Disc Utility warning

I hope im in the right place, I have iMac 2.4 GHz intel core 2 duo running 10.6.8. I have problems with iPhoto so a ran disc utility repair disc which put up the following
WARNING SUID file system/library/core has been modified and will not repair
I have no idea what that means but I have a feeling it has something to do with iPhoto being messed up. Any suggestions please but please keep replies simple this is way out of my comfort zone.
Mike.

Mike, it sounds like there's a problem with the drive, but most likely it has nothing to do with iPhoto per se. I'm guessing you ran Disk Utility directly without booting the Mac in Recovery Mode, or from an Apple OS install disk? In other words, you ran DI just from the Utilites folder? If that's the case, the issue is you can't repair a disk that is being used to run the system at the same time. There is a way round this though.
Hopefully, you still have the DVDs/CD's that came with the Mac? If so, you need to insert the OS install disk and restart, holding down the "C" key, then run Disk Utility again. Here's a page I found describing nicely what to do and what you'll see:

Disc Utility - warning if RAID HD fails ?

I would like to set up an external RAID1 in a Sonnet JBOD ( Fusion D400P ).
I just learnt, that if I set up this RAID1 with Apples Disc Utility, there will be no automatic warning if one of the drives is failing...
Is that true ?
Do I need to set up the RAID with SoftRaid to be on the safe side ?
Cheers - Steffen

I would try reinstalling.
Reinstall Lion, Mountain Lion, or Mavericks without erasing drive
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.
Repair
When the recovery menu appears select Disk Utility. 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 then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu. Select Restart from the Apple menu.
Reinstall Mountain Lion or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet
if possible because it is three times faster than wireless.

During a routine verify permissions using my disc utility, I'm getting a WARNING: SUID file "Systems/Library/CoreService-.ent" has been modified and will not be repaired.

During a routine verify permissions using my disc utility, I'm getting a WARNING: SUID file "Systems/Library/CoreService….ent" has been modified and will not be repaired. What does this mean?? I'm not awawre that I did anything to cause this and is it somethingI should try to fix?

1. It means that the current software is installed.
2. It's not something you should try to fix.
3. Verifying and repairing permissions shouldn't be done as routine tasks.

How do I break a mirrored Raid in disc utility?

I have two 2.5 TB LaCie Biggest S2S external drives that I mirrored using Apple's Disc Utility. Now I would like to break the raid to free up Drive B without compromising the data on Drive A.
I have been told I could just unplug Drive A, erase and reformat Drive B, then plug Drive A back in... but would appreciate to hear from someone who has done this before and can confirm this is the right way to go about it.
Many thanks.

Thanks. I would do that, but when I click Delete, it gives me a warning that says:
Deleting a RAID set will destroy all information on the all the disks of the RAID set.
Are you sure you wish to delete the RAID set?
This makes me nervous, as I can't afford to have all information on both disks destroyed. Are you saying it won't destroy my data on both disks?

How can you prevent encrypted folders that you created in disc utility from being deleted?

You cannot create encrypted folders in, or encrypt folders with, Disk Utility.
You can create with Disk Utility encrypted disk images from folders. I assume that's what you mean.
The proper way to do it is by setting the immutable bit. Read here
<http://www.thexlab.com/faqs/immutableflags.html>
about the immutable bits (and the trouble they sometimes create).
The user immutable bit (uchg) is the same as the Finder lock, as described above by X423424X. It's a weak lock, with only a warning.
The system immutable bit (schg) is more powerful. Once is set, the item cannot be deleted in Finder (even though Finder will ask for your password and may give you the impression that it can trash it; it will end with an error).
I set it in Terminal, thus
$ sudo chflags schg my_encrypted_disk_image
and unset it also in Terminal
$ sudo chflags noschg my_encrypted_disk_image
(Note that, when you unset the system immutable bit, the change won't be reflected immediately in Finder, but the item can be trashed nevertheless.)

Ive got an issue, i cant download a think because it says my disc space is all used.. ive only just bought this macbook.. i go to disc utility and there is macintosh HD at the top, it says i have no spece under that there is another saying ive usedon 39mb

ive got an issue, i cant download anything because it says my disc space is all used.. ive only just bought this macbook.. i go to disc utility and there is macintosh HD at the top, it says i have no spece, there is another available macintosh HD that i can click on and that tell me i have only used 39GB out of the 500. to make this abit more confusing, the one that tells me i have no space says its type says its a logical volume group, the other with space tells me the .

You've encrypted the boot volume with FileVault, so the reading in your first screenshot is normal. The reading in your last screenshot shows that you have plenty of disk space.
A false "disk full" warning can result from moving a Safari download between folder while it's in progress. Is that what you did?

Interrupting Disc Utility 8x overwriting

Hey There,
I want to erase my drive and stick my G5 iMac on eBay. I did the disk utility thing, and chose 8 times write over. It's been running round the clock for 4 days, and it isn't even halfway. I'd like to quit and ask it to do a few passes manually.
My problem is that when I got to quit the utility, it gives me a message saying if I quit, it could render the drive useless. Since I intend to reinstall OS X as a clean install, does it matter? That is: would you quit at this point, or let it complete it's cycle?
Heeeeelp!

You are absolutely correct!
*ATTENTION APPLE AND USERS*
DO NOT SELECT the overwrite 8x feature. Now that I've tried it, there are two reasons, the second of which is CRITICAL if you value your LCD screen.
1. For some reason, it takes longer than if you did single overwrites manually. On my iMac, it takes about two hours to do one sweep of a 160GB drive. So, times 8, that should have 16 hours or so. I had it running for 5 days, round the clock, and it barely made it halfway. I believe the 8 times does random stuff, where the 1 times does zeros, but still... something's wrong there. But worse:
2. If you choose the 8 times, it will mess up your LCD. How? Understand, you're running this disc from a CD. The CD isn't OS X, and so it doesn't dim while it works. So if you leave the LCD on for 5 days as I did, and leave the Disc Utility window in one place, *it burns in an image*. Luckily, it's faint, and only appears to have burned in the shadow effect applied to the window. Still, this may be grounds for asking for an LCD replacement, since there's no warning from Apple of this eventuality.

I have an alert message in disc utility. Error: storage system verify or repair failed. Problems were found with the partitian map which might prevent booting.

While running verify disc in disc utility on 251 GB SSD SM256c Media I came up with this message: Alert system verify or repair failed. In the descriptions box of history it said, problems were found with the partitions map which might prevent booting. This is followed by a message in red reading, Error: Storage system verify or repair failed. At the time I was down loading raw pictures off my camera through a card reader across my computer to a relatively new 2TB Western Digital portable hard drive. after about 13 to 15 pictures downloaded that drive faileded. My Mac Book Air works fine, but i get this message now everytime I run disc verify on this disc. The Macintosh HD checks out fine.

My external HD will not show up on my desktop anymore. I'm on macbook pro 13", OS 10.7. It doesn't show up in disc utilities, nor on another mac, nor on that mac's disc utility. I happened to restart the comp while the HD was connected.

My external HD won't show up anymore on my desktop nor does it get listed in disc utilities. I tried to cennect it to another mac but it doesn't show there either nor in that mac's disc utility. I happened to re-start the computer while the hd was connected and now it doesn't show up anymore. I use it for back-up via Time machine. I could re-format and do the back up all over again but then I need to find it first. Please, does anyone have any solution to this problem?

It sounds as though the external drive may have failed. There's nothing at all wrong with restarting your computer with the external drive connected -- that's a perfectly reasonable and normal thing to do, done by countless users every day without any ill effects.

Trying to install snow leopard on my Macbook Pro. After already having problems with Grey screen, blinking file with a question mark, etc. Computer now says that one of the hard drives is failing.The "hitachi" drive says it's failing in disc utility.

o.k. So, I've been tinkering with several "self help" fixes for several days now with no positive results. I'll explain my initial problems and then end with my most current situation. In hopes that someone out there will have a good suggestion or possibly remedy for the issues i'm facing
First, my problem started after my wife played a game on my macbook pro and the computer froze. She went into a panic and decided to shut down via power button. When computer restarted she got the blinking file/grey screen and that problem continued for a couple of days before I began using steps from various support topics from apple concerning the grey screen/blinking file folder.
Ultimately, yesterday I decided to erase my Macintosh HD file as one tip suggested. Following the brief online and on screen (via the process) tips that were there. Once that was completed I attempted to reinstall snow leopard (my most current version on hand) into the pc.
At first, I thought this would work. It looked promising. But, after several hours the installation screen returned with failure. I attempted to repeat. And, even repair drives during this try and re-try process.
Now, today, one of the drives.. "hitachi..." states that it's failing and is in red letters with no ability to repair via the disc utility screen. The Macintosh HD drive shows that it's o.k. But, this drive is listed under the HItachi drive so I think that's where a problem might lay.
So, I guess my question really revolves around.. What if anything can I do to get the hitachi drive back up? (short of taking it to a repair facility and replacing.)
And, how on earth can i get my OSX back up to I have a laptop again.
Operating on a macbook pro here. It's my lifeline. Otherwise, I am using a Windows desktop that i'm not that fond of. lol
I'm trying to bring this 2006 laptop back to life. Trying to avoid a rather expensive repair or the purchase of a new laptop. Also expensive...
Any help would be appreciated.

Well, running on a 2006 model. I did not have a startup disc. Initially, it booted up on original software in 2006. Since then, I've upgraded to 10.6 via a box set. And, since then I think I popped it up to lion.
All I have on a disc is snow leopard. And, I can't get farther than the setup screen due to hard drive. I'm taking to a apple authorized repair store right now. We'll see what they tell me . I'm just going to weigh the cost of repair vs. buying new.
Another bad, stupid thing is I had no means of backing up my stuff. So, I might have lost things like music, vids, etc. we'll see if they can recover. If the cost is too much for repair I might just forget it and start over with a new system. Just not sure at this point.

Safari wont open; disc utility says errors on the drive but cant fix them

Hi, Safari isnt opening despite my installing it again from the CD as well as trying to install it from the latest version available online (I saved it onto my thumbdrive from another computer). So I ran disc utility and it says there are errors but that its not allowed to fix them since its mac HD that has the errors.
I couldnt copy and paste the log as it says 'not enough memory to complete the operation' but this is what the last bit said:
Volume bitmap needs minor repair check volume information. The volume MacintoshHD needs to be repaired.
Error: The underlying task reported failure on exit.
Additionally a lot of other applications: tech tool deluxe (from the apple protection plan CD), word etc. have been quitting for no reason. Is this a virus? Is there anything I can download to fix this?
Please help, I'm desperately trying to fnish my thesis on time...any suggestions would be hugely appreciated.
Thanks in advance.

Welcome to Apple Discussions
I ran disc utility and it says there are errors but that its not allowed to fix them since its mac HD that has the errors.
There are no viruses on your machine. Macs to date have not been affected by the typical viruses seen on PC's.
It seems you have directory errors on your Hard Drive. These can be caused by the machine shutting off unexpectedly (power failure), corrupted application code, or even lack of routine system maintenance.
You cannot correct directory errors on the same drive you are operating from - in this case your Hard Drive. In order to correct the errors, you need to start-up from your Installer DVD. Insert the disc. Once loaded, restart the computer. When the screen turns momentarily dark, hold down the C key. This tells the machine to start up from the DVD rather than the Hard Drive.
You can release the C key once you hear the CD engaged and the grey Apple screen appears. When fully installed, go to the Installer Menu and select "Disk Utility". When the Disk Utility panel appears, single-click on your Hard Drive on the left side. This will open the First Aid Panel. On the right you'll see "repair disk". Select it. Errors will appear during the process. Once done, continue to rerun until you get a clean pass.
Once finished, quit DU and quit the Installer. This will automatically restart the computer. From here, the log-in screen ought to appear and ultimately your Desktop.
When complete, go to the Utilities folder and select "disk utility". Again, highlight your hard drive. In the first-aid panel on the left select "repair permissions." This will not take very long. Refrain from using the computer while it is running.
Post back with results - there is more to do.

Archive and Install/Disc Utility issues -

I'm currently spending a summer abroad in South America, and have had issues with my Macbook Pro (early 2011 version) no longer starting up after some virus experiences last week. The computer hangs itself during loading on the white screen w/ grey apple and the spinning dial. In contacts with Apple Care as well as some Mac-saavy friends, the following situations have been tried:
Opening in safe mode - The loading bar (added at the bottom of the grey apple screen) loads about 1/4 of the way, disappears, and the computer hangs itself.
Opening in single user mode - I run the recommended sbin/fsck -fy command to clean up the hard drive. It comes back after having checked 6-7 parts, saying that the MacHD is in good shape, with a message following saying that something had been "modified" (forgive me for not remembering the correct verbage at present). I then run the same command again, resulting in a message that the HD is clean and without error. I then "reboot" and remain hung on the white screen w/ grey apple.
Opening in verbose mode - I reach the following lines of text, and then there is no further progress:
enable
IONetworkController::enable
createMediumTables
enable end
MacAuthEvent en0   Auth result for: 00:23:cd:1e:f2:c4 No Ack
same line as above saying "Auth timed out" at the end
Command+option+r+p - shock two or three times, (three startup chimes) and computer continues to hang itself in the normal spot.
- So, at this point I took the advice of Apple Care and a few other friends, and tracked down a "retail copy" of Mac OSX (10.6.3) in order to try to do an Archive and Install or any sort of Disc Utility via the startup disc.
Inserting the disc and holding "c" at startup results in the cd drive whirring the disc for a few moments, and then remaining hung at the same white loading screen.
Holding "option" during the startup gives me the option of loading from the HD, or the disc. Selecting the disc proceeds to whirr the cd drive, take me to the white loading screen with the grey apple, and... you guessed it... leaves the CPU hung.
My question is then, is my Macbook Pro unable to read this disc and execute Archive and Install/Disc Utility for hardware reasons as per the virus attack, or is the disc not compatible with my version of OSX (which I have since confirmed through my wife to be 10.6.6)?
Different sources have told me different things. The local AASP in Uruguay sold me what they professed to be the "latest" version of OSX - the 10.6.3, what's more for $55 dollars instead of the lower cost as available in the states (between $15-$30), so I am reluctant to go back to them for advice when they seem more inclined to cash in on my inexperience (Mac owner of less than a month) than actually fixing my issue. Apple Care told me that a standard "retail disc" should work, but I am assuming now that they believe I can snag the same version as initially came with my Macbook Pro. Should I be looking to have my wife mail my original OSX install DVDs down here to resolve this problem? Should 10.6.3-retail be working and is not for reasons I haven't identified? I have since done some online research and found mentions that doing any sort of HD partitioning or OSX reinstalls can only be accomplished by utilizing a disc of an equal or more recent version of the OSX (examples that 10.4 can't work on a notebook preinstalled with 10.5, etc). Does this translate to 10.6.3 not being able to function for my 10.6.6 MBP?
Any insight or thoughts would be much appreciated, as essentially all of my schoolwork and assignments are now trapped on an inaccessible HD. Thank you for your time.

I tried adding in a bunch of information about what your troubleshooting steps meant, but the server went into maintenance while I did. So, here it is again:
"Opening in safe mode - The loading bar (added at the bottom of the grey apple screen) loads about 1/4 of the way, disappears, and the computer hangs itself."
     This is FSCK running, and gives you an indication of it's progress.
"MacAuthEvent en0   Auth result for: 00:23:cd:1e:f2:c4 No Ack"
     This is either a failed DHCP request or ARP request.
"Command+option+r+p"
     Command+Option+P+R - Resets PRAM. That's why p+r.
"Inserting the disc and holding "c" at startup results in the cd drive whirring the disc for a few moments, and then remaining hung at the same white loading screen."
     This problem indicates that the disc is too old to boot your system. The reason for why this disc cannot boot is because it doesn't contain the necessary drivers for your model MacBook Pro. My mom and brother have similar models, and my brother had similar issues while in Japan. He went and got an install disc as well, which failed, I ended up stepping him through so that it would boot in Safe Mode, and then got it working in Normal Mode remotely.
FYI: Sophos has a free Mac Antivirus program, that is very processing friendly, and will scan in the background. You may wish to consider it as an alternative to Avast! if it continues giving you problems. Though I suspect it may be coincidence that your computer had problems shortly after Avast! cleaned up files. Let me know how it goes. You may wish to open up Disk Utility and check your S.M.A.R.T. Status. You want to make sure it says "Verified" If it doesn't say "Verified" then you have a problem.
