Experiencing issues with a corrupted bootable USB drive can be frustrating, especially when it contains important data. Whether the corruption occurred due to improper ejection, malware, or hardware failure, recovering your data is crucial. This guide outlines effective methods and tools to help you retrieve your valuable information from a corrupted bootable USB drive.
Understanding USB Drive Corruption
USB drive corruption can manifest in various ways, including inability to access files, recognition issues by the operating system, or frequent errors during file transfers. Corruption often results from sudden removal during data transfer, malware infections, or physical damage to the drive. Recognizing the signs early can prevent extensive data loss.
Preliminary Steps Before Recovery
Stop Using the USB Drive
As soon as you suspect corruption, discontinue using the USB drive to prevent overwriting data, which can make recovery more difficult or even impossible.
Assess the Damage
Determine the extent of the corruption. Check if the drive is recognized by different devices or operating systems. Sometimes, what appears to be corruption can be a simple connectivity issue.
Data Recovery Methods
Using Built-in Operating System Tools
Both Windows and macOS offer built-in tools that can help repair and recover data from corrupted drives.

Check Disk Utility: Connect the USB drive, open Command Prompt as an administrator, and run chkdsk /f E: (replace E: with your USB drive letter). This command scans and fixes file system errors.
For macOS Users
Disk Utility: Open Disk Utility, select the corrupted USB drive, and use the ‘First Aid’ feature to repair the disk.
