Before you start - it is recommended to do a disk clean up, get rid of unnecessary files and defragment your hard drive to create as much continuous free space as possible. If your drive is very fragmented, you may want to defragment twice.

The partition table editors allow you to create, resize, move, concatenate, copy, undelete (unerase) the partitions that you have on your hard disk (or hard disks). For example, if you wish to create more partitions from the existing one (or more) that you already have on your disk, these tools will allow you to resize the existing partition to make space for more partitions (without losing your data that is currently on your existing partition), as well as assist you in creating (and sometimes also formatting) new partitions. Some of the tools may have the ability to slide your partition, that is move your existing partition from one location on the disk to another location, without losing data, as well as convert a partition from one type to another (for example, converting from NTFS to FAT32 or vice versa).

Still others may be able to help you recover partitions that you have already deleted, that is unerase or undelete partitions.

There are free tools and commercial tools. Among free tools linux bootable CD are the most reliable.  Among the commercial tools to manage your partitions the best known is Symantec's Norton Partition Magic. among most interesting features:

[Aug 23, 2007] Help2Go - How to Repartition Hard Drive without Reformatting

When you buy a new computer, the hard drive partitions are usually already set up for you. If you put in a new hard drive, you need to decide on the partitioning at set up time. The problem with both of these situations is that things change. You may decide you don't want everything in one big partition for a variety of reasons, but Windows gives you no options for changing your partitions other than reformatting and losing all of your data. There are excellent programs, like Partition Magic, that will let you resize and create partitions without losing data. But Partition Magic costs around $60 and it isn't a program you are going to use everyday.

There is a way to change your partitions without reformatting and without buying any additional software.

It uses a Linux live CD to boot your computer and prepare for a Linux installation. Don’t worry; you are not actually going to install Linux. Every Linux CD includes a program to resize your Windows partition to make room for Linux because Windows usually takes up the whole hard drive. Once we create the space for Linux, we can actually format it as a Windows partition, either NTFS or FAT32.

First, you need to download the Linux live CD. I recommend Simply MEPIS 3.3, available here: http://iso.linuxquestions.org/distro.php?distro=11  . These directions will assume you are using Simply MEPIS. Download the ISO and burn it to a CD as an ISO image. Check your CD burning software for info on burning an ISO. Once you have your CD, you are ready to begin.

Before you start - it is recommended to do a disk clean up, get rid of unnecessary files and defragment your hard drive to create as much continuous free space as possible. If your drive is very fragmented, you may want to defragment twice.

WARNING- backup all important files. Although unlikely, it is possible to lose data. Even the programs like Partition Magic give you this warning.

Set your computer BIOS to boot from the CD drive as the first option. Most computers get into the BIOS by hitting the DELETE key during start up. The start up screen will usually tell you what to hit to enter set up. Look for something that deals with boot options; it is often under advanced bios options. Boot from the Simply MEPIS CD, choose the 2.6 option unless you have a CPU under 1Ghz. It will take a couple of minutes, but you will eventually have a sign in screen. Sign on as root with the password as root. It will boot to a red MEPIS Linux screen (actually running from the CD)

How to partition and format a hard disk in Windows XP

Ranish Partition Manager
Ranish Partition Manager is a hard disk partitioning tool that allows you to create, copy, resize primary and extended partitions. The later versions of the Partition Manager (2.43 and above) apparently allow you to work with up to 30 primary partitions. Also available from that same site is the XOSL (Extended Operating System Loader) Boot Manager that gives you the ability to choose which operating system (OS) you wish to boot from when you start your system. I think it works under DOS, so you can simply put it on a DOS startup disk, reboot to the disk, and work on your partitions from there.

 

Free Partition and Hard Disk Backup and Imaging Software

Free DVD and CD Burners and Copying Software

Free Defragmentation Programs / Free Defrag

Etc

Partition Logic 
Partition Logic allows you to create, delete, format and move partitions and modify their attributes. It can also clone hard disks, that is, make a copy of an entire hard disk onto another (possibly new) hard disk. It boots from a CD or a floppy disk and runs as a standalone system. At the time this was written, it has some limitations, including the ability to only format FAT partitions, the inability to partition SCSI hard disks, the lack of support for USB mice and keyboards, etc.
SwissKnife 
SwissKnife is a Windows program that allows you to create and format partitions on fixed or removable disks as well as change cluster size during formats.
SystemRescueCD
SystemRescueCD is a bootable system rescue CD-ROM for PCs containing utilities that allow you to manage and edit your hard disk partitions (GNU Parted and QTParted), image your hard disk partitions (Partimage), a partition table backup and restore utility (Sfdisk), various file system tools that allow you to format, resize and edit existing partitions on your hard disk. It does not depend on the operating system you have installed on your hard disk - the CDROM is self-contained and is designed to serve as a rescue disk. There is also a version for the blind (it incorporates a speech reader).
Ultimate Boot CD
Ultimate Boot CD is a bootable CDROM for PCs that contain a variety of software for diagnosing and fixing problems on your computer, managing your hard disk partitions (including creating, resizing, copying, moving, etc), imaging or cloning your hard disk partitions (it includes Partition Saving, see elsewhere on the Free Hard Disk Backup and Image Software page, resetting your (forgotten) password on NT, Win2k, or XP, scanning your hard disks for viruses (it includes some free antivirus utilities), etc. The software included on this boot CD include a number of those already listed on this page.
The Partition Resizer
The Partition Resizer resizes and moves your existing partitions for hard disks up to 2 TB (that is, 2 terabytes). It can handle both primary and extended partitions. It is able to move your data (where necessary) so as to make space for (say) an expanded FAT which may be needed if you are increasing the partition table. You can resize (expand or shrink) or move FAT partitions (including FAT32 partitions) and move NTFS partitions (though not resize). The program is a DOS program, and you can put it on a startup disk, reboot to it, and work on your system from there.
Diskman
The author calls Diskman a "hard disk manipulation program". It essentially allows you to create, format and manipulate partitions, backup and restore long filenames, as well as search and edit data on a hard disk. It has a scripting language that you can use to automate the things you want to do. It supports FAT partitions. The current version (at the time I write this) is a DOS program.
NTFS Resize
NTFS Resize is a Linux program that non-destructively resizes NTFS partitions (enlarges and shrinks). It supports all NTFS versions, including those created and used by Windows NT, 2000, XP (both 32-bit and 64-bit versions), 2003 and Longhorn.
TestDisk
TestDisk is a tool to check and undelete partitions. It essentially searches for lost partitions, and allows you to repair errors in the partition table, create a partition table, create a new MBR, etc. It works with FAT32, FAT16, FAT12, NTFS (Windows NT, If you have accidentally lost (or deleted) a partition, you might want to try TestDisk to see if it can find the partition and recover it. 2000, XP), ext2, ext3, BeFS (used by BeOS), BSD disklabel, CramFS, IBM Multiboot, JFS, Linux swap (versions 1 and 2), NSS (Netware), ReiserFS 3.5 and 3.6, and XFS. The program runs under DOS, Windows 9x/NT/2000/XP/2003, Linux, FreeBSD, and Sun Solaris. It is licensed under the GNU GPL.
Extended FDISK
Extended FDISK allows you to create and delete partitions and logical disks on your hard disk. It appears to come with a boot manager (that allows you to choose between multiple operating systems when you boot).
FreeDOS' FDISK
The FreeDOS FDISK supports hard disks of up to 128GB. You can use it to create and delete primary and extended partitions. It works under DOS (FreeDOS, MSDOS and PCDOS).
FIPS
FIPS supports the non-destructive splitting of hard disk partitions. The program is distributed under the GNU GPL.
