Boottable DMG Woes

alright I have a boottable dmg dvd, which I need to burn. Now I know that I must use disk copy, which is fine. whenever I try to burn the disk, it gives me a dreaded device drained its buffer without burn protection. if I burn the same image on toast, its fine exept, it isnt bootable. ive tried 4 different media types of dvd-r (Rytek G4, Memorex, Maxell, and Verbatims) no avail. I know the burner is good because it works fine in toast, and its the same pioneer 106A, that I had on my pc just a couple of months ago. any help with this little conundrum, would be greatly appreciated.

P.S.
Ive fixed permisions on the drive aswell as repaired the disk and zapped the pram I even defraged it and ran tech tool pro. Heck I even reinstalled osx and nothing
 
try to use disk copy but without monuting the image
i.e: just choose the image without mounting it.
if it was not an image
use toast with copy command
dont use mac volume just copy..
good luck
 
Have you tried burning at 1x? That "buffer under-run" message
says you're not feeding data to the drive fast enough, so slow
down the drive.
 
I have tried burning it at 1x and same problem and I doo not mount the image before I burn it, toast will not make bootable discs.
 
well im trying to make a copy of the panther disc that came with my g5 but it doesent really matter because I cant burn anything using disc utility no matter what dmg I try to burn it always fails I can only burn using toast.

This puts a sharper point or at least a different point on your question.
  1. What version of OS X are you using?
  2. What modelf a Mac do you have?
  3. How much RAM?
  4. How big is the boot drive?
  5. How much free space is on the boot drive?
  6. Is the DVD burner factory installed?
  7. If it is not factory installed, what make and model is it?
  8. Is it internal or external?
For what it is worth I have not heard of anyone successfully creating a bootable OS X DVD or CD from images or any other way, using Disk Utility, Finder, or Toast. The sole exception has been images created with BootCD and I do not know what BootCD does that makes it work.
 
I suspect you've done something terribly stupid and deserve to die -- Joking!!!

I know it can be done because I've done it. I'm staring at three Imation CDs that
are copies of the Panther retail install CDs. I did it creating a new image in Disk
Utility with the "CD/DVD Master" option. And I burned those puppies at max speed.
From Disk Utility.

But that's CDs. Maybe DVDs are different.
 
I make copies of all my OS CD's using Toast with no problems, and they are bootable.
 
Strange... I can make a bootable copy of any retail bootable OS X CD. I use backup copies of my Panther install disks, Diskwarrior, and TechTool, and each of them boot flawlessly.

My procedure is this:
1. Insert bootable CD to be copied.
2. Leave it alone. Don't open it. Don't go looking around at the files on the CD. We're making a copy, not exploring.
3. Open Disk Utility.
4. Select the volume name of the bootable CD.
5. Select: Images > New > Image from [volume name] (the very last selection in the menu)
6. From the resulting window, select: Image Format: DVD/CD master, and Encryption: none
7. Name it and save it. It doesn't matter what you name it -- the name of the resulting burned CD-R or DVD-R will be the same as the original CD or DVD, regardless of what you name the image.
8. Let it make the image.
9. Take out CD/DVD, insert blank CD or DVD, highlight the newly made image in the sidebar and click "Burn."

Works every time.

If Disk Utility doesn't work for you, I've done the same thing with Toast: just select the "Copy" tab, select "CD/DVD Copy" from the slide-out window, and let it make the image. Then burn the image with Toast...

You say that you can't burn at all with Disk Utility, which is strange. If it's the Apple-supplied burner, then that would indicate something very wrong with either your hardware or software. If it's not the Apple-supplied burner, then there are programs available that will help Apple's software "see" your drive, if it doesn't automatically.

I hope that helps...
