Snow Leopard: Source image needs to be scanned for restore

I was in the middle of taking my official copy of OS X Snow Leopard and restoring a disk image of it to a USB Flash drive (you know, to make installation faster… yeah – that’s the ticket), and I came across this problem I wasn’t used to – Snow Leopard threw an error like “Could not find scanning information for disk image. Source image needs to be imagescanned for restore,” and I was like “Huh? WTF?”

I did a quick Google Search and on the Apple Support Forum someone already answered the question. In Disk Utility (where you’re doing the restore anyway) – select your image on the left, then go up to the Images menu and choose “Scan for Restore” – Snow Leopard will then scan the disk image to make sure it’s okay and everything is ready for restoring. Then you can continue with restoring your disk image as planned.

I definitely was not trying to install Snow Leopard on a Hackintosh computer using this handy guide and command-line free tool. Just saying.
