Hi there denlov,
It's not really clear what the actual issue is. Could you please provide some more information?
Also, it would be nice to provide a screenshot of Disk Management.
What are the options that you get when you right click on the USB drive, while in Disk Management?
It would be a good idea to attach the drive to another system, so you can see if the issue persists. Also, you can try to assign a different letter, except for X or Y.
Let me know how this goes,
