OS X V10.7 Lion :: How To Use Disk Utility To Repair Encrypted Disk Partition
Apr 6, 2012
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 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.
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 am trying to repair my disk so I can install bootcamp, but when I reboot my machine and run disk utility and choose repair disk, it hangs. Does anyone have any ideas ?
Running Diks Util on my iMac 10.6.2. i am given this warning. ========= Warning: SUID file "System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAgent" has been modified and will not be repaired.
Is it something I should heed and what to do in that case?
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 am having problems with my Mac running slow. I had a friend guide me to run a "repair disk permission".I did that but I am not sure if I am to click clear history.Also should I do anything else to help my Mac run better?
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 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.
I ran installer then went to disk utility and pushed disk repair. it ran and indicated in green that no repairs were necessary. i then went to startup disk and only the Diks and network startup showed up but no hard drive. i also open computer to make sure was not wet muddy due to leak in cooling system but all was dry
I have an external WD drive in a self-enclosed case, both purchased from OWC, used for my Time Machine backups. The disk and backups have been running just fine since I began using this disk over a year ago.
When I plugged in my disk yesterday (USB), it didn't mount. I ran Disk Utility on my 'Time Machine' partition, starting with verify disk. It reported that it needed to be repaired. When I run repair, it runs for several minutes and I see information of what is being done -- incorrect block count for file shutdown_time, incorrect block count for file permStore, etc -- but I always ends with "Disk Utility can't repair this disk" and that it needs to be reformatted.
I've run Repair Disk multiple times, all with the same answer so it seems running it again won't change the problem. Reformatting and starting fresh with Time Machine seems to be the only course of action
What specific issues should I be aware of as I reformat my Time Machine drive/app partition?

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?
I'm experiencing some problems with my iMac right now, and I'm not sure how they started or what to do to correct them.
1) Computer seems to hang up from time to time while starting applications, or in the middle of some tasks. There's no rhyme or reason or any patterns.
Question: Is there anything I should try to clean up the computer?
2) About a week ago I started using Time Machine to do scheduled backups rather than me manually starting my own backups. Now whenever time machine does a back up, it seems to stop working somewhere in the "Preparing to Backup" stage, and I end up needing to restart the computer manually because the whole system becomes useless. It will no longer complete any backups, even when I start manually.
Question: Why would time machine now all of the sudden start freezing in the middle of the prep to backup stage?
3) I just tried to use my disk utility to check and see if I need to repair the disk and here is what reported back:

I have two drives. The main internal drive is giving me this message after I tried to repair it.The external drive that TM backs up to says the volume appears to be ok..What do I need to do to restore my system and not lose all my pics, home movies ect.Read a lot of posts, but I must admit they were a little advanced for my knowledge.
I had windows vista installed but suddenly the audio decided to become faulty, after spending a day trying to fix it i realized I have a windows 7 install disc so i might as well just replace vista with windows 7. I didnt take care of vista or ever register it so it became quite a task to upgrade so i just deleted the partition and went to create a new one and just do a full install of windows 7.
I made the partition but the wrong format, so i removed it through boot camp assistant and created another, except now it keeps giving me the "back up the disk and use disk utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using boot camp assistant again" Now, I'd love to do this, except I have no idea what I'm doing and WHY this error has occured. After becoming frustrated I switched from my imac to my macbook pro and received the same error when trying to create a partition. So any help on exactly what I need to do would be a HUGE help. I only use windows for music production (I know, seems backwards, but I use Sony Acid and FL Studio so I'm stuck with Windows)
I have the "show detail" box checked but Disk Utility is not showing detail.It goes through verify and repair, says it is finished, but shows no files. I have never had No files need repair.My computer has been slow and erratic and usually running Disk Utility works, but not now.
Anyone knows why my external HD (USB disk connected to Airport extreme) does not show up in disk utility? (It sits on my desktop just fine and is fully functional) I' want to erase a partition but now i don't know how.
I have a Time Machine a a multiple partition. The TM disk didn't properly disconnect and now have disk error. I'm repairing disk through Disk utility. It's taking forever to fix. The drive is 400GB.I can stop repair but it's been repairing for an hour.
My new 2010 hexacore Mac will have 24G memory, an OWC Extreme Pro 120G SSD (positioned in the lower optical bay) and four 2TB WD RE4 drives. I'll use my old Synology 209 NAS (two 1TB WD Green Raid 1 drives) for TM backups over 1000Mbps Ethernet. Yes, I'll need to upgrade to a larger NAS very soon. This will be my first Mac Pro (have MBPs and iMac) and will be used for web design and development (mostly Adobe CS5 products).
The SSD will be used for boot and application files. I plan to use Disk Utility to create a 1+0 Raid array for data files. For a Scratch disk, should I: 1) create a partition on the 1+0 Raid Array for Scratch 2) partition a chunk of the SSD for Scratch 3) attach a spare external 2.5" WD drive via Firewire 800 for Scratch
Based on my reading, it seems that option 1 makes the most sense but I'm not entirely sure if you can partition a 1+0 array with Disk Utility. I'm pretty sure option 3 is quite silly but wanted to toss out the idea. Lastly, are there any generic recommendations on scratch volume sizing?
I have a 640GB external USB hard drive that I use for time machine currently. I would like to go in and add a partition to load movies to and plug it into my PS3. Can I use disk utility to create a new partition without erasing the stuff already on the disk?
And then is it possible to format a partition larger than 32GB as FAT?
after i erased the partition in the list in left i couldn't delete a partition in disk utility "File system resize support required, such as HFS with Journaling enabled" error, i think it came with REfit program!?
I installed Ubuntu on my Macbook but it didn't really work for me so I deleted it. I used Disk Utility to delete the Ubuntu partition, but when I want to delete a Linux-swap partition I made while installing Ubuntu nothing happens. I press the minus button and it will delete it. But after deleting it just stays there, and I can't change the partition in any way. How can I delete the partition?
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 live in France and my nearest authorized dealer is 200 miles away, so I've been on the phone with support a couple of times and gone through various hoops.
Two days ago, my hard drive (or CPU?) started acting up. My Macbook Pro (bought May 07, 2.16 GHz, running 10.4.11) took a long time to boot, and then my desktop image appeared as a fragment along the top of the screen. Various processes started to hang the machine, during which time a repetitive sequence of ticking could be heard from inside the machine until whatever was wrong resolved itself. There were no program crashes and in fact the machine operated fine inbetween these hangs. I ran an extended hardware test, no problems there. Disk Utility, however, would not complete its verification, saying "the underlying task reported failure on exit". It stated that the HD needed to be repaired. However, the "repair disk" button was greyed out, disallowing the repair.
TechTool showed the directory scan failed, as did the volume structure test.
I tried numerous times to Safeboot, but the computer crashed (simply turned off suddenly) midway into the boot each time.
Apple Support had me zap the PRAM, clear the caches, and do that 15-second power-button thing with the battery out. All the log-in items that might have been slowing the boot were removed. This succeeded in getting the machine to boot faster and the desktop image returned.
However, both Verify Disk and TechTool showed the same problems, saying the disk needs to be repaired.
I have since backed everything up and would like to try to resolve this myself rather than driving it to the service centre. What are my next steps? I'd like to somehow avoid a clean install and have to reload everything
I have a 10 GB encrypted disk image on my macbook (type OS Extended (journaled)). I've pretty much filled up the space so I want to resize. I go into disk utility with the disk unmounted and 'Resized' it to 20GB. Then I mount it and go into the Partition tab. I drag the corner all the way down to fill up the space and hit Apply. It goes through the motions without error but it does not actually extend the partition to the resize. On the right next it then says something to the effect that the disk is read only and cannot resize the partition. The write status is read/write until I click apple....then it switches to 'Unmounted, read-only'.
