Windows 10: Usb flash drive not showing

I have a dell laptop with windows 11. I have 3 brand new scandisc flash drives, none of them appear in file explorer. The laptop makes a sound when the flash drive is connected/disconnected. In device manager the drive is in the usb section and shows “working properly” there iis also an unlnown device with a caution symbol. The device shows in disc manager but does not have a drive letter. I have tried uninstalling the device in devive manager and restarting, disc management will not let me assign a drive letter. I have run windows update, checked the drivers are ip to date etc. The drive work

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.

 

USB Flash Drive Not Recognised

To find what Navy suggest:: Open a CMD window as administrator and type: diskpart list disk (it will list all drives. Identify the USB drive number) select disk n (replace n by the USB drive number obtained with list disk) list part (is there more than one partition?) select part 1 detail part (is it ntfs or Fat32?) exit

 

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.
