Disk Utility can't repair my drive? What to do now?

Hello all, I am in a midst of trouble where disk utility is failing to repair the drive. It gives me message '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". Now, what should I do?

Is this a good question?

Please give us the last three figures of your serial number. I would drag off as many files as possible BEFORE attempting a disk repair as you may try to repair the disk and then find it unmountable. This may also be a bad HD/IR cable problem and can destroy the hard drive.

TechTool Pro can repair when Disk Utility can't. TechTool De Luxe used to included with AppleCare, but Apple ceased doing this quite a few years ago. However, you can still get TechTool Deluxe free from : http://download.cnet.com/TechTool-Deluxe...

Boot the Mac into Single User Mode by holding down Command+S during system boot after you hear the boot chime, you know you will have successfully entered Single User Mode because you will see a bunch of white text on a black background scroll by

When the Single User boot sequence has finished, you’ll find a small command prompt at the bottom of the screen prefixed by a hash sign (#), when you see that type the following command exactly:

fsck -fy

Once fsck completes, if you see a “File system was modified” message, then you should run “fsck -fy” again until you see a message stating “The volume (name) appears to be OK” – this is standard procedure of using fsck

Type “reboot” to leave Single User Mode.

If you receive this message from Disk Utility after replugging an external drive that wasn't successfully ejected (or unmounted), it could be that the OS is already busy performing the repair in the background. Your Mac will not be able to mount the disk until after the automatic checks are complete.

If the external drive's activity indicator is blinking, but you are otherwise unable to access the drive, then some background process is working on your disk. To see whether this is the case, you can run the "process status" command in a Console shell:

Macbook-Pro: ~ luthien$  sudo ps ax | grep hfs

605 ??  R  4:08.59 /System/Library/Filesystems/hfs.fs/Contents/Resources/./fsck_hfs -y /dev/disk4s4

In my case, my external drive (which I use for Time Machine backups) was given the name "/dev/disk4s4", and indeed the filesystem check program (fsck_hfs) command was still running. I let it do it's thing for a few hours; when it was done, the disk was automatically remounted and could be browsed in Finder.

If nothing above helps remove the HD and plug it into another machine like external and get your files. After that put it back into your Macbook. If you have bootable drive with osx - if not make one- and on start up press cmd. Boot the Mac with osx and go into disk utility to format it and install new os. Voila!

How do I run the "process status" command in a Console shell?

by

Open Applications -> Utility -> Terminal. Then type in

sudo ps ax | grep fsck

and press the Enter key. If the command prompt returns without any output, then the drive isn't being checked by one of the "fsck" programs (filesystem check). Otherwise, if you see a line like the one above, then the drive is busy.

Can you still eject your Hard Drive, even though you received the message while you plugged it into your Mac?

The reason why I am asking is because I usually eject my HD by dragging it to the trash icon. Even though I did it, my Mac claims that it wasn't eject properly. Then when I plugged it back in, then I get, "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".

Hi L.D.

Your disk has file-system corruption (directory structure) and Disk Utility won’t repair it. The challenge is to backup such disks. Are you able to create a disk image of the drive using Disk Utility? If not then try the method suggested by CarlFitzpatrick.

Hi timmcculum,

In Mac there are several errors which is difficult to cumbersome whenever they encounter and “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.” Is one of the most common error which occur when you use Disk Utility in a bid to solve a problem and Disk Utility has shrugged its shoulders and given up.

So, if you are facing this issue, then try below mentioned few tricks: -

1.Backup Mac OS X:

Before you do anything, makes sure you have proper Mac backup available on an external drive, which can come handy in case of data loss situation. For backup, you can either use in-built Mac software like Time Machine or 3rd party tools like Stellar Drive Clone, Carbon Copy Cloner, etc.

2.Attempt the last ditch repair:

Do a last minute ditch repair, by booting your Mac OS X before the Apple logo will appear by holding down the Cmd+S button from your keyboard.

Now, release it when the boot progress bar indicator will appear. This will boot you into Single User mode and things will suddenly go very Linux, with a text-based display. Here, you don’t need to panic. Just wait until the flashing text cursor appears and type the following command:

/sbin/fsck -fyd

If you see the following message at the end of the repair:

  • FILE SYSTEM WAS MODIFIED *****

… then type the command again. Repeat another two or three times until you have a message similar to this returned:

  • The volume appears to be OK

Of course, you may never see this because even this trick might not be able to fix your disk. However, you might be able to make note of its output and do a quick Google search to check a solution of this problem.

When you’ve finished in Single User Mode, type the following to reboot:

reboot

Note that you might not be able to enter Single User Mode if you have a firmware password set. You’ll need to temporarily disable it for further use. Additionally, on a Retina display the text will be tiny – but still readable if you move closer to the screen!

3.Final solution (use a commercial applications):

Here, you need to use some 3rd party commercial applications like Stellar Volume Repair Software which might be helpful in repairing disk permissions and also solving your issue.

I have decided my four year old Seagate 1TB drive has died, unfortunately it is my Time Machine.

So with a new 2TB Seagate drive (remembering the original question of this string) will 'restore' in fact restore all my time machine 'saves' as well as the other files I have backed-up to this 1TB drive.

Nobody is answering the question. How do you get files off of a drive that won't boot? The message says to back up your files, but nobody here is explaining how to do that.

If you have a PC and an external hard drive enclosure or a hard drive base reader the you could slap the hard drive on it and fix it with the PC. Or at least read the Hard Drive to copy the files of the Hard Drive. That is if the drive is not fully shot.

by

You can also buy an USB adapter to plug into the hard drive, and if the drive is readable, you might get a chance to save your files. You can accomplish the same thing by opening your PC and plugging the drive into a 2nd connector if available. I can't see the whole thread, and I'm sorry if you have a Mac. Opening these can be an adventure, and I don't think TestDisk will run in this case.

If you're adventurous and have a PC, you can try TestDisk, a little utility that has been able to get into a couple drives when nothing else I've tried has been able to.

The bottom line, however, is that the life expectancy of a hard drive is 2-4 years on average (Google), and the undeniable fact is that it will fail catastrophically at some point. A good clean room/data recovery service may save your data, but it will cost. Perhaps you've hit that wall. Perhaps it's worth it.

Hi boxmanboxman2...

To recover files from a non booting Mac, one has to first boot the Mac with a secondary source say a rescue media and recover files from the Mac internal hard drive.

This happened to me, too. I ended up getting a CrashPlan account and have backed up the files I can to the cloud. Fortunately, I also have the same files on my Mac, so I've backed those up, too. I'm getting ready to reformat the bad hard drive, so I'll see if my time doing so was a waste or if the drive is again useable. Might be a win-win in that I have my stuff backed up in three places, but if the drive is bad, I still have the cloud and another external drive.

^^My comment is assuming you got the error from an external HD, of course.

Same issue. Hard drive failed completely. I'm not going to be able to access with anything. I don't have a DVD with the OS. My guess is that I need to install a new drive, download a new OS, and install it.

My only Mac is dead. I don't have access to anything but a Windows PC. How do I download and install OS11 to my Mac with the PC? I do have a FAT32 USB.

How?

You need to be able to burn a OS install CD from an ISO file. You can purchase a OS from many websites like this one.

Then get a new HDD in your Mac and install the OS.

by

Thanks. That's what I ended up doing. Actually I bought a bootable USB drive ($15) with OS11 on it. Frustrating. If the OS is available for free, seems like I should be able to just download the ISO file and burn it (for free). And it also seems like most folks who want to help just can't believe that the failed drive is totally useless. Lots of help available to recover it, but they are often simply dead. I appreciate your advice and the trouble you went through.

by

Sadly, you encountered the Chicken & Egg problem ;-}

You need a system running OS-X to create a bootable disk. Think of it this way if your Windows systems drive failed you would be in the same boat! As you couldn't create a bootable disk for Windows under OS-X natively.

I have seen this quite often. What I do is plug the drive into ubuntu and copy the files to an external. You have to run the command: 'gksu nautilus' to be able to access the files due to permissions.

I think staying with an OS-X system would be a lot less work here. Besides ubuntu does not support Apples file types and permission mask so you would loose that.
