My USB flash drive was working perfectly fine until I plugged it in the back of my school computer to show my project.

The USB flash drive did not show up there. When I brought it home and plugged it into my computer, it also it did not work.

It shows up like this:

It does not has any physical damage.

I tried:

Formatting with diskpart but:

Checking the partition manager:

I used all these tools from usbdev.ru and other websites:

I also used ease US partition manager and the simple things like plugging into another USB port and checking drivers. Unfortunately none of them worked.

Although I can perfectly read and write it with the help of my Android phone as shown in the, but not in my Windows PC.

Searched everywhere but did not find a solution. I know there are experts out there so if any one could help me, then I would be very grateful to you.

I also tried other questions which were also available at superuser but none of them worked. So please don't mark this as a duplicate question.

Update: I tried some more tools like JetFlash Phision, Bootice, HP USB disk but none of them worked. Although there is probably a problem with the NAND of the drive and I probably need a way to reset it. IDK if that info helps.

Also here is the picture of what shows up in Alcormp: enter image description here

  • Are you able to try it on a different Windows PC, or even a different port than the one you were using? I see the first failure was on a different computer, so I'm asking about a third one.

  • May be the phone only supports USB 2 and the stick has a defect in the USB 3 system? test your stick with multiple PCs and different USB ports. If it can not be accessed then consider it defect.

  • A failed disk may behave differently on the phone and the PC. It's still failed and dangerous to use on the phone.

    I would try with a Linux live usb (supposing you have at least two usb ports)

    Does this answer your question? USB flash drive not working or is appearing as an empty disk drive, Disk Management reports "No Media" with 0 bytes size

The screenshot of the MPtool is pretty conclusive evidence the NAND chip is not detected. It's either dead or not properly connected. The USB flash drive can't be repaired.

USB drives die without warning.

That appears to be what happened here.

Can you recover the files on your phone?

Otherwise for Windows, if it will not format (as per your post), then you need to replace the drive. Windows format is different than Android format.

I have had this happen before on USB drives on Windows computers.

I do not depend on USB drives and keep backups to ensure no data loss.

    I still believe its not dead due to the fact that it works perfectly fine on my phone.

  • If it will not format on Windows, then it is very most likely not usable on a Windows computer. I have had that happen before

  • Doesn't Android use FAT32 or exFAT for external storage?

  • The formats are not identical and my overall point (and emphasized by @harrymc in a comment) is that the failure the USB key does have means it is dying and on the way out.
