Fix 7. How to Manually Repair the USB Drive by Yourself

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 to 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.
