Anyone successfull made backup copies of their MacBook Pro DVDs? I normally do this for my PowerBooks so I have a spare set with me in case I need it while traveling. I normally use Disk Utility to make a disk image then burn it. Works fine on the PowerBook.

On the MacBook Pro, I make the disk image (as a DVD/CD disc master as normal) but I when I try to burn it and insert a blank DVD it tells me there isn't room. Any clues anyone?

Dual layey dvd, single layer dvd burner?

bcaslis · Mar 20, 2006, 01:32 PM

I don't think so. I know the dual layer is used for video DVDs, but I don't think Apple uses it for a data DVD. If I select the original DVD it shows up as 4.8GB.

4.8 is too big for a single layer DVD--that's why you can't make it fit w/o a dual-layer one.

Thanks for the info. Well, that's a pain! Is there any way to tell if a DVD is dual layered other than the size of it? Seems painful that there isn't a way to copy a boot disk!

You can, but it will take plenty of HDD space.

It involves making an ISO of the disc (which Disk Utility calls CDR); mounting the image as read/write through the terminal ( hdiutil mount path/to/image -readwrite ); dragging out unimportant software (like the developer tools; and burning the modified image.

The latest Powerbooks and G5s both shipped with Dual-layer install DVDs.

The problem is that the MacBook Pro only has a single-layer burner.

You can easly copy the discs by putting them in a PC with a dual layer drive, like i did or you can try a shrink program. don't know if you can get one for Mac. Or is it possable to over burn from .7 to .8?

You're gonna need a dual-layer burner in the future anyway, best to assemble a firewire case and insert the burner, for approx total of $100. Try newegg.com

You can open a disk image of it with pacifist and delete unneeded installers to make it fit on a 1 layer DVD!

I thought pacifist worked with packages, not disk images. Are you sure?
