Disk repair on iMac

i routinely run the disk repair utility on all my computers. I runs OSX 6.8 on my iMac and when I run verify disk, i get this message "Volume header needs minor repair" and the verification run will not complete the verification. I then run disk repair off the install disk and get message that everything is ok. Have also run repair permissions and no problem shown. Need some suggestions on what to do next. I do not detect any operational issues but want to correct before I run into a problem.

No need really to bother with verification. If the repair using the install disk says everything is OK - it is!

I have a partition on my IMac disk and Windows 7 loaded on one partition. I tried to open and W7 will not open and cannot repair itself. Is there a diagnostic/disk repair from Apple that I can try before reloading W7?

I have a partition on my IMac disk and Windows 7 loaded on one partition. I tried to open and W7 will not open and cannot repair itself. Is there a diagnostic/disk repair from Apple that I can try before reloading W7?

Csound1 What Ive been trying to explain is that I have been running bootcamp, I open the app where the first screen is the introduction, i hit continue, the first time I select "download the latest windows support software fromm Apple" then I return and instead select "Install Windows 7." Then hit continue. The third screen is where I "Create a Partition for Windows" I set Windows to 80 gigs then hit INSTALL. As stated before Bootcamp cannot find the install drivers saying "The installer disc could not be found." My windows software is on a USB drive not a disc, I tried using a virtual disc reader to make it appear that the windows software was running on a disc, still no luck. What I would like to know is how to install windows on bootcamp.

IMac 3.06 dual core beachballing after disk repair

Can't get to the bottom of what's going on with my machine. It's very slow after start or wake-up, beachballs with lots of disk activity even when no apps are open. After twenty minutes or so everything seems OK, well nearly OK as it will still beachball a bit every so often.
I ran the disk repair utility after having the same symtoms a couple of weeks ago and it successfully repaired it.
Running permissions repair doesn't flag up anything unusual - core tasks and java which Apple indicate is normal. These show as repaired but if you run the repair again the same result appear.
Running the activity monitor doesn't seem to show any unusual activity. kernal_task consumes most of the real memory (around 300mb), mds uses the most virtual memory (400mb).
Any help very much appreciated as this driving me nuts.

Need disk repair help fast!

My internal CD drive broke so I bought an external one. Problem is that the computer is in need of serious Norton repair and when using the Sony external CD/DVD drive to run the Norton disk the computer does not recognize the hard drive so I can't repair anything. In other words, I put in the Norton cd and it shows up just fine on the desktop but when Norton opens up and I am supposed to choose a disk to repair nothing shows up to choose from. Nothing at all, just a big blank space. The external drive works because I've burned from it although when I try to burn directly from, say iTunes, it goes to the origional disk drive which is broken so I have to use the toast light program to burn. Maybe there is someway I can make my external drive the default one? It is taking forever to load each program and I'm feeling doom with the way the computer has been acting lately and I really can't afford to be without it as I run my business from it. thanks

Hi again, Donna,
Happy to hear you got rid of Norton!
You say your Mac has not panicked since you got rid of Norton, right? If so, you may have already fixed the kernel panic problem. I have not had a single kernel panic since I uninstalled Norton years ago.
If you do experience another kernel panic, the advice about kernel panics that you got from mrtotes is about the best that most Mac users can do for themselves. As explained in those suggestions, kernel panics are often hardware related. Be sure to disconnect all external devices that are not absolutely necessary when checking for and attempting to solve kernel panics.
You should not need to take your Mac to an Apple Service Technician for kernel panics if you can fix it yourself with the advice you have already been given.
<hr width="85%">
Next issue: You mention that your Mac runs slow (the beach ball spins for a long time.)
If you multiple applications running, close all but one and see if the problem goes away. If so, you may just be working your Mac too hard. Run fewer apps at a time.
If you have any external devices, including your external CD/DVD drive, connected, unhook them all and check to see if the beach ball goes away. If so, one or more of your devices may be the source of the problem. You can find which by reconnecting only one at a time and then checking to find whether the beach ball comes back. If no one device causes the beach-ball to reappear, try connecting two at once to see if any of your external devices might be conflicting with each other.
Your Mac may need basic Mac OS X maintenance. You have already done a Safe Boot, (and perhaps a disk repair), so try a permissions repair next.
Unless you have set the slider for your computer to "Never" sleep in System Preferences > Energy Saver > Sleep, you should also force background maintenance tasks as explained in
http://docs.info.apple.com/article.html?artnum=107388
The article lists several equally effective ways you can do this, I personally use MacJanitor, which is free and very simple to use.
FileVault slows disk operation and adds processor tasks to your Mac. If you have enabled FileVault, turn it off (turning FileVault off can take a while) to see if your beach-ball problem goes away.
One other thing that can cause slow (beach-ball) operation is that your startup disk may be too full. Check free (Available) space with Finder > File > Get Info. If you do not have at least 10 GB of free space, try Increasing available space on your hard disk.
For more comprehensive suggestions on OS X Maintenance, see Gulliver's

Disk repair utility & printer issue

I will admit right now that until last night, have never touched an iMac but I have a friend that due to health issues, needs a hand. Can I ask a couple of questions of this forum?
1: She has an external Lacie H/D that is making wierd noises after being knocked over. Her backup software says to run the Disk Repair Utility. I haven't the slightest idea where to find this Disk Repair Utility, nor if I can run it on an external drive.
2: Her printer, mac book and iMac were recently moved from one location to another home. I need her printer connected wirelessly to both computers. I was able to get her Macbook connected but I am having issues with iMac. Can I uninstall her printer and reinstall? Not even sure how to do that basic process so advice would be appreciated.

Disk Utility should be able to check the LaCie - whether it will be able to complete any repairs that may be needed will become obvious when it's attempted. Disk Utility is normally in the Utilities folder within the Applications folder.
Regarding the printer, yes you can uninstall it in System Preferences>Printers & Scanners (or similar wording depending on version of OS X). The +/- buttons add/remove printers.
If you still have problems, post back.

I never received an installation disk with my iMac. I do require one now. How do I get it?

Hello everyone,
My wife and I purchased an iMac about 1,5 years ago. Perhaps 2. And everything worked perfectly. We even got the iPad 3 to go with and next month an iphone 5.
However, since a few weeks my mail didn't respond anymore. Did not open, didn't do anything anymore. I found a solution and had it working again.
NOW, it's jPhoto that is not responding anymore. Though only on MY account. We have two accounts on the system, but with my wife it is working. Just not on mine.
I have found Disk Utilities and did a permissions repair. Which worked. I think... But then the disk repair does not. I can verify the disk but not repair it. It requires a reboot from the Mac OS X installation disk.
I never received one. Was I supposed to get one with my iMac? Or should I make one? Can I still make one with the problems I am having? Or am I copying the problems to that disk?
Can anyone enlighten me?
Thanks,
The Demacker Family.
PS: We did update to iOS 10.6 a while ago.

In the meantime, if you really are on 10.6, you can try and repair the drive by using these options, both explained here. Safe Boot and fsck from single user mode.

After getting the dreaded gray/blue screen, I tried to run disk repair on the internal disk. I got an error message saying "Disk Utility can't repair this disk and restore your backed-up files. The volume Macintosh HD could not be verified completely

After getting the dreaded gray/blue screen, I tried to run disk repair on the internal disk. I got an error message saying "Disk Utility can't repair this disk and restore your backed-up files. The volume Macintosh HD could not be verified completely." What do I do now? This is an iMac and I'm running 10.6.8.

Clean Install of Snow Leopard
Be sure to make a backup first because the following procedure will erase
the drive and everything on it. See below for how to clone a drive.
     1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
         with your computer. Insert the disc into the optical drive and restart the computer.
         After the chime press and hold down the "C" key. Release the key when you see
         a small spinning gear appear below the dark gray Apple logo.
     2. 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 the hard drive entry from the left side list (mfgr.'s ID and drive
         size.) Click on the Partition tab in the DU main window. Set the number of
         partitions to one (1) from the Partitions drop down menu, click on Options button
         and select GUID, click on OK, then set the format type to MacOS Extended
         (Journaled, if supported), then click on the Apply button.
     3. When the formatting has completed quit DU and return to the installer. Proceed
         with the OS X installation and follow the directions included with the installer.
     4. When the installation has completed your computer will Restart into the Setup
         Assistant. Be sure you configure your initial admin account with the exact same
         username and password that you used on your old drive. After you finish Setup
         Assistant will complete the installation after which you will be running a fresh
         install of OS X. You can now begin the update process by opening Software
         Update and installing all recommended updates to bring your installation current.
Download and install Mac OS X 10.6.8 Update Combo v1.1.
You may be able to backup your data if you have an erased external drive you can use. Before you do the above but after you have opened Disk Utility you can try to clone your drive:
Clone using Restore Option of Disk Utility
1. Open Disk Utility.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Select the destination volume from the left side list and drag
       it to the Destination entry field.
5. Select the source volume from the left side list and drag it to
      the Source entry field.
6. Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal startup drive.
Now this will only work if the drive is accessible and can be cloned by Disk Utility. Otherwise, you would need to access your drive from another Mac that you can connect via Firewire - Target Disk Mode.

Recovery HD disk repair failed

Thanks

Disk repair what do I do?

Ok my iMac is not even a week old and I'm seeing this...
What do I do?!
I hear your supposed to put the Mac OS X Install disk and hold "C" on a restart
but what happens when I do that I don't want any data to be deleted
and I don't have a back-up drive yet to back things up if something goes wrong. Will a disk repair erase data?

Hi
AFAIK, Disk Repair does not erase data so it should be safe to do it. When you restart from the install disk, choose the language & go to the next screen. A menu bar will appear, choose Utilities>Disk Utility. Select your disk (not the indented partition name (think that's right)) & click Repair Disk. Repeat this until no errors. If this doesn't fix it then you may need 1 of these 2 programs

It it always a good idea to have a backup, there are many posts regarding cloning/backing up your HD.

Disk Repair Failure

I have an imac G4 15" Flat Panel 800 MGhz and I have been told that my hard drive went bad so i am about to install a new one. I probably should anyway, the upgrade will be nice. I hope. Anyway, I am trying to learn all I can from this experience so I have another question.
I was getting a grey screen with a folder icon with a flashing question mark on it so I did a disk repair and got this error message "Disk Utility stopped repairing "Untitled 1" because the following error was encountered: The underlying task reported failure on exit.
I then restarted the computer with my OSX Install Disk inserted and held down the shift key and the screen had the following on it:

After this happened I connected a imac G3 to my imac G4 with a Fire Wire Cable hoping to target my files and recover them. Then this message came up:
Inserted a disk containing no volumes that OSX can read.
So what does this mean?
If my Hard Drive is ruined can I recover my files?
I know there are some geniuses out there so I will await your reply.
Thank you

First, check your SMART status of the drive with Disk Utility. If SMART is not verified, you should get another drive before you start loosing data.
When I got similar disk and 'underlying task' errors, I re-formatted the drive and that removed the errors.
I backed up my data to an external firewire drive of the same capacity by booting my PB off my Tiger install CD (the 10.3 should work too) with the firewire drive attached.
Select Disk Utility from one of the menus after you booted off the CD. In Disk Utility, select the Restore tab. Drag your internal PB drive into the source field, and drag your FW drive as the dest field. You will want to erase the destination. Just be careful to get the source and dest disks straight! Click restore and your PB HD will be copied over to your external. You might want to boot from your external to make sure it comes up and looks like it would from the internal drive.
Once this is complete, use Disk Utility to erase your internal drive. Verify your disk to make sure all the problems are gone.
Then run Restore again, this time using your external drive as the source, and the internal as the destination. When restore is complete, your PB will be bootable with all your stuff. Plus, you just made a full backup on your external drive!

Can not open any files following Disk Repair! Help!!

Hi. My iMac has failed to boot up a couple of times recently. I have used the Disk Repair utility to solve it twice. Both times it found errors and repaired them but the second time when I boot up normally again I can not open 99% of my files, from spreadsheets to videos. I can see the files in finder but if I click on them nothing happens. Also Finder behaves strangely jumping back to higher folder levels by itself. I can use my yahoo mail account to attach files to an email, send them to another machine, download them and they are fine so it seems like they are still there but my imac can't understand what they are in order to open them. Any ideas? - I have about 900 gig of files that i'd rather not email on by one to get them back!!! Thanks. Alex

You should not be running without a backup, preferably a bootable clone on an external hard drive. Some have redundant backups, one a clone, the other Time Machine, on two different external drives. I have clones on two externals. Drives can fail without notice at any time and everything goes down the drain.
You can use free/donationware Carbon Copy Cloner.

Disk Repair help

Hi I am getting a message in disk repair that says "This drive has a hardware problem that can't be repaired. Back up as much as possible and replace disk.
See an Apple Dealer.
It is Media S.M.A.R.T status failing (whatever that means)
Does this mean my hard drive is fried?
Thanks all help much appreciated.

Hi WZZZ
I went out and bought a new iMac. Time Capsule had worked perfectly, so all is wonderful again. I had tried to
back up with another external hard drive before the crash, but it didn't work, so I am glad the TC did it's job.
I am going to get a new hard drive put in the old iMac (it's 6.5 years old). I just upgraded the OS to Snow Leopard
from Tiger, and increased the memory, so if it works for a while as the grandkids computer I will be happy.
I just wanted to thank you for your quick answer. It really helped me to make some decisions.

New hard disk on old imac - best way to transfer back-up from Time Machine??

Hello,
The hard disk on my 2008 iMac died and I just got my computer back from the repair guy, who installed a new hard disk (and the latest Yosemite).
Which is the best (and most fail-proof) way for me to transfer all the stuff from the old hard disk - which is on my Time Machine – to the new one?
Before getting repaired, my iMac was running on Mavericks. My Internet access has also changed (it broke down the same week… ). Don't know it that makes a difference.

Connect your backup drive to the computer. Because you had Mavericks installed before you can only restore your Home folder from the backup. Use Migration Assistant in the Utilities folder to transfer your Home folder, third-party applications and support files, and system preferences. Upon completion you will have two user accounts. The one you are now using and the migrated one. Log out of the account you are using then log into the migrated account. Open Users & Groups preferences, click on the lock icon and enter your admin password for the migrated account. Select the account you were using and click on the Delete [-] button. Select the option to delete immediately.

Disk Repairs Please Help!

I know there are many posts about this problem, but none of them have seemed to help me out. My Imac runs fast and fine, but when i pull up safari pages take unusually long to load and sometimes dont completely load without saying something like "23 out of 25 files downloaded, or 4 problems while downloading page." I figured maybe i need to do some disk repairs. While trying to verify my disks i get the warning "This disk needs to be repaired, start up comp with another disk annd then use disk utility to repair disk." The problem here is that i don't have my installation disk and this is where i am stuck! Now this might not be my problem anyways, so maybe someone could help me out.. The problems with the disk are "Invalid directory item count" & "The volume Macintosh HD was found corrupt and needs to be repaired."
I would really really appreciate it!

First, you cannot repair the drive without the installer disc or another bootable system such as a bootable clone on an external drive. So you can contact AppleCare to purchase replacement discs. Meanwhile, you can purchase Disk Warrior that will come on a bootable DVD.
You can try some intermediate efforts to repair the drive by doing the following:
Boot into single-user mode. After startup is completed you will be in command line mode and should see a prompt with a cursor positioned after it. At the prompt enter the following then press RETURN:
/sbin/mount -uw /
/sbin/fsck -fy
If you receive a message that says "***** FILE SYSTEM WAS MODIFIED *****" then re-run the command until you receive a message that says "** The volume (name_of_volume) appears to be OK." If you re-run the command more than seven times and do not get the OK message, then the drive cannot be repaired this way. If you were successful then enter:
reboot
and press RETURN to restart the computer.

How do I carry out disk repair or safe boot...

...if my imac freezes at grey screen and won't recognize any keyboard? It does recognize the wireless mouse.
The computer started freezing at the grey screen last week. I tried disk repair, no good. I tried system restore, no good. It still stops at the grey but I can't try resetting PRAM or booting in single user mode or anything because it won't recognize either a wireless or a usb keyboard.
Ist kaput?

Not a lot you can do if the keyboard is not recognised. I suppose if you had another Mac you could connect them via FireWire or Thunderbolt and try to repair using Target Disk Mode.
