It appears in 'Devices and Printers' and 'Device Manager' but not in 'Devices and Drives' in File Explorer nor in Disk Management. When I first plugged the drive into the Lenovo, it was instantly recognized and added.
I just got a brand new Lenovo Flex 14 Laptop with Windows 10 and am unable to use/access the content on the WD My Passport Ultra external drive that I have all my stuff from my old Macbook backed up on.
