Overview of Corrupted USB Drive Repair
A USB flash drive, pen drive, or hard drive is a portable storage device. This device allows people to carry their data anywhere they go and use it with various devices. Sometimes, this frequent use of the USB can cause issues, like leading the USB drive to go corrupt.
The good news is that over 90% of USB users can usually fix these USB issues alone. If your USB has an issue, the issue has to be one of the following for it to be self-treatable:
- Connect a USB flash drive to Windows 10/8.1/8/7, but the drive won't show up in File Explorer
- Windows detects the USB flash drive, but it won't open, saying the drive is not accessible.
- Windows asks you to format the removable disk before you can use it when double-clicking on the drive.
- Other unfamiliar errors like RAW, no media, etc.
Basically, there are two scenarios when there's an issue with your USB drive: either Windows detects your USB drive, or it doesn't detect it. The solutions differ for each issue type.
If your computer can still detect or recognize your USB, you can try to fix the logical error using the native Windows tool, CMD, or third-party fixing tool. Then you will be able to access your USB.

If your USB drive is physically damaged and cannot be detected or recognized, reinstalling the USB drivers is worth reinstalling to see if this fixes the issue. Or, you can try and fix the broken USB drive by yourself.
Method 1. Reinstall USB driver
Many strange USB issues usually results from a corrupted driver. You need to reinstall a new driver by following the steps.
Step 1: Press the Windows + X keys and select Device Manager from the menu.
Step 2: Expand Disk drives, right-click the name of your removable disk, and select Uninstall.
Step 3: Select OK and disconnect the USB drive from your computer.
Step 4: Restart your computer and connect your USB drive to your computer. Windows will automatically install the required drivers for you.
Method 2. Manually Repair the USB Drive
Here are a few things you should know before attempting to fix a broken USB drive by yourself:
- Physically repairing a flash drive is unlikely to work unless you have professional experience in repairing physically damaged flash drives.
- If the flash drive's internal storage is damaged, your only viable option is to take the drive to a manual repair service.
- The prices for data recovery can vary from $20 - $850 based on the severity of damage done to the drive and the type of recovery required.
If you decide to give this a try, follow these instructions:
- Soldering iron with solder and flux
- An old USB cable
- Wire cutters/strippers
- A small flathead screwdriver
- A magnifying glass or jeweler's loop
Once you have these required items, follow the steps to repair your broken USB drive.
Step 1: Remove the flash drive's casing. Do this with your flathead screwdriver.
Step 2: Use the magnifying glass to inspect the circuit board (PCB) and solder pads. If the PCB (the green circuit board) is damaged or the solder pads are lifted, you will probably need the help of a professional.
Solder pads are the 4 bits of solder that connect the USB connector's prongs to the circuit board's copper lines. If the connector has broken away without causing damage to the PCB or solder pads, continue to the next step.
Step 3: Set the flash drive on a hard surface. Do so with the connector end facing you and the solder pads facing up.
Step 4: Use wire cutters to cut one end off the USB cable. Ensure you cut the USB end of the flash drive cable is an adapter.
Step 5: Strip away a section of the USB cable's wire. Try to expose about 0.25 inch (0.6 cm) of each of the four wires inside the cable attached to the USB cable.
Step 6: Solder each of the four wires to the four solder pads. Take your time while doing this since failing to secure the connection adequately will most likely render your flash drive inoperable.
Step 7: Plug the other end of the USB cable into a computer. It should fit into one of the rectangular slots on your computer's housing.
Step 8: Then, you can open your USB drive. If your flash drive is recognizable by the computer, open it and move your files to a safe place as soon as possible. If the files are missing, you can move to Step 2.
