Best Free Partitioning software is Ranish Partition Manager, and it's DOS based tool without any Graphics, but it's a very good tool and fits on a Floppy!!!!

Other Partition softwares like Norton/PowerQuest Partition Magic and Acronis Disk Director , 7-Tools Partition Manager r Windows based graphical partition tools with more advanced options....
but using demo of Partition Magic, Disk Director, u can not create/format any partitions, but u can only view them....
but u can use the Demo of 7-Tools Partition Manager which allows u to create, format, delete, hide/unhide, mount/unmount, view sectors (read/write access to any sector). Other functions (convert, resize, any operations with active partitions) aren't working in demo version......
