MacBook :: Repair A Disk Using Another Computer
Apr 18, 2012
My son has a MacBook, but the optical drive is broken. The HD needs repairing from the disc. How do I repair his disc using the Installation CD on my MacBookPro.?
I have tried restarting his computer while pressing: command C, also optionC, furthermore option-command-C and alternatively using D instead of C, but it restarts in the administrators password window....
And on mine, I have opened migration assistant and put in the disc so its readable to my computer...
It seems I have 2 problems. The rebooting on the C-D letters don't seem to work, and is it with the migration assistant that I can hel repair the disc?

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.

Macbook Pro running on OSX Mavericks is having problems.
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.
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?
Info:
MacBook Pro, OS X Mavericks (10.9.4)

I have a Seagate 1 TB Backup Plus Drive which was working perfectly fine until I plugged it into a USB hub. It detected it while in the hub and I was able to get files off of it, but when I ejected it from the hub and put it back into the USB slot on the computer it was not detected by finder. It shows up in the disk utility and I clicked verify and repair and it says:
Verify and Repair volume “Seagate Backup Plus Drive”
Checking file system
Volume repair complete.
Updating boot support partitions for the volume as required.
Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
Is there any way to get this to work properly again? Or if not is there a way for me to recover my files on the external hard drive?
I have a Macbook PRO late 2011 running OS X Mavericks.

Fortunately I got a time machine backup. And its restoring the drive while in Lion recovery mode. Here's what happened... I dont have a router a my place at the moment and so my two phones (iphone 4 and htc android) connect to my internet using my MBP's wifi via internet sharig. For some reason they were not able to get an IP from the mbp. After doing some wifi swtich toggles and forgettig & rejoining the network, i decided to reboot all my devices. I shut down my modem, phones and restarted my mbp. On reboot, after the chime, it showed an unsusal 'progress bar' under the apple logo. The bar progressed to about 10% and then the mbp just powered off. This happened several times even after PRAM and SMC reset.
So now i booted with cmd+r pressed and in recovery mode ran a 'verify disk'. It said the verification stopped and that i should repair the disk. When i tried to do that it said the disk cannot be repaird and that i should back up as many files as possible and attempt to format the disk and restore it with time machine. It is precisely what im doing at the moment.
1. Mbp wont sleep even when internet sharing is off
2. Mbp wont lit the onboard display upon opening it in clamshell mode until i removed the 3.5mm audio cable of my speakers from the audio out port!

I just saw that the amount of memory left on my HD just dropped around 60GB, so I used the "Verify Disk" option on Disk Utility, and the output was: Verifying volume “Macintosh HD”Performing live verification.Checking Journaled HFS Plus volume.Checking extents overflow file.Checking catalog file.Checking multi-linked files.Checking catalog hierarchy.Checking extended attributes file.Checking volume bitmap.Checking volume information.Volume header needs minor repairThe volume Macintosh HD was found corrupt and needs to be repaired.Error: 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 don't have the disk right now, so is there some other way I can repair it, get another install disk, or anything else? I've been thinking of booting up with a Linux livecd, but can it access the HFS+ filesystem?

My Macbook crashed so I tried everything to restart it. what finally worked is opening it from the install disk. I performed a "repair disk", and after saying "invalid node structure" and "invalid record count", it says it cannot repair the disk. I don't know what step to take next. How do I see if time machine has backed my files up? Do I need to erase the HD and reinstall?

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!
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.
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?

Running Disk Utility's Repair Disk function from DVD, how long should this take to complete with a 1 TB drive? It's been nearly 24 hours so far. I booted the computer from the DVD, and after verifying the disk was told the disk needed repair.

I have run the Disk Utility verify function against my system partition. It tells me there are minor issues that need fixing up and I should run the repair disk function, by booting using Command-R and using the Disk Utility to repair the drive.Problem is, when I boot using Command-R and select Disk Utility the partition is shown greyed out and the Verify and Repair options do not work.I think this could be because the partition is encrypted. The utility does not offer me the chance to unlock the partition with my passphrase.How can I repair the filesystem errors on this partition?

I have a very old E Mac running version OS X version 10.1.5. My Mac is showing a flashing question mark so I have tried to repair it using the Install Disk provided with my E Mac. Unfortunately, when I insert my Mac OS X Install disk (which is for version 10.1.4) and press the C key at startup and click on Disk Utility the "Repair Disk" button is greyed out (although I am able to Verify the Disk.) How do I get round this problem? (I should add that I have had the flashing question mark once before, and I was able to repair my E Mac on that occasion as I was able at that time to click on the "Repair Disk" button. However, I can no longer do this.)
I have also tried using my OS 9 Install Disk, as I was using OS 9 the last time before the flashing question mark appeared. When I go into Disk Utility using that disk, I am able to click on the "Repair Disk" button but it lists errors that it says it is unable to repair.

Yesterday I decided to Install Windows Xp on my Mac. I tried to partition it but BootCamp said, "Verifying failed. BootCamp can't partition disk." So I started reading about this problem on the Internet and I found out that I have to use the Mac OS X Installation Disk and use the Disk Utility to "Repair" the disk. I started Disk Utility and clicked "Repair". Many files were missing so it tried to repair it. So now when I start the Apple-logo and the loading-circle is "frozen", so it just loads and loads and loads and loads, and nothing happens. I decided to format the disk from Disk Utility but I can't format it! I can't do nothing! So now I cant start my Mac! If it is possible to take a backup or something before I format it, or keep the files it would be lovely!

I just tried to verify my HDD, and Disk Utility said: Invalid node structure. Volume check failed. Error: Filesystem verify or repair failed. Now when I tried to reboot my Macbook, the gray Apple comes up and so does the spinning wheel, but after a couple of minutes, it shuts down.

Right, my macbook won't boot so i brought a copy of the SL disk from Apple. Put cd in went through to the click continue screen and clicked the Utilities and then Disk Utility and chose my drive and clicked 'Veriy Disk' Clicked that and it said it needed to be repaired and click the 'Repair Disk' button. Done that and it gets through some of it then spits up and error message saying the disk cannot be repaired.
I really need my stuff off of there becuase have'nt got a back-up so if someone could at least tell me how to recover my things i would be really greatful.

I've done repairs 3 times but after a few days I'll run Disk Utility again and it says the same thing again.
Is this a sign of a fault, future issues or is it just something she's doing?

Lately, my MacBook Pro (mid 2010) started to slow down even with over 60% disk space is empty and max RAM is installed. It gets slow when using hungry programs such as Photoshop CS5.
I used the disk utility first aid and fixed all permissions that were shown with errors. When scanning the disk, I received the message that my disk is corrupt and I need to fix by restarting with command+R keys pressed until the apple symbol is displayed. When the next window shows up, choose disk utility and go from there to fix the disk.
When I performed that, I let go of the Command+R keys after the apple logo came up, the only thing that came up after that was a grey circle with a diagonal line through it and a spinning clock.
