USB drives are widely used for storing and transferring data due to their portability and convenience. However, data loss from a USB drive can occur due to accidental deletion, formatting, corruption, or malware attacks. When files are deleted from a USB drive, they do not go to the Recycle Bin but are instead marked as free space, making them recoverable until they are overwritten by new data.
When a file is deleted from a USB drive, the operating system removes its reference in the file system but does not immediately erase the data itself. Instead, it marks the space as available for new data. This means that recovery is possible as long as the deleted data has not been overwritten.
Common Causes of Data Loss
Accidental Deletion: Deleting files without backups.
Formatting: Formatting a USB drive erases all stored files.
File System Corruption: A corrupted file system can make data inaccessible.
Virus or Malware Attack: Malicious software can delete or encrypt files.
Physical Damage: Hardware failure may lead to data loss.
Methods to Recover Deleted Files from a USB Drive
1. Check for Backups
If you have a backup of the lost files, restore them from your external backup or cloud storage. Common backup solutions include:
OneDrive, Google Drive, or Dropbox
Windows File History
External hard drives
2. Use the Windows Command Prompt (CMD)
The Windows command prompt has a built-in tool called chkdsk and attrib that can sometimes recover lost files.
Steps:
Insert your USB drive into the computer.
Open Command Prompt as Administrator.
Type chkdsk X: /f (replace X with the USB drive letter) and press Enter.
After the scan, type attrib -h -r -s /s /d X:\*.* and press Enter.
Check your USB drive for recovered files.
3. Use File History or Previous Versions (Windows)
If File History is enabled on your system, you may be able to restore previous versions of files.
Steps:
Right-click the USB drive in File Explorer.
Select "Properties" and navigate to the "Previous Versions" tab.
Choose a previous version and click "Restore."
