To resolve this, go to Control Panel>Administrative Tools>Computer Management>Disk Management. Note the drives on the right windowpane. See if the Kingston (x) is recognized. (x) denotes the drive letter that Windows assigned for the DataTraveler.
If the DataTraveler is using the same drive letter as one of the other drives, right-click the Kingston Drive letter and click on "Change Drive letter and Paths".
