Partition-Saving is awkwardly named but incredibly useful app for transferring the bits of one drive to the space on another drive. It's kind of like Norton Ghost, but free. The utility works in DOS only, and is excellent for any techies. Partition-Saving can also save parts of a drive, like the Master Boot Record or partition tables. The documentation is extensive, and I appreciate the effort, as clearly English is not the developer's primary language. Pretty handy app for freeware.
