Windows 10: My usb drive is not working

I have this usb which has micro sd card reader in it its working i tested the usb drive on other pcs but my micro sd card cant be read by my nintendo or my android phone i put it in my windows 11 pc and now it reads but i click on it and i get error that reads "Location is not avaible A:/ is not accessible Incorrect function

:)

 

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.

 

USB boot for bios update

Did the first step. It already doesn't work. Note the capacities and drive letters M:/N: The HP utility is about to format my raid-1 volume containing my 2 750gb drives. It thinks it's the usb stick. I can not select any other drives in the HP utility. My 512mb usb stick is U:.

Any other suggestions?

 

USB not working

Hi,



Thank you for writing to Microsoft Community Forums.



This issue could occur if the flash drive is damage or Windows USB root hub is not working as expected, you can try the troubleshooting steps below to further narrow down to the root cause of the issue.

1. May I know, if the USB is working on another computer?
   
2. Which version of Windows is installed on the computer?
   
3. Are you aware of any recent changes made on the computer?
   

I suggest you to check the article
USB devices may stop functioning correctly when multiple devices connected to the same USB hub go
into selective suspend, follow the steps on this article and check if this helps you.



If you don’t have any data concern, you can
format the USB from disk manager (Applicable for Windows 10), check the topic
To format an existing partition (volume) from the article, however you will have to perform this steps on your USB drive. So, make sure the USB is connected when you perform the format, please be careful to select the USB drive, if the steps
is performed on wrong drive the data on the drive will be wiped.



If you still face the issue, please reply to this post with more information.
