Introduction
A corrupted USB drive can be a nightmare, especially when it contains important documents, photos, or work files. Whether due to virus infections, power failures, improper ejection, or physical damage, a corrupted USB can make files inaccessible or disappear completely.
But don’t worry! Your data isn’t necessarily lost forever. There are several methods to recover files from a corrupted USB drive, and this guide will walk you through step-by-step solutions to retrieve your valuable data.

Understanding why your USB drive is corrupted can help you prevent data loss in the future. Here are some common reasons:

Removing a USB drive without safely ejecting it can corrupt its file system.

USB drives can develop bad sectors or file system corruption over time.
5. Physical Damage
If your USB gets bent, dropped, or exposed to water, data loss may occur.
How to Recover Files from a Corrupted USB Drive
