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.

Do a backup. 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 until you get no errors. See if the internal drive checks good.

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.

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.

Disk Utility Verify permissions question

I have always done, since 10.x, repair permissions via disk utility by opening disk utility app, selecting the top most icon:
"drive manufacturer and size" name
and then underneath: "Macintosh HD"
and then under that "my disc drive" name
I have always just selected the top most and hit repair.
Should I have been actually selecting "Macintosh HD" instead of the top one?

Should I have been actually selecting "Macintosh HD" instead of the top one?
In your case, it doesn't matter. The distinction is only relevant for drives which have two or more partitions.

When i boot i get a flashing folder with a question mark. disk utility doesnt work or read my harddrives to boot with. i installed a new SSD and its not reading that either. i have a macbook pro 2011, any help?

So I came to this problem a while ago. M ycomputer basically froze so I was forced to shut down by holding the button down. When I started it up I got the flashing folder with a question mark. I started it up holding down the command and r keys which brought me to disk utility. Although my computer doesn't read that I have a hard drive to start it up. When I click on the disk utility app, I cannot verify or repair anything either. The buttons won't allow me to click on them. It also shows "Mac OSX Base System" which shows I have files and what not saved. I had been told that I need a new hard drive so I bought and manually installed a OWC SSD 240GB drive and when i booted the computer up it booted up yo the operating system fine with all my files and what not on there. After about twenty minutes, it froze again. I forced a shut down, restarted and the same thing happened. I am not able to choose my SSD to boot up, although thats probably because it doesn't have an operating system installed on it??
i have a Macbook Pro 13" 2011
any help would be great, I'm overall confused.

ryansaint11,
this isn’t Apple support; this is a user-to-user forum. We’re just fellow users of Apple products here.
If you want to boot from your SSD, then you should put the SSD where your HDD currently is, and put the HDD into the optical bay. (That setup will also get you the best performance.) At the moment, you’re still booting from your HDD. Note that you will need to format your SSD in Disk Utility [with the “Mac OS X Extended (Journaled)” format] so that you can install OS X onto it.
Since you have an Early 2011 model, it might or might not have originally come with grey installation DVDs. You will be able to find out whether it did or not by trying to use OS X Internet Recovery to install OS X onto your SSD. If it does not work, or if the installed OS turns out to be Snow Leopard, then it will have originally come with the DVDs, and you should purchase a replacement pair of DVDs from Apple or iFixit; those discs will have your MacBook Pro’s Apple Hardware Test and its iLife apps. If the installed OS turns out to be Lion, then it will not originally have come with the grey installation DVDs, and your Apple Hardware Test will be installed along with Lion, and your iLife apps will be downloadable from the Mac App Store.

Start-Up: Folder with gray question mark / Disk Utility: Invalid Sibling Link

Yesterday, I was working on my computer and it froze up. My only option was to reboot by holding down the power key. When the computer restarted, the screen was all grey with a folder in the middle of the screen with a question mark.
I tried the following:
1) Boot up computer while holding down the "Option" key. - Didn't work.
2) Boot up the computer while holding down the "Shift" key. - Didn't work.
Since the first two options didn't work I inserted the original system install disk and booted up while holding down the "C" key. I selected "English" as the language and then opened "Disk Utilities." I pressed "Repair disk" within First Aid. The message I am getting is as follows:
"First Aid failed. Disk Utility stopped repairing "Macintosh HD" because the following error was encountered: Filesystem verify or repair failed."
The details screen shows the following:
"Verify and repair volume "Macintosh HD"
Checking Journaled HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Invalid sibling link.
Rebuilding Catalog B-tree.
The volume could not be repaired.
Error: Filesystem verify or repair failed."
I ran the "Repair disk" function about 6 times but it was not successful.
I was then going to try to do an "Archive and Install" from the original system disk but when I go to do that no destination options appear at the "Select Destination: Where do you want to install Mac OS X?"
I have not backed up my data very recently (and a lot of what I have stored on this computer is work - I am a freelance designer) so I would like to do something that at least allows me to transfer my data off of my hard drive before reformatting or anything like that. Of course, if there is a less intrusive fix that can leave my hard drive in tact, that would be ideal.
Any advice? Tips? Solutions? I have a MacBook Pro, 15" that I purchased 3 years ago (my 3 year Apple Care plan just expired about a month ago).

You are in a tough situation. The disk appears unusable according to Disk Utility. As was suggested you may (only may) be able to salvage it with Disk Warrior (not sure about Data Rescue). DW can sometimes recover a drive that DU can't. But nothing else can be suggested.
If you can get that disk recovered then back it up ASAP, wipe the disk, reinitialize it, and verify it. But I'm the paranoid type, and with the kind of errors you show for that disk, I am not sure I would ever trust it again. At most I would relegate it to a scratch disk.
Note, if it is a drive that you bought, most drives have a 3 to 5 year warrantee period, so you could get it replaced by the manufacturer if it is within that warrantee period.

Flashing Folder with Question Mark, Disk Utility Grayed Out

I was working on my macbook pro when it appeared to freeze, so I manually shut it down by pressing the power button. When I pressed it again to restart the computer, the restart "chime" sounded, and a flashing folder with a question mark appeared shortly after. The folder flashes for a few minutes, and the macbook turns off again. After consulting the internet, I restarted while holding command+r, and the computer told me to reconnect to the internet, select a language, and so on. When I reached the menu giving me choices for how to recover my information, I discovered that there were apparently no time machine backups recognized and when I tried to use the "first aid" option in Disk Utility, all of the action buttons are grayed out when I select the drives (I'm running OS X Mavericks) at the left, including the "Verify" option at the top. Is there anything I can do? I really would rather not restore a new version of OS X to preserve my information.

Thanks for the response. When I clicked on the option to reinstall, the window asking me to select the disk where I would like to install Mac OS X presents no options. There's just a blank white box with no other messages or prompts.

Disk utility verify

Help!!!
I finally, was able to start my iMac, using safe mode, but it prompt me to normal login, I did not opened only app, and went directly to disk utility...
I choose to verify the disk, but, after some time, it froze, and I can't do nothing (but wait)
So, my questions are:
Does anyone know how long does it takes for disk utility to verify my HD (320 GB)?
And, is it normal that it froze my iMac, to the point is completely unresponsive? How long should I wait in this state, before know something is wrong?
Thanks!

Tony:
I gave up, and decided to erase the disk. But, new issues have come...
I boot from command R, disk utility, erase disk...
First problem, is did not let me select Macintosh HD, appear in light gray color, so I went for the HD with the seria number name...
It has been almost 50 minutes, and all it say is: dismounting disk, so, my question is: is this normal? Should I panic?
I got to a pint were I borrowed a MacBook, so my business can continue working, so, I don't mind wait, but, how much is real wait, and when I will need to do another drastic move.
Thanks!

Disk Utility - Verify Disk (???)

I've got 3 Macs and the same issue is appearing on each. Observation #1 - it is not computer specific.
Here's the question:
In Disc Utility, if I click Verify Disk, I get the beachball - forever. I can use the Tiger install disk and it runs fine (but a p.i.t.a. since my computers are at two different locations). When I first installed Tiger, running Verify Disk from Disk Utility worked fine - now, a beachball on all computers. Why? How can I verify without loading the install disc?
Thanks!!!
PCBjr

Have you just let it run. I have this problem with 10.4.5. If I let it go, for maybe 5-6min it works fine and finishes.
No - after about 3 minutes I get frustrated. When I first went to 10.4.5, it ran like a charm - 30 secs to a minute with NO beachball.
Is this an issue with Tiger I need to avoid?

How to enable disk utility verify/fix permissions

My iMac is running os x 10.6.8 snow leopard.
A month ago the system(software) was re-installed by apple store for a fixing of booting panic.
It's all fine know but I found the disk utility's verify/fix permissions functions were disabled. My question is: what'll cause this and how to enable them?
Thanks

You mean verify/repair disk, not permissions. Forget about repair permissions. It's a waste of time.
As for verify/repair, you cannot repair the volume you are booted from so you need to boot from some other bootable volume. That could be Disk Utility launched on your Installer dvd or a external bootable backup.

Disk utility verify drive error

When I run disk utility I receive the following error. In reading previous posts I discoverd that I needed to use the OSX install disk. So I get it showing in the utilities window on the left side and attempt to get disk utility running by following this path on the disk -- Applications > Utilities > Disk Utility. Double clicking disk utility has no result.
Any suggestions would be appreciated.
The error when running verify disk from disk utility on the iMac:
Verifying volume “Macintosh HD”
Checking HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Invalid node structure
The volume Macintosh HD needs to be repaired.
Error: The underlying task reported failure on exit
1 HFS volume checked
Volume needs repair

As Doug has said, & indeed you have tried....you need to run diskutility from the OS install disk. Or more accurately, you need to run diskutility when booted from the install disk.
The following ( from diskutility help) should explain it clearly.
Start up your computer using another disk.
To use the Install Mac OS X disc, insert the disc and restart your computer holding down the Option key, then select the Install Mac OS X disc and click the arrow.
Open Disk Utility.
If you're using the Mac OS X Install disk, follow the onscreen instructions until the menu bar appears with the Utilities menu in it., and then choose Utilities > Open Disk Utility.
Select the startup disk in the list of disks and volumes, then click First Aid.
Check the S.M.A.R.T. Status at the bottom of the window. If you can't see it, be sure you selected the hard disk your volume is on, and not the volume itself.
If the S.M.A.R.T. Status is "About to Fail," back up your files on the disk as soon as possible and replace the disk.
If the S.M.A.R.T. Status is "Verified" or "Not supported," click Repair Disk to repair the disk.
If Disk Utility tells you to look for links to corrupt files in the DamagedFiles directory, two or more files occupy the same space on your hard disk and at least one of them is likely to be corrupt. Examine each affected file in the DamagedFiles folder, which at the top-level of the affected disk. If you can replace it or recreate the file, delete it. If it contains necessary information, open it and examine its data to make sure it has not been corrupted.
If Disk Utility reports "The underlying task reported failure," Disk Utility encountered a problem it could not repair. Back up as much of your data as possible, reformat your disk, reinstall Mac OS X, and restore your backed up data.

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.

Disk Utility, Verify Disk & Repair Disk unavailable

Hi there!
I want to check my Hard Disk with Disk Utility, but none of the two buttons (Verify Disk & Repair Disk) are available, I started up from my Mac OS X installation disc, and once, it told me that the disk had errors and needed to backup my files, so I went back and backed up with Time Machine, then out of curiosity went again and I started up from my Mac OS X installation disc, and this time it told me that the disk was fine and there wasn't any errors, but when I open Disk Utility with my Mac, none of the buttons are available, is this normal?
What should I do?
Context: Before all this, I installed a program called Tuxera to create a NTFS partition but my Mac started to act weird, so I deactivate and uninstalled this program, that's when I went to verify the disk.
Any Help would be gratefully appreciated

I hope I'm wrong but it sounds very much like Tuxera did something to your startup disk. I would also be somewhat concerned about the integrity of any Time Machine Backups you made after you ran Tuxera.
The safest thing to do would be to start up from your Snow Leopard disk and see if you can *restore your system and data from your Time Machine backups to an +external HD+* formatted using Mac OS Extended (Journaled) and GUID Partitioning. Formatting will erase all the data on that disk. *If you try to restore to the internal and it doesn't work you will probably lose most of your data.*
Startup your Mac using the external and check very carefully to see that you have all your data and that everything works as it should. If it does you can safely reformat your internal drive from Disk Utility on the Leopard disk using Mac OS Extended (Journaled) and GUID Partitioning. After that you can clone the external drive to your Mac's internal drive or install from the Time Machine backups.
If the Time Machine backup doesn't work you will need to run a disk data recovery utility to see if you can salvage your data from your internal drive.
I don't use PC's so someone may be along with much better advice. However, unless and until someone more knowledgeable about PC file formats comes along to help *don't reformat your internal drive until you know your Time Machine backups are OK.*

Question about Disk Utility

I migrated my IMac I got back in May to Leopard and I was looking at the Disk Utility and noticed the Repair Disk option is the only one grayed out. Does this mean my hard drive needs a repair done on this? Tonight I got prompted to update my Keychains with a new update and rebooted. Is there a diagnostic mode where I can get this option? Do I have to put in the Mac OS X dvd in to get to a repair option?

You should never be without a 2nd "emergency" boot drive with current version of OS X, because Disk Utility does change. You can verify, but it isn't reliable.
You can also run repairs from Single User Mode (command S, follow the onscreen instructions at the prompt) to run FSCK -FY.
It is easy to use Leopard Cache Cleaner to do the above also. It would be nice to "schedule" the system to do a system check and repair on the next startup.
A lot of people don't trust Disk Utility and use Disk Warrior, there are errors that DU doesn't see, and doesn't fix. And you won't know if you don't have DW and an alternate boot drive.
