How to recover files from a damaged usb？

​USB flash drives are essential for storing and transferring data, but they are also prone to damage due to physical wear, corruption, or accidental formatting. When a USB drive becomes damaged, accessing important files can be challenging. However, there are several methods to attempt file recovery before considering the drive irreparable.

USB Drive Damage

Before attempting recovery, it’s essential to determine the type of damage. USB drives can suffer from:

Physical Damage: Broken connectors, internal component failure, or exposure to extreme conditions.

Logical Damage: Corruption, accidental formatting, file system errors, or malware infections.

Bad Sectors: Damaged storage sectors preventing data access.

Precautions Before Recovery

To improve the chances of successful data recovery:

Stop Using the USB Drive: Avoid writing new data to prevent overwriting lost files.

Check on Another Computer: Sometimes, the issue is with the USB port, not the drive.

Inspect for Physical Damage: If the drive has visible damage, professional recovery services may be necessary.

Use a Different USB Port or Cable: Connection issues might be causing detection problems.
