SubRosaSoft.com has released an update to its drive duplication software for the Mac, CopyCatX 5.0. The software uses sector copying and can quickly create an exact duplicate of a hard drive, including a Mac OS X boot drive, or an iPod. It can also clone Boot Camp drives and Windows, TiVo and Linux drives. It uses proprietary resizing technology on HFS Plus drives to recover lost space after a cloning.
