Lexar USB flash drive is popular among people due to its better performance, reliability, affordable price, and high security. But many reported that the Lexar USB drive is not working.

The PC may have trouble detecting a USB drive a few years old or even, sometimes, a new one. Troubleshooting is quick, but there were instances where the drive had run its course, and replacing it was the only viable option. So, let’s find out all about the issue.

Why is my Lexar USB not working?

Here are some of the reasons the Lexar flash drive is not showing up:

  • Issues with the connection – If the connection between the USB drive and the PC is not proper, the drive won’t show up.
  • Incompatible or outdated drivers – Drivers play a critical part in the effective functioning of the flash drive, and if you have incompatible, corrupt, or outdated drivers, it will throw errors.
  • Drive letter not assigned – You have to assign a drive letter to each storage device, in the absence of which, it would cease to work.
  • Conflicting hardware – In some cases, another piece of hardware often conflicted with the Lexar USB drive, and, as a result, it was not working.

How can I fix my Lexar USB if it’s not working?

Before you try the slightly complex solutions, here are a few quick tricks that might work:

  • Unplug the Lexar flash drive, restart the computer and then plug it back in. This works when Windows cannot automatically fetch the best drivers for a device.
  • Try plugging the device into another port. If you have a desktop, connect the Lexar USB to a port on the back since that did the trick for many users.
  • Disconnect any non-critical hardware connected to the PC, for instance, the speakers, printers, microphones, or headphones, amongst others. A user reported that it was a webcam that prevented the Lexar USB drive from showing up.
  • Recollect if you installed any program around the time the Lexar USB first stopped working, and uninstall the app.
  • Make sure the USB port is not disabled in the BIOS. Since the steps differ for every manufacturer, we recommend you refer to the manual that came along with the PC or check the official website for the exact process.

If none of these work, head to the solutions listed next.
