Disk Utility's Error "Scan image for Restore" process doesn't finish in Mac OS X 10.3

Solution

As a workaround, you can either: 

• Create a disk image, using this method in Disk Utility: From the Images menu, choose New > Image from Folder, or...
• Open Terminal and type this (which is equivalent to "Scan Image for Restore"), then press Return:
