your drive from another Mac that you can connect via Firewire - Target Disk Mode.

External hard drive won't mount, even after disk repair.

My Toshiba external hard drive won't mount on my MacBook Pro 10.8.5. I can see it in my disk repair, and when I repair, "the partition map appears to be ok." But I can't access the icon to be able to open the hard drive contents on my desktop. Help!

Hello maccynicwhoalwayshasmacs,
Thanks for the question. After reviewing your post, it sounds like trouble with an external HD mounting. I would recommend that you read this article, it may be able to help you resolve or isolate the issue.

Recovery HD disk repair failed

Thanks

Disk Utility in recovery partition...: Apple Support Communities

Disk repair 'failed'

when i tried to repair my internal HD, disk repair fails. it found out that 'Reserved fields in the catalog record have incorrect data' do I need to format the drive and reinstall 10.4.11, or can this be fixed?

You could do that, but a simple reformat may not fix the low-level
issue that may exist on the hard disk drive; while a zero-overwrite
option Disk Utility provides may help, & also will defragment HDDs.
Of course, there is a chance a third-party disk utility could be able
to attempt and be successful in a repair where the native OS X
Disk Utility may not be fully adapted to these kinds of cures. For
some kinds of issues, Disk Warrior has been proven worthwhile;
so has (in some instances) Drive Genius, and TechTool Pro. The
version of these third-party disk tools has to match and be made
for the OS X version the repair is being done on.
There are times where a third party disk utility may make the
matter worse, so you have to really be ready and it does help
to have previous experience with the tools & how they work.
A crash course is never an expected way to learn, it happens.
If the computer is getting old, you may end up replacing the
hard disk drive, as they do wear out and work hard in a
portable computer. The cost per GB has come way down.
There are times when a hard disk drive is not readable and
the computer won't start from it, yet data may be recovered
from it in a few ways; one of them is FireWire Target Disk
Mode. Another may be to put the failed disk in an external
enclosure and attempt a repair at a later time, and have a
good hard disk drive in your computer.
If you backup your computer's contents and get comfortable
in making clones and using utilities, that is a good path to know.
In any event...
Good luck & happy computing!

Disk repair what do I do?

Ok my iMac is not even a week old and I'm seeing this...
What do I do?!
I hear your supposed to put the Mac OS X Install disk and hold "C" on a restart
but what happens when I do that I don't want any data to be deleted
and I don't have a back-up drive yet to back things up if something goes wrong. Will a disk repair erase data?
20 inch 2.16 Intel Core 2 Duo Mac OS X (10.4.10) 2 Gb or Ram

Hi
AFAIK, Disk Repair does not erase data so it should be safe to do it. When you restart from the install disk, choose the language & go to the next screen. A menu bar will appear, choose Utilities>Disk Utility. Select your disk (not the indented partition name (think that's right)) & click Repair Disk. Repeat this until no errors. If this doesn't fix it then you may need 1 of these 2 programs
TechTool Pro
DiskWarrior
It it always a good idea to have a backup, there are many posts regarding cloning/backing up your HD.

Disk Repair For A DYI Fusion

About 4 months ago I purchased a solid state drive and installed it with a regular drive (installed where the optical drive was originally located) in a Macbook Pro OS 10.8.4, 2.8 ghz i7 Core. I followed directions provided by Other World Computing and created a fusion drive using the two disks. Everything has been working great and the fusion is smokin fast.
Prior to the fusion installation I always ran the disk utility or disk warror to look for little glitches on my drive. The issue is when I boot from the recovery disk or a usb startup the two drives are shown seperately rather than one fusion drive.
So the question is can I run disk repair on each of the disks seperately without harming my fusion setup, or is there some other way to have a repair utility to recogonize the fusion set up on the two disks.
I am not having major issues but in the past found that doing a check like this can be helpful.

Have you updated DiskWarrior to 4.4? According to the Alsoft site, it as compatible with Fusion Drives:
