Massive stability issues - Disk Utility repair failed, hardware test failed

Hi,
I am having massive stability issues. The installer will not install anything, programs are quitting randomly, and it is getting very annoying!
I read through a lot of posts and I have attempted to:
Repair my disk using the install cd: but that failed.
I did a Hardware test: but i had an error relating to fonts (?), couldn't see anything on the screen and I couldn't do anything.
Is there something else I could do that I haven't tried?
I have had my PB for a little over a year and have had no issues like this before. All of these issues seemed to start when I was playing a game and it suddenly just quit; I then couldn't go back into the game or re-install the game.
Help!!

Hi, Dan.
You wrote: "Repair my disk using the install cd: but that failed."That's a big problem. You won't get very far until the problems noted by Repair Disk, the function I presume you ran based on your description, are sorted out. It's possible the hard drive has failed.
If the Apple Hardware Test failed, that's another significant problem. If it produces messages you can read that describe the failure, write them down. The machine may need to be serviced by an Apple Authorized Service Provider.
As to your next steps, first run the procedure specified in my "Resolving Disk, Permission, and Cache Corruption" FAQ. Perform the steps therein in the order specified to see what's up with your disk and if anything can be done to correct that.
Good luck!

Disk Utility: "Repairing disk failed with error Could not unmount disk"

Disk Utility: “Repairing disk failed with error Could not unmount disk”
Hi. I’ve been experiencing some mildly squirrelly behaviour with my system (vide infra) so decided to repair the two internal hard drives on my computer. The primary hard drive is a 74.53 GB ST380013AS that came with the system; its S.M.A.R.T. Status is “verified” and Disk Utility repairs permissions just fine. However, the second internal drive (Maxtor 6L250S0, 233.76 GB, lower Bay, Journaled HFS+), despite being verified by S.M.A.R.T. status and apparently running OK, fails to unmount when I ask Disk Utility to repair it- I get the above error message in red. I have repaired this disk with DiskWarrior (v3.03) and all appears to run AOK. Can anyone tell me why I cannot get Disk Utility to run on this secondary (eg, non-startup) disk? I have tried many times and the error is reproducible. Thank you!
G5 1.6GHz PPC, 1 GB RAM, running OS 10.4.6

Thank you for these useful links!
For others who have this issue, I also found very helpful advice given to this question on the MacFixIt forums by MicroMat Tech3 at
http://www.macfixitforums.com/php/showthreaded.php?Cat=&Board=tiger&Number=76265 1
He said: "Use the lsof command to find the open files on a volume that does not unmount or eject. Open Terminal, located in /Applications/Utilities. Type: sudo lsof | grep Leave a space after the p in grep, then drag the icon of the problem volume to the Terminal window. The pathname for the volume is pasted in for you; press Return. Then enter your administrative password at the prompt, and press Return."
At this point, one now has a list of the open files/processes on the volume that will not unmount. You can use Activity Monitor to terminate these processes if you wish, and then the volume will unmount as it should.

My Mac OS Lion 10.7 FileVaulted HD does not boot, prohibitory sign, stop sign appears some minutes after boot starts. Disk Utility repair shows four error messages:
Unable to bootstrap transaction group 2517: inconsistent crosscheck
No valid commit checkpoint found
The volume xxxxxxxxxxxxxx(here it shows physical volume number) was found corrupt and can not be repaired.
Problems were encountered during repair of the partition map
Error: Storage system verify or repair failed.
(the same with 2518, 2519 and 2520 transaction group)
I suppose it is serious bug in Mac OS Lion managing FileVault and wonder what the help could be?

Most likely culprit is your Lacie drives which are notorious for flaky power supplies which cause just the sort of erratic behaviour that you describe. Have had similar issues myself. Lacie has been good about replacing my power converter-- twice. If you have seven of them, good luck finding the bad one or more. Like I said, the behaviour is erratic. Sometimes it'll work sometimes not. I can't comment on Samsung drives because I've never used them and have never heard anything about them. Same with Softraid. Why not just use Disk Utility. Sounds like you're ready for an external hardware raid. This will be much faster, much more reliable, and may even be cheaper than seven firewire drives. Check out G Tech, and Maxx Digital for starters.
Best of luck

Disk Utility/Repair Help Please...

Hi
I have been having some issues with a Kernel Panic on my MBP. I am trying to solve them with the help of the X-Lab, but when I do the disk utility>repair permissions I get the following messages:
Repairing permissions for “Macintosh HD”
Warning: SUID file "System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAg ent" has been modified and will not be repaired.
Warning: SUID file "System/Library/PrivateFrameworks/DesktopServicesPriv.framework/Versions/A/Reso urces/Locum" has been modified and will not be repaired.
Permissions repair complete
Does anyone think this may be a contributory factor. If it is unlikely that these are not to do with the Kernel Panic, any ideas as to what they are and what I should do.
many thanks in advance
Rob

Those messages are normal and may be ignored.

Can Disk Utility repair FAT32?

hi, folks:
I'm jammed up. I need to repair the drive in my PS3. It's FAT32-formatted. Im a Mac user, obviously. Can Disk Utility repair it, or does it only do Mac discs?
Please say "yes" (and mean it!). (Barring, of course, hardware problems, I mean. I understand that if the platter is scratched or the controller's no good, I've had the radish.)

Grf. This wasn't the answer I wanted, but it's what I needed. Thanks, Kurt. I'm now off on a quest to find a Windows laptop. I appreciate the quick response.

ibook G4 - won't start up, spins, and shuts down... disk utility repair quits. says "invalid sibling link" "volume check failed" "1 volume could not be repaired because of an error" "the underlying task reported failure on exit"
any ideas about how to start and/or recover data ??
thanks

Hi chesterday, and a warm welcome to the forums!
You must repair the HD, your best bet is DiskWarrior from Alsoft...
http://www.alsoft.com/DiskWarrior/
You'll need the CD though.
Unfortunately, Disk Utility can't fix all that much, and the only other Apple Options are erasing the HD, or installing OSX to a second drive, then using Migration Assistant to move stuff over to the new HD.

Disk utility repair permissions stops altogether

I tried running Disk Utility Repair permissions and received a grey message box saying it stopped repairing permissions because of the following error:
Error: The underlying task reported failure on exit.
This same error message was repeated in the usual information box that disk utility uses to provide detail about what it is doing.
I believe the problem occurred because I selected Macintosh HD and added another user (myself) to read/write in the disk permission section of the information window, and I also applied that to all enclosed items. I did this in the first place because of repeated attempts and failuire to install the latest version of skype into my applications folder (being told that I didn't have enough permissions to complete the overwrite task). When I tried verifying the disk I received the error message "ERROR: could not freeze volume permissions denied"
I switched users to a specific administrator account that I reserve for troubleshooting, but got the same result when I tried running disk utility.
As a not unrelated issue when I attach my ipod touch, itunes says that it cannot recognize this ipod, then after about the third time simply doesn't acknowledge my itouch exists.
everything was working well until i did this large change permissions operation.
So does anyone have any idea what I have done (wrong) and how I can fix it?
thanks
John

Uh-oh. You completely trashed your whole system by doing that. Boot up from your Leopard DVD and restore that last Time Machine backup that was made before you made that mistake. If you don't have any backups you will have to reinstall Leopard.
I did this in the first place because of repeated attempts and failuire to install the latest version of skype into my applications folder (being told that I didn't have enough permissions to complete the overwrite task).
When that happens, just trash the old application first, then drag in the new one.

Changing permissions on the HD and applying to enclosed items hosed your whole system. That's what's causing all your problems. It's doubtful that you will be able to repair it. Restore your system from backup, or reinstall.

Disk Utility repairs permissions; 1 hour later they're un-repaired again.

(March 2009 24" iMac. Lion 10.7.3)
I repair permissions on Macitosh HD (boot volume) every-other week. I've noticed that the same permissions seem to need repair each time. Here are the last seven lines from the Disk Utility window from the May 19 run:
One hour later, I repeated the operation. Here are the last seven lines:
I might be overly sensitive, but I detect certain similarities between these results. In fact, it looks like Disk Utility repairs exactly the same permissions every time and those permissions are corrupted shortly after they are repaired.
What's going on here? Should I be alarmed? Or should I panic?

I'd like to delete this post (if I knew how). There are several other threads on this topic, and other contributors report exactly what I observe. It turns out it's a harmless artifact of upgrading from 10.5 to 10.6 to 10.7, rather than doing a clean install of Lion. This article is reassuring: http://support.apple.com/kb/TS1448
I shoulda searched more thoroughly before posting.

Massive stability issues. Firefox crashes often.

Ever since Firefox updated to the latest version, I've been having massive stability issues. I downgraded back to version 19, but it is still very unstable. I have to force-quit often when it becomes unresponsive - a dozen times a day or more.
Things I have tried:
- Updating all plugins.
- Scrubbing my registry.
- Clean install/reinstall.
- Deleting tracking cookies.
- Scanning for viruses and spyware.
- Downgrading to previous version.
I want to continue using Firefox, but this has gotten unbearable.

My MacBook Pro started running very slow. I did disk utility/repair

My MacBook Pro started running very slow. I did disk utility/repair and it helped but still very slow. Repair gave me this message, "SUID file 'System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAg ent has been modified and will not be repaired." Any suggestions on this message and/or what else I can do to get my computer back to the way it used to run? Thank you!

It says 199.15 GB free of 499.25 GB. Can I remove the Remote Management program to solve the other unrepairable problem?

V Ram failing Hardware test with error 2NVD/1/4:2122

Hello,
I have been using my Mac now for just over a year now, it was a wonderful birthday present last October. I have had zero problems until now.
Red wavey lines started to appear on the screen on and off for 2 - 3 minutes and then the Mac asked me to restart, after restarting the wavey red lines were constantly on the screen but it would not get to the login screen. I ran a hardware test which when reaching VRAM told me the above error code.
Does anyone know how this can be fixed at all? or had a simelar problem?
Thanks

Hi,
I'm sort of in the same situation as you. Purchased my powerbook last july. Has worked like a charm until the last few weeks. My mac suddenly froze while playing Warcraft 3. After shutting it down, and rebooting it, i would get this message telling me that i had to restart my computer (from what i found out, that message was kernel panic). I've also had all these little lines on my screen, and while i couldnt get to my login screen under a normal boot, i could safe boot it. I've tried everything i could think of, from doing a disk utility repair, up to re-installing OSX. I finally took it in to an apple service center, and that's what it was. The VRAM failed the hardware test. The only cure is to replace the logic board... which means 750$(Canadian) + Labor + taxes. he said it would probably be around 900-1000$ to fix it. Now, considering this powerbook is worth about that amount of money on ebay, (in working condition), i am very dissapointed as my warranty expired about 2 months ago.
Tough luck mate.

Apple hardware test failed

I have a 3 1/2 year old MacBook Pro 2.6 GHz. Suddenly I started getting kernel freezes....your computer need to shut down.... Sometimes I get the same message at upstart. Sometimes the screen starts blinking and them freezes with grey/green lines down the screen. The Apple hardware test failed with failure code: 4VCD/1/40000003: VideoController. I can start from the restart in hardware test.
Any suggestions out there?? Anything a non apple technician can do?

The service shop said they couldn't do the graphic card test, so they believe it isn't covered by the repair program. But they said the card is the problem, just not that problem

so, I have done re-install from the OSX disk - the first time it failed. I think because I selected the option to keep the user profiles/settings etc, may have been a conflict between vers on OSX CD and vers on HDD? I don't know.
No, it can do that. There are clearly other issues.
anyway an error came back saying the disk was corrupt
The install disc or the HD?
now I thought that sorted it. but after doing the updates. and then going to repair the disk permissions/repair the disk it came back with same error. and also the hardware test is still failing.
The system will never be stable until the HD directory is repaired.
- is the version of the hardware tester I have not compatible with the OS or the firmware i have upgraded to? or does the tester just check the integrity of the hardware regardless of firmware & os vers.
If this is the AHT disc that shipped with your MBP, it is fine, regardless of what OS you have installed.
I really would prefer to not start from scratch again. But could this be an user account problem?
No.
I'll set up a new usr acct and use that for a while. just a pain to bring the files over from my current usr acct to the new one.
I believe that's a waste of your time. As has already been stated, at least one of the issues is the damaged HD directory. Until/unless that is repaired, what you install on the HD isn't going to work correctly, if at all. The big question is, is some other part of the hardware causing the directory damage, or did the directory take a freak "hit" and repairing it will resolve things? It's quite possible that bad RAM or the logic board could have caused the directory damage. You're either going to have to bring it in to an Apple Store "genius" bar and see how much they'll test for free, or do some things yourself. For things you can do yourself, apart from trying one RAM module at a time, and running Repair Disk repeatedly (I don't think that's going to do it), you're going to need to either get your hands on Disk Warrior (or comparable utility), or a different HD, or try the HD in an external enclosure, or get your hands on some different RAM to try.

MacBook Pro failing to boot up despite disk utility repair and PRAM

Problem: MBP frozen on boot up screen with Apple logo and turning gear (which freezes after a while aswell)
Solutions attempted: disk repair via custom recovery- disk utility, PRAM
Device: MacBook Pro 15" (early 2010) running 10.9
Additional info-
Never had any issue with the device and this seems to have happened all of a sudden. Installed an SSD a few months ago, and just realised the ssd did not have a recovery partition. However I connected my older hardrive via USB to access recovery which seemed to work fine.
NOTE: for the past few weeks, every now and then I was unable to power the device off and whenever this occurred, there seemed to be a few bugs (ie unable to empty thrash-error 50 and enable to increase/decrease volume/screen brightness). However, holding the power button and restarting it seemed to have fixed it.
Had the same issue but this time around MBP failed to boot up.
Any possible suggestions?

Ranban wrote:
Are you suggesting reinstalling the os?
No.
Furthermore, is there a way to keep the data intact using this method? Or retrieve it at the least?
Repairing a disk should have no affect on the data, nor would an OSX installation. However if the data has value, there always should be a backup, preferably two.
In your original post you said "attempted: disk repair via custom recovery- disk utility". The term 'custom recovery' to me is alien and thus confusing.
What I am suggesting is a repair of the HDD using the original installation disk, not an OSX installation.
You insert the disk holding down the C key at startup. Proceed with the process until you see on the top of the display a menu bar. Select UTILITIES and from the drop down menu select Disk Utility. Then select Disk Utility>First Aid and then run Verify and repair. Exit from the installation process.
That way I know that the attempted repair was properly executed. You may have in essence done that, but there is an element of doubt in my mind.
Ciao.
