Windows 10: USB disk not working

I have installed 2nd os with my USB, I have made it bootable. I want that USB back to normal. I have quick formatted it with the FAT file format. It was successful but when I try to open the USB. It says to insert the disc even though it is inserted.

And that's it, boot off your usb disk

 

How To Format A Write Protected Flash Memory ?

¿You already tried this one?...

Run CMD


1. diskpart
2. list disk

Then in the 3º step, put the correct number of disk in the list for the usb flash (if it's listed in disk 3, then you'll have to write select disk 3).

2. select disk #
3. clean
4. create partition primary
5. select partition 1
6. active
7. format fs=fat32
8. assign
9. exit

with that commands you will format the flash drive in fat32, if you have a large drive you can select also "format fs=ntfs" in step 7.

good luck!

 

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.
