How to Fix USB Flash Drive That Is Not Recognized
If your USB isn’t visible with the correct size in Disk Management, recovery won’t be possible. But, there are a few solutions you can try to make it readable. The below methods will help you understand how to fix a USB flash drive that is not recognized.
Method 1: Isolate the Problem
Before troubleshooting, you must first identify what is causing the problem. Determining the source of the issue can save you a lot of time that would otherwise be spent troubleshooting areas that aren’t relevant.
To do this, you must test the USB in a different port to see if the port you’re using is faulty. If another port doesn’t work, then you should try connecting the USB to another device to make sure it’s not a problem with the device you’re connecting to.
If the USB works fine when connected to another USB port or device, then the problem isn’t with your USB. If the USB still isn’t being read, try the next method.
Method 2: Connect Directly to the Motherboard
The USB ports on your computer’s case, typically located at the front or top, connect to your motherboard using internal wires. These wires could have been damaged at some point, resulting in any device connected to the USB ports on your computer case becoming unreadable.
To avoid this, try connecting directly to one of your motherboard’s USB ports on the back plate of your computer if your USB thumb drive is not recognized. This way, you can ensure you’re getting a direct connection and avoiding any complications with the internal wiring of your computer case.
Method 3: Clean the USB Contact Points
Physical substances like dust and dirt can build up over time. This can lead to a physical barrier that blocks the connection between your USB and USB port. Regularly cleaning your USB and USB ports can prevent this.
If you want to remove dust, use an air duster or can of compressed air to blow the dust out. For other, more persistent obstructions, lightly wet a cotton swab with isopropyl alcohol and gently clean out the USB or port. Once complete, let it dry completely before use. Be mindful of how delicate the USB connections are and only clean USB ports when the device is powered down.
| Method of cleaning | When to apply |
| 🌪️ Compressed air | Save method to remove dust |
| 🥢 Toothpick or similar narrow object | Best for removing stuck dirt |
| 🍾 Alcohol | Ideal for removing sticky mess |
Method 4: Hardware Troubleshooter
Windows comes with lots of powerful troubleshooters that are designed to target specific problems. The Hardware and Devices troubleshooter can scan your computer for issues pertaining to your USB and fix them so you can access a USB drive that is not recognized.

Method 5: Update or Reinstall the USB Drivers
Any hardware you connect to your computer requires a driver. Drivers establish and maintain communication between your devices so you can actually use them. If your USB’s drivers are corrupted or out-of-date, it may result in your USB performing erratically, or your flash drive not showing up in Windows 10 at all.

Method 6: Reinstall USB Controllers
A USB controller is responsible for managing all your USB-connected devices, like your keyboard, mouse, and USB flash drive. It works with your device’s driver and helps your system understand how to use the device. Without it, none of your USB devices would work, even with their own drivers.
Reinstalling your USB controller can also help re-establish communication between your system and USB. Follow these instructions to reinstall your USB controller.
- Right-click Start and click Device Manager.
