Hi udara.
Your drive maybe corrupted and un-repairable for reasons unknown. I've seen it where the drive is removed while being written too, not saying you did this just I've seen it. I always eject USB devices.
That said please open Disk Management by right clicking on start, then "Disk management".
How does your Pen Drive show? Since you were planning on formatting can you right click on drive and Delete the volume. Then recreate and format. Please do a full format by removing the check mark beside "Quick Format"
Failing that you could try Diskpart. Diskpart has to be used with extreme caution because if you get the disk or volume wrong it will not warn you, it will act.
Here is a tutorial.

On a related note about watching which device (or which partition) is being acted upon...
I gave each of my internal and external hard-drives, usb flash drives, cd/dvd drives, unique names. And, every non-system-boot partition was given a unique name. That way, regardless of drive letter shuffle, regardless of usb or dvd boot, I knew what any particular program or utility was "aimed at" before doing the action needed.
If the drive is bad, it's bad, but having nothing to lose, un-tick Quick Format and see what happens. And oddly enough, you might also restart the PC before trying again. Again, having nothing to lose, and being quick and easy.
I've found Windows 10 sometimes needs a restart to work out odd quirks at times.
My two cents.
Hi Udara,
Is your Kingston Data Traveller DTSE9 a 16GB flash drive or 8GB Flash drive?
Have you at anytime used it as a bootable device?
Have you partitioned it?
Please post a screenshot of Windows Disk Management. ( Plug in only your Data Traveller. Remove all other USB storage devices)
I am off to Bali tomorrow and shall return only on 08th June midnight. If you are not able to resolve the issue with the help of other experts here by then, we shall continue after 8th.
