MacBook Pro :: Repair Corrupted Hard Disk When Don't Have A Startup Disc Provided By Apple?
Feb 24, 2012
So my MBP was really making horrible clicking noise and I figured out that my start up Lion OSX disk partition is corrupted. I have three partitions. One for Lion OS X, another for Documents and another for Movies and Downloads. When I run disk utility and verify other two partitions(documents and movies/downloads), they appear to be okay but when I do the same with Lion OS X then it says:
The volume Lion OS X was found corrupt and needs to be repaired.Error: This disk needs to be repaired....then use Disk Utility to repair this disk. Is my hard drive gonna die soon? Or will it be okay if I just format my 500gb hard drive completely and install the fresh copy of Lion OS X again? I don't have a recovery disc or what so ever provided by Apple anymore. I have a DMG installation file of Lion OS X and a USB flash drive(4 GB approx). How can I repair the disk partition without the recovery start up disc?

There's a flashing folder at startup and won't boot. I've tried the disk utility on the install cd but it cannot be repaired. It repaired it once, but when restarted it happened again. Ive also tried to reset the pram (not ire if thats what its called) and tried recovery hd, but those didnt work either. I want to backup my files, mainly pictures, but don't know how or if it's even possible through disc utility.

My Macbook is starting to get really slow. I've tried Onyx and it told me that the startup volume had to be fixed. But I can't boot my install DVD by pressing "C" in the startup.
Is there another way to repair the disk?

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.

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.

My service battery warning has come on, and that obviously means a new batter, but i don't want/can't pay for a new battery. Would that be covered under my apple care?

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.

Over the last few weeks, I have been experiencing crashes on my Macbook Pro. The crash would appear as such: I'll be using Chrome and all of a sudden pages won't load. The mouse continues to work, but if I navigate to the desktop, folder won't open. Then, if I try to quit programs, the dock either becomes unresponsive or programs will only quit if "forced quit." Then the beachball of death appears. The beachball of death will continue for a very long time—perhasp indefinitely, so I decide to manually power down the computer.
I have tried to verify the hard drive in Disk Utility, and a few times I have gotten this error: Volume bitmap needs minor repair for orphaned blocksChecking volume information.Invalid volume free block count(It should be 46122698 instead of 42839276)The volume Macintosh HD was found corrupt and needs to be repaired.Error: This disk needs to be repaired using the Recovery HD. Restart your computer, holding down the Command key and the R key until you see the Apple logo. When the Mac OS X Utilities window appears, choose Disk Utility. So I restart from the system (command-R) and repair the disk. But now within a day or two I get the same error. Does my hard drive need to be replaced? Am I on borrowed time? My computer is under warranty. Do you think Apple will replace the hard drive?

My MacBook is unable to boot. Whenever I try to boot, the spinning circle and the progress bar appears on the grey screen, but when the progress bar reaches about 40%, the computer shuts itself down. I started in Verbose Mode and tried AppleJack, and it said my harddisk needs to be repaired; but AppleJack is unable to do that. (Error Messages: "Invalid node structure" and "Incorrect number of thread records) I then tried to startup with both Recovery HD and Mac OS X Install DVD and ran the Disk Utility on both of the startups. At the First Aid tab, I selected my Hard Drive (not the Hitachi one, the Macintosh HD one) and clicked on Repair Disk. The error messages I got from Repair Disk were:Invalid volume file countInvalid node structureThe volume Macintosh HD could not be verified completely.
Error: Disk Utility can't repair this disk..disk, and restore your backed-up files. And, lastly, the following popup message appeared:Disk Utility stopped repairing "Macintosh HD"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. Not being sure how to back-up my files using Disk Utility, I plugged in an external HDD to my USB port and clicked on the Restore tab in the Disk Utility. As the Source, I selected Macintosh HD and as the Destination, I selected one of the partitions I created on my external HDD. However, when I clicked on Restore, I got the following error message:Restore FailureCould not restore - Input/output error I partitioned my external HDD by creating 2 partitions formatted in Mac OS Extended Journal - GPT. Now, what can I do to save my files (and my MacBook's HardDisk)?

I edited a wedding on Final Cut studio. Both the software as well as all my uploaded footage collected on an external harddrive. BOOM My hard drive completely becomes corrupt and I can't mount it (meaning my computer doesn't recognize the drive). I then purchased a data-recovery software and, after about two hours, recovered the corrupted files. I then downloaded "VLC" as well as "DIGITAL REBELLION" to repair the files and they cannot seem to do so. Case and point I need these MOV. files as soon as possible and I turn to this forum for guidance of any kind. My Mac is a desktop iMac. It's completely updated and I'm running on iOS X 7.3.

So so annoyed right now. Today my 12" G4 powerbook started to become slow, lots of spinning wheel, delayed menus etc. I checked file permissions, rebooted and it just kept on getting slower. Eventually it wouldn't get past the white apple screen.
I booted off the Tiger DVD and ran disk utility to fix and repair permissions again. It wouldn't let me repair the disk as I kept getting this error:
'Repair volume failed with error could not unmount disk'
I had to reboot again, and eventually my hard disk no longer appears in Disk Utility. I tried to boot into safe mode and get this:
'"I0ATAController device blocking bus
I0ATAController device blocking bus
I0ATAController device blocking bus
I0ATAController device blocking bus
I0ATAController device blocking bus"
So now I pretty much can't do anything with it. Failed Hard Drive?

I have had a problem for about a month whereby my MBP won't shut down, it just hangs after it has cleared the desktop and only the wallpaper is displayed. Now disk utility won't see the disk at all, and Software Update also does not find any updates. It checks for new software for ever. My mac starts up fine, and I can use it as normal.

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?

I installed ntfs3g on my MBP and it seemed to be working correctly and I had write access to my usb disk.
While I was copying a large file to my disk, the disk was suddenly unmounted from OSX ( I had a warning saying that I should use proper unmount the next time).
I mounted it again but now I cant access the directory I was trying to copy the large file anymore. All the content of this directory is not there anymore.
When I try to access it via Windows, it says "Directory E:Backup is not accessible. The file or directory is corrupted and unreadable"
... owned
What shall I do ? It seems that the other directories are ok. I'd like to recover the lost directory but I'm scared to screw up and lose everything.

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!
