Is there a way to save a disk image of Leopard onto an external HD (using another computer with a drive that will read the disk), then install Leopard from it (the external disk)?
Received the Leopard installation disc by fedex today. My MacBook will not recognize the installation disc and after some attempts and noises simply spits it back out.
I too am looking for a fix.
Just got my copy. Same problem... reads the disc and spits it back out. Put it in a friend's Mac Book, and it reads it just fine. Put other discs into my MBP and they all work fine. Trying to work this issue out as well.
Similar problem here. MacBook Pro - fails during install as its verifying the DVD - about 53% of the way thru - tried to copy disk with DiskUtil but that fails with an I/O error.

MacMaul:
There's an article on MacFixit about doing just that:
Yea, it kept rejecting my cd too, but then it finally accepted it. When it did though, it still wouldn't install it. Then it froze when it tried and restarted. Now it won't accept the cd again and my computer will not fully boot up properly. It stops at a blue screen. How can I just get back to my old version of Tiger?
My mac is a power PC G4. I insert CD, double click on install and click restart. It restarts and never gets beyond the gray screen with the spinning beachball. Holding down C did nothing different.
You can put me down as another victim. Put the disk in my MacBook Pro, it crunches for a while and spits the disk out. No previous problems with any kind of DVD or CD. Put in my PPC iMac and it mounts without problems.
Ok. This is going to sound weird but, I had the same problem as many of you. My MacBook Pro would not mount the Leopard disc, it would just spit out the disc every time I tried to insert it into the drive.
Nothing I did would make it work until I just happened to do this:
Just on a whim, I restarted the MBP into Tiger and then put in the Leopard disc. Once the Leopard disc was in the drive, I held the MBP upside down with the screen open. The disc mounted! I put the mac on the desk and I double clicked on the "Install Mac OS X" icon, put in my password and the mac restarted. While it was restarting I held it upside down again while it booted off of the DVD. After it booted into the installer I had it verify the DVD, which it did successfully.
Right now Leopard is still in the process of installing. Can someone else try this and let me know if it worked for you?
Interesting idea, and glad it worked for you, but unfortunately yours seems to be a random lucky case... tried your rather unorthodox technique and it didn't work.
Has anybody else tried a DVD disk cleaner? It solved my problem with a G4 iMac spitting out the leopard DVD ... BTW, installation on my Intel iMac and Powerbook worked without any problems.
Update: it does appear to be luck for that. After some twisting, turning, and squeezing, managed to get the disc mounted inside 10.4. However, I wasn't able to replicate it during the disc boot or afterwards.
I, too, have a MBP Intel in which the install CD doesn't work. I am currently installing on my old PowerBook PPC and it's going fine. This is the second disc I tried - I returned the first one already at the Apple store and the second one has the exact same symptoms: it makes a klunking noise and attempts to read the disc, without success.
I'm wondering if there is some commonality in the DVD drives which are having trouble? Sounds like a lot of us are MBP people.
