Reinstalling or restoring the operating system to a previous state in Mac OS X is definitely something you don't need to perform often, however it seems that the time has finally arrived. As I have a few machines in different locations, I wondered how I could create a backup copy of the original Snow Leopard installation disk in order to keep my original disk in a safe place.
Copying DVDs can be a tricky matter, but thanks to a great tip I found on Walter's blog, I could clone my original disk without any hassle (well, almost, the original Apple's Optiarc drive refused to write to the disk, but my secondary Pioneer drive did the job smoothly).
By the way, if you are experiencing problems with the WiFi connection in your Mac and the Mac is running on top of Snow Leopard 10.6.7, chances are you hit a mysterious bug that seems to affect Macs with this patch level and certain wifi access points. Since I upgraded to 10.6.7 my wifi network has become sluggish if not completely unresponsive.
So now, in order to demonstrate the theory, I need to revert at least one machine to 10.6.6 and see if that does the trick as some users claim, hence the need of using the original installation disk.
Regardless of the final result, the dvd cloning tip is something a mac user definitely needs to know.
