Recovering files from a corrupted USB drive can be a delicate and complex process. The steps below provide a comprehensive guide on how to attempt this recovery, but it’s important to remember that success is not always guaranteed. This guide will cover various methods and tools you can use to try to recover your data.
Understanding USB Drive Corruption
USB drives can become corrupted for various reasons:
Improper ejection: Not safely ejecting the drive from the computer.
File system errors: Errors within the file system structure.
Virus/malware: Infections that damage the drive's data.
Physical damage: Wear and tear or accidents that physically damage the drive.
Power failures: Abrupt power loss during data transfer.
Preliminary Steps
Check the USB Drive on Different Ports and Devices:
Sometimes, the issue might be with the USB port or the computer. Try plugging the USB drive into different ports and computers to see if it’s recognized.
Check Disk Management (Windows) / Disk Utility (Mac):
On Windows, open Disk Management (diskmgmt.msc) to see if the drive is listed. If it’s visible but unassigned, you might be able to recover data.
On Mac, use Disk Utility (found in Applications > Utilities) to see if the drive is recognized.
Software-Based Recovery Methods
