I am about to swap hard drives between two systems and will need to install Lion onto each of them, once the hardware is swapped. And to prevent me from accidentally booting either new machine with an incorrect Lion install, I want to wipe the drives as my last action before taking the machines apart.<br />
<br />
How do I do this? &nbsp;If a new OS will be installed on restart, can this be a quick format? What options should I select for this reformat of the two drives?<br />
<br />
Thanks.

Mac OS X is the desktop operating system from Apple Inc., found on Macintosh computers. OS X consists of a Mach/BSD-based kernel, operating system interfaces primarily based on FreeBSD and additional frameworks (written in C, C++ and Objective-C providing user interface and application-level services.

Mac OS X

Apple's early computers ran on a variety of operating systems, including a Pascal version and one based on CP/M, before releasing its ProDOS with the advent of its 16-bit computer. With the release of the Lisa, which had its own OS, Apple and computing entered the graphical age; it was followed by the Macintosh, which offered a series of "System" operating systems. Other Mac operating systems included PowerPC until Apple acquired NeXT and folded it into the Mac OS. Current operating systems for Apple devices are Mac OS-X and iOS.

Apple OS

Programs written for the Apple operating systems are distinguished from software created for other operating systems in that it must be approved by Apple for use on its devices, whether it is from Apple (Final Cut, iWork, Keynote, Logic Pro and GarageBand are popular titles), or is a third party application from Parallels, Nuance, Microsoft and Amazon, among many others.
