How to Partition an External Hard Drive in Windows

Unlike internal hard drives, most external hard drives come already partitioned and formatted. However, if you need multiple partitions for your business data, you may need to remove or shrink the existing structure. Windows’s Disk Management utility allows you to do just that through a simple, graphical interface. During the process, you’ll also need to decide on formatting. Using the FAT32 file system will keep the drive compatible with other operating systems, but if you’ll only be using the drive in Windows, NTFS is a good choice.

You may even want to put videos in one partition and photos and documents in another to speed up searches.
