How To Partition An External Hard Drive in Windows 7

Creating external drive partitions is extremely easy to do in Windows 7. Partitioning becomes essential when a user either wants to remove data from the drive or change the file system format so the drive is compatible in Windows. Windows NT and up primarily use the NTFS file system format.

The basic idea behind creating multiple hard drive partitions is to allow different aspects of the drive to be assigned to different functions. Many people will have a partition for music and another partition for video. Others will separate partitions to serve specific functions such as a primary bootable partition and a system partition.

No matter the application, using the built in Windows 7 partition manager is easy to do and this guide will walk you through creating your own partitions on an external USB hard drive. This tactic is popular for users creating a partitioned drive for a friend or family member prior to giving it to them to use.
