DiskUtility (Lion) 'skips' a RAID0 disk verify/repair

Hi,
I have a pair of 500GB disks set as RAID0 on my Mac Pro (3.1) running Lion. I suspect they may have some corruption so I tried to run the Disk verify tool. When I click verfiy or repair the progress bar flashes up momentiarly then disapears and no output is given. It works fine on my other (non RAID) disks.
I ran FSCK_HFS off a LION book USB stick and that works, but the disk util doesn't verify regardless of how I have booted.
Should I be concered? I am sure it ran ok before when I had SnowLeopard loaded.
Also, I want to add a 2nd RAID0 set to this Mac Pro. Currently the 2 500GB disks are in bays 1 and 3. Can I move them to 1 & 2 without breaking the RAID?
Thanks
Simon

Disk Utility striped RAID Verify is fixed in Mountan Lion (OS X 10.8).

Warning after Disk Verify/Repair

I just completed a disk verify and repair.
At the end of the process I got the following message:
Warning: SUID file "System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAg ent" has been modified and will not be repaired.
What does this mean? Is there any significance? Do I need to fix this?

Ignore it. It's a common message not an error. It's innocuous.

Should I do a disk verify/repair before installing Lion?

If so, how? And is it risky to such a procedure?

Repair the Hard Drive and Permissions
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. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
It is not risky.

DIsk verify/repair not working

My computer seemed a bit slow and slightly erratic so it seemed time for a rerun of disk utility. Disk repair ran so far, then exited leaving an error message: 'The underlying task reported failure on exit'. I tried verify, then repair permissions, both stated "No valid packages". So I then started up with install disk and Disk Utility ran repair successfully - but verify or repair from the CD still gave 'No valid packages' Can anyone tell me what this means and what I should do?
The machine still seems to start and run OK. My 60Mb disk has about 8.5 Mb free. Is this insufficient and has this affected anything.
Thanks for your potential contributions all you experts out there.

The machine still seems to start and run OK. My 60Mb disk has about 8.5 Mb free. Is this insufficient and has this affected anything.
I assume you mean GB, not MB. 8.5GB is kind of getting down there for Tiger and could have contributed to this, especially if the disk has been in use for a long time with large files and files may have become highly fragmented.
If Disk Utility won't repair a volume you have two options.
One is to copy off what files you can (bearing in mind that your directory has errors so it may not 100% know where all the bits and pieces are to all the files). Then erase the drive, reinstall the operating system, copy files back on.
Another is to buy a utility such as Diskwarrior and let it rebuild the directory. This will be a lot faster, but will, of course, cost about $100 for the software. Other software packages (TechToolPro, Drive Genius, etc.) may be able to do the same. DW is a one trick application but is probably the best at what it does.
Many say keep 15% of your drive free at all times for OSX to have room to run. With a 60GB HD that's only 9GB (which is why I don't like that "15%" recommendation since on a 2TB drive that would be 300GB which is ridiculously large). I check my virtual memory use in Activity Monitor and see that for my computer this is usually 6GB. I figure maybe 3x that is good for wiggle room and try to leave 18GB free at all times.

My Mac OS Lion 10.7 FileVaulted HD does not boot, prohibitory sign, stop sign appears some minutes after boot starts. Disk Utility repair shows four error messages:

I suppose it is serious bug in Mac OS Lion managing FileVault and wonder what the help could be?

Most likely culprit is your Lacie drives which are notorious for flaky power supplies which cause just the sort of erratic behaviour that you describe. Have had similar issues myself. Lacie has been good about replacing my power converter-- twice. If you have seven of them, good luck finding the bad one or more. Like I said, the behaviour is erratic. Sometimes it'll work sometimes not. I can't comment on Samsung drives because I've never used them and have never heard anything about them. Same with Softraid. Why not just use Disk Utility. Sounds like you're ready for an external hardware raid. This will be much faster, much more reliable, and may even be cheaper than seven firewire drives. Check out G Tech, and Maxx Digital for starters.
Best of luck

Disk utility can't verify/repair partition map.

When trying to verify/repair my hdd it gives me the error: "Error: Couldn’t find the target disk for this operation."

You should already have a Recovery HD that was created when you installed Lion or came with the computer pre-installed. The Recovery Disk Assistant simply makes a Recovery HD you can use if one is missing from the hard drive.
However, repartitioning will destroy all the data on the drive so you will have to reinstall Lion. It will also remove the Recovery HD from the drive, so you will need to use your flash drive Recovery HD to boot the computer and get to the recovery main menu. The essential process:
Install or Reinstall Lion from Scratch
If possible backup your files to an external drive or second internal 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.
You will need to use the OPTION boot method to select your recovery flash drive as the boot volume.
Repartition the hard drive:
Select Disk Utility from the main menu and click on the Continue button.
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.
Select one partition from the Partition Scheme dropdown menu. Click on the Options button and 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.
Quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion and click on the Continue button.
When the destination drive is displayed click on the Display Other Drives button and select your internal hard drive as the target.

Verify/Repair disk permissions hangs

Hello,
Since yesterday my SL became kind of unstable and I have to reboot it because of a hang with a spinning wheel quite often.
I want to verify/repair the disk permissions but the tasks never completes. When I run it via the GUI in the Disk Utility, it goes to around 5% then nothing happens even if I wait several hours. I can cancel the repair.
I also tried to run it via the command line but the progress stays at 0% :
~ $ sudo diskutil verifyPermissions /
Started verify/repair permissions on disk0s2 Macintosh HD
0% ...............................................
~ $ sudo diskutil repairPermissions /
Started verify/repair permissions on disk0s2 Macintosh HD
0% ...............................................
Any ideas ?
Thanks,
Tex

From your description it sounds like the internal HD is failing. It should be under 1 year old so you are covered by the warranty, make an appointment ASAP with your local Apple Store or AASP to bring it in. In addition if you have not purchased AppleCare now is the time to get it, AppleCare will extend your warranty to 3 years. However you must buy it buy it within the first year of ownership!
Here is a link you can use to make an appointment.

"Disk not readable...", Verify & Repair fail, Zero Out, HFS+ still fail

First, a time machine error came up saying the volume could not be found. Tried disk verify, disk repair (in disk utility) restarting, reconnecting, but to no avail. On restarting, computer says "Disk was not readable by this computer." I then Zeroed out all the data and reformatted the drive to Mac OS Extended (Journaled). TM worked for most of the day until tonight when another error message came up saying that the next backup failed because it required 168GB, but only 49GB was available. Yet I had done virtually nothing since the last backup the hour earlier. I clicked "Back up Now" to try and get it to maybe re-evaluate the situation and maybe do the backup, but instead, I get the error that I got before - "The volume could not be found" (or something to that effect). Upon restarting, I again get "The disk you inserted was not readable by this computer".
Is there something I am doing wrong? What can I do to fix this, or prevent this from happening later?

This is what the error message was before, and is what it is now.
You had these sorts of errors, then zeroed-out the drive, now you have them again?
There's only one conclusion: your drive is failing. They don't always just crash and burn.
Note that the volume name should be "Time Machine", but Disk Utility sees it as "disk2s1" for some reason.
That's it's internal name to OSX. Use +System Profiler+ (Apple menu, +About this Mac,+ then +More Info.+
Look in the sidebar for FireWire or USB (whichever it is), select it, and you'll see disk2s1 listed as BSD name.
Time Machine Buddy seems to freeze most of my other widgets (can't type in calculator, can't delete Time Machine Buddy). It doesn't seem to do anything either, It just sits there saying "Backup Status" and "Messages" but no messages, just "....".
That's not normal, if you've had a successful backup recently, or one currently in progress.
An earlier post had a similar problem, because somehow he didn't have permission to read his own system log. From the Finder menubar, select Go, then +Go to folder,+ then type /var/log
That should list, among other things, system.log Double-click it. If nothing shows in the center portion, post back and we'll fix it.
But your main problem is an unreliable drive.

There are no ticking noises coming from the hard drive, and it lights up still, and i have tried replacing the cords, and restarting/shutting down the computer, and have tried it on a mac desktop also - same problem.
Any help would be great!!!

Try this on one of the Macs ...

Is there a document that explains the differences in these two actions?
Thanks.

Hi Trevor,
Repair Permissions and Verify or Repair disk are two separate processes.

Airport Utility says "Internal disk needs repairs".

I've had my Time Capsule for quite a while, and never had any problems with it. I keep my iTunes library on it, which is around 130GB of music. Recently, I had my iPod that held all my music had a hard-drive problem and I had to get it replaced and haven't received the new one yet. So the only place my music library is is on the Time Capsule. Lately it had been giving me problems while I was copying files in iTunes to it, and would disconnect in the middle, but when I unplugged it and plugged it in again (resetting did nothing) it would be fine until I was copying files to it again. Today, it did this multiple times, and then Airport Utility popped up saying the "internal disk needs repairs". I've read other people who had this problem, but the only thing I can find is that they had to erase it and then it was fine. I have the music library backed up on CDs from a few months ago, but I would really prefer to have the complete one as it stands now. Is there any way for me to fix this problem without erasing the entire hard-drive? I want those files!

Welcome to the discussions!
Open your Hard Drive and look for your Time Capsule on the left under the SHARED heading.
Click the TC icon and a TC folder will display to the right.
Double click this folder to display the xxxx.sparsebundle files that contain all of your backups.
Double click on the xxxx.sparsebundle file for your computer. If a window pops up with a "skip" option, click "skip". A white disk image of your backups will appear on your desktop in a few minutes.
Open Hard Drive > Applications > Utilities > Disk Utility
Select your backup image in Disk Utility and click Verify
Depending on how large your backup is, it may take hours for Disk Utility to check your disk
If Disk Utility reports errors, click Repair to see if that will fix the issues.

Verify/Repair permissions greyed on External discs

Hi
Since I updated to Mountain Lion, the option to verify or repair permissions are greyed in the 2 external discs. Only the option verify disc is available to use.
When I pass the cursor over the unavailable buttons, a message shows :
Check if it were set the right permissions to all files and folders installed by apple.
Not available because selected disk is set to ignore ownership
One of the disc only have videos and I checked info. And there was a check in ignore ownership. I already unchecked, but it remains unavailable to verify/repair permissions.
The other is time machine and it has not that option.
I already formatted the external disc from OSX and created a fresh partition.
The problem persists

Repairing permissions on a Snow Leopard disk while booted into Mountain Lion would likely screw up the Snow Leopard permissions. Only the booted system knows what the permissions should be for itself.
What do you mean by that ? I made a clean install of Snow Leopard and then upgrade to Mountain Lion.
I made the verify permissions before the upgrate and after the upgrade. In snow leopard there was a lot of permissions to repair and even after repaired, they still remain there when I made a 2º check.
Then I upgrade to Mountain Lion and made a verify permissions and only one permission appeared to repair (...javaappletplguin.plugin). Did I do anything wrong ?

Mountain Lion download can't be verified.

I have a late 2008 Aluminum MacBook and was running Leopard. I was told it met the requirements to upgrade to Mountain Lion. I bought the Snow Leopard disk. That installed just fine and I got the software up to 10.6.8. I went to the App Store and purchased Mountain Lion. The first time it downloaded and was installing, it froze. I restarted the computer and it installed fully this time, but at the very end said
"This copy of the Install OS C Mountain Lion application can't be verified. It may have been corrupted or tampered with during downloading. Delete this copy of the application, and go to the Purchases page of the Mac App Store to download a new copy".
I have seen similar questions asked, but they were either really old or were for newer Macs. Can anyone help me figure out how to get it to download and install properly? I already tried to download a new copy like it suggested, but I got the same error message.

Since you are starting from an installation of a retail SL star the MB on the SL disk, holding the C key and then run Disk Utility to repair and verify the hard drive.
If that comes back and fixes problems, try the install again.

G4 450 and protools, somehow ran out of memory to startup. Error code 10. Tried turning off extensions to boot but now just locks up as I tried a HD verify/repair and then moved the folder to the desktop screen. cant get it off now.froze.

Ok, I have a Mac g4, os9. ..450 Processor. I Think I upgraded ram, can't remember. Maybe a 512 card. Added an 80 gig internal HD for music storage. Computer was solely used for protools LE 5. I knew I was kinda close on my memory for running the program after recording things with plug ins etc. It was beginning to get slow at startup. Anyway it's been a couple years since I used it. I got it set up yesterday and it wouldn't launch and kept giving me error code 10. So I replaced the battery and tried again. the small finder icon in middle of screen would then pop up and alternate with a "?". Then it would change to a pict of a hard drive disk and then a me alternating "?". It would still give me the error code if I clicked on anything. So I then held down the shift key to turn off extensions as it had mentionEd to do a couple times. Still would give me the error code on my home page. If I tried to get into my hd which is on desktop it would give me the message, but somehow it did open one occasion and I went into it and scrolled to disk verify and repair. Did it. Said things were fine. I then saved the results in a file which was then offered along with location. I chose desktop. Probably really bad idea in hind sight.. It did it, but now no matter if I turn extensions off, the home screen pops up but then goes blank. The hard drive icon along with the new folder, and my protools icon immediately dissapear. And it freezes. at one point a message did pop up saying finder could not start up because there is not enough memory available. I'm not a computer guy. Ive tried finding the guy who helped me set this thing up 10 years ago but to no avail. If I can be guided to somehow uncover some of the unneeded memory usage I would then learn how to more efficiently use it. How the heck do I even start. I can't get to a screen which shows what's eating my computers space to even start getting rid of unneeded stuff. Please help if you can. I have so much to loose if I can't get it to work. Btw...I no longer have the os9 disk. I think it was tossed 10 years ago or more. May not even have my original pro tools disks anymore. Uggh.

Ouch, tough spot, but offhand I'd say some memory may have gone bad, or maybe just needs re-seating after all this time.
Not much you can do, but try this anyway...
PRAM reset, CMD+Option+p+r...

In fact, do 3 in a row, takes a bit of time.
