How to Fix a Damaged USB Flash Drive: Common Scenarios and Solutions
1. USB Not Recognized
This is one of the most common problems.
Causes

Step 3: Assign drive letter
- Open Disk Management
- Right-click USB → Change Drive Letter
These steps often resolve recognition issues without further action.
2. USB Asks to Format (File System Error)
This scenario clearly indicates file system corruption.
Important
