This page delivers a comprehensive solution for how to partition hard disk in Windows 10/8/7/XP/Vista without formatting the device, which also meets the demand of creating a partition in Windows without formatting the disk.

Why Do You Need to Partition a Hard Drive

Disk partitioning divides a hard drive into several partitions. Partitions are usually created when the hard drive is first being prepared for use. After a hard drive is divided into partitions, an administrator or power user will be able to resize partition, move partition, split partition, merge partitions, create a new partition for Windows 7 dual boot system and so on because of later changes on the computer or the OS.

So how to partition a hard drive without formatting the hard drive is very important to manage partitions for different uses. How can you partition a hard drive without formatting the device? There are two solutions below.

Solution 1: Partition Hard Drive with Disk Management

Windows 2000, Windows XP or Windows Server 2003 built-in Disk Management has the ability to create a partition, delete a partition, format a partition, change drive letter and so on. If you want to re-partition a hard drive without formatting it, you need to use a third-party partition manager.

Windows Vista, Windows Server 2008 or Windows 7 built-in Disk Management has the ability to shrink s volume, extend a volume, create a volume, delete a volume, format a volume and so on. If you want to extend system partition, there must be some unallocated space behind the system partition. If the unallocated space is clinging to other volumes, how to move volume and let the unallocated space be clinging to the volume which you want to extend? Windows Vista, Windows Server 2008 or Windows 7 built-in Disk Management has no "Move Partition" feature, so a third party partition manager is required.
