Disk Utility Verify/Repair options
When I Verify my HD in Disk Utility I get this error.
Why does it say this? Should I Repair the disk? Will I lose data? Any help thanks!
You will need to repair the HD per the instructions, this is critcal. Prior to doing this backup your computer, that should be your #1 priority!! To repair the HD, restart the computer, when you hear the startup tone hold down the Option Key and select the Recovery Partition. Open Disk Utility, select your internal HD and run Repair Disk. If the disk has error run Repair Disk 2-3 times, if errors continue your have a damaged HD that needs to be replaced.

Question on Disk Utility Verify
I have a two-week old 27" iMac, 1 TB SSD, 32 GB RAM, 1 4 GB RAID-0 external G-Drive (external Max OS drive), 2 4 GB external G-Drives (1 used as partitioned backup (1 TB for Boot Camp, 3 TB for Time Machine), 1 planned for Windows external drive). I also bought and installed the Paragon NTFS and CampTune applications.
Have setup Boot Camp on the internal 1 TB SSD (127 GB partition) and finally got things to work, but, I am continually having issues with WIndows crashing (either in the middle of use, or during startup or shutdown with the KERNEL_SECURITY_CHECK_FAILURE. I have been Googling, and this seems associated with the use of external drives?
The last time I got this, I was unable to boot back into Mac partition, and ended up having to hold down the Option Key at boot, and select the right partition to boot from, I then started verifying all my drives and paritions with Disk Utility, and was finding and repairing various issues (everything seemed to repair fine) and also the Mac HD partition seemed to have Permissions issues, which seemed to repair fine.
But, in the process of doing this, am noticing an issue, or at least a difference between the Mac HD and and the External Mac-formatted Verify logs. The External drive ALWAYS tells me the drive is good, while the Mac HD has done that only once, and usually seems just to stop with "Checking Volume Information" as the last entry. Not sure this is an issue, or not, but was looking for ANY cause for the continual Windows issue.
Disk Utility Log Dumps are below, first the internal Mac HD (two partitions, Mac and Boot Camp, checking only the Mac partition), second the External G-Drive, formatted Mac RAID HD. Both times, I am selecting the drive partition below the actual physical HW.
The Boot Camp partition checks good.
Thanks.

Quit Disk Utility while repairing
I quit Disk Utility while repairing or verifying. I accidentally hit ok when the dropdown said something like "are you sure you want to do this, your mac software may be damaged" Now many of the applications look all glitchy. They still function, but there are boxes around buttons, textures have been changed and it generally looks bad. What do I do? I've tried reparing and verifying again but nothing helped.
Boot to the Recovery Volume (command - R on a restart or hold down the option key during a restart and select Recovery Volume). Run Disk Utility Verify/Repair and Repair Permissions. Then reinstall the OS.

I followed all of the directions after seeing that my laptop flashed the folder with the question mark. But when I went to disk utility to repair/ verify issues w/ start up disk it would not allow me to. The buttons to repair and modify we're there but they were grey and couldn't be pressed.
Were you trying to repair the disk you were booted from? You can't do that - you need to boot from your install disk, and choose 'Disk Utility' from the 'install' menu.

Disk Utility - Verify Disk Permissions / Repair
I run Disk Utility > Verify Disk Permissions with this rsult:
Verify permissions for “Macintosh HD”
Permissions differ on "usr/share/derby", should be drwxr-xr-x , they are lrwxr-xr-x .
The following repair was successful.
A few minutes later I run Verify Disk Permissions again with the SAME result:
Verify permissions for “Macintosh HD”
Permissions differ on "usr/share/derby", should be drwxr-xr-x , they are lrwxr-xr-x .
What does it mean and how can I stop this error?
Thanks!There is nothing in that message that requires repairing. That is why it keeps showing up.
The permission database has to be updated every time the system is updated. If they miss a change that they have made in the system, it will get flagged as you see, but doesn't mean anything is wrong.
That KnowledgeBase article also must be updated to reflect the things they missed.
All that message is saying is that the directory derby is now replaced with a link to another directory (the l vs the d). However, mine doesn't have a link. Did you install anything that might have updated derby?
If you open Terminal and enter this code, can you post the line that has derby on it?ls -al /usr/share/
I'm repairing permissions now to see what pops up for me, but that will take a little while.
Edit: I looked into the Derby directory and Derby is a Relational Database Management System used by Apache. So, did you install something that modified Apache, PHP, mySQL or something like that? It might have altered the link.

I had to restart by resetting the NVRAM/PRAM. Now I have a window showing OS X Utilities. My options are restore from Time Machine Backup (which I could do), Disk Utility to repair or erase, get help online or reinstall OS X. What should I do? The problem began when I tried to restart my computer and the only thing I saw was the grey screen, Apple logo, and the timer; the computer wouldn't restart from there.
I searched through trouble shooting options on the Apple Support page and was able to make it this far.

Disk Utility verify or repair permission runs but doesn't indicate anything
Recently I ran Disk Utility to repair permissions after a software upgrade and the utility ran and ran, but no permissions were repaired and the utility didn't stop running. After an hour, I stopped running repair permissions. Does this indicate something remiss about the utility? Or worse? What should I do about this?
You might want to boot from your OS installer disk and launch Disk Utility. Repair Disk from there.

DISK UTILITY STOPPED REPAIRING MACINTOSH HD!
So initially, my mac just was stuck on the white screen with grey apple logo and the spinning wheel. It wouldn't move! So I held down the power button and turned it off, let it rest for good 8 hours, turned it back on and it was still the same! With the help of some online postings: command + control + p + r, I got to the Disk Utility page and I tried checking for any damage. For most part everything was"ok" or "clear"! Then I ran 'VERIFY DISK' for MACINTOSH HD and some problems occurred. I clicked on 'REPAIR DISK' as promted. It said "DISK UTILITY STOPPED REPAIRING MACINTOSH HD: Disk Utitlity can't repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
I HAVE ABSOLUTELY NO IDEA HOW TO DO THAT ! I have not backed up a single thing on my mac!If you want to preserve the data on the boot drive, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data, you can skip this step.
There are several ways to back up a Mac that is unable to fully boot. You need an external hard drive to hold the backup data.
1. Boot from the Recovery partition or from a local Time Machine backup volume (option key at startup.) Launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
2. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
3. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data. -
Disk Utility stopped repairing Mac HD - Now what?
My computer has been running slow so I cleaned up my desktop, trashed a bunch of old files and went to verify permissions. I was then told to use disk repair.
In the middle of doing so I got this message - "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."
Besides occasional slowness, my computer is working fine and I was able to get back to my desktop. Is this slow down issue going to get progressively worse if I don't reformat the disk? Should I do what the message says? If so, how? I've never reformatted before...it sounds a little scary.
I back up about once a week (just did so this morning) so I should be good to go there. I have AppleCare. Is this something I should bring the computer in for or can I fix this issue on my own?
Thanks in advance for any help.Do as instructed. Get your self a backup drive if you don't have one. Backup your files. Then erase your OS X volume and reinstall Mountain Lion.
Install or Reinstall Lion/Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your startup volume (usually Macintosh HD) from the
left side list. Click on the Erase tab in the DU main window.
3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
the Security button and set the Zero Data option to one-pass. Click on
the Erase button and wait until the process has completed.
4. Quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion/Mountain Lion and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
because it is three times faster than wireless. -
have a mac book pro that crashed. ran disk utility to repair. comp booted and ran for short time. then crashed. ran repair again. disk utility said it could not repair disk and needed to format and start again.
comp said it could not unmount disk and now when comp trys to boot all i get is a question mark on the screen. helpErase and Install
1. Boot from your Snow Leopard Installer Disc. 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.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Quit DU after formatting completes and return to the installer. Install Snow Leopard.
5. After restart into Snow Leopard download and install Mac OS X 10.6.8 Update Combo v1.1. -
How to use disk utility to repair an encrypted disk partition
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?Yes...
Actually I gave it another try. I discovered that by right-clicking on the partition it prompted me to unlock the volume. After entering my password I was able to run the repair.
All solved...! Thanks for visiting my Q all the same. -
Disk utility verify comes back with a errors.
I am running Mac OS X 10.5.8.
When I run the disk utility verify it comes back with a message saying that it cannot repair the errors found on the drive. I also get msgs that the file counts and directory counts are not what they are supposed to be.
What do you recommend I do? Are these errors serious or should I ignore them. I only noticed these errors yesterday after my computer would not boot. I had to actually take out the power cord from the back of the computer and hold the power buttom down for 20 secs and then reattach the power cord. Only then did it boot again.
I am thinking about doing a complete reinstall from scratch however, there may be a chance that some other disk utility out there can fix my problems....any ideas?
Thanks in advance for your help.Since your system is having trouble booting, you should probably fix those errors.
When Disk Utility can't repair a problem, you have some choices. Many people buy Disk Warrior or TechTool Pro, with Disk Warrior the preferred program, to fix those sort of errors, assuming they aren't caused by failing hardware. Those sound like 'soft' errors that Disk Warrior can repair (see their web site).
If you want to check your hard drive hardware, you can run the Apple hardware test (run the extended test), and SMART Utility is another program that will give you insights into the health of the hard drive.
If you have a good backup, another option is to boot to an OS X DVD (or a bootable backup), use Disk Utility to erase the hard drive and write zero's to it, then restore your backup. If you go this route, make sure you have a good backup because you'll be erasing, permanently, everything on your hard drive. -
Time machine backups are failing. I've followed the instructions I found on the Time Machine troubleshooting page (http://pondini.org/TM/Troubleshooting.html) but have gotten to where I don't know what to do next.
Sequence of events:
The main error message is always:
An error occurred while copying files. The problem could be temporary. If the problem persists, use Disk Utility to repair your backup disk.
Yesterday, I opened Disk Utility and verified the disk. Got this error:
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 OS X Utilities window appears, choose Disk Utility.
I ran Disk Utility and repaired the hard drive. Then I manually started the backup before going to bed, figuring it was going to take a long time to run. When I got up this morning, the backup had failed with the same "could be temporary" error. I checked the log, which says:

Does anyone know what the problem is here and what I should do?
Thanks,
TeryYou have repaired your boot drive (which is good) but have you repaired your time machine drive? I don't own a Time Capsule so I don't know if disk utility can operate on it. If it can, you should repair it as well. You may need to erase it and start a new backup. That happens to time machine volumes from time to time and is why people who are serious about their data never rely on a single source of backup.

Disk Utility stops repairing Time Capsule backup with no info
After having problems backing up to a long-term stable backup on TC, I have tried using Disk Utility to repair the sparsebundle.
The repair begins, but never finishes. And no details are left in DU to decode what happened.
Does this mean sparsebundle corrupt? Or a problem with DU?Sugith Varughese wrote:
Wow, DU by ethernet IS much faster than wireless!
Unfortunately, DU said the sparse bundle was okay, but when I tried another TC backup, it failed again.
I assume this means there's no option but to delete the sparse bundle and start again?
No. There may be nothing at all wrong with the TC or sparse bundle. We need to know why it failed. Without the actual message(s), we're shooting in the dark. Start with #C2 in Time Machine - Troubleshooting. It will show you how to locate the message(s) that describe the problem, then help you fix it.
If that doesn't help, post back with details, including all the messages, your setup, what you've done, and the results. -
