Formatting a SanDisk USB drive is a straightforward process, but there are various details and considerations to ensure it’s done correctly.

USB Drive Formatting

Before diving into the steps, it’s essential to understand what formatting a USB drive does. Formatting prepares the USB drive for use by erasing all data on it and setting up a file system that the operating system can recognize.

File Systems:

FAT32: Compatible with almost all operating systems and devices but has a maximum file size limit of 4GB and a volume size limit of 2TB.

NTFS: Supports large files and volumes, offers better security features but is mainly compatible with Windows systems.

exFAT: Designed for flash drives, supports large files and volumes, and is compatible with both Windows and macOS.

Preparing to Format
