Some Flash Drive Error Messages That Should Put You in a Panic Mode Include:

  • "Please insert disk into removable disk."
  • "Format Disk" and of course."
  • "USB Device Not Recognized or Malfunctioned."

You may have to forget about your disk if you see some of these error messages on your screen, or if your USB flash drive is not showing up or not detected. Your drive could be dead, and the best thing to do is to recover data or files contained in it.

How to Fix a Malfunctioned USB Flash Drive that is not Recognized or Detected

There are several ways to fix your storage device based on the problem it has. Some of the problems are minor, but may give you a hell of a headache. Save yourself from unnecessary stress by learning numerous ways of repairing your drive.

The problem with your flash disk could be due to damaged port or slot. You can insert the pen drive in another port to see if it can work. In fact, this is what you should always try first when your storage stick has issues. You can then perform a USB port repair if you find this is the problem.

To fix the port problem, follow this procedure: Start> Control panel> Hardware and Sound> Device Manager> Universal Serial Bus> Uninstall> Enter> Scan for hardware changes (click on the blue icon to reinstall).

Your mass storage device could also be unrecognized because of using it in a computer with a different bit. If your drive was written by a 32 bit computer, it may not work on a 64 bit computer and vice versa. So know your computer bit in order to use the right flash stick.

The disk could also have been encrypted on another device. An encrypted drive is protected by a password. Use the device which encrypted the disk to fix the problem. Just enter the encryption password and your storage stick should work.

A damaged USB interface or cable can also make your storage device show the "malfunctioned" error message. Use another cable to see if it can work. Also try on another interface. Your device should work if the issue was with the cable or interface.

If your drive has corrupt partitions, you will definitely get one of the above error messages. Use the Disk Management tool to see the status of the partitions. If they are not "Healthy", use tools such as TestDisk and PhotoRec to fix the problem.

Follow this path: Start menu> Disk management> Create and format hard disk partitions> Removable disk.

Alternatively: Press Windows key and R together and type in "diskmgmt.msc", then Enter.

If your mass storage stick is lacking a drive letter, you can also have the error messages appearing on the screen. The common message here is "USB drive is detected, but not showing in My Computer."

Follow this path to fix the problem: Press Windows key and R together and type in "compmgmt.msc", then go to Disk management (find your disk) > Change Letter and Paths (right click) > Change> Add Letter (choose an unused letter).

Download the latest software or update the existing one to solve the problem. But first, check if the problem is with the drive system.

Press the Windows key and R together and type in “devmgmt.msc”, then Enter. You can also type in "dev man" in the search box of the Start menu.

Check for a yellow triangle and black exclamation mark on the driver’s icon. This symbol shows that a driver tool has a malfunction. Learn more about the problem on "Properties."

Try installing the latest tool to see if the USB stick can work. You can also update the software. Click on the "Update Driver" for the Windows to find the right update.
