How to recover data from usb drive not recognized？

USB drives are a convenient and reliable way to store and transfer data. However, you might encounter a frustrating situation where your USB drive is not recognized by your computer. This can happen due to various reasons like physical damage, corrupted files, or driver issues. The good news is that, in many cases, you can recover your data without formatting the drive.

1. Problem

Before diving into the technical methods for recovering data, it’s important to understand why your USB drive is not recognized in the first place. Various factors can contribute to this issue, ranging from simple connection problems to more complex file system or hardware failures.

What Causes USB Drives to Become Unrecognized?

File system corruption: Sudden removal or improper ejection of the USB drive can corrupt the file system, making it unreadable by your computer.

Driver issues: Outdated or corrupt drivers can prevent your operating system from recognizing the USB drive.

Physical damage: Damage to the USB drive’s connectors, circuit board, or internal components may cause it to malfunction.

Power supply issues: Some USB ports may not provide enough power to read the drive properly.

Partition problems: If the partition of the USB drive becomes corrupted, it may appear unallocated in Disk Management, preventing access to the data.

Common Symptoms of a Non-Recognized USB Drive

The USB drive doesn’t show up in File Explorer or This PC.

Device not recognized or similar error messages appear when you connect the USB.

The USB drive is visible in Disk Management but listed as “RAW” or “Unallocated.”

The USB drive’s LED (if present) doesn’t light up when plugged in.

2. Precautions Before Attempting Recovery

To avoid making the situation worse, it’s crucial to take some precautions before proceeding with any recovery attempts.

Key Steps to Avoid Further Data Loss:

Do not format the drive: While the system might prompt you to format the USB drive, avoid doing this as it will erase all data on the drive.

Stop using the USB drive: Don’t add or remove files, as this could overwrite the data, making recovery more difficult.

Use a different port or computer: Before assuming the drive is faulty, try connecting it to a different USB port or another computer to rule out connectivity issues.

Things to Avoid:

Avoid using third-party disk management software at first: Some disk management tools can cause data loss if not used correctly.

Don’t force the USB drive into the port: If the USB drive doesn’t fit easily into the port, there may be physical damage that needs professional attention.

3. Method 1: Try Basic Troubleshooting

Sometimes, the solution can be simpler than it seems. Before diving into more complex recovery methods, try these basic troubleshooting techniques.

Reconnecting the USB Drive to Different Ports

Try a different USB port: Sometimes, the problem is with the port rather than the drive itself. Use another USB port on the same computer, preferably one on the back of a desktop PC for better power delivery.

Testing the USB Drive on Another Device

Try another computer: If the USB drive is still not recognized, connect it to another computer. If it works on another device, the issue may be with your computer rather than the drive.

Restarting Your Computer

Reboot the system: Sometimes, a simple restart can resolve recognition issues. Restart your computer and reconnect the USB drive after the system boots up.

4. Method 2: Check for Drive Recognition in Disk Management

If your USB drive does not show up in File Explorer, check if it appears in Disk Management. Disk Management provides a comprehensive view of all the storage devices connected to your computer, even those that are not accessible through normal means.

Accessing Disk Management:

Open Disk Management: Press Windows + X and select Disk Management.

Check for your USB drive: Look for your USB drive in the list. If it appears as “Unallocated” or “RAW,” the drive may have lost its file system or partition.

What to Do If the Drive Appears in Disk Management but Is Not Accessible:

Assign a Drive Letter: If your USB drive appears in Disk Management without a drive letter, right-click on it, choose Change Drive Letter and Paths, and assign it a new letter.

Check the file system: If the drive is listed as “RAW,” this means the file system is corrupted. You can attempt to recover data using a recovery tool (explained in Method 6).

5. Method 3: Update or Reinstall USB Drivers

Outdated or corrupted USB drivers can prevent your computer from recognizing the USB drive. Updating or reinstalling these drivers might resolve the issue.

How to Check for Outdated or Corrupt Drivers:

Open Device Manager: Press Windows + X and select Device Manager.

Locate your USB drive: Look under Universal Serial Bus controllers for your USB drive.

Check for errors: If there’s a yellow exclamation mark next to the USB drive, this indicates a driver issue.

Step-by-Step Guide to Updating or Reinstalling Drivers:

Update drivers: Right-click on the USB drive in Device Manager and select Update driver. Follow the prompts to search automatically for updated driver software.

Reinstall drivers: If updating doesn’t work, right-click on the USB drive and select Uninstall device. After uninstalling, remove and reinsert the USB drive to let Windows reinstall the correct drivers.

6. Method 4: Assign a New Drive Letter

Sometimes, your USB drive may be functioning properly, but it doesn’t appear in File Explorer due to a drive letter conflict.

How to Identify Conflicts with Drive Letters:

Open Disk Management: Press Windows + X and select Disk Management.

Look for your USB drive: If the USB drive is listed but lacks a drive letter, this could be the cause of the problem.

Step-by-Step Guide to Reassigning a New Letter to Your USB Drive:

Right-click on the drive: In Disk Management, right-click on the USB drive and select Change Drive Letter and Paths.

Assign a new letter: Click Add or Change and assign a new drive letter that isn’t already in use by another device.

Check if the drive is accessible: After assigning the new letter, check if your USB drive now appears in File Explorer.

7. Method 5: Using Command Prompt (CMD) to Repair the Drive

If your USB drive is recognized but inaccessible, you can use the Command Prompt to attempt repairs. The chkdsk and diskpart commands are powerful tools for fixing file system errors.

Using the chkdsk Command to Fix File System Errors:

Open Command Prompt as Administrator: Press Windows + X and select Command Prompt (Admin).

Run the chkdsk command: Type chkdsk X: /f (replace X with the drive letter of your USB) and press Enter. This will attempt to fix file system errors on the USB drive.

How to Use diskpart to Check the USB Drive’s Partition:

Open Command Prompt: Press Windows + X and select Command Prompt (Admin).

Run diskpart: Type diskpart and press Enter.
