    Computer can't recognize a USB flash drive after it's been removed and reinserted


    When I first boot up my Windows 10 computer, it will recognize USB flash drives in File Explorer. But once they are removed, whether simply pulled out or properly ejected, they won't be recognized again. No other flash drive will be recognized (so I know it isn't just a bad drive). I've uninstalled and reinstalled the devices in Device Manager, and I've uninstalled all three USB root hubs, both Generic USB hubs, and two USB Composite Devices. After restarting in each case, the same thing happens again. And it's only flash drives that it happens to. Dongles for my mouse and wireless keyboard are recognized always. What else can I check?

    :)

    help. USB drive isn't assigned a drive letter.

    Any usb flash drive I plug into my computer isn't assigned a drive letter. The physical drive shows in the "safely remove hardware" but it doesnt show up in disk management. I have tried to populate the volume thru the safely remove hardware properties window and it does pop up in the list but it doesn't stay there. This isn't a format or assign a letter problem. It's more complicated then that. Maybe one of the services needed for usb drive management was disabled? Suggestions needed. btw external usb harddrives work fine.

  3. USB flash not being recognized


    Even rebooting won't make my Windows 10 Home program recognize a USB flash drive plugged into any port of the computer. I've tried three different flash drives, including two that are new and one that plays in the car. I don't get that musical note that tells me the computer recognizes something that has just been plugged in.

    I'd appreciate any suggestions as to what's going on and how to solve it. Thanks, Larry

    USB Flash drive made bootable

    Hi Nelson,

    Check if there is any slide switch on the side that provides write protection. It show's a closed and open lock on each side. We suggest to follow these steps below:

    • Insert the USB flash drive into the USB port.
    • Click Start, type devmgmt.msc in the Search textbox and press Enter.
    • Find Disk Drives and expand it.
    • Find the USB flash drive you want to format, and double-click it. It opens the
      Properties dialog box.
    • Click Policies tab.
    • By default, the Optimize for quick removal option selected, switch it to Optimize for performance and then press
      OK.
    • Now open Computer. Right click on the USB Flash Drive and select Format. The Format dialog box now appears.
    • Select NTFS in the File System field.
    • Press Start and wait while the process will be completed.

    You can also connect the USB drive on a different computer and try formatting.

    Let us know how it goes.
