Causes of Reduced Capacity

Partitioning and Formatting Issues Incorrect partitioning or formatting of the USB drive can lead to reduced capacity. In some cases, partitions may be created or resized improperly, causing the drive to show less storage space than its actual capacity.

Hidden Partitions Hidden partitions created during the manufacturing process or by certain software utilities can occupy space on the USB drive, reducing its available capacity. These hidden partitions may not be visible through standard file management tools.

File System Limitations Certain file systems, such as FAT32, have limitations on the maximum partition size they can support. If the USB drive is formatted with such a file system, it may not be able to utilize its full capacity.
