Efiboot mba can't boot can't repair

I have a 9 week old MBA.
Im quite impressed with Lion (its my first MAC) and the ease of dualbooting.
I have Windows 7 dualbooted with Lion using MacDrive to see Macs files.
Ever since two days ago, I can no longer boot into "Macintosh HD".
It just started showing "EFI Boot" instead of Macintosh HD under the boot options.
The file system seems to be in tact.
I tried using DiskUtility to verify and then repair the volume.
The Macintosh HD comes up as unmountable. Verify  told me to repair.
Repair told me it could not repair and that i should  copy my files and reformat.
I can still boot into Windows 7 and can still mount the Mac filesystem from within MacDrive and see all my Mac files (properties shows as HFSJ filesystem).
So i used that to copy my entire user directory onto an external hard drive if i need to reformat.
I then tried erasing the drive in DIskUtiity but it coudnt see it as it was unmountable there.
I also tried fsck under single-user mode (which i can still access and access all files from).
It reported repeatedly of an "Incorrect number of thread records (4, 26002)."
Also i have a "DamagedFiles" directory with four files in it:
Two asl files like this one (001dcf0e 2011.09.23.G80.asl)
An plist file named ############ julius.plist where julius is my username. This file seems to just point to julius.plist
And another number eg. ################# file.
What happens when i boot into EFI Boot, is it takes an age to load - but then it successfully loads the Mac login screen but my user login doesnt show, and i try to login with my credentials but it wont recognise them.
Also, i cant reinstall the operating system like i have done before over my wireless as at some points it asks me for AirPort login credentials which it doesnt recognise when i put them in.  It doesnt seem to recognise me anymore.
Also under single user mode i tried typing a fix i found on the net:
sudo bless -- folder/system/Library/CoreServices --bootefi
and it just says "No Volume Specified."
I do not know why it has done this.
I did recently do a MacDrive update (i think), and also, have once or twice needed to force a shutdown for different reasons.
Any help is much appreciated.
I was really liking Lion and GarageBand and XCode and now i have a 9 week old MBA that only boots into Windows 7.

After reading this post
At least on the login side my problem seems like it might be similar. However probably worse, with the incorrect threads and not mounting.
But i cant login with another account, and my account was the only login and was root user.
Anyone know how i can fix my problems? Or else, how would i go about erasing this boot volume entirely and reinstalling it considering i dont seem to have access to the wireless nor do i have a usb/dvd with the operating system on it...
I also obtained a copy of Disk Warrior as i read of cases where it helped similar issues but i dont know how to run the dmg from the single-user prompt.
Also i tried from single-user some queries that the post linked at the top of this page suggested :
$ id julius
> "no such user"
$ dscl.read/uses/julius
> "no such file or directory"
$ sudo ls /var/db/dslocal/nodes/Default/users
> lists the users including julius.plist
$ sudo defaults read /var/db/dslocal/nodes/Default/users/julius
> "domain does not exist"

  • HD corrupt, disk utility can't repair it. can't boot.

    I have a early 2009 iMac with the latest Mountain Lion update (did the last update two days ago). My HD has two partitions: one for os x and one for windows with bootcamp. I'm curently writing using the windows partition where everything works fine.
    Yesterday I started my mac on X. Same gray loading screen but it had a small bar on the bottom. When the bar reached nearly half, the mac shut down. This happens now every time I try to start the mac on X and if I keep pressed ALT to choose which partition to use, the one for X is called "EFI Boot".
    I booted in recovery and later using a snow leopard dvd, and I used disk utility. It said "invalid index key" and that the volume needed to be repaired, but disk utility couldn't repair it.
    I tried rEFIt to check if there were problems with the partitions: all ok.
    I tried the fsck console command: all ok.
    Now I'm in the windows partiton and if I navigate through the X partition (I have MacDrive installed) I see that some files are missing. I'm sure they should be there, but they're nowhere to be found.
    Of course MacDrive tells me that the volume is damaged, etc...
    What can I do?

    What files are missing?
    Might try this...
    Just recently I ran into a problem when I tried to Verify my hard disk and when it tried to verify the catalog, it responded "Invalid sibling link." Repair Disk didn't work. I searched the web and Apple's site, and couldn't find anything useful except to buy DiskWarrior or reformat the drive. Knowing that OS X is built on Unix gave me a few clues on how to proceed. The solution is pretty simple:
        1.    Boot off the OS X CD (reboot, hold C while booting).
        2.    The installer will load up, go to Utilities in the menu and run Terminal.
        3.    Type df and look for the drive that has your Mac system mounted---you'll have to unmount this. On my MacBook Pro, it was /dev/disk0s2.
        4.    Type umount /dev/disk0s2, replacing disk0s2 with whatever disk your OS lives on.
        5.    Type fsck_hfs -r /dev/disk0s2. If you umounted the wrong thing, it will complain that you can't repair a mounted drive. Go back and umount the right thing and repeat this step.
    Just for fun, you might want to run another fsck_hfs on your disk (use the -f option because your drive is probably journaled). Hope this helps someone so they don't buy a program that's going to do pretty much what we did with fsck_hfs, and so they don't waste time searching for an answer to no avail. By the way, TechTool Deluxe (3.1.1) didn't find the Catalog problem for some reason (you'll have this on a CD if you have AppleCare), which is why I resorted to fsck.

  • Macbook Pro not booting after update. ''Disk Utility can't repair disk''. Help needed!

    I have recently updated my macbook pro as I had some pending software updates. I left it to do the job over night and the next day I noticed it was not letting me sign in to my account session as usual.
    I restarted the computer and ever since then when I boot it, it just shows the apple grey screen with a bar that loads to about a 3rd and then it turns off again. I have contacted apple but they were unable to help me with this.
    So far I have tried to:
    1. Re-install OS X 10.8 - but it says the disk is locked or OS X cannot be installed on Recovery HD.
    2. Verify and Repair the disk and I errors but it cannot fix them. Some are:
                   'invalid leaf count''
                   ''missing thread record''
                   ''incorrect number of file hard links''
                   ''overlapped extent allocation''
              and it finally says ''the volume Macintosh HD cannot be repaired'' Error: ''Disk Utility can't repair this disk.. disk, and restore your backed up files.
    I would like to know a way to back up my files so that i can completely restore the disk without any data loss as I havent backed up for a while!
    If anyone has any solution to this issue it would be much appreciated!

    I just ran the Disk Utility, and cannot very disk. It gives me an error message;
    Error: The underlying task reported failure on exit
    1 HFS volume checked
    Volume needs repair
    and when I run the repair, this is the message:
    The volume GERRARD could not be repaired.
    Error: The underlying task reported failure on exit
    1 HFS volume checked
    1 volume could not be repaired because of an error
    Repair attempted on 1 volume
    1 volume could not be repaired
    Prior to running Disk Utility, I have already tried DiskWarrior, and could not repair my disk. Anyway I can fix this problem??? Formatting the disk would be my last option (though I am unsure if it will fix the problem). Any advise would be greatly appreciated. Meanwhile, I will continue to back up my file, and delete unused data and try to run it again.
    Thank you all very much for any input.
    Cheers,
    Matt

    Hello USME,
    'Tis a common problem on old Macs.
    Do as Allan says: open the door and blow out all the dust bunnies. Canned air from Wal-Mart or Radio Shack can be handy (though sort of expensive) especially for blowing through the back of the power supply. A cool Mac is a happy Mac.
    Be sure your Mac can breathe. The air intake is on the bottom of the case, so be sure a deep pile rug or too many papers on your desk are not blocking the air supply.
    Feel the power supply and the processor with your hand. They should be warm but not hot; if you have to move your hand away, that's too hot!
    Check the fan on the power supply, and on the processor if it has one. Take a flashlight and peer in the back of the (Mac) case through  the grille; make sure the fan is turning. If it's not, the power supply won't work for long.
    Fans are not considered serviceable, though they will succumb to mechanics of determination. A CPU fan is easy and straightforward.
    A fan replacement will not cure an already damaged power supply; the PS may already be done for. Used power supplies for a DA are hard to come by, and not especially cheap when found (c.$50). An entire  working DA or Quicksilver may often be found for under $100 on eBay, and swapping in your HD is easy and simple... this might be cheaper and more expeditious than repairing an expired DA. Replacing a power supply is fairly easy, but it's a nuisance and requires a 2mm Allen head wrench in addition to the usual #2 Phillips head screwdriver.
    In my experience, power supplies and CPUs are about equally likely to fail. There are a few other possibilities, but they are not nearly so common.
    Good luck!... Jon

  • Macbook pro won't boot and when I tried to back up the hard drive I got "disk utility can't repair this disk backup as many of your files as possible"

    My macbook pro froze and initially would not even recognize the power chord. Now it charges, but will not load up. I opened in in disk utility to try and back it up so that I could take it to apple to have it fixed but I got the message that said "disk utility can't repair this disk backup as many of your files as possible". How do I back up the files???

    Nichelle215,
    you can try the method described on this Apple page, in the “Instructions for backing up to an external hard disk via Disk Utility” section. (You can skip step 6, since you already know that your disk is irreparable.) Note, however, that this method is not guaranteed to work. Once you get your disk straightened out, you might consider purchasing an external hard disk for use as a Time Machine backup destination, so that a similar problem in the future won’t wipe out the only copy of your files.

  • After getting the dreaded gray/blue screen, I tried to run disk repair on the internal disk. I got an error message saying "Disk Utility can't repair this disk and restore your backed-up files. The volume Macintosh HD could not be verified completely

    After getting the dreaded gray/blue screen, I tried to run disk repair on the internal disk. I got an error message saying "Disk Utility can't repair this disk and restore your backed-up files. The volume Macintosh HD could not be verified completely." What do I do now? This is an iMac and I'm running 10.6.8.

    Clean Install of Snow Leopard
    Be sure to make a backup first because the following procedure will erase
    the drive and everything on it. See below for how to clone a drive.
         1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
             with your computer.  Insert the disc into the optical drive and restart the computer.
             After the chime press and hold down the  "C" key.  Release the key when you see
             a small spinning gear appear below the dark gray Apple logo.
         2. After the installer loads select your language and click on the Continue
             button. When the menu bar appears select Disk Utility from the Utilities menu.
             After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
             size.)  Click on the Partition tab in the DU main window.  Set the number of
             partitions to one (1) from the Partitions drop down menu, click on Options button
             and select GUID, click on OK, then set the format type to MacOS Extended
             (Journaled, if supported), then click on the Apply button.
         3. When the formatting has completed quit DU and return to the installer.  Proceed
             with the OS X installation and follow the directions included with the installer.
         4. When the installation has completed your computer will Restart into the Setup
             Assistant. Be sure you configure your initial admin account with the exact same
             username and password that you used on your old drive. After you finish Setup
             Assistant will complete the installation after which you will be running a fresh
             install of OS X.  You can now begin the update process by opening Software
             Update and installing all recommended updates to bring your installation current.
    Download and install Mac OS X 10.6.8 Update Combo v1.1.
    You may be able to backup your data if you have an erased external drive you can use. Before you do the above but after you have opened Disk Utility you can try to clone your drive:
    Clone using Restore Option of Disk Utility
      1. Open Disk Utility.
      2. Select the destination volume from the left side list.
      3. Click on the Restore tab in the DU main window.
      4. Select the destination volume from the left side list and drag
           it to the Destination entry field.
      5. Select the source volume from the left side list and drag it to
          the Source entry field.
      6. Double-check you got it right, then click on the Restore button.
    Destination means the external backup drive. Source means the internal startup drive.
    Now this will only work if the drive is accessible and can be cloned by Disk Utility. Otherwise, you would need to access your drive from another Mac that you can connect via Firewire - Target Disk Mode.

  • Can I fix a disk with this message?-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.

    Can I fix a disk with this message?
    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.

    Some problems can indeed be fixed this way. But working from Recovery_HD or Disk Warrior DVDs and working in the restricted environment those provide can be difficult. You can literally spend days working on this problem (while your regular work is unavailable) only to discover the old drive is unsalvageable.
    There is no way to know up front whether you are facing a major Hardware failure or a minor software glitch, or something in between. Often you are forced to work from the drive you no longer trust. I continue to recommend you do this work from a different, fully functioning Mac OS X booted from a different drive.
    If you have had the foresight to (as The hatter often recommends) clone your virgin install onto another drive for use in such situations, you will be able to recover from such problems in record time. If not, my previous recommendations stands:
    Buy a new Drive. Or  two. Install Mac OS X from scratch on a new drive, and get your Mac running again. Later, you can use the full power of Mac OS X to attempt to rescue your data, if needed. Then Zero the old drive, to see if it can hold data again reliably.
    If the old drive eventually provides some needed data, and is salvageable, Merry Christmas.

  • External Hard Drive Disk Utility Can't Repair the Disk

    Hi,
    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?
    Thanks
    I have a Macbook PRO late 2011 running OS X Mavericks.

    Use a more powerful utility such as DiskWarrior, or a product such as those listed here.

  • Disk Utility can't repair TM backup disk

    Hello all
    Recently, my external backup disk (a 750 GB WD My Passport) that I use with Time Machine has been acting up. At first, it wouldn't show up on the desktop, but was being recognized in Disk Utility (with the "Time Machine Backup" partition greyed out). After multiple restarts and unplugging/replugging the hard drive, I finally got to be properly recognized, i.e. it showed up on the desktop with the proper Time Machine hard drive icon. So I thought the problem was gone and started a routine backup. However, Time Machine returned an error:
    "Unable to complete backup. An error occurred while creating the backup folder."
    I search the forums, and followed the advice here: http://web.me.com/pondini/Time_Machine/C10.html
    I tried repairing the disk, but DU couldn't repair it:
    Verify and Repair volume “Time Machine Backups”
    Checking Journaled HFS Plus volume.
    Detected a case-sensitive volume.
    Checking extents overflow file.
    Checking catalog file.
    Incorrect number of thread records
    Checking multi-linked files.
    Checking catalog hierarchy.
    Checking extended attributes file.
    Checking multi-linked directories.
    Checking volume bitmap.
    Checking volume information.

    (It should be 3991498 instead of 3904049)
    Invalid volume directory count
    (It should be 678218 instead of 673790)
    Invalid volume free block count
    (It should be 9588404 instead of 11784378)
    Volume header needs minor repair
    The volume Time Machine Backups was found corrupt and needs to be repaired.
    Volume repair complete.Updating boot support partitions for the volume as required.
    Error: 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.
    So now I'm still following the advice on the above mentioned page by posting on here. Any help at all would be greatly appreciated. I am using a 2010 15in 2.66 i7 MBP, if that makes a difference, although my guess is the problem's with the harddrive itself. I think there may have been one time about a month ago when Time Machine stopped responding (or something like that) which forced me to pull out the harddrive, possibly corrupting the data. But I'm not sure, and I do recall making at least one successful backup after that. Well, actually TM confirms this: "Latest successful backup: 5/27/11 at 11:51 PM". So I have no idea what's going on. Again, any help would be appreciated.

    You can't tell what's corrupted or where.  Time Machine backups have a very complex structure, all linked together.  So, you can often do new backups, or restore individual items, or even entire backups, as long as you don't stumble over the damage.
    There's a chance a heavy-duty 3rd-party disk repair app, such as Disk Warrior, can repair them.  It's about $100, and probably a good investment for the future, but there's no guarantee it can fix them.
    If not, or if you don't want to spend the money, your only option is to erase the disk and let Time Machine start fresh.
    It sounds like you may have other data on it; if that's in the same partition, that's not a good idea.  This is a good time to copy the data off, erase the disk, and make 2 (or more) partitions on it, so Time Machine has its own, exclusive space.  See #3 in Time Machine - Frequently Asked Questions for details and instructions.

  • Disk Utility can't repair this disk

    I have been having trouble booting. It started when I connected a router to it. It seemed to eat up the free disk space and I only have 77 MB left or something around that.
    Anyway, I tried deleting files with command-s commands, and it worked one time and it freed up 2 GB of space. I restarted the computer and when I tried to start it up, it still got stuck in the gray screen with the whirly thing at the bottom. I checked the space and it was 77MB now.
    I decided to boot from the Install Disk (Snow Leopard 10.6.0).
    I checked Disk Utility first and verified the disk. It came up with the message:
    "Error: Disk Utility can't repair this disk .... disk, and restore your backed-up files."
    What should I do now?
    I have the Mac HD volume on backup already so I don't have to do the back up stage.
    Should I erase the disk while I am in Disk Utility?
    And format it to Mac OS Extended Journal?
    And then install the operating system again?
    Thanks.

    To answer your questions, first, some other options...
    If you fill your disk up that far, you are going to have problems. Don't ever do this, 10% is a bare minimum, you may need even more, depending on the size of your disc.
    I have seen before where a disc repair utility couldn't perform its function simply because there was not enough slack space available on the drive. While I have never seen this with disc utility, it is possible that the disc is repairable as-is, if you could just free up a couple more gigs of space first.
    Secondly, you could also try Disk Warrior, or to a lesser extent, Techtool Pro, or even iDefrag. I have personally never had Techtool Pro fix anything that Disk Utility or Disk Warrior couldn't fix, so I hesitate to even mention it, but I have had Disk Warrior and iDefrag clear up problems that Disk Utility either couldn't detect, or couldn't fix.
    If you are still in dire straits, you should re-partition the drive using disk utility. This is the safest route, then go from there.
    good luck!

  • Disk Utility can't repair Macintosh HD.  What should I do?

    Here is a "quick" synopsis of what has happened thus far:
    About one month ago, my computer started getting very sluggish (ie, it would take forever to startup, would always freeze after sleep, etc.)  I lived with it for about two weeks, since it would always run quickly after waiting ~30 minutes after starting/waking up.  Eventually, this grew old.  I browsed the internet and did multiple suggested fixes (reset PRAM, run Disk Utility, ran in Safe Boot Mode, etc.).  Nothing seemed to work.  I opted to zero out the harddrive and reinstall Mountain Lion after making a backup.  That was about two weeks ago.
    Everything worked fine, up until yesterday.  Once again, things started getting slow.  I decided to shut down my computer for the night and would check it in the morning.  When I turned it on this morning, it wouldn't startup correctly.  I could login, etc., but it was frozen and I couldn't open any applications without getting the spinning beach ball.  I waited about an hour, but it was still slow/loading.  I shut the computer down and booted it in Verbose Mode.  I ran the various commands to check the conditions of my disk, but when I ran the "fsck -fy" command, I got an "I/O Error."  I then tried rebooting my Mac, but it would get to the gray screen with the apple logo and the spinning wheel, and then the progress bar would appear.  Before the progress bar did anything, it would shut itself down.
    I then started the computer up and directly went to OS X Utilities.  I went into Disk Utility and tried to check permissions and repair the disk.  Only this time, Macintosh HD was grayed out and seemed to be unmounted.  I couldn't get it to mount.  I went into the Apple Store to have them run their own diagnostics.  However, the apple store employee was unable to get the test working, so that was basically a bust.  At this point, the computer still didn't turn on.
    I got home and, just for kicks, held the "N" key while booting up my computer.  For whatever reason, my computer started up (though it took a long time and there was a progress bar).  Now, I made another backup of my disk and am wondering what to do.  I ran Disk Utility again to repair my disk, but it says that Macintosh HD is not able to be repaired.  When I checked permissions, there were tons of Input/Output Errors.  Based on my research, it would appear that I have two solutions.
    I can either purchase DiskWarrior and use that to try and solve my problem, or I could just get a new hard drive (and I would upgrade to a SSD or SSHD).  DW is about $50 if I just download it, and the hard drive would cost me $150 or so.  Since I don't know exactly what is wrong with the disk, I don't know if DW would be able to fix it.  That being said, if the hard drive isn't the problem, there would be no reason for me to purchase a new one.  I guess I would just like some advice, as to what you would do.  I apologize for the long post.
    TL;DR: Disk Utility can't repair Macintosh HD.  Should I get DiskWarrior or a new harddrive?
    Thanks in advanced!

    Most importantly, youve already backed up all the data.  All else is cake.
    A new HD would cost you only $20 more than disk warrior,....theres no reason to repair a worthless crippled HD, .....new HD 1TB is $70.
    Once you back up all the data on a failing HD, further diagnosis has no meaning,....not anymore.
    Grab a 1TB  or 750GB  Toshiba/Hitachi (both used by Apple inside their Macbook Pro nonRetina,...both are made by Hitachi)  5400RPM SATA HD.
    Forget the repair,.......repair only serves to bring a HD to a point of BACKUP.....since youve already done that, its now just wall art or trashbin fodder.
    These are the same HD used by Apple in their Macbooks
    http://www.amazon.com/MQ01ABD-2-5-Internal-Hard-Drive/dp/B0077CV2RO/ref=sr_1_1?i e=UTF8&qid=1376281905&sr=8-1&keywords=toshiba+1tb+2.5%22
    In the future ALWAYS remember to have 2 backups for everything.  2 backups is 1, and 1 is none.
    That way when something crashes (and they all do).....its no worries.

  • Macbook Pro (mid 2012) Disk Utility can't repair HD

    I have a friend's MacBook Pro in my possession that is not working and has not been used for about two months. After startup, seeing the loading bar, and getting stuck on the spinning wheel of death, I have taken some steps to try to get a boot into Mac OS X. I've reset the PRAM, tried booting in safe mode, and lastly tried to repair Macintosh HD via Disk Utility in the recovery partition. No luck. I get this message after an attempted repair.. "Disk Utility can't repair this disk...disk, and restore your backed up file".
    This is a similar problem to this discussion thread here:
    Disk Utility cannot repair Macintosh HD
    However, in this scenario, my friend does not have any Time Machine backups and would like to recover his files.
    I know that I can re-format and do a fresh install of OS X...but where does that leave me with file recovery?
    Is it possible to retrieve the files at all?
    Any help from the community would be GREATLY appreciated!
    Thanks

  • Disk Utility - get errors and disk utility can not repair, even start ext.

    Hello
    I am using Mac OS X 10.5 on a MacBook Pro intel 2.4 Ghz Intel Core 2 Duo, 2 GB RAM, Intel and Boot Camp / Win XP installed.
    To check my user rights and repair the main HD I have installed 10.5 on my external 500 GB USB 2.0 HD. Started from it and started the disk utility trying to check and repair the Macintosh HD Partition (not win xp). I got following error messages:
    2007-12-01 10:47:12 +0100: „Festplatten-Dienstprogramm“ wurde gestartet.

    Because it can not repair the errors I have started "repair disk". It says "can not unmount Macintosh HD". Even if I have started from the external disk?
    So I get my install CD (Mac OS X 10.5) and started from that. I got the same errors with that disk utility.
    Can someone tell me, if this are "right" errors or do I have to try more to repair this errors? My computer is running fine.
    I am a bit irritated now.
    Best regards

    Way back in Jaguar Disk Utility would pop up dozens of "advisory" messages of no interest nor meaning to anyone except possibly some programmers. This needlessly alarmed regular users. The same thing is happening again in Leopard. The SUID messages are not meaningful nor are they errors, in effect they are announcements that some list being consulted by the utility says one thing, the actual files say something else, Disk Utility is going to assume there is a reason for actual setting and not going to change it, but you (it's kind of assuming you are the programmer) should know this. If the "Die Zugriffssteuerungsliste" is German for ACL (Access Control List) it is the same deal: an ACL was found, but no one told Disk Utility there was suppose to be one.
    If the messages bother you download the whole 110MB 10.5.1 update and run it. It quiets down the output for all the SUID statements save one. Might even shut down the ACL advisories--don't know because I haven't bothered to download 110MBs of updater, I just ran the patch update.
