At present, the USB drives and Pen drives are very popular storage devices. They have the ability to double up your storage so that you can save movies, photos, videos, etc. or use them as a backup drive, OS boot volume, or for file sharing among various devices.

But the complexity lies in the situation when you want to use the same USB/Pen drive for a different system. To do so, the formatting of a USB drive is required so that the device has a suitable target environment for the new system. Formatting also comes with great benefits which we are going to discuss in this article.

So, let’s start with the reasons why you would want to format USB and then we will move on to the methods you can use for formatting and un-formatting your device.

Part 1: Reasons Why You Format USB

Before we get to the reasons, let’s take a look at the different formats which are available for the Windows system. When it comes to the Windows USB disk format, there are mainly four types of the file system. Every file system has its own list of benefits. Some basic information about formats is given below:

NTFS File System:

With the NTFS file system, you get better disk space management and less wastage. It has file encryption which keeps the files secured and increase reliability. The files are compressed by this format in order to save disk space. It is typically used to read/write files which are larger than 32 GB.

FAT & FAT32:

If you choose the FAT or FAT32 file system, you will get a faster performing USB with quick disk scanning features. It is compatible with almost all Operating System and that’s why it is widely used as the common format for various drives. In this file system, less space is dedicated to the file system data which allows more space for additional data.

But keep this in mind that this file format is not available for the USB flash drives which have capacity more than 32 GB.

exFAT:

The exFAT file system has the ability to create partitions which can be larger than 32 GB. It offers better disk space management. Users can read/write files which are larger than 4 GB.

These file formats are used according to the needs of users. Generally, it is advised that when you are formatting flash drives or pen drives, the NTFS system must not be used. Using the exFAT format is more appropriate for such devices as it combines the essential features of FAT and NTFS system in an optimal way.

For compatibility reasons, FAT32 format is popularly used as it can be used on every platform.

Why You Format USB?

We have already established the fact that the USB drives and pen drives are one of the most useful portable storage devices which are used for file sharing, backup, etc. But every now and then, they need to be formatted. The reasons why you need to format the USB or pen drives are listed below:

  • When you want to add new files in the drive and there is no space left. So, instead of deleting files one by one, it is ideal if you format the whole drive. As you are formatting the drive, you can also change the file system if you want to.

  • Formatting is also recommended for portable storage devices as they have higher risks of being exposed to viruses or bugs. A complete format will remove all the files, errors, and bugs entirely. And your drive will be as good as new.

  • Upgrading your system is also a very good reason for formatting. When you are getting a new OS, it is likely that you will need a file system which is optimal for the OS for better performance.

Just keep this in mind that formatting doesn’t always mean that you need to change the file system. Sometimes, formatting USB drive just stands for deleting the existing files on a USB drive and making space for new files.

Part 2: How to Format USB Drive/Pen Drive
