I am sorry for the dificulties caused by your WD My Passport. I would recommend you to enter Disk Management and check if the drive appears there. It should appear with a drive letter and a correct file format. If there is no drive letter, try to assign one, right clicking the drive. This action should not affect your data. Do not try to format/initialize the drive. I strongly recommend you to check the drive with another USB cable and on another PC.
Hope this helps
