How to Format USB Drive

The correct formatting of your USB drive is essential to ensure that it is compatible with your Phrozen 3D printer.

Phrozen 3D printers only support USB drives that are formatted in FAT32 with an allocation unit size of either 2048 bytes or 4096 bytes. In this article, we will guide you through the process of formatting your USB drive for use with your printer.

The formatting process will erase all data from your USB drive, so it's essential to back up your files before proceeding. If your printer cannot recognize USB, please make sure that your USB is formatted as FAT32, and has a capacity of either 2048 bytes or 4096 bytes.
