How do I recover lost files on my USB?

Have you ever accidentally deleted some important data stored on your USB? Or, do you find that USB files get lost for no reason in the use process? What are the causes of USB data loss and how to recover files from USB for free are the issues we will discuss in this article.

Why does USB data get lost?

Apart from files being accidentally deleted, there are several common reasons that can easily lead to the loss of USB data:

• Your USB is unplugged in an improper way. Unplugging the USB during data transfer can easily lead to partition damage, device formatting, etc.
• The USB was formatted accidentally. If the USB is formatted carelessly, all the data saved will be erased.
• Hardware failure. Your USB is malfunctioning or there is a problem with the USB port.
• The USB is infected with a virus or malware, resulting in all files being removed.

✎Notes:

If you find that USB data has been deleted by mistake, you can use the "Crtl + Z" shortcut to undo the previous operation, which is only applicable to the data deletion interval is short.

If this option does not work, do not store any new data on the USB in case your original data is overwritten and cannot be restored, and safely disconnect USB from computer until you proceed to start the data recovery process.

Tips for USB lost data recovery

When faced with USB data loss, irrespective of the cause, several critical steps should be taken to maximize the chances of successful file recovery:

• Stop Usage: The moment you realize your data is lost, immediately discontinue using the flash drive. Continued use can overwrite the deleted files, making recovery more challenging.

• Disconnect and Protect: Unplug the flash drive from your computer and store it in a secure place until you're ready to begin the USB data recovery process. Physical protection is crucial to prevent accidental damage or further data corruption.

• Avoid Copy Attempts: Do not copy any data from the flash drive to another location. Such attempts can exacerbate the situation, overwriting crucial data sectors and diminishing the prospects of successful recovery.

By following these precautions, you enhance the possibility of successfully recovering your deleted files from a flash drive.

Section 1. Recover USB lost data without software

How to recover deleted files from flash drive without software? Here we list three methods to recover USB lost files without software, namely: using Command Prompt, recovering from previous versions, and recovering from a backup file. The following are the detailed guides to the three methods.

Way 1. Recover lost data from USB with attrib command

Recovering files from USB using CMD attrib command is one of the most common methods. This command line can help users to modify the file attributes of Windows files. For files and folders that are completely hidden, we can unhide them using the attrib command in a command prompt window to unhide them.

If the attrib command does not work, it is possible that your files have been permanently deleted rather than hidden. How to retrieve lost data from USB drive using attrib command? Below is a step-by-step guide.

Step 1. Connect your USB to PC, and hold the “Windows + X” keys together to choose the Windows PowerShell (Admin) option. Then, select Yes on the User Account Control screen.

Step 2. Input “attrib -h -r -s /s /d G:\*.*” and press “Enter” on the Command Prompt window. You can replace the drive letter G: with the letter of your USB disk.

Step 3. You can head to the original location to check if files are restored correctly then.

Way 2. Retrieve USB lost files from Previous Versions

Previous Versions is a Windows built-in feature that allows you to recover deleted files via File Explorer without using third-party software.

But Previous Versions are copies of files and folders that the Microsoft Windows system automatically saves as part of a shadow copy, which means you should have configured restore points or backup USB files using File History before data got lost.

Step 1. Plug in the USB flash drive to the computer and double-click on it to open it.

Step 2. Right-click the folder where you lost your data, select Restore previous versions, and choose the right backup version to tap on Restore.

Way 3. Restore files from USB via Windows backup

If you have performed backups of your USB files using Backup and Restore before, a Windows data backup and restore tool, perhaps you can restore lost data by restoring the backup files.

Step 1. Head to Control Panel and click on Backup and Restore (Windows 7) under the System and Security section.

Step 2. Press Restore my files on the pop-up screen.

Step 3. Click Browse for folders or Browse for files to find targeted files.

Section 2. Recover USB lost data with data recovery software

Way 2. Recover USB lost data with Windows File Recovery
