Partitioning and formatting new hard drives is a pretty straightforward thing. However, repartitioning an existing drive can be a bit trickier, especially if you want to keep the data you have around. Sure, you can always opt to just wipe the entire drive and then partition it, but not everyone would be that open to losing all the available information, and things get even more complicated when you have a massive amount of information that makes traditional backup methods a huge chore.

IPartition is a streamlined macOS utility designed to provide an intuitive and powerful user interface for easily and rapidly partition your Mac’s storage devices, whether they are removable, external or fixed.

This situation is especially pesky since all Macs come, by default, with only one partition with everything on it. Those of users that live and swear by at least two partitions, one for the system and at least one other for information, will instantly format the drive and repartition it. However, many new users start using their machine straight off and are in a bit of a jam when it comes to later partitioning it.

Fortunately, software that can repartition a drive without tossing out all the information on it has been around for quite some time, and iPartition is a fine example.

What it doesiPartition is a program that will let you resize existing partitions, by either shrinking or enlarging them, as well as create new partitions, all this while keeping all your valuable information intact.The program can also do a large variety of other things such as reordering the partitions, and the changing of partition related options.

Everything you do in iPartition is done through a very visually orientated interface, and everything is highly intuitive, provided you have dealt with partitions before and know what they are and how they work.

Resizing existing partitionsResizing existing partitions is made very easy. Simply select the drive you want, then the partition you want changed, then either type in the new desired size in the inspector window, or the partitions tab to visually resize the partition by dragging its end point.

In theory, that is all you need to do, however there are other factors that can make this a bit more complicated.For one thing, you cannot work on the current boot drive. This is an OS X limitation which prevents you from making any changes. So to change anything on that drive you have to boot up from an alternative drive. You can either use a special boot CD, or, if you happen to have another Mac, you can turn the target machine into an expensive external drive using the FireWire Target Mode. Regardless of how you choose to go about it, you must boot from an alternative source to make any changes to your normal boot drive.

Another thing that can interfere with the resizing process, especially shrinking, is fragmentation. While the Finder might report that a volume is half empty, without it actually being an error, there might be information that was fragmented and lies near the end of the volume. This makes it impossible for iPartition to shrink the volume as it would mean losing that information, and the program is designed to keep your information intact.Fortunately the solution is close at hand, and you can easily use a defragmentation utility to move all the information to the beginning of the volume, leaving a nice big, continuous empty chunk of space at the end of the volume, which would allow you to shrink it.

Expanding an existing volume is much simpler since you need free, unpartitioned space for it. Just drag or specify how large you want the partition to be, and, provided that space is indeed available, it will make it so.

Creating new partitionsCreating new partitions is also easy. Tell the program what to name it, what kind of partition you want, how big you want it and where to place it. You can also choose to format the partition, however, iPartition can only format a limited number of different partitions. While you may be able to create a FAT or NTFS partition, the program cannot format it. In fact, the number of partition types that it can format is dwarfed by the number of partitions it can create.

Back-upsThis program works with your information in the most intimate of ways, and, no matter how much care is taken by the developer, there will always be certain risks when meddling with partitions. While resizing of partitions is usually as safe as can be, moving partitions is a bit riskier, even if you only take extraneous factors into consideration. Power shortages, earthquakes and flocks of molting geese can all wreak havoc if they strike while you are performing delicate operations on partitions that are filled with valuable, irreplaceable information. For this reason, backing up is always strongly recommended.

The GoodiPartition makes dealing with partitions easy and as safe as can be. Everything you need is just a few clicks away.

The BadOther than the steep pricetag, there is nothing inherently bad about this application, however, the documentation could be a bit more thorough, and the advanced options could be placed a little out of the way.

The TruthThis program costs a bit much for what it does, especially since there are other programs out there that serve the same function. If you are not bothered by the pricetag, then this program will serve you well, for all your partitioning needs.

About resizing partition in Windows 10/8/7/XP

Resizing a partition is the process of changing partition's size via extending or shrinking it. You can either increase a partition's size or shrink it based on your needs. Besides, you can also split a partition into two partitions or add free disk space to any existing partition.

A partition, also called drive or volume, is a part of continuous logical space on hard disk. A hard drive can be divided into multiple partitions which can be used to store a variety of files such as operating system and personal data. If your hard drive has very large capacity, and you can create more than one partitions on it, so that you can separate Windows, installed application and individual data by storing files on different partitions.

However, when you partition a hard disk, there might be chances that you are not satisfied with the partition size or number the first time you try. For example, one partition might be too small to hold all your data. If your system partition (Windows drive) is running out of free space, computer may slow down or even cause other issues.

How do I resize a partition in Windows 10 for free? Fortunately, resizing partition in Windows 10, Windows 8, Windows 7, Windows Vista and Windows XP becomes a lot easier than previous versions of Windows systems. We can use system built-in tool to resize volume as well as free partition manage to change partition size without data loss. In this article, we'll show you different methods to resize partition in Windows.

There are a number of reasons that users want to change partition size, and here we list the most common ones:

• To make best use of disk space: Due to the daily increasing of data amount, some partition may be full of data, while some partition still has large free space. You can move free disk space between to take full advantage of space.
• Low disk space issue appears: You receive error message from Windows, which says 'You are running out of disk space on Windows (C:). To free space on this drive by deleting old or unnecessary files, click here…' 'You are running out of disk space on Recovery (D:). Click here to see if you can free space on this drive.' Deleting files is not recommended on system partition, for you may delete vital system files and cause system crash. In such situation, you can extend partition to fix the issue.
• There is only one big partition on hard disk. When you buy a new PC, the hard drive is divided into one big partition. You can shrink this volume and create a new partition on unallocated space.
• You want to dual-booting compute. You may want to install another operating system such as Ubuntu on same hard drive, but the partition does not have enough room. Thus you need to extend partition for the installation of new operating system.

Method #1: Resize partition using Disk Management

Disk Management is a Windows built-in utility, first introduced in Windows XP for the purpose of replacing fdisk command. It allows users to view and manage disk volumes on computer. Users can view disk layout, file system, status, capacity, type, etc. Besides, it allows users to create, delete, format extend or shrink partition with easy steps. Now we'll show you how to resize partition in Windows Disk Management.

Step 2. Choose the partition you want to resize, right-click on it and select 'Shrink Volume' option. If you want to increase the partition size, then choose 'Extend Partition'.

Step 3. Input the space you want to change and click 'Shrink button'. When you enter the amount of space to shrink, please note the unit is MB, for example, if you want to shrink 10GB from this volume, you should input 10240.

Method #2: Resize partition with free partition manager

Example #2: Shrink partition without losing data

This tutorial shows you how to shrink a partition without data loss. The disk space shrunk from the disk can be added to other partitions, kept unallocated or created new partition.

Step 1. Right-click on the partition you want to shrink and select 'Resize Partition' from context menu.

Step 2. On the Resize Partition window you can set disk space you want to decrease.

Disk partitioning will delete all current partitions and data before creating new volumes, thus you'll lose all data on the disk which already contains volumes. On this occasion, you need to backup data before repartitioning hard drive. Besides, you also need to reinstall Windows if the disk to be partitioned is the one where Windows is installed.
