If you've ever had to reinstall OS X, the chances are that you have used the system supplied by Apple installation disk that came with the Mac. But what to do if you lose the DVD, or it becomes unreadable, or worse - your SuperDrive does not work? Have a backup of your system installation disk could save your bacon.
Instead of simply copy another disk system setup program, you can create a Setup program from the USB flash drive similar to that provided with the most recent of the MacBook Air. You will get an installer that scratch, is easier to transport and much faster than an optical disk. We have found the time to install decreased 33% when using the method of the flash player.
The process of creating a flash drive system setup is simple. You will need the installation disk original, a working DVD player and a flash drive with a minimum of 8 GB of storage capacity for the Snow Leopard (or 9 GB) If using Leopard, since it calculates the size of file differently. All data you have on the flash drive will be erased in the process, so back something that it is important to you.
