My MBP keeps ejecting my install disks!

Question

I thought I'd make backup copies of my SL disks, but the Machine keeps ejecting them. It reads other disks just fine, including the Tiger install disks off an iMac.
The SL disks will read fine in the iMac, but the MBP doesn't want them!
And once I've solved that, how do I copy them? On the iMac I keep getting the installer if I click on the disk icon.

Answer 1

The SL disks are DL DD DVD's. Perhaps your optical drive is having problems reading those. Take it to an Apple store or AASP.
How to Make a Non-Commercial DVD copy of MAC OS X
Making a DVD Image:

Step 1. Insert the retail Mac OS X Install DVD into your drive.

Step 2. Launch Disk Utility (Applications > Utilities).

Step 3. In Disk Utility, you will notice a white pane on the left hand side. In the pane, select the Mac OS X Install DVD by clicking on it once.

Step 4. Click New Image on the Disk Utility toolbar.

Step 5. A dialog box will appear. Give the new image a name. I used 'Mac OS X Install DVD'. Select the destination where you wish to save it. Leave Image Format at Compressed (default) and Encryption at None (default).

Step 6. Click Save to begin creating the image.

Step 7. Once your image has been created DO NOT mount it. Leave the image alone and proceed to the next section.


Burning the Image:

Step 1. Launch Disk Utility (Applications > Utilities).

Step 2. Click Burn on the Disk Utility toolbar (upper left).

Step 3. Navigate to where you saved the DVD image created in the previous section. Click on the image file, then click the Burn button. Do not drag and drop the image file into Disk Utility during this step.

Step4. Insert a DVD when prompted and proceed to Burn it. (use good quality media).
