WD Passport only works on USB 3.0 ports

Hello,

My recommendation will be to try it with another USB cable, if possible please try another USB 3.0 cable to verify if the issue remains or you can also try a USB 2.0 cable to verify if the drive will be seen on a USB 2.0 port using a USB 2.0 cable. Also for troubleshooting purposes please try it on another operating system (Windows XP or Vista)
