Partition Logic is a graphical, easy-to-use partitioning and hard disk management tool for PCs, based on the alternative Visopsys OS. It can create, delete, reorder and move partitions, and modify their attributes, as well as doing things like copying entire hard disks. It boots from a single floppy or CD image. Version 0.57 (freshmeat announcement) has a number of tweaks and some important bug fixes. A change log is here, and downloads are here.
