How to Repair a USB Stick: Everything You Need to Know

Part 1. Can You Repair a USB Stick?

Yes. You can repair a USB flash drive if your computer can still detect it, using Windows utility tools to identify and resolve issues. The success depends on the type of damage, which is usually logical or physical.

Logical corruption affects the software. It may appear as system errors or conflicting drivers; these can often be fixed if the drive is still readable. In many cases, free tools can assist with these fixes. Check these free SD card recovery tools, which also work for USB flash drives.

On the other hand, Physical damage affects the hardware and needs professional repair. It can be difficult, and sometimes, even exceeds the drive’s value. Replacing the pen drive is the most practical solution if the damage is severe.

Part 2. How to Tell if a USB Stick Is Corrupted

A corrupted USB drive displays the obvious signs of manipulation. These can help you confirm that your device is compromised. The most common signs are the obvious error messages, such as “The directory is corrupted and unreadable” or “The disk is write-protected.” These notifications appear when you try to edit or move the content of the flash drive. Or, when you transfer photos from Android to a USB drive.

But sometimes, these messages won’t appear even if the device is faulty. In this situation, you can look for the following indications of corruption before trying to fix a thumb drive:

• Files or folders are missing
• Files or folders appearing as shortcuts
• Unable to open the USB content
• A sudden lag in the performance of the flash drive
• USB is showing up as an incorrect storage capacity
• Your computer is not detecting the drive at all

If these signs indicate logical damage, you might recover your data first. Read our PhotoRec software review for file recovery from corrupted drives before proceeding with repairs.

Part 3. How Do I Fix My USB Stick Not Reading?

An unreadable USB drive is easy to fix once you know if the issues are related to its hardware or software. Below, I’ve listed simple steps that can help you identify the problem and fix it.

Step 1. Check Physical Connections and Ports

Before you assume that the problem is technical, step back and look at the USB stick itself. Physical corruption can appear in many ways on your flash drive. Typical signs of damage are a loose connection and constantly interrupted communication between your computer and the pen drive. The best way to identify the issue is to inspect it physically.

When examining, look for these indications of damage:

• A bent or unstable USB connector
• Cracks in the plastic or metal casing
• Exposed internal components or circuitry
• Burn marks or discoloration near the connector
• Parts of the USB are separating from the casing
• Rusty metal parts in the connector or ports

Step 2. Update or Reinstall USB Drivers

The flash drive might not show any apparent damage, indicating a software problem. The initial action to tackle this issue is to verify your drivers. The computer utilizes USB drivers to identify and interact with the device. Malfunctioning drivers will impact this process. Thus, you can either update or reinstall the drivers to repair the USB flash disk. Below are the steps.

1. Press the “Windows + R” keys at the same time. This will open the Run command.
2. Type “devmgmt.msc” in the box and click “OK.” This will open the Device Manager tool.

3. From the new window, expand the “Universal Serial Bus controllers” menu. This will reveal a list of devices.

4. Right-click one by one on each driver and select “Update driver” or “Uninstall device.”

5. Restart your PC. Connect the USB device again. This will automatically reinstall the required drivers to fix the pen drive.

Step 3. Run CHKDSK to Repair File System Errors

CHKDSK, also known as Check Disk, is a built-in Windows utility tool. It looks for problems in the file system and fixes them. When you run it on a USB stick, it checks for damaged sectors, corrupted file structures, and other logical issues that can stop the drive from opening. A lot of “unreadable” USB sticks have these kinds of hidden data inconsistencies. CHKDSK can clear these out. As a result, your storage drive becomes readable again.

Here’s how to fix a corrupted flash drive using CHKDSK.

1. Connect your USB stick and open File Explorer. Select “This PC” from the left.
2. Find your USB drive name under “Devices and drives.” Right-click on it and select “Properties” from the list.

3. A small window will appear. Select the “Tools” tab from here. Then, click “Check” under Error checking.

4. CHKDSK will check the drive for any errors. The message “You don’t need to scan this drive” shows there are no errors. If you want to recheck, click “Scan drive.”

5. Wait for the scan to complete. Then, click “Show Details” to view the repaired issues.

Tip: You can also run CHKDSK using the Command Prompt. Open it as an administrator. Then, type chkdsk /X /f H: and hit Enter. Here, you can replace H with your own drive’s name. Check Disk will scan and fix issues on its own.

Step 4. Format the USB Stick as Last Resort

The USB stick may stay unreadable even after you run USB repair tools. At this point, the only option is to format the device. Formatting is the process of creating a new file system that organizes your data and gives you more space for storing your files.

Here’s how to format and repair a corrupted USB drive.

1. Go to “This PC” and head to the “Devices and drives” section. Right-click on your USB drive. Then, choose “Format.”

2. Click the “File System” dropdown and select the desired option.
3. Check “Quick Format” if you need, or uncheck it for a complete format. Then, click “Start” to format the device.

Part 4. How to Reset a USB Stick

Formatting does not completely remove all data on your drive. To completely wipe faulty partitions and restore the drive to its original capacity, you need to reset it to a factory-like state. Diskpart offers the most reliable way to do this.

Here’s how to repair a flash disk using it.

1. Connect your thumb drive. Go to the “Start” menu and open the Run command. Type in “Diskpart” and hit “Enter.”
2. Enter “list disk” in Command Prompt. You will see a list of all drives on your computer. Find the name of your USB drive based on its size.

3. Type “select disk 2” (replace disk 2 with the specific name of your pen drive) and press “Enter.”

4. Type “clean” and press “Enter” to wipe all data on the drive.

5. Next, write “create partition primary” and hit the “Enter” key again. This will restore the drive to its primary partition.

Now, close the command prompt and format your drive to restore its full capacity.
