catching a car fire in the parking lot […] notifying […] employees so they could move their cars, preventing the loss of hundreds of cars.

Does it only happen with these two drives? i would try with some other HDD/SSDs or two usb sticks. that way you can test if its some weird hardware incompatibility that sometimes happen between specific devices or if the board wont support more then one connected usb drive in general.
