Why do we need to partition a Windows 8 or 8.1 hard drive? On the one hand, it is for data safety - if your Windows 8/8.1 hard drive only has one partition including Windows, boot files, programs, documents, photos, and so on, when there is something wrong with your system, all data on the partition may be lost. On the other, hard drive partitioning can make full use of disk space and will be more convenient for us to assort different kinds of files and documents, and make our computer run smoothly.

1. Only one partition on the hard drive.

If there is only one partition on the hard drive, you need to divide more partitions for different uses and data safety. You may assign one as the system partition and the others as data partitions. This could improve the performance of your computer and make you manage your files in a more efficient way.

2. A new hard drive.

Imagine that you just purchased a new hard drive, There is no doubt that the first thing you need to do is to create several individual partitions and store different data. Partitioning in Windows 8 or 8.1 must be easy to achieve with the partition software. That'll guarantee you the good performance of your computer in the future. Also, for further use, the conversion between FAT32 and NTFS must be completely safe.

3. Redistribute disk space.

After installing some applications and Windows updates, system partition (C: drive) may run out of disk space, but there is much more unused space in other partitions, such as D: partition. In such case, you can partition hard drive to make system partition bigger by taking disk space from D: to C: drive.
