While most drives come without partitioning, you can do it yourself on your computer without special tools other than what’s available in Windows or Mac.

Do I Need to Partition My External Hard Drive?

Your hard drive will work just the same whether it’s partitioned or not. However, you have fewer options and less security with a drive with only one partition.Like many computer processes, partitioning a hard drive takes some work but offers significant benefits. The only real drawback is the time it takes to learn to do it. Once you’ve sat down and partitioned your first drive, you’ll be able to do it repeatedly. It’s well-worth learning now to have a lifetime of better hard drive management. 

Why Should I Partition My External Hard Drive?

How to Partition Your External Hard Drive on Windows?

Before partitioning your external hard drive, ensure it’s connected to your computer and appears in Windows File Explorer.

Security Purposes: Partitioning a hard drive can help you protect your data in the event of file corruption. Hard drives have a tiny directory file that stores the location of all the other files in that partition. If it is damaged, you may be unable to access the things stored on that specific partition. Keeping a separate one means you’ll have another index file to find what’s saved on the different partitions. Software Backup: Your data may be simpler to back up if you store it in specific partitions. For example, I don’t need to back up my game files, temporary downloads, the software I’ve tested, or my operating system. Those can be redownloaded from the internet if I reinstall my operating system. It takes a lot of time and space to back up every file on my computer, so I have a single partition with things I want to save, like pictures, videos, and documents. Backing up only that partition makes it much simpler to keep my files safe.OS Backup: You can create a backup of your operating system on its own partition if desired. When your primary operating system needs to be replaced, you’ll have the files on the recovery partition ready to install. 

Ultimately, partitioning your hard drive is a  good choice if you think any of these reasons would benefit you now or in the future. It may not be as beneficial if you only use a drive to store data and you want to keep all your data backed up. When the format is finished, you’ll have a new partition. It will appear to look like a separate disk in Windows Explorer. However, it is the same disk split into different chunks.

What File System Should I Use?
