Why do you want to create partitions on external hard drives?

Better data management: Data on external hard drives can be better organized.

Better data security: If you install the operating system on an external hard drive, you can separate the operating system from your personal data, reducing the chance of data corruption.

Simple backup: You can specify a partition to store an exact copy of all important data. When you need to back up all your important data, you can copy the entire partition instead of selecting files or folders.

Multiple file systems: You can create partitions on external hard drives by defining different file systems such as NTFS, FAT32, exFAT, etc. This is useful if you want to use an external hard drive on different operating systems.

Protect sensitive data: You can store sensitive data in a partition and choose to hide the entire partition to restrict other people's access to certain files.

Select the partition type, file system, and partition size, and click OK. To ensure that the partition is 4K aligned, you can select the option " Align to Integral Multiple of Sectors".

Note: You can click the "Advanced" button to set more partition parameters. You can set beginning and ending cylinders, beginning sector, and number of sectors. For GUID partition tables, there are more partition Settings.

Step 3. Click the Save All button to save the partition to current partition table and format the partition.

A newly created partition is not immediately saved to hard drive because it is temporarily created in memory. Therefore, you need to manually save the partition to partition table before you can see it in Windows Explorer. This is done to prevent data loss due to improper operation.

Method 2. Create new partition on the existing partition

DiskGenius has the ability to create new partition on the existing partitions by splitting one partition into two without losing data.

Step 1. Right-click the partition and select Create New Partition.
