Yes (i have tested several WD Portable Drives, All different Sizes [Ultras, Elements, Pi Drives etc] … and they all work fine)
But … 3 Things
- You must have at minimum a 2A 5V Power Supply [a good quality one]
- Only One Portable HDD will work at a time (but you can plug in as many externally powered as you want)
- You also need to add the following lines inside the config.txt on the SD Card
max_usb_current=1
safe_mode_gpio=4
My Passport Ultra is on loan to a family member … but here’s a pic of my 2TB WD Elements with a Voltage Tester connected to the Raspberry Pi 3 to give you an idea of of the Current Draw, Voltage, Amps etc …
