MacBook :: Repairing Disk When All Attempts Have Failed?
Jun 19, 2012
We recently purchased a MacBook Air for a family member. She was using an old MacBook with Snow Leopard. Tried Migration Assistant, but after running overnight, the process hung with "less than a minute remaining." After waiting several hours, we decided to shut down both computers and start over. MacBook Air started up fine, and we were able to migrate from a Time Machine backup. No problems there. The old MacBook was greatly affected. The computer will not start up. The grey screen with the progress bar shows up on boot, but never moves beyond the spinning process circle. I tried booting from the OS install disk to use disk utility to repair it... but the machine seems to not accept the DVD and ejects it.Â
The only mode that I can boot into is single-user mode. I have tried using fsck to repair the disk, but even after many repeated attempts, it exits with "The volume could not be repaired." I think that this is an issue with the B-tree, which must have been damaged during the improper shut down during the migration. Are there any other options for recovering the computer? Again, this will not boot from the install disk, and the only mode that I can seem to access is single-user mode.Â

Is there any way (natively or by an application) for me to know if anyone has tried to gain access to my computer when I've been away and if so to find out what password attempts have been made?

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.

I just got my computer yesterday and when running the "repair disk" function, I already get an error! Since I used migration assistant to move everything off my old mac to my new mac, I'm not interested in reinstalling the whole OS and transffering all my files again. This is a new computer, and shouldn't have this problem this early. I also get the same result when starting up in the recovery partition. How do I resolve this?

Disk Utility when I run verify says I need to reboot from the Repair Disk. I tried (twice) and it shows no problems. When I reboot normally, and run DU, I get the same error. Which result should I believe?? And is there a workaround? Using 10.10.1 / Air late 2011.

I am running snow leopard, have 8 GB RAM and 320GB hard drive
I've had the computer 5 months, and today randomly decided to "repair disk permissions" on disk utility.
Estimated time remaining is 32 mins. So far there is already a huge list of details, mostly things that are supposed to be set at 95 or 1 but are set to 0 (not sure what this means).
Is it supposed to take this long? What exactly is it fixing, and how did these problems arise from simple regular use? Will I notice a difference in my computer's speed afterwords?

I tried to repair my HD but it said that I needed to boot from my install disc and repair then using disk utility. If I boot from the Snow Leopard install disc and then repair my HD, am I going to have to re-install Snow Leopard?

I've been having some real odd things going on with Snow Leopard. I thought that repairing permissions and repairing the disk may help. I ran the tests, but there are errors that look like they cannot be fixed. Below I posted the log file from Disk Utility:
Code:
2009-12-16 15:44:25 -0700: Disk Utility started.
2009-12-16 15:45:12 -0700: Repairing permissions for "Macintosh HD"
2009-12-16 15:46:43 -0700: Permissions differ on "usr/share/derby", should be drwxr-xr-x , they are lrwxr-xr-x .
2009-12-16 15:46:43 -0700: Repaired "usr/share/derby".
2009-12-16 15:47:09 -0700: Warning: SUID file "System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAgent" has been modified and will not be repaired.
2009-12-16 15:48:55 -0700:
2009-12-16 15:48:55 -0700: Permissions repair complete
2009-12-16 15:48:55 -0700:
What I should do since Disk Utility won't repair the problem?

After reading on the internet that you should repair disk permissions around once a month or something I decided to do it after not doing it for ages, so I go and do it, then shut it off and leave it for a bit, and then when I turn it on I open Safari and I notice that its taking a really long time to load Apple's Start Page, so I think nothing of it and turn it off again, then a bit later I turn on and I find the internet on it still just as slow.
So I am wondering if its cause I did it or because of my router.

I bought this G5 with consistant startup problems but after replacing the hard drive,installing a fresh operating system, re-seating the ram, checking the Pram battery, etc, it was running fine. I now realize that when trying to repair the disk permissions, the same list keeps coming back even though it shows it's been repaired. Also, occasionally it may freeze or go into kernal panic on startup. If the hard drive is new, does it sound like a possible hardware problem? Does repairing disk permissions involve anything hardware?

I accidentally changed the disk permissions on my Macintosh HD to "none" for everyone, except system and admin, who both still have read/write/exec privileges. Now, my Mac won't boot up. What can I do to fix this from single user mode or verbose mode?

I've got a problem with my MBP. It finally came back from repair centre today. My Harddrive was broken, so they put a new one inside. Everything worked OK, until I decided to install Snow Leopard, and after that put my superduper backup from my external HD to the MAC hd. I restarted the MAC while I kept holding down the "C" button, (snow leopard disk inside) I went to install OSx menu,-> Disk utility-> MAcintosh HD->last TAB (can't remember the name)-> and dragged the External HD in the first bar, and mac HD in the Second. Also I checked Remove Mac HD when copy the Backup to MAC HD. I pressed the button and the EST time was about 2 hours. After one hour my HD made some noise and gave me an error: Something with Failed to load or Failed to copy. After that it did removed my Macintosh HD drive. It's just Gone! I don't know what to do.. Can't install my mac it's completely useless right now..
Here are some pictures describing the situation:

I'm booted on a MacBook Pro from an external drive, and I want to erase the drive inside the MacBook using Disk Utility from the external. For some reason or another, it won't let me do this. When I click on the Erase tab (whether clicked on the disk itself or the volume "Macintosh HD") and try to erase it, it returns with the error:
Disk Erase failed
Disk Erase failed with the error: Could not unmount disk.
When I try to install an image onto the drive, I get a similar error, except it says "Operation not permitted." When I tried it while booted with an OS X DVD, it worked fine. As far as I know, I should be able to do this while booted from the external HD.

I'm having a pretty serious problem. I attempted to erase the free space on my HD, as I do from time to time, except this time it appeared to hang/freeze at the end, when it gets to the part where it creates a temporary file. I waited for several minutes and it didn't move. I tried clicking the skip button, but that did nothing either, so I force quit Disk Utility.
The problem is, it left the disk at "Zero KB" of free space, effectively making my computer inoperable. I was in the process of studying for a huge exam tomorrow, and am currently flipping out.
If it matters, I'm on a Macbook Pro 2.33 GHz Core 2 Duo, running 10.4.
I really don't want to have to reinstall the OS and import the old files, but my real fear is that I will have to do a fresh install of the OS.

All I get is the quicktime player opened with the correct movie time code and viewing format size but I get no sound and no image, just a white screen.

My hard and back up disk both failed on the same day, strange but the kids were on the computer and things happen.Running Mac OS 10.6 I paid $800 to "super geeks" to recover the pics > 30,000 (many duplicates)I will receive a 500 gig external drive from them today via Fed Ex with the pics recovered . My plan is to move them to my iMac (had a new HD put in) but I do not want to transfer 30,000 pics priorto running duplicate annihilator & thumbnail annihilator on the new external drive. Is there an easy way to do this > looking for help?Can I run the programs on the recovered drive I will receive today prior to my transferring? Or is there a more efficient way of doing this.

I have recently purchased an iMac (21.5" - 3.06 GHz Intel Core 2 Duo - 4 GB 1067 MHz RAM - 1 TB harddrive) with OS X 10.6.2 installed. I have to say that after over 20 years with MicroSoft I am enjoying the stability and quality of the MAC. Anyway, as part of my education in the care and feeding of a MAC I ran the TechTool app yesterday. I had no indication that anything was wrong with the computer - but, I would like to become familiar with the various utilities for the care of the machine "before" a problem occurs. As the app ran I was pleased to see that all the tests passed (Processor, RAM, Video RAM, etc.). However the computer failed the last test: Volume Structure.
Here are the directions I was given at the end of the test: Volume Structure Failed
TechTool Deluxe can scan volumes for problems related to the numerous structures that are necessary for the volumes to operate correctly. If problems are found, TechTool Deluxe can attempt to repair the damage to help reduce the chance of future problems. If TechTool Deluxe has discovered problems with the structure of a volume, allow the program to repair the problem. Quite often these issues are minor, but sometimes they can be indicative of a more serious problem. If the problem persists, consider backing up the device, reformatting the media, replacing the data, and then testing again.
I was also instructed to access the Apple site and download the most recent version of TechTool Deluxe that can perform repairs. I downloaded the software and followed the instructions to open the file in the Disk Utility app and burn a CD. Following the directions I then booted up on the CD by restarting the computer while holding the "C" key. The computer booted up on the CD and loaded TechTool Deluxe. I ran the same tests as above and once again the Volume Structure failed. When I clicked on repair it seemed as though the program was trying to fix the problem - then it abruptly stopped and stated that the Volume Structure could not be repaired.
I removed the TechTool CD, rebooted the computer, installed the TechTool Deluxe that I downloaded from Apple, and ran the Disk Utility. When I tried to "Verify" the disk this is what appeared: Disk Utility stopped verifying "Macintosh HD". 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. Following these instructions I rebooted the computer using the Mac OS X installation disk - and the only option I found was for an installation of the OS.

I purchased a 32gb usb flash drive from ebay. I transferred some music on there, it crashed half way through transferring.
When I restarted and plugged it in, it didn't appear on the desktop. I went into Disk Utility and tried to erase it, I get the following error:
Disk Erase failed with the error:
Input/output error
So I then tried the following in Terminal:
diskutil eraseDisk HFS+ newdisk disk2
But got the following message:

I partitioned my 320GB hard drive into 2 sections, 212GB and 108GB, I removed my 108GB partition with Disk Utility, and tried to only have one partition for my entire hard drive, but the "disk verification" fails! 108GB of my hard drive is inaccessible (it works to make a second partition over the 108GB, but I want a single partition over everything for installing windows with BootCamp) what can I do? would backing up everything and wiping my hard drive and reinstalling everything work?

I have a 2011 Mac Mini. I try to connect to another Mac via Remote Disk. The other computer shows up and the disk appears in the window. However, when I select the disk, I get a message telling me that the operation failed because the original could not be found. Apple Troubleshooting tells me that it has something to do with the firewall. So I turned off the firewall, but I still get the same message. Both computers are running 10.7.3.

I'm trying to format a new external hard drive and it is not working. It is a Seagate 1TB Expansion drive. The box only says PC and Windows, but the guy said 'it should work on a mac too, as long as you format it on a mac', and other people on the internets say it should be fine also e.g. here.
So, when I go into Disk Utilities > Erase tab > change Volume Format to Mac OSX Extended > click erase, it gets about 2% in and then an error window pops up which says "Disk Erase failed. Disk Erase failed with the error: File system formatter failed."
