CopyCatX 4

SubRosaSoft CopyCatX is an extremely fast and easy-to-use utility for duplicating a Mac OS X volume or cloning a complete drive.

It is perfect for: Anyone who wants to upgrade to a bigger drive. Game players who want to make a perfect copy of a drive with all the hidden files duplicated. Systems administrators who need to deploy multiple drives with identical content.
Forensic experts whose job requires identical copies of the original drive. Cross-platform users who need to clone a PC or Linux hard drive quickly and easily. CopyCatX utilizes a method called "device-to-device copying" instead of file-by-file copy employed by most backup software. Using device copy enables you to retain every detail of the original drive, from bootablity to the icon locations. Device copy is also a lot faster than the traditional file-by-file backup. Version 4 may include unspecified updates, enhancements, or bug fixes.
