DiskJockey is a hardware-based hard disk copy and diagnostic tool that enables users to copy or clone the contents of one hard drive mechanism onto another device. Additional space left over on the new device might go to waste because of the smaller partition size, however. Utility developer SubRosaSoft.com Ltd. has addressed that problem with
DiskJockeyExpander, a new US$25 software utility that can recover the unused space. It’s a subset of VolumeWorks, a utility that provides similar functionality for a wider range of hard drive devices.
