Some USB->SATA bridge firmwares are broken, just swap it out with a different model and it'll be fine (though it may be difficult to do this with a WD Passport drive without taking the drive apart and placing the drive in a generic USB drive enclosure).
There are even drives with the USB bridge built-in and no SATA connector at all...
Also watch out for weak power supplies on Raspberry Pi boards. The CPU and memory run at a significantly lower voltage than the USB interface, and one symptom of a power supply that is too small or too old is that all the USB devices stop working reliably.
This is probably the most important advice. On Raspberry Pis + HDs, weak power supplies are the major problem providers.
I happen to have a different device, an HP Pavillion Detachable X2 (tablet PC-like) on which one of my USB HDs, one I made myself by putting a 2"1/2 SATA HD in an USB enclosure, will disconnect everytime I try to use it without having the laptop powered by its AC power supply...
It uses BTRFS and gets USB disconnected at first attempt to write or remount the FS. But this never damaged the FS.
