6 Best Free USB Formatters for Windows 11/10/8/7

What Does USB Formatting Do?

All storage devices, including the USB drives, need to create partitions so that they can store data. In most cases, a USB drive comes with only one partition. Formatting a USB means formatting the partition on the USB drive.

The formatting process usually includes deleting data, creating a new file system, and assigning a volume label and cluster size.

If you perform a full format, it will scan the drive for logical bad sectors and erase data by writing zeros to the drive.

Why/When Do You Need to Format USB Drives?

In general, you may format USB drives for the following reasons.

• Clear Data: Formatting a USB drive can quickly delete all data. Compared to deleting files one by one, formatting is more efficient.
• Protect Privacy: Full format can erase data, making data unrecoverable. If you need to use a USB flash drive on a public computer or lend a USB flash drive to someone else, you can perform a full format on the USB to prevent a potential data breach risk.
• Improve Compatibility: Different devices and operating systems support different file system formats. If the file system of the USB drive is not compatible with the target device, formatting is necessary.
• Restore USB to Normal: During the use of a USB drive, some errors may occur. For example, the USB drive becomes RAW, unrecognized, and inaccessible, or shows the wrong size. Then, you can format the USB drive to restore it to its normal state.

What’s the Best Format for USB Drives?

The best format for USB drives depends on your purpose for using this USB drive. For example:

• APFS and HFS+, if you use the USB drive on a Mac PC frequently.
• NTFS, if you use the USB drive on a Windows PC frequently.
• FAT32 and exFAT, if you need to use the USB drive on various operating systems and devices.
• FAT32, if you use the USB drive to flash BIOS or make a Windows installation USB drive.
