Power Mac :: Not Booting - Disk Repair Through System CD Fails
Apr 9, 2012
My Power Mac froze, and won't boot. I'm running 10.4. No recent changes, downloads, or updates. Safe mode won't work. freezes on grey start up screen. System CD in drive, won't boot from holding down "c" held down option and selected CD and finally got to disk utility.
Now, when I try to run utility to repair permissions, I get an error stating "disk utility has lost its connection with the disk management tool and cannot continue. Please quit and relaunch disk utility" happens over and over.
When I try to repair disk, I get a red line saying "reserved fields in the catalog record have incorrect date, keys out of order. The volume could not be repaired". Error: The underlying task reported failure on exit (-9972). 1 volume could not be repaired.

My MacBook Pro 2011 stopped booting up. Shows just a white screen. I can get to utilities but disk repair fails, asking me to back up and format / restore the hard drive. How do I back up my data to an external drive?

I ran a disk check on my MacBook Pro which told me to run disk repair. Since this was my boot HD, I took out my Installation DVD, put it into the running system and started the installation file then selected that I wanted to reboot and start utilities. The system then rebooted, the "chime" came, and then, silence, gray screen with apple logo, nothing is happening. What do I need to do, to get further and repair my hard disk?

I have an iMac G5 that I have previously had both the HDD and logic board replaced by Apple. It has been giving me a lot of spinning beach balls lately and yesterday would spin when I did anything as simple as opening Safari. I had tried to repair the disk in Disk Utility, but it failed after a few minutes. Last night I restarted it and it got stuck on my desktop, but wasn't fully loaded. I restarted it with the Leopard disk and I tried both to "Verify" and "Repair" the disk and neither worked. This morning when I tried it again, the only option available was "Verify Disk."
When I do this I get the attached message. It is an iPhone pic, so I apologize for the quality. I'd like to get this figured out ASAP, as we are moving out of state tomorrow! My other thought was I could try to boot with the Leopard disk and do a Time Machine restore. I'm not sure if that would help though. I don't have anything TOO important on the internal HDD, but I would like the chance to pull it out and hook it up to another computer to sift through it. I'm afraid if I do the Time Machine restore something might happen and I won't have the chance to go through the HDD.

Having a major issue: similar symptoms to others in the forum - with the fan and the computer not getting past the grey apple screen, I booted from the install disk and got to disk utility, at first all options were greyed out and I could not do anything, tried again a few times and finally got to the point where I could run the verify utility, never given the option to repair. When running the utility it failed and said I needed to repair by booting from the install disk and running the disk utility? Going around in circle here - any advice? I am currently running the Apple Hardware test to see if that shows anything...it has been a workhorse and I've NEVER had any issues with it.

Using the Apple Disk Utility...
What the difference between running Repair/Verify (Permissions or the Disk itself) on the hard drive or the boot volume listed in the window?
Some say just run it on the boot volume, others say run it on both.
Is there an advantage in doing both (if so, why) or should it be just the boot volume?

I'm trying to recapture/repair my Entourage database on G4 Powerbook running 10.5.8. I've booted from the Leopard installation DVD, but when I try to "repair disk" Disk Utility says the disk cannot be unmounted.Â
Let me backtrack:Â I've run verify permissions and repair permissions.Â
When I run "verify disk" I could a couple of red-letter notaionsÂ
-- Invalid Extent Entry
-- Invalid Extent Entry
-- Incorrced number of file hard linksÂ
and then the conclusion:Â
-- Fileystem verify or repair failed. Â

I have a 2005 G5 PowerMac. It has been locking up lately. Tonight it will not boot. Everytime I turn it on I get to the apple screen and the circle keeps going round and round. I then followed the directions to reset the PMU and I disconnected the second hard drive. Now it will still not boot and gets to the apple screen, circles a couple of times then locks up. I have disconnected everything except the monitor, keyboard and mouse and still have the same problem. The largest issue is the CD drive will not open so I cannot attempt to reload the OS or anything else that requires the CD drive. I do not know if there is a manual way to open the drive. I have searched the help forums and only see the keyboard as an option. I have read many posts that the 9800 video card is a problem - we have an ATI 800 XT and I have not read anything hear about that card being an issue.

Recently I archived and installed leopard from tiger. Since then sometime there is a message that comes up telling me I need to restart my computer in all different languages. Also when I try to verify and repair my disk permissions, this is what shows up:
Permissions differ on "System/Library/CoreServices/Front Row.app/Contents/CodeResources", ....

I have a WD Terabyte drive that I have used for over a year with no problems. A couple of days ago my roommate went to use it and disconnected the drive from my computer without ejecting it first. He used it with his PC and disconnected it without "safely removing" it from his computer and now it will not mount to my desktop of been seen by PC. Disk Utility sees the device but I get an error when I try to repair the disk or verify the disk. It gives me an "error on exit" message. I really need the 700GB of info on that drive. Don't know what to do next.

The Verify failed when checking the drive at the physical disk level, but the main volumes passed.Is this "normal", i.e. should I just be checking the volumes?

I am trying to check my Harddidk by doing a Verify. So I went to Utilities, select the Harddisk, and then click VERIFY.Â
Then I the following message pops out: "Disk Utility stopped verifying "Ryan ManUtd"Â (note: Ryan Utd is the name of my harddisk)Â
Then it the window panel, there is a message which says: "Error: Live file System repair is not supported"Â
What does this mean ? Other than that, I can still access the contents in my harddisk ...Â

Disk Utility says there are a bunch of disk permissions that need repairing. I hit repair and disk utility says that it repaired those disk permissions. But when I verify, it says they still need to be repaired.

G4 won't boot. No startup chime. Power button light goes off right after I power it on. Fans go on and soon switch to high / fast mode.
Tried everything imaginable -- removing all cards, RAM swapping, PMU reset, bought a new 3.6v PMU battery... everything on this forum (I think) except buying a new power supply which I'm trying to avoid.

I had a bad power surge (USB hub that was plugged into the back of the display had the wrong power cord plugged in... very stupid mistake I know!!) take out my 23" Cinema Display. The display shows no sign of life (no power light, etc) and the brick has been tested and is OK. My local service place says that they will have to send the display back to Apple which means a minimum of $400 for repair so I'm wondering if anyone has had a similar issue that they resolved successfully? The service place suggested that Apple would replace the logic board but is there any way to test to see if this is the main issue? I have seen logic boards sold separately online but would be hesitant to buy it without know that this would fix this issue.

Started G5, got a question mark. Rebooted from disk. Tried to repair. Told me it could not exit and complete repair to HD. Restarted again. This time everything in utility window red. Message is Fatal Hardware error to disk utility. Back-up if not completely failed and replace with new drive.
Not great at behind the scenes with my mac. Does this mean a shop visit. Any estimate on cost to me. Had lots of Macs. This is the first to crash and burn and its not that old.

I had a weird issue this morning. I started computer and it did not make the chime sound, it didn't do anything at all. I disconnected it from the extension cord as well as all the peripherals attached to it and nothing. I tried a different start up disk and again there wasn't a sound. Then i unplugged it and reset the SMU on the mother board and air sprayed the computer to remove all dust. Then plugged it back and it came back on.

I am considering purchasing diskwarrior but want to make sure it can help my situation before I purchase it. My imac will not boot from the internal hard drive (Intel processor) When I use disk utility to try and repair the disk, I get error messages and it won't repair. I can see the HD but cannot repair it. When I connect using target mode with my mac book pro, the hard drive does not appear on my host (macbook pro) computer. I have reloaded OS X (Leopard) onto a firewire external drive and can boot my imac that way but I can not find my original internal Macintosh HD. Will disk warrior be able to help with this scenario. I would really like to access that internal Macintosh HD and retrieve my files.

I have a 2TB Western Digital My Book Studio FW800 external that has 5 partitions, connected to my 2011 iMac. I had help doing the partitions and don't really remember the reasoning, but one is just for my SuperDuper! backup, one is Miscellaneous, one for movie clips off my camcorder, one for misc scanned photo's and one for my genealogy research. I back up using Time Machine to a Time Capsule and also to this WD hard drive with SuperDuper!Â
Recently I'm getting a pop up message that "Mac OS X can't repair the disk "Genealogy"'. And it needs to be reformatted. It's become a read only disk. When I look in Disk Utility it shows all the partitions as "Mac OS Extended (Journaled)" EXCEPT for the one in question. I also noticed that there are a lot of files with "date created" being the same date in 1969! These files may be letters I've written or photo's I added to that partition within the last few years.Â
I think I have to completely reformat the entire external hard drive to repair this, but I want to make sure. Because it's going to be a major hassle backing it all up to another external (having to get one first) and then figuring out how to make the files that have turned "read only" in that one partition, back to their original state!  Does this sound right, that I have to reformat the entire external hard drive? And how do I get the read-only files back to their original state.

I'm trying to repair my hard drive. I restarted from the OS X Mac Mini install CD (holding down the letter C when I heard the chime), opened Disk Utility from the Utilities folder, selected my hard drive image, but the "verify disk" and "repair disk" options are grayed out. I'm at a loss as to how to proceed.

One of my drives is showing issues that Disk Utility isn't catching or can't find. I've heard about Diskwarrior, iDefrag, Drive Genius, etc... but which one is the most comprehensive, is there a "best of breed" disk app out there or one that does more than the others?

Macbook Pro running on OSX Mavericks is having problems.Â
Today I turned my Mac on, and it started up with a loading wheel and a loading bar. When the loading bar finished, the Mac turned itself off. I tried many times, same happened every time. I then went into OSX Recovery, started repairing Macintosh HD, but the error message saying "Disk Utility can't repair Macintosh HD" came up and now I don't now what to do.Â
Is there any way I can back up my files in this situation? Is there any way I can repair the disk without having to erase all data and reinstalling OSX? Or do I really need to bring it to a Apple Store for repair?Â

MacBook Pro, OS X Mavericks (10.9.4)
