In the Bombich Forums is a very helpful thread on how to properly prepare your external HD before cloning to it so that it will be bootable: http://forums.bombich.com/viewtopic.php?t=4084 Beyond that, all that you need is SuperDuper, if that is your backup program of choice. (And it is an excellent choice.) In the event of a misfortune, you can just startup from the backup and use it like you would have the original disk. You can also clone the backup disk to a new disk using SuperDuper. ___________________________________________ Randy B.
