CopyCatX uses sector copy, and skips blank space during the duplication process to increase speed. Additionally, the software offers a backup function that doesn't require a destination drive as large as the original. CopyCatX 3.0 is available for $80 via download, and requires Mac OS X 10.3 or later.

CopyCatX 3.0 offers cross-platform device copying, enabling a Mac to clone Microsoft Windows, TiVo, and Linux drives. The application can perform perfect cloning to preserve every detail of the original drive or volume, and includes proprietary resizing technology to regain lost space after a volume copy.
