how do I run a disk repair?

I have some friends in Vancouver originally from White Horse. Small world.
What is the context in which you need to run disk repair? Are you using Lion or Snow Leopard?

Im having trouble getting my macbook pro to boot up after a fail safe boot, im getting as far as the grey screen with the apple loggo. so im trying to run a disk repair but is saying the disk is locked, how do i unlock disk??

Some clarification may help.
You say you cannot boot normally. It shows a gray screen with the Apple logo.
Did you say it will boot successfully in Safe Mode (boot, then hold down the Shift key)?
How did you boot the machine to run Disk Utility? (Which keyboard combinations)?

How do i run the disk utility to repair permissions:confused;

how do i run the disk utility to repair permissions
i think i hav the same problem as you all iv been
restarting and deleting and renstaling but nothing seems to work
the only thing i havent don is this repair prmission
thing can someone type some instuctions on how or lead me where to
go

are you using mac OS10.2 or later?
if so, this is what I did to solve this most frustrating
problem. Go to Applications/Utilities/Disk Utilities
In the Disk Utility window, click on your hard drive, make
sure you're in the First Aid tab, then click on Repair Disk
Permissions.
Once the permissions were repaired, I took the advice of
another user here on the forum and reinstalled Flash Player 6, as
it was the one that was working before I tried to upgrade and it
screwed everything up.
Hope this helps

I recently purchased an HP officejet 6600 and whenever I put in the disk to install the printer nothing pops up. How do I run the disk on my 2011 MacBook Pro?

I recently purchased an HP Officejet 6600 and whenever I put the disk in to install the software nothing happens. How can I run the program to install it and get started using my printer???

You should be able to go to HP Web site and download the installer. It sounds like you got a bad CD.

HT201250 My external hard drive suddenly says "read-only" should I run a disk repair on it and what does that do?

Has any one used Disk Repair on an external hard drive? Does it erase everything?

Repair the Hard Drive
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, 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.
Fix Permissions for a Locked Drive
Open Terminal in the Utilities folder. Paste the following at the prompt. Press RETURN after each. The first command will prompt for you to enter your admin password. It will not be echoed to the screen. After entering your password press RETURN again.
sudo chflags 0 /volumes/*
sudo chmod a+rx /volumes/*
killall finder
An alternative is to download BatChmod and use it to fix the permissions.

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.

How do I run Win7 Startup Repair from USB to repair Bootcamp installation?

I messed up my bootcamp partition after resizing the OSX partition to give it more space so I found this fix - http://mourougan.com/2013/06/22/repairing-boot-camp-after-creating-new-partition /
The fix worked in that the windows partition now shows up on startup manager but when I try to load it the 'missing operating system' error message shows.
So I need to run Startup Repair from USB but when I try that from startup manager it just gives a black screen and blinking cursor, nothing happens from there...
Can anyone help with getting startup repair to load? any advice greatly appreciated.
Many Thanks

Ok here are the outputs from my testdisk -
Should I go ahead and do the Gdisk part described in that thread using my values from the first screen shot? -
Rebuild GPT4 using start/end offsets
Sudo gdisk /dev/rdisk0
P (print the full list of parts)
D (delete)
4 (part 4)
N (new part)
4   (part 4)
743868416 - Start offset in bytes (start point for Bootcamp part)
+232904697 (Size offset as opposed to End offset)
0700     (Windows part type)
P           (print list of all parts just to see what changes will be made)
W         (Write the new GPT)
Y           (Yes! really write the new GPT)
This will delete and re-write the GPT partition info for /dev/disk0s4.

How do i run a Repair Disk from ARD

how do i run a Repair Disk from ARD

have you considered a netboot image and or a safeboot?
With a netboot image you could try repairing the drive remotely. (the down side is this requires a mac os x server to do)
A SafeBoot can be remotely triggered, and it include automatic disk check and repair. (the downside is depending on how the computer is connected to the network, it may not re-connect to the network when safeboot complete and boots into 'safe mode'. ) I find if the computer is connected to the network by a built-in ethernet adapter, I can usually still access the computer in safe mode
Before running a disk repair or permissions repair, it's a good idea to make sure the computer is backed up.
Also, in the case that a NetBoot, Disk Repair, or SafeBoot fails, you would probable want to be able to physically walk over to the computer.
Resolve startup issues and perform disk maintenance with Disk Utility and fsck explains that SafeBoot includes Automatic Verify and Repair of Disk.
Mac OS X: Starting up in Safe Mode explains how to use the terminal to configure a computer to SafeBoot into SafeMode. It also explains how to turn off SafeBoot after booting into SafeMode.
cheers!

Running Disk Repair

I periodically run a disk repair, especially the permissions repair, however, when I now run the permissions repair, it runs through the script, repairs the permissions. Then I will run it again and it still has the same permissions errors. Why won't it fix the permissions? Any way to save the repairs?

I periodically run a disk repair, especially the permissions repair
Repairing permissions should only be done to troubleshoot a problem and not as routine maintenance.
Why won't it fix the permissions?
Any message containing ACL, SUID, or the first character in the permissions block being incorrect, such as lrwxr-xr-x as opposed to -rwxr-xr-x won't be repaired in this way. The third case is due to an item being a different type than expected, and usually means that you've installed recent updates from Apple.

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.

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!

Disk Repair Errors

I generally run the Disk Repair Utility when I install new software due to some software not abiding by the rules. When I did this a few days ago I came up with the following errors:
Warning: SUID file "System/Library/CoreServices/Finder.app/Contents/Resources/OwnerGroupTool" has been modified and will not be repaired.
Warning: SUID file "usr/bin/lppasswd" has been modified and will not be repaired.
Group differs on "private/etc/cups", should be 0, group is 26.
Permissions differ on "private/var/spool/cups/cache/rss", should be drwxr-xr-x , they are drwxrwxr-x .
In reading most of the postings regarding this condition, there was some hope that it would be fixed in 10.5.5. This is exactly when the errors occurred for me. As soon as I updated:
2008-09-17 13:39:38 -0400: Installed "Remote Desktop Client Update" (3.2.2)
2008-09-17 13:39:40 -0400: Installed "Digital Camera Raw Compatibility Update" (2.2)
2008-09-17 13:41:05 -0400: Installed "Mac OS X Update" (10.5.5)
The modification date on the Finder.app is 2008-09-17 13:41:05, same as the 10.5.5 update. Coincidence? Not likely.
The Disk Utility blurb that these are expected did not include the Finder.app error.

Bruce --
The only real problem here is that the programmers who designed
the Repair Permisions did not have the good sense to just run the
program, and then, when everything is done, simply report
"Repair Completed," or "Everything is A-OK. Nothing to worry about."

Disk Repair Utility Full Disk Error

Today, my MBP froze, as in it no longer responded to keypresses or moving the mouse, so I held the power button until it powered off. Whenever I try to power it back on, it comes up with the apple logo on a gray screen, and a progress bar briefly appears beneath the apple logo, flashes a few times and dissappears, then the computer turns off.
By running the disk repair utility from the OSX install disk, the OSX partition of my hard drive needs to be repaired. When I try to repair it, it gives me an error saying that the disk is too full to do a repair on (I probably have ~10GB free, so this makes sense), and I need to wipe my disk and reinstall OSX .
I have windows installed via bootcamp and I can still boot into that and see my contents of the OSX partition (e.g. I can play my music, watch movies, open documents all of which are on the OSX partition, I just can't boot to it.).
Although probably unrelated, I've run the diagnostics, and everything came up okay. I've also tried holding shift during boot (trying to get OSX into safe mode) and holding command-option-P-R (clear the PRAM) during boot, neither of which helped.
My current strategy is copy a lot of data off my OSX partition from within my windows partition to an external HDD, in order to free up space on my OSX drive, so that hopefully disk repair can do its job. Does anyone know if this will work, or if not, can anyone recommend an alternate work around?

Backup your files, if possible. Your only recourse is to reformat the drive and reinstall OS X. Do not copy or backup files from Windows. If at all possible boot from another drive like your external HDD by installing OS X on the external drive (unless it is already a bootable drive.) You can then copy your data from the faulty OS X volume before erasing it.
You should never permit your free space to drop so low. One should maintain 10-12 GBs or 10-15% of the volume's total capacity, whichever is greater.
Since this problem will likely recur I suggest you consider just replacing the drive with one that is considerably larger. I would also be sure to arrange to maintain a bootable backup on an external drive in case problems such as this one occur.

Disk repair advice

Hi, my g3 ibook is starting to become a little glitchy and I'd like to run a disk repair programme on it, which is the best to use?
I have never done this on this ibook, though i use cocktail to make sure the disk permissions etc are kept up to date.
I am using OS X 10.3.9
I don't have my installation discs with me, do I need to make a hard drive backup first (I have a lacie pocket drive) or can boot up from the repair cd? the last time I did this was on a powerbook running OS9 and I could just boot up from the repair cd.
thanks
