We recommend! EASEUS Partition Manager enables you to configure and manage partitions on your hard drive(s). You delete or format, and also resize and move your partitions. If you do not have any free disk space you can reduce the size of an existing partition, and use the unallocated disk space to create new or enlarged partitions to better manage your data. In addition, you can view disk and partition properties, set an active partition, change drive letters and more. EASEUS Partition Manager can be run from within Windows, but also includes an option to create a bootable CD, that allows you to manage your partitions before Windows loads.
EASEUS Home Edition is a free download for personal use on Windows XP and 2000 SP4 only.
Looks good, but since I use Windows Vista I prefer to use the inbuilt option provided for partioning systems.
