No need for that on a Mac. The OS can be reinstalled without any repartitioning/formatting.
You have two options when rebuilding a Mac OS.
1. An ovewrwriting install that leaves all apps/data/3rd party extensions & control panels in place. My first choice.
2. A "Clean" install that replaces everything in the System folder. Back those 3rd party extensions & control panels up first. Even with this option the data and apps are untouched.
Make a CD with data files. Rely on the install disks for the apps you have. Remember, a Mac app has possibly extensions, control panels and a prefs file. What you see is what there is. No .dll's blasted all over, no registry, no other PC weirdness...
If I replace an app, first I trash the prefs file and relaunch. Usually fixes the app. Second option is to reinstall, but dump any pref file/extension/control panel when dumping the app.
