Windows 10: usb drive works on one computer and not another

interesting weird? problem - USB driver 16TB: operates as expected on computer 1 but read-only on computer 2. Both computers Windows 11. Computer 2: - attempted write yields drive error and drive 'disappears'. USB disconnected and reconnected restores drive. - computer 2 can format drive. - diskmgmt says drive is healthy. - diskpart can see volume and partition. - explorer can see and view files. - crystaldiskinfo does not see the drive.

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.

 

computer not recognizing usb drive

Hi,



Thank you for writing to Microsoft Community Forums.



I understand that you are unable to use USB drive on your computer. I’ll certainly assist you with this.



However, please let us know:

• Do you receive any error when connecting a USB drive?
  
• Does this issue occur only with one particular USB or with all the USB drives?
  
• Are you aware of any changes made to the computer prior to this issue?
  
• Which build version of Windows 10 is installed on the computer? To check type
  winver in the search bar on the Taskbar and hit
  Enter.
  
• What is the make and model of the computer?
  

Meanwhile, I would suggest you to refer the troubleshooting steps mentioned in the article

Error: “USB Device not recognized” except for Method 1 and 2.



Let us know how it goes.

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.
