Mac OS X 10.6.5 Disk verification problems

Hi, I just used the disk repair utility and oh boy i found a problem. Here is what it says:
Performing live verification.
Checking Journaled HFS Plus volume.
Checking extents overflow file.
Checking catalog file.
*Incorrect block count for file live.4.indexPostings*
*(It should be 4096 instead of 2048)*
Checking multi-linked files.
Checking catalog hierarchy.
Checking extended attributes file.
Checking volume bitmap.
Checking volume information.
+**The volume Macintosh HD was found corrupt and needs to be repaired.**+
_Error: This disk needs to be repaired. Start up your computer with another disk (such as your Mac OS X installation disc), and then use Disk Utility to repair this disk._
I have read about people having to restore and back up their computer. Do you think that that will be required and is this major or minor? Thanks

You should always have backups, and to backup any files you need even before running any repairs. Disk Utility RESTORE can be one way to copy to another hard drive.
Could even be a bad sector on the drive causing trouble.
I would treat any such error as worst (and hope for the best), but I would not be without backups and stronger 3rd party utility.

CopyCatX is another volume copy program.
And before you do anything, consider installing OS X to another hard drive, and setup a 2nd partition for your backup/clone or recovery.

Disk Verification Problem...?

Hello Folks,
I'm hoping this is the correct section to post this......
I've been posting over on the iDVD section of this site where 'Glo H' was trying to help me solve a problem I'm having. We seem to have run our course there and he suggested I post here as we've moved out of his sphere of expertise.
Just some background to the problem:
Up until a couple of weeks ago I was happily burning .avi movie files to DVD using iDVD.
One day the audio on a resulting DVD lost the audio at around eight minutes into the movie. I checked the original .avi - it was fine. I tried burning other .avi files which I'm made DVDs from previously ( and they worked fine ) and also tried changing the brand of disk several times, playing them on different computers, DVD players etc. The audio stopped working on all of them at around 8 to 10 minutes into the movie.
I was advised by 'Glo H' to make a disk image of an .avi and check this. I did so and the audio cuts out at the same point. He then suggested I erase my iDVD preference file, then re-open iDVD to create a new one. This I did.
The next suggestion was to open disk utility and run 'Verify Disk Permissions'. When I did so I got this message after a short time:
"First Aid Failed. Disk Utility stopped Verfying Macintosh HD - following error encountered - Filesystem repair or verify failed".
I went ahead and ran the 'Repair Disk Transmissions' and got a 'Permissions Repair Complete' message back.
I'm just unsure of where this leaves me with my hard disk and the problem with which running 'Verify' seems to be showing.
I haven't tried burning a DVD with iDVD yet and will wait until the above problem is ( hopefully) solved..
Any help will be most gratefully received.
Many thanks,
Michael.

Michael,
Unfortunately, you have had a disk error. You should first attempt to repair your file system:
1) Boot to your Leopard install disk (or the "Software Restore" disk #1 that came with your Macbook). Insert the disk, then start or restart and hold the "C" key. When the installer loads, select a language, then open Disk Utility from the "Utilities" menu.
2) Select your internal drive in the list at the left side of the Disk Utility window. In the "First Aid" pane, click the "Repair Disk" button (not the "Repair Disk Permissions" button). Let us know what errors are reported and/or what repairs are made.
3) Quit Disk Utility to return to the installer, and quit the installer to restart normally.
Disk Utility may or may not be able to effectively repair your disk directory. Even if repairs are made successfully, this will fix your file system but it will not repair files that may have been damaged by the disk error. In the end, you'll need to backup all of your data, then format (erase) your internal drive and reinstall OS X.
If you have a Time Machine backup, you can restore your entire installation of OS X, but you must use a backup that was made prior to the occurrence of the disk error (prior to the start of your current problems). A better solution might be to reinstall OS X normally, from the DVD, then restore just your user data from the backup. If you do this, the easiest option would probably be to use the Migration Assistant to restore your user data from the Time Machine backup.

Disk verification stopped by user

My aunt has a G5 iMac with OS 10.4.11. A year ago, her password mysteriously changed, and when she tried to verify the disk using DU, before the verification finished it would say "stopped by user."
We reset the password with Single User Mode, and she could again verify her disk.
Now, suddenly she can't connect with the internet. Her DSL modem says it has sync and has Ethernet communication with the computer, but if she clicks Network in Profiler, it doesn't list Ethernet or Firewire or anything else.
If the modem says it has Ethernet communication, I suppose the iMac's Ethernet hardware works. What problem could interrupt disk verification and make the OS unaware of Ethernet and Firewire?

Two thing to try:PRAM reset and an SMU reset.
Also, using Disk Utility to check the disk:
1. Start from your Mac OS X Install disc: Insert the installation disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk.

Hard Disk verification.

recently i ran a verification (occasional system checkup) and my main hard drive could not be verified. so i used the osx install disk to repair my mac os system disk. and it worked! however i noticed that im having to do this more often. and every time im having to repair form osx install disk. the disk is repairing ok. over all i never had any problems in performance, or anything its just my disk wont verify, im worried that something will go wrong. its just i never had to do this before, but now it came up once twice and more frequently + randomly. so is my disk failing (slowly) ?
side notes:
all 4 bays are occupied, no verification problems in other drives.
i have windows 7 form few games i play - shouldnt affect osx
im just worried, its coming up more and more.
would apple replace drive under warranty?
please let me know, thank you

Not without a backup first!
Do you have a hard drive for backup with Time Machine activated? If not, STOP!
Get an external hard drive that is at least 20% larger than your boot drive, or even better 20% larger than all of your active hard drives on your system (excluding any Windows Boot camp partitions) and activate Time Machine and let it back up your system.
Do that FIRST!
Once you have a backup, then you can start experimenting with tech tool pro. The volume rebuild rebuilds the directory on your hard drive. The directory is a low level part of the file system on your hard drive. Think of it as a table of contents and index - it lets the computer know where to find your files on the hard drive. It's a potentially risky operation, and if there is a physical problem with your hard drive (which it is beginning to sound like there might be) and a problem writing out the directory back to your hard drive fails and you loose the volume, you will at least have a backup.
Some will insist you need to make a backup with a program like SuperDuper! That's fine if you want to, but there is nothing wrong with TimeMachine. The reason I encourage TimeMachine over SuperDuper or other cloning as a backup is TimeMachine is automatic and built into the OS. You are much more likely to backup your machine if it's easy to do, and there is no backup procedure easier than TimeMachine. And you can restore from a TimeMachine backup, you just can't boot from it. But you do have your Snow Leopard DVD which you can boot from, and you can restore from TimeMachine as you re-install the OS once booted from your install DVD.
Back up your data first, then you can start troubleshooting your hard drive.
You might want to download this utility that will show you the SMART status of your hard drive:
http://www.apple.com/downloads/macosx/systemdiskutilities/smartutility.html
unlike Disk Utility, this program will show you all the stats of your SMART diagnostics, not just a summary like the Disk Utility. I just tested it out on my MacBook Pro and discovered my hard drive is failing (!!) so off to the Apple store I will go tomorrow to get it replaced! I had heard a few "clunks" from the hard drive and just assumed it was from the sudden motion sensor - apparently not. I'll be buying a family license of that utility and also installing it on my Mac Pro and PowerBook!
BTW - it is perfectly normal to have SMART errors and bad spots on a hard drive and programs like Tech Tool or Disk Utility not report any issues - that's because SMART works at a lower level within the hard drive. Hard drives are designed to self-correct a certain amount of errors, and it's designed to be transparent to the operating system or higher level programs. A few errors are OK, it's when you start seeing an excessive amount of errors (as I am on my MacBookPro hard drive!) that you should start to be concerned.

How do I use a Mac Mini + Airport Express + Time Machine disk to backup another iMac

How do I use a Mac Mini + Airport Express + Time Machine disk to backup another iMac?
The question pretty much says it all.
I have a Mac Mini with an attached 3TB Hard Drive used for Time Machine Backups.
I have an Airport Extreme base station which services that machine plus several others.
I would like to backup my new iMac and a MacBook Pro to the Mac Mini.
What do I need to do on the mini to export that hard drive so that it can be used as a Time Machine target from the other systems?
All systems are running 10.6.8.

Well you would have to do backups over a network which is much slower and has highest chance of becoming corrupt. I think your best option would be to get an apple time capsule to act as a network and back if thats how you wanna do that

I have Adobe Photoshop Elements 10 and Adobe Premier 10 loaded on a Dell PC. Do I need to uninstall from the Dell before I install on a recently purchased Apple Mac Pro? There are separate disks for Mac and PC in the package.

Generally, it's ok to install on two machines as long as they are both yours and you only use one version at a time.
BTW, this is the forum for Adobe Contribute.

My Mac is telling me that my disk is full. I have bought an external hard drive and have just listened to a youtube tutorial on how to move iTunes library to the external hard drive. If I do this can I still load new media on my Mac without the external?

my Mac is telling me that my disk is full. I have bought an external hard drive and watched a youtube tutorial on moving iTunes library to external hard drive. Will I still be able to use iTunes on my Mac for new media or will this now only work through my external hard drive?

To do this you need to learn the details of how iTunes works. For example, you just said, "leave my iTunes on my computer". iTunes is the application itself so of course it has to be on your computer. That said, I therefore don't know what you mean when you say leave iTunes on your computer. The phrasing of your question suggests to me, if I may be frank, you don't understand how iTunes works fully and we can't just give you a "do this" answer and have it work out. It would be too easy to make a mess of things.
What are the iTunes library files? - http://support.apple.com/kb/HT1660

What are all those iTunes files? - http://www.macworld.com/article/139974/2009/04/itunes_files.html
Where are my iTunes files located? - http://support.apple.com/kb/ht1391
Yes, you can download media and delete it again (but if it is from the iTunes Store there is the possibility you can't always download it again). Of course if you want to keep a copy you can archive it. I have done that with some files for which I have no room on my computer. I transfer them to an external hard drive and delete the reference to the file (but not the file itself) from my library. If I want a quick listen I go to the file on the drive and use Quicktime player or something else non-iTunes so I don't have to have it added to iTunes and delete again. I don't know if that is the solution you are looking for. I could leave the reference in iTunes but if the file can't be located by iTunes it will tell me there is a broken link = ! I guess I could live with that except I periodically scan my library for broken links and don't want it getting confused with ones I have done deliberately and ones suggesting I am really missing a file somewhere.
Another possibility is to make a second iTunes library for material you are archiving and only use that library when the computer is using the external drive. There are tricky aspects to dong that but it is a possibility too.
The simple solution for most people with computers with tiny drives (as most seem to be these days) is to put their whole iTunes library on an external drive and use it from there.

Hi, my mac air is really low on disk space, can I remove itunes (which is huge) to an external hard drive to free up space?...and then run it from the hard drive instead of the mac,even if the mac no longer has space to accomodate the size of the library?

Yes.
Copy your music iTunes Library folder to the external drive and change the Advanced settings in iTunes to point to this new location.
Once you're happy with these changes you can delete the same Library from your User account to free up space on the internal drive.

It is standard Mountain Lion error due to the networking ability which is comparable to wet string. (actually that was lion.. it dried out some with Mountain Lion.. higher in the hills perhaps!!)

It sounds like your hard drive either has a software problem that Disk Utility cannot fix or that the HD has failed (mechanically).
Your Mac may have booted either to your recovery partition or to internet recovery in an attempt to repair the drive- I can't tell from your post.
I'll assume that it was the recovery partition.
Try to boot into internet recovery (hold down option command R at restart), and see if you can repair your HD with Disk Utility. You should also repair permissions while you're there.
If that doesn't work, try to boot into single user mode (restart, hold down ⌘S until you see a black screen with white text) and repair your hard drive. Here's a reference with directions: Repair Your Hard Disk in Single User Mode | Everything Macintosh
If that doesn't work you have a few options:
If your mac originally came with installation disks, you can try to boot from the installation disk and then see if you can repair the HD.
There is a small chance that Techtool Pro 7 will be able to repair your HD if Disk Utility can't.
If none of that works then your HD has probably failed and will need to be replaced, which is not too difficult to do yourself if you can use a screwdriver.

Erase 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.

My Mac Mini will not read TDK disks from my iMac G3.

My Mac Mini will not read TDK disks from my iMac G3.
I used an iMac G3 (2001) -- the ones that looked like a big pod -- running on OS X and saved files to TDK CD-R, 700 MB disks, which worked fine. Now that I have a Mac Mini (model number A1347) I cannot get this computer to read those disks, made on the iMac G3. Once inserted each disk will open and I can retrieve files for a short period, then the problems start. The computer makes some noises, the beach-ball/pinwheel goes around and I cannot get the files to open or the disk to eject. After a while the disk does eject -- to my relief. I keep using Control+E until ejection happens.
My Mac Mini (2010-2011) is hooked up to a View Sonic HDMI LED monitor, an iOmega external hard-drive for backing up, an Epson Stylus C88 Plus printer and to the internet by a fibre 10MB feed. The Mac Mini runs on OS X version 10.6.8 Snow Leopard: Processor Speed:2.66 GHz
I took the Mac Mini to an Apple retailer and he hooked the computer up to one of his monitors and it read the TDK disks just fine. I am now using Sony CD-RW, 700 MB disks, but I would prefer to use my TDKs because I have such a large pile of blank ones to use and there are those TDK disks with information that I want to look at from time to time. Can anyone tell me what to do?
DJG

Try disconnecting everything attached to the Mini except the monitor.
If that doesn't work, try setting up another admin user account to see if the same problem continues. If Back-to-My Mac is selected in System Preferences, the Guest account will not work. The intent is to see if it is specific to one account or a system wide problem. This account can be deleted later. If successful, copy the files to the original account Public/Dropbox.
Isolating an issue by using another user account
If the problem is still there, try booting into the Safe Mode using your normal account. Disconnect all peripherals except those needed for the test. Shut down the computer and then power it back up after waiting 10 seconds. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. When you reboot normally, the initial reboot may be slower than normal. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application un-installer. For each disable/delete, you will need to restart if you don't do them all at once.

TS2570 Question re: "Start from your Mac OS X Install disc; use Disk Utility"

I've worked my way through the step-by-step trouble shooting in the TS2570 article up to "Start from your Mac OS X Install disc; use Disk Utility". So far, every step results in the same outcome - my formerly trusty 2007 Intel duo core iMac (24") will not start up, freezing on a grey screen with a blinking question mark on a folder. I don't completely understand this next step. I have both a Leopard and a Snow Leopard disc. I'm not positive whether these were for the iMac, or my old Macbook Pro. I assume this makes a difference.

Question (?) Mark, Blinking Folder, or Gray Screen at Startup
These are related but not identical issues. Their causes are outlined in Intel-based Mac- Startup sequence and error codes, symbols. Solutions may be found in:
A flashing question mark appears when you start your Mac
A flashing question mark or globe appears when you start your Mac
Mac OS X- Gray screen appears during startup
In most cases the problems may be caused by one or more of these:
a. Problem with the computer's PRAM - See Resetting your Mac's PRAM and NVRAM.
b. Boot drive's directory has been corrupted - Repair with Disk Utility.
c. Critical system files are damaged or deleted - Reinstall OS X.
d. The disk drive is physically non-functional - Replace the hard drive.
Note that the information I have provided is what Apple recommends, If other users suggest different solutions than found here, then be sure what they recommend does not impact on your warranty, if any, or ability to get continuing Apple service.
Please don't start removing drives or changing cables unless you know what you are doing and have exhausted other non-invasive alternatives outlined here. If you perform any work yourself that is unapproved by Apple, then you will void any warranty you may have and lose all further Apple Support.
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.
The main difference if you are using Lion or Mountain Lion is that you must first boot from the Recovery HD. Simply boot from the Recovery HD to perform the above.
Reinstall Snow Leopard Without Erasing The drive
1. 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.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install Mac OS X 10.6.8 Update Combo v1.1.
Reinstalling Lion/Mountain Lion Without Erasing The 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.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. 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 main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

Hi Janice,
What version of Mac OS are you using?
Adobe does not recommend migrating the software from one disk to the other.
Please run the setup file for Acrobat and reinstall the software. You might want to delete the existing version of Acrobat installed before reinstalling it.
