Disk Utility can't burn DVD !

Hi
I've used disk utility to burn a DVD but it always report this message
" Unable to burn "h-mosl1063.dmg". (the device failed to calibrate the laser power level for this media "
The DVD i am using is :
Princo
DVD - R DL
Dual Layer
8.5GB
And this is my disk burning information :
MATSHITA DVD-R UJ-875:
Firmware Revision: DB09
Interconnect: ATAPI
Burn Support: Yes (Apple Shipping Drive)
Cache: 2048 KB
Reads DVD: Yes
CD-Write: -R, -RW
DVD-Write: -R, -R DL, -RW, +R, +R DL, +RW
Write Strategies: CD-TAO, CD-SAO, DVD-DAO
Media: Insert media and refresh to show available burn speeds
May anyone help me to find what's the reason of not burning ?
Thanks

Hi DaddyPaycheck
I am sorry for being late to reply you, i just was very busy.
Actually, yes, I've tried many types of DVDs, the last one was " Imation DVD+R DL " & it's failed.
In fact, I was trying to burn SNOW-LEOPARD using Disk Utility and others applications, non of them worked.
So, I think the problem isn't in the type of DVD.
I have used another computer to burn the SNOW-LEOPARD and it's done, But i faced a new problem
that is the system doesn't read the DVD and it doesn't show the option of choosing which system I
want to boot ?
I really don't know wether the problem in the SNOW-LEOPARD file that i downloaded or it's is in my
system or in the DVD reader of my MACBOOK Pro.
Really need help !

  • Disk Utility will not burn DVDs

    Disk Utility will no longer burn DVDs. I have tried both Memorex and Verbatim DVD+R DL -- Disk Utility tells me the disks are locked, not writable, capacity 0. These are fresh DVDs right off the spindle. I am, however able to write to these same DVDs using Burn, so it's not a media problem. Tried deleting preferences for Disk Utility, tried using Drive Genius 2 to repair the HD, but it didn't show any problems. Any solution short of doing a clean install of the system?

    Hi-
    Will the drive read any discs?
    Have you tried burning a disc at slower speed?
    Have you tried a different, quality brand of disc?

  • MB pro shuts off after bootup chime,  hd damaged/volumeheader related - disk utility can't repair - how do i recover/backup my files??

    Hi guys,
    My macbook pro late(dec) 2011, doesn't boot up anymore, it just turns off after the chime (whilst a gray bar is loading a bit and then the MB shuts off)...
    This all happened after I upgraded to mavericks, safari and chrome were spontaneously shutting off, my macbook kept restarting (all after recommended app store updates), it had kernel panics etc. Last night after an update it just wouldn't boot up anymore! Pff.. what should i do?
    Disk utility can't repair the damaged HD, it had something to do with volume headers..
    I basically want to access my macbook's files and documents so that i can transfer them onto an external hd or back them up.. i just want my files afterwards i can reformat or whatever as long as i get the files and contents of my hd back..
    Ive read of diskwarrior? Can i burn that on a dvd and insert it into my mac, then start my mac and then it allows me to drag and drop all the contents of my hd onto an external hd?
    I need a genius to help me!! A step by step guide would really mean the world to me!!
    Thanks in advance mysterious genius!!!

    Step 4(a) open Disk Utility from Utilities on the menu bar, then proceed to highlight the external drive in the left sidebar as you say and choosing Partition from the row of buttons that appear top center in the main window of DU.
    5(a) click Restore on the bar of buttons top center of the main DU window, then what you say.  But use the name you have given the external drive in step 4, Mac OS X Extended (Journaled) is the way it has been formatted, use a name such as Backup or something obvious to you.
    Step 7, On the menu bar, click File, then New Finder Window.  In the left sidebar you will see Devices and the internal and external drives will be listed.  Click the name of the external drive and then in the main part of the window you should see the contents of the external drive.  You can click on the folder for Users, then your user name, and see what folders appear...make sure the folders such as Documents, Pictures and whatever else you use appear and have the content you expect to be there.
    You want to be sure all the content has been copied over since the step of erasing the internal drive is going to permanently remove it from that drive.
    And then after step 8, add step 9, from Utilities on the menu bar, choose Install Mac OS X, and if it asks where to install, choose the internal, Macintosh HD, as where to install.

  • Can't burn DVDs properly

    Hi guys,
    I've been burning dvds for a while now, but recently I haven't been able to make ones that work on my finicky Denon player. They work fine on my macbook. Usually, once in a blue moon, I had a disk that didn't work, but recently, none of them are working.
    So here's what I do:
    make an iMovie, then create an image using iDvd. (professional quality).
    Then I burn the image using disk utility with TDK +R dvd. At the lowest speed available.
    Now, they won't load or if they load, I can play the chapters in the middle only (I can't play the ones at the beginning and at the end)
    What I did to try correcting it.
    Clean up my DVD player - opened the top and cleaned the lens with alcohol.
    Try burning another image.
    What I think could be factors:
    Leopard - the images that are not working (I'm almost positive) were made using leopard. I burned an old image (from the Tiger days)today, and it worked.
    End of the stack of DVD. I had 100 DVDs and I probably have 25 left.
    Any other suggestions?
    Thanks in advance, and yes, I will mark it answered when we figure it out.

  • I can not burn dvds anylonger with my MacPro. Why ?

    Hi everyone. I already posted this message in another thread but got no useful replies.
    Configuration: MacPro Early 2008, MacOSX 10.6.8
    I can not burn dvds anymore and do not know why. I can play dvds and cds though!
    The following is the usual error message displaying after clicking the button burn :
    I have run Disk Utility from the Install cd of Snow Leopard and the small things which needed repairs have been repaired.
    I have reset the PRAM and the SMC (System Management Controller). Nothing.
    I have set up a new user account with admin privileges but it did not work.
    Please, note that I am trying to burn the same Kodak Pro dvds for photo and data archival that I burned in the past in the same MacPro.
    I am actually burning my dvds using my MacBook Pro connected with my MacPro through Airport but it's a very slow process, of course.
    Any piece of advice ?
    Thank you !
    Paolo

  • Can't burn DVD, reinstall pkg?

    Dear Friends,
    I have read several other posts with the same problem (can't burn DVD's). I could previously. There were no real solutions just the usual diagnostic suggestions. How about reinstalling whatever package burns DVD'? I have Pacifist. What package would that be? Thanks for your help.

    Dear Baltwo
    Thanks for your reply. I have tried all the usual "voodoo" fixes. The ones you try when you haven't a clue about what might be wrong(disk utility,disk warrior,etc.)
    I tried various versions of Toast, I've tried the built-in burning utilies. This same set-up burned DVD's fine before. I can read them, I can burn CDs, but not burn DVDs. I have been to the apple forums and found similar posts. I am guessing that whatever burns them has been corrupted. Is possible to reinstall just that part with Pacifist? I using OS X4.10 so my original install disk is old(4.3)I'd like to avoid reinstalling that whole old system. Thanks for your help.

  • Can I fix a disk with this message?-Disk Utility can't repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.

    Can I fix a disk with this message?
    Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.

    Some problems can indeed be fixed this way. But working from Recovery_HD or Disk Warrior DVDs and working in the restricted environment those provide can be difficult. You can literally spend days working on this problem (while your regular work is unavailable) only to discover the old drive is unsalvageable.
    There is no way to know up front whether you are facing a major Hardware failure or a minor software glitch, or something in between. Often you are forced to work from the drive you no longer trust. I continue to recommend you do this work from a different, fully functioning Mac OS X booted from a different drive.
    If you have had the foresight to (as The hatter often recommends) clone your virgin install onto another drive for use in such situations, you will be able to recover from such problems in record time. If not, my previous recommendations stands:
    Buy a new Drive. Or  two. Install Mac OS X from scratch on a new drive, and get your Mac running again. Later, you can use the full power of Mac OS X to attempt to rescue your data, if needed. Then Zero the old drive, to see if it can hold data again reliably.
    If the old drive eventually provides some needed data, and is salvageable, Merry Christmas.

  • Can't burn DVD

    Dear,
    I can't burn DVD +R with my macbook pro. Bought verbatim, sony, fujifilm dvd's nothing works.
    An error shows up in toast something like this:
    Sense Key = Medium Error sense Code = 0x73, 0x03
    Kind regards,

    I don't burn dvd's very often, so the challenge is to remember when I do.
    Just remember that a disk image is like a "virtual disc", so you want to make Copy using the Image File.

    Hi,

    My Matshusita DVD unit can read it without problems but when I insert a blank DVD to burn it, Finder doesn't open and I can't do it.

    Please, could you give me some advice?
    Thanks.

  • Using Disk Utility to copy Application DVD or Cd's

    I've always used Toast to make a copy of a software CD or DVD that I've purchased. I store these offsite. Some DVD DL (6-7GB) have problems in Toast. I've started to use Disk Utility - Disk Image. The question I have is should I use read only or DVD/CD master?
    Before you ask, the license policy on most/some software allow the purchaser to do this.
    G5 Dual 2.0   Mac OS X (10.4.8)  

    <font "size=+1">Duplicate a CD or DVD
    1. Insert the DVD/CD;
    2. Open Disk Utility, and select the DVD/CD from the left side list (select the DVD/CD icon on top);
    3. from the DU File menu select New | Disk Image from Disk 1;
    4. Choose to format the disk image as DVD/CD Master, name the disk image and click Save;
    5. When the .cdr file is finished select it with mouse and press COMMAND-I to open the Get Info and check the box to lock the file;
    6. Choose the .cdr file from the left side list, click Burn, and insert a new, blank DVD or CD.

  • 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.

  • IMac Finder cannot see external hard drive but Disk Utility can

    I have a WD external hard drive and it has been attached to my iMac for a year or two.  About two months ago I upgraded to Lion 10.7.5 and hard drive still worked.  Then suddenly about a week ago the iMac no longer sees the external hard drive in Finder.
    I have connected the hard drive to the iMac with different USB cables and into different ports and it makes no difference so deduce there is no issues with the cables or the ports.  I have connected the hard drive to an old Macbook and it can see the harddrive and read some of the info but I really need the hard drive attached to the iMac as I store all my music and photos on the external hard drive.
    I read another thread and someone asked if you can see the hard drive in Disk Utility.  I tried this and Disk Utility can see the hard drive.
    What does this mean?  Any suggestions as to how to get the iMac to see the hard drive so I can access the data on it?
    I dont really know how Disk Utility works therefore if that is any help to me.
    thanks

    Open the Finder.
    From the Finder menu bar click Finder > Preferences then select the General tab.
    Make sure: External disks is selected.
