Grrrr... this one has me stumped.

So I need an external hard drive that I can run the Leopard install DVD from for my job. I borrowed a Leopard Disk (I bought a copy as well, but my discs are at my parents house) from one of IT guy who specializes in Apple stuff on campus, and copied an image of it to my hard drive.

I saved the image as a "DVD/CD Master," with no encryption and it got a .cdr extension.

Then I made a partition on my FireLite drive, which is 14 GB, formatted HFS+ Journaled and using a GUID partition scheme. I clicked the restore tab, dragged the Leopard Image to the source bar, the 14 GB partition to the destination bar, and clicked restore.

Then it popped up with this strange error message:

"Could not find any scan information. The source image needs to be imagescanned/scanned for restore"

So I went up to the Images menu and selected "Scan Image for Restore...," and then I got a new, even more obscure error message:

"Unable to scan "Mac OS X Leopard Install DVD.cdr. (Invalid argument)"



Does anyone maybe know why this is happening? Thanks

The way I do this is to make a single partition, guid, HFS+ journaled, on the external drive. Insert the optical media. Click on the partition (in disk utility) of the external drive. Go to restore tab. Drag the optical media to the source and the external drive partition (partition, not the entire drive!) to the destination, and click "go" button (I forgot what it is really called, probably restore).

To further clarify pretty much what the guy above said but I found this guide online:

If you have an external hard drive and made an image of leopard copy, but don’t have any dual layered disks lying around, you can always use an external hard drive to install Mac OS X 10.5 Leopard. This is incredibly easy, and works with both USB and Firewire hard drives:

1. Plug in your external hard drive
2. Open up Disk Utility
3. Click on the name of your external harddrive
4. Click on the “Restore” tab
5. In the “Source” field, select the image file (such as leopard.dmg) from wherever it is on your hard drive
6. In the “Destination” field, drag your external hard drive from the Disk Utility drive list on the left onto this field. Of course, if it’s only a partition on the external drive that you want to use, drag only the partition.

Note: anything on the partition will be erased and replaced with the installation files for Leopard. Therefore, it is best to make a partition on the external hard drive which has about 8 gigabytes. Use this partition as the destination so that everything else on the drive remains unchanged.

7. Click on restore. This may take awhile.
8. Once its done, open up System Preferences
9. Click on Startup Disk
10. Select the external hard drive (or partition in it) with the Leopard Install
11. Click Restart. The leopard installation will begin from the external hard drive. This installation is identical to installing leopard with a DVD.

Yeah... I tried all that, but thanks

I think the image file is corrupt. I am going to make a new image, but I am also going to run the "Scan Image for Restore..." before I take the original CD out. One of the IT guys suggested that the original DVD needs to be available to run the "Scan for Restore" command.

I just did a restore right from the DVD. With the drive plugged in and Leopard DVD in the drive, I just dragged the DVD to the source and the drive partition to the destination. Worked just fine and I saved two steps.
