ML DP4 too big for DVD?

[LegendKillerUK]

Hi all,

Odd problem but Disk Utility in Lion 10.7.4 is telling me that none of my DVD are large enough to fit Mountion Lion DP4 - despite the image being 4.3GB and the DVD able to fit 4.75GB.

I've tried with 10 of my blank DVDs and I know they aren't at fault. Anyone had this issue?

Try a dual layer DVD or a USB memory stick. or even a partition on your hdd.

Been that way since Leopard at least that I know. Dual Layer DVD.

Lion can use a standard DVD-R, no need for Dual Layer. I guess Mountain Lion bloated out a bit again.

I would recommend an 8GB memory stick or fast SD card to put the Mountain Lion install image on.

Well alright. I didn't know since I was on to mounting zip drives by then but I remembered Leopard needed a dual layer as well

I can second the USB drive idea. Thats what I did with Lion, it makes reinstall a lot faster. You can get them online for under $20.00.

$20 for an 8 GB flashdrive? That's too much, I can get one from Newegg for $6, or run to a Best Buy and get one for about $8.

Primary culprit might be the new installation languages. There may be a way of trimming those out of the image before burning if you really need to have this on DVD.

Try this in a Terminal window:

hdiutil makehybrid -hfs -o <path-to-destination-dmg> <path-to-source-dmg>

This optimizes the dmg, so that you can burn it on a DVD.

Here is an example for the Lion InstallESD.dmg:

hdiutil makehybrid -hfs -o ~/Desktop/InstallESD_ready2burn.dmg /Applications/Install\ Mac\ OS\ X\ Lion.app/Contents/SharedSupport/InstallESD.dmg

Apple used the same technique for CDs in Disk Utility, but i think they removed the "optimization" option for DVDs. That is the reason why i use hdiutil. DL-DVDs are probably the easiest solution.

This worked great for me thanks!
