Hi Pondini,
Page: 9. Duplicating a CD or DVD, item 4...
Based on articles like
How to copy previously-burned DVD-R video discs
and
Creating a disk image
I always selected "DVD/CD Master" as the image format when making images from discs.
Is that not necessary?
Thanks,

  • Is anyone else having problems with Verifying and Repairing Disk permissions?

    Hey folks, every time I try to verify and repair disk permissions lately, this is all I get...
    Verifying permissions for “Macintosh HD”Group differs on “Library/Printers/InstalledPrinters.plist”; should be 80; group is 0.Permissions differ on “Library/Printers/InstalledPrinters.plist”; should be -rw-rw-rw- ; they are -rw-r--r-- .Warning: SUID file “System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAg ent” has been modified and will not be repaired.
    I usually get a long list, then repair it, and it seems to keep things clean.
    I'm having trouble with my address book.
    When I move the mouse down the bottom of the page my dock doesn't come up right away, sometimes it won't - I have to command tab to go to another program.
    So I'm wondering if these are related. Thanks for any help!

    Not specifically Sky & Yahoo, but there seem to be quite a few threads with password problems and Yahoo. Is that what you are experiencing. Long thread here:

  • Safe to verify and repair disk permissions with SSD?

    Is it safe to verify and repair disk permissions with an SSD installed?

    Thanks.
    Its just strange, as soon as I repair all my permissions, if I verify them again straight away, there are some that already need re-repairing

  • Verify & Repair Disk Permissions VS. Verify and Repair Disk

    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.
    Repair Permissions is explained here.
    Verify/Repair Disk is explained here.

  • Unable to verify and repair disk, with my new 10.5

    I'm trying to work out some problems on my older G4 desktop (with lamp bass). I upgraded recently from 10.3 to 10.5 (bought new box with the 10.5 disk). I have 750 dramm.
    I wish to verify and repair the disk. I can't figure out h ow with the new 10.5 disk I have.
    In the past, I would boot up my computers with the 10.3 and 10.4 disks (I've had both) with "C" key down, and then I could use the utility.
    That does not work with this new Leopard disk. Won't boot up with the "C" (or the "option" key for that matter).
    That normal? And how do I repair disk for the install disk?
    thx..
    Jon

    Jon,
    The Leopard disk works (or is supposed to work) just like previous versions of OS X. In other words, booting the G4 while holding down the "C" key should boot the machine to the installer.
    A couple of things might get in the way of this happening, though. First, let's establish that your G4 meets the minimum requirements for Leopard. For a G4, the important item would be at least an 867 MHz processor (if I'm not mistaken). Are we still "go?"
    Also, let's eliminate the "duh!!!" possibility of a third-party or wireless keyboard, which may not be supported by the startup manager.
    If you meet the minimum requirements, and you're using a standard, wired USB keyboard, your PRAM may be causing an issue. This happens, sometimes. To clear this up, first flush out the PRAM by holding down Command-Option-P-R at startup, and continue to hold it until you hear a total of four startup chimes. When you hear the fourth, immediately switch to holding the "C" key (with the Leopard disk inserted, of course).
    If this doesn't get you booted to the installer, there may be something wrong with the installer disk.

  • DISK UTILITY PROBLEMS : unable to verify or repair disk and/or permissions

    hi all...first time poster.
    i have been reading past posts for 3 hours and i am still unable to resolve these issues i am having.
    it all started with a failed attempt to install an update (QB2006_R4Updater.dmg) that i downloaded for a new version of Quickbooks Pro 2006 that i just purchased. the install continuously got hung up on "Searching Macintosh HD" looking for the application.
    i called quickbooks tech support and after about an hour of troubleshooting and 4-5 failed attempts to boot in safe mode...the rep told me it seemed to be a system problem.
    regarding safe mode:
    when i try to boot up in safe mode...immediately after hearing the start up tone i press and hold shift until the gray apple appears then release it. the system continues to boot for about 30-45 seconds and then shuts down.
    regarding disk utility:
    i have tried to verify and repair the disk permissions to no avail...i also booted from the osX 10.4.6 installer disk (i am currently running osX 10.4.7) and tried to verify and repair the disk but on every occassion it gets hung up a little less than half way through - no error message - it will just keep going until i need to reboot the system. i cant even force quite disk utility.
    i have also tried removing the itunes.pkg file as well as moving itunes to the desktop followed by running disk utility...but the same results.
    some other info about this system...
    as well as running all of tigers bundled software...i have installed cs2, microsoft office x, suitcase fusion, windows media player and quickbooks pro 2006.
    not really sure what i need to or should do...just want to get the system so i can continue to keep up with software updates and use the utilities to keep everything working properly.
    thank you in advance for any help you might be able to give me.

    From what you've described there are several possibilities, none very encouraging:
    1. You have a motherboard problem
    2. You have bad RAM
    3. Your hard drive is failing or damaged
    Given what you've described I would recommend trying this:
    Boot into single-user mode by restarting the computer and after the chime press and hold down COMMAND-S keys until the computer starts up to a black screen with white type. When startup has completed you should see a prompt. At the prompt enter the following commands pressing return after each:
    prompt> /sbin/fsck -fy
    If you do not get a return message "Filesystem OK" then repeat the above command until the "Filesystem OK" message appears. If you repeat the command more than seven times without success, then the drive cannot be repaired. To restart OS X enter:
    prompt> reboot
    Download the utility TinkerTool System and use it to clear out all user and system caches, font caches, and log files.
    If none of this works, then you will have to reformat the hard drive as follows:
    1. Boot from your Tiger DVD. After the installer loads select your language and click on the Continue button, then 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. Click on the Partition tab in the DU main window.
    3. Set the number of partitions from the dropdown menu (use 1 partition unless you wish to make more.) Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the volume(s) mount on the Desktop.
    4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
    5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
    6. Click on the Erase button. The format process will take 30 minutes to an hour or more depending upon the drive size.
    Quit DU and return to the installer. Proceed to install OS X. You can upgrade to the most recent version by downloading and installing the Combo Updater for the desired version level.

  • Disk Utility can't Verify Disk Permissions" and "Repair Disk Permissions"

    I tried to run "Verify Disk Permissions" and "Repair Disk Permissions" on an external partition, but they all grayed out! "Verify Disk" and "Repair Disk" were fine! The "Owners Enabled" is "Yes". Why they were grayed out ?!
    Get Info on this volume showed:
    Ownership & Permissions:
    You can "Read & Write"
    Details:
    Owner: admin
    Access: "Read & Write"
    Ignore ownership on this volume: checked or unchecked STILL grayed out!
    Other partitions on the SAME drive are able to do "Very Disk Permissions" and
    "Repair Disk Permissions" (as they are NOT grayed out !) The ONLY difference
    between the one (CAN'T) and the rest partitions is that one (CAN'T) has
    owner by "admin", and the rest partitions (OK to veryify pewrmissions) are owner
    by "system". ANY CLUE ?
    -DC

    The options to verify or repair permissions are only available on a disk with Mac OS X 10.2 or newer installed, and all Mac OS X versions set the owner of the partition containing them to system when installed.

  • Mac OS X 10.5.1 - Disk Permission Verify and Repair Functions Are Broken

    Machine: Mac mini with 1.66 MHz Intel Core Duo,
    OS: Mac OS X Version 10.5.1
    Note: Upgraded to Leopard from version 10.4.10
    When using Disk Utility to attempt to verify or repair the permissions of the internal hard drive volume containing the OS, the progress meter stops moving and the verify or repair operation does not finish. The Console log file reveals the problem:
    Mac OS X Version 10.4.10 (Build 8R2218)
    2007-10-29 17:57:06 -0700

    Can't access "efi-boot-device" NVRAM variable
    Can't access "efi-boot-device" NVRAM variable
    Note that the OS version is incorrectly reported as 10.4.10 in the console log. This was the version that I was using PRIOR to installing Leopard. The version I'm actually using is 10.5.1.

    After a second look, the console messages do not relate to the problem I reported. They relate to another lockup problem I'm having after moving from Tiger to Leopard.
    Nevertheless, the description of the problems I'm having with the Verify and Repair functions of the Disk Utility is accurate. I had absolutely no problems when I was using Tiger.

  • Slow Disk Permission Verify and Repair

    Is it just me, but in leopard 10.5.3 and 10.5.4 the disk utility permission verify and repair takes way longer than it did in tiger. Its like 10-15 mins to complete now. Am I the only one? or am I crazy?

    Is it just me, but in leopard 10.5.3 and 10.5.4 the disk utility permission verify and repair takes way longer than it did in tiger.
    Mac OS X 10.5 consults ACLs in the process, which makes it take much longer.
    Am I the only one?
    No.
    or am I crazy?
    No.

  • Disk Utility can't "Verify Disk Permission" and "Repair Disk Permission"

    I booted up the Leopard 10.5.5 server from the Install Disc, and tried to do disk checks on all drives using Disk Utility.
    When the system drive was selected all the "Verify Disk", "Repair Disk", "Verify Disk Permission" and "Repair Disk Permission" functions are able to perform, however, if the non-system drives are selected only "Verify Disk" and "Repair Disk" are able to perform, the "Verify Disk Permission" and "Repair Disk Permission" are GRAYED OUT ! and UNABLE TO perform the permission check and repair!! Any idea ?

    Hi, I'm having a problem could be related. I've a 3 years old Xserve (not intel) with 3 HD managed by the apple original RAID board, all that running Mac OS X 10.4.
    I remotely manage the server from my mac running OS 10.5.6 and Server Admin 10.5.3.
    Well, I simply cannot propagate permissions because when I do it, Server Admin freezes and i must force it to quit. Obviously, privileges are not propagated.
    All that di NOT happen 1 month ago when i was "happily" running Mac OS X 10.3.x and Server Admin 10.3.x. Upgrading has been a big boomerang.
    Any idea? Thanks

  • Disk Utility/verify and repair grayed out, using startup disk

    I'm frustrated. I'm trying to repair my hard drive. I restarted from the OS X Mac Mini install CD (holding down the letter C when I heard the chime), opened Disk Utility from the Utilities folder, selected my hard drive image, but the "verify disk" and "repair disk" options are grayed out. I'm at a loss as to how to proceed. Thanks for any help.

    "...opened Disk Utility from the Utilities folder,..."
    If that's what you did then you didn't boot from the disk. You booted from your hard drive and that's why Repair Disk was grayed out. Try again. Insert the disk into the Mac restart and hold down the 'c' key and keep it down until you see the Apple logo and the spinning cog. You'll know you've booted to the installer disk when you need to select your language to proceed with OS installation. Select your language and then from the menu Utilities select Disk Utility.

  • External HD Verify and Repair Permissions...

    I have my iTunes library on an external HD and was wondering if I should verify and repair permissions for this drive as well when I do it for my internal HD??
    Thanks
    Ryan

    No; the information the Disk Utility uses when it repairs permissions doesn't have any entries for disks which don't have Mac OS X installed. Each installation of Mac OS X contains an extra set of permission data in the /Library/Receipts/ folder, and most have an additional list of special permissions to check. These only contain data for the disk or partition on which the receipts are located.

    Hi Jeffrey
    The startup drive can only be repaired from another drive. You have to boot from the install disk.
    To do this: Insert the Install Disk 1 into the drive and then select Restart, then hold down the C key until you hear the chime.
    This will take you to the installation software, but you do not want to install.
    Select your language, then go up to the top menu bar to First Aid and navigate to the Disk Utilities application.
    Select the start up drive, then you click on Repair Disk .
    If it finds errors, repeat the process until it reports no errors.
    Then run Repair Permissions.
    After these repairs, quit the application, and restart normally.
