4/7/2023 0 Comments Install disk creator leopard![]() My intention here is to use the small partition to hold the bootable installer image, and the large partition to receive Time Machine backups from now on. I partitioned the external FireWire drive into two, one a 10GB partition, the other encompassing all the rest of the drive. When the disk image had been created (something under an hour later), I ejected the DVD and proceeded to prepare the external FireWire drive (still using the Leopard Disk Utility). I specified that I wanted a DVD/CD Master with no encryption, and saved the image to the Desktop, calling it LeopardCommercial.cdr. ![]() In particular, two levels appear for the installer DVD in the column at the left side of the DVD: I selected the second level ("Mac OS X Install DVD") so that I could choose File > New > Disk Image From (Mac OS X Install DVD). I inserted the commercially available Leopard installer DVD into the MacBook's optical drive, started up Leopard's Disk Utility, and asked for a New Disk Image from the installer. ![]() ![]() It is booted from the internal drive, running Leopard. It is certainly possible that something odd is going on with some readers' systems, but the fundamental law of scientific proof is that one counterexample is sufficient to falsify a hypothesis, and I have such a counterexample, since I have cloned a Leopard install disk image to an external FireWire drive using Disk Utility in Leopard. These conclusions appear to be incorrect. If my case is generalizable, one won't be able to copy the Leopard DVD disk image to a FW drive using Leopard's DU. I have not found any way to do a successful cloning (restore) to the external FireWire hard drive using only Disc Utilities in Leopard 10.5, so I am still assuming that Apple has put in a copy protection or hinderance to avoid copying/cloning of the install DVD. I have now done further tests to determine that Disk Utility in Leopard does not allow an install disk image to be restored (cloned/copied) to an external FireWire Drive. Part of the reason I was prompted to try this experiment is that we received a couple of emails roundly denying that this was even possible. The instructions have changed a little, so I'm going to explain what I did to perform the cloning. Today, we performed the cloning operation from the commercial Leopard DVD installer, using an Intel machine (recent MacBook) running Leopard. However, up to now we have always performed the actual cloning under Tiger. And a little while ago, we published an article mentioning that you might want to clone the Leopard installer to an external drive. We also used a similar technique during the Leopard beta period, to create a Leopard installer on a partition of an external FireWire disk. A FireWire drive, on the other hand, is fast and reliable, so if you need to reinstall, or install to a new partition, you just boot up from the partition containing the cloned installer and badda-bing badda-boom, you're in the installer ready to install reliably and quickly. A DVD is slow to boot up, and if there is any kind of glitch with the drive or the medium, you may not be able to complete the installation. This is a good idea because the DVD is optical media, and optical media can have problems. In an earlier tutorial, we explained how to clone the Tiger install DVD to a partition on an external FireWire disk.
