This wikiHow teaches you how to repair a damaged flash drive (aka flash drive or flash disk). For software or driver problems, you can scan and repair your flash drive using the computer's built-in repair tool. If the disc does not work due to incorrect formatting or corrupted data, you can reformat the disc. However, keep in mind that reformatting a USB flash drive will erase all data stored on it. Finally, if the disc is not working due to physical damage, you will need to take the disc to a technology department or a professional data recovery service. If that's not possible, you may be able to fix it yourself by soldering the damaged USB disk circuitry to a working USB cable. However, repairing the disc by yourself is not really a recommended step, as you run the risk of damaging the disc.

Method 3 of 3: Repairing Physical Damage to Disk

Step 1. Understand that physical repair of a disk may not produce the desired results
Do not attempt to open a disc unless you have professional experience repairing physically damaged hard drives.
- If the disk's internal storage space is damaged, the only step you can take is to take the disk to a professional repair service.
- The cost of data recovery services varies from USD 20 (approximately 200-300 thousand rupiah) to USD 850 (approximately 10-12 million rupiah), depending on the extent of disk damage and the form of recovery required.

Step 2. Observe and look for dust or foreign objects in the mouth of the disc
It is possible that the disc cannot connect to the computer because it is blocked by objects that can be easily removed. If you see something in the mouth of the disc, remove it using a toothpick or earplug.

Step 3. Try a test disk on a USB port or another computer
It is possible that the problem lies with the faulty USB port, and not your disk.

Step 4. Prepare a repair tool to solder the damaged disc connector
If you don't mind the risk of losing files or corrupting your disc and want to repair your disc yourself, here are the tools you'll need:
- Soldering tool with solder and flux
- Old USB cable
- Scissors or cable cutter
- A screwdriver with a small flat head
- Magnifying glass or loupe for jewelry

Step 5. Remove the disc cover
Open the cover using a flat-head screwdriver.

Step 6. Use a magnifying glass to observe the circuit board (PCB) and solder pads
If the green circuit board (PCB) is damaged or the solder pads come off, you may need professional help.
The solder pads are four pieces of solder that connect the ends of the USB connector to the copper lines on the circuit board. If the connector is disconnected, but the circuit board or solder pads are not damaged, move on to the next step

Step 7. Place the disc on a hard surface
Position the end of the connector so that it is facing you, and the solder pads pointing up.

Step 8. Use scissors or a cable cutter to cut one end of the USB cable
Make sure you cut off the USB end if the hard drive cable is an adapter.

Step 9. Open the protective rubber of the USB cable wire
If possible, unscrew the 0.6 centimeters of rubber on the four wires inside the cable that is connected to the USB cable.

Step 10. Solder each wire to the four solder pads
Don't be in a rush when soldering because if you don't attach the wires tightly, it's possible that the flash drive won't work.

Step 11. Plug the other end of the USB cable into the computer
The cable can be connected to one of the rectangular slots on the computer's CPU.

Step 12. Access the flash drive on the computer if possible
If the disc is recognized by the computer, open the disc and move the files on it to the computer's hard drive as soon as possible:
- Windows - Open menu " Start ”, click the icon “ File Explorer ”, then select the flash disk icon.
- Mac - Open Finder and click the flash disk icon.
- If the disc is not connected to the computer, take the disc to the technology department to see if the department staff can retrieve the data from the disc.
Tips
- If you want to seek the services of a professional data recovery company, make sure you describe the problem as fully as possible to ensure that the company has the appropriate equipment and experience or capabilities.
- USB disks are cheap and available in many stores. If the data on the disk is not very important, it's a good idea to give a new flash disk.
- If the disc contains important data that you need to retrieve, do not reformat the disc.
Warning
- Always back up important information or data.
- Formatting the disc will erase all data stored on it.
- If the files stored on the disc are important, don't let someone else with a soldering iron convince you that they can repair the disc. Take the disc to a professional repair service.
- Always disconnect the disc from the computer before physically unplugging it from the computer to avoid damaging the files or the disc itself.
