Paragon Partition manager

Partition Manager is suitable for both professionals and home users. Basic partitioning operations are: create, format, delete, resize, copy, and mount partitions. You can restore accidentally deleted partitions. It also offers free space redistribution and hard drive defragmenter. Smart Partition technology allows performing all operations without losing a single byte of data. Supported file systems are FAT 16/32, NTFS, Ext2/3FS, Linux Swap, and HPFS. Partition Manager is available in Personal, Professional, Server or Enterprise Server Editions.
Version 8.5 supports Windows Vista.
You mean to say haven't partitioned your hard drive? Why the heck not? Partitioning a big drive into smaller, more manageable parts makes it faster and more reliable.
Paragon Partition Manager includes everything you need to create, merge, defragment, and recover partitions, as well as change their properties. Conveniently, you don't have to quit Windows to run the program. You specify the desired operations within the application and then press the Apply button to carry out the changes. The interface is intuitive. You can resize partitions via a simple drag-and-drop interface. The program includes easy-to-use wizard dialogs for the most common routines, such as merging partitions, redistributing disk space, and recovering a partition.
